A USB flash drive with activity light gives the user visual feedback the device is working.

Click here to buy a USB flash drive with activity light. While on this site, consider some other advanced functions you might need, but didn’t think of. Advanced functions such as:

• Maybe you want the USB flash drive to be read-only (write protected)
• Maybe you want the USB to act like a CD-ROM drive
• Maybe you need to copy protect files on the drive – meaning people can view the files but they cannot print them, save them, screen capture, share, etc. The files can only be viewed.

These USB flash drives use an activity light and also provide the other cool functions mentioned above. The landing website offers six different body styles and an unlimited number of body colors along with free printing / branding if required.

Many small and portable flash drives do not have an activity light and we don’t like those types of drives. They don’t give the visual feedback we want to see.

Benefits of a Blinking LED Light on a USB Flash Drive

• Data Transfer Awareness: A blinking LED lets users know data is actively being read or written. This helps prevent premature removal of the drive, which can corrupt files.
• Visual Confirmation: The light confirms that the USB device is properly connected and receiving power from the host system.
• Diagnostic Aid: If the LED never blinks or stays off, users can quickly determine there’s a connection or drive failure without launching Disk Management or File Explorer.
• Multi-Drive Management: In environments where multiple USB drives are used at once—such as duplicator stations or kiosks—a blinking light helps identify which drives are in use versus idle.
• Security Awareness: In high-security environments, a blinking light can alert users if a USB drive is unexpectedly being accessed, suggesting potential unauthorized read/write activity.

The people who write for this blog prefer a USB flash drive with an activity light. The USB manufacturers have different settings for the LED activity light. Here is a screen shot of the mass production software tool used when making a flash drive.

There are two main settings for a USB activity light:

• On or Off setting for the LED on when device is ready
• Blink or not when flash memory is being accessed (this is for either read or write)

In our experience any USB flash drive with an activity light will have both of the above settings to On. Meaning the LED will be a solid color when connected and ready, and will blink as the device is being accessed for either a read or write request.

The most common LED color of a flash drive is red. However, we have seen green and blue LED lights on occasion. Most flash drives can be customized with specific LED colors if required. Lead times and pricing might fluctuate depending on what is required.

Using very simple and inexpensive items, create a USB power hub station for all gadgets like headphones, chargers, GPS units, GoPro camera’s and more.

In addition to a very organized solution, the DIY USB power hub station is out of the way, yet easily accessible. No more taking up valuable kitchen counter space with cluttered gadgets and a birds nest of cables.

The solution is ultra-easy. For the DIY USB power hub station all you need is a shoe rack for the closet, a USB hub and your cables.

In less than 10 minutes you can be organized, powered and out of sight. This DIY project was less than $35 dollars.

First, grab a hanging shoe rack from Amazon. I found this 10 slot shoe rack for $13.

Next, grab a USB hub that only runs power (less expensive) and I found a matching 10 socket version for my 10 slot shoe rack for $20.

The only thing left to possibly buy are cables. However, you probably already have the powering USB cables required for your devices. I do think getting cables that have a combo Apple Lightening cable and microUSB cable allow things to be a bit more flexible when connecting various devices.

Here is a set of two cables with three different connectors (Lightening, USB-C and microUSB) for $6.00 (each) $13 total.

Once your items arrive the assembly is literally two minutes. There is a good chance it will take longer to clean out your closet than assemble the DIY USB power hub station.

The best location would be in the closet under your stairs. This is true because the space most likely has a power outlet.

• Step 1 – Cut a small piece of fabric in the back of each shoe rack slot
• Step 2 – Place USB powered hub in the bottom shoe rack slot
• Step 3 – Lay out the shoe rack and thread each power cable from the USB hub to each shoe rack slot
• Step 4 – Place devices in shoe rack slots and connect
• Step 5 – Hang USB power hub charging station in your closet

This how to tutorial describes a simple way to check for bad sectors on a USB flash drive. The instructions below will also fix any bad sectors, if possible, during the scanning process.

A bad sector on a flash drive is a portion of memory on the flash drive which cannot be accessed, written to, or read from and therefore cannot be used. A bad sector on a flash drive sounds easy enough to diagnose, but it’s important to know there are two types of bad sectors: hard and soft.

Physical damage to a USB flash drive will create a hard bad sector. A hard bad sector cannot be repaired or fixed and is typically induced from physical abuse. A good example: leaving a flash drive in your pocket and it went through the wash, or the device was dropped and hit the ground. In both cases, physical damage happened to the memory.

A soft bad sector on a flash drive are memory logic problems. A soft bad sector can occur from a software or data error during the write process. In lower quality flash drives, it is possible the incorrect firmware was written into the USB controller ROM and thus creates instability via soft bad sectors.

Bad sectors cannot be repaired; however soft bad sectors can be repaired.

The soft bad sectors can be fixed by using the CHKDSK utility in the Windows operating system. This same utility will also flag any hard bad sectors not to be used again, and of course not repaired.

Some signs of a bad sector on a flash drive include:

• Cannot read a file on the flash drive
• A file location is no longer available
• Unable to format the USB flash drive
• A disk read error occurs during operation

In our opinion, run the check disk one time to see if your issue is resolved, but if subsequent scans are required, we recommend discarding the flash drive to avoid further issues.

Running the chkdsk scan is really easy:

Insert flash drive to computer

Using Windows Explorer navigate to the drive letter

In the Explorer window type cmd and press enter

Once inside the command line utility type chkdsk d: /f /r /x and click Enter. NOTE: *The letter d represents the drive letter of the flash drive.

• The /f parameter tells CHKDSK to fix any errors it finds.
• The /r parameter tells Windows to repair/restore bad sectors (if possible).
• The /x parameter unmounts any “handles” to the drive or said another way, this step will not allow any other resource to access the flash drive during the scan.

It’s been reported for more than four years that Apple has been trying to solve non-invasive blood glucose testing — and continues to run into problems.

Apple has not disclosed the specific technical issues during development, but it’s almost certainly due to inconsistent test readings. In other words, whatever method Apple is using to estimate blood glucose levels is not reliable enough to meet regulatory approval standards.

Hey Apple — if you want to solve your glucose testing problem, listen up.

It is well documented that blood glucose levels correlate directly with blood viscosity, or how thick and fluid the blood is.

Our take is that Apple’s current sensor approach isn’t accurate enough to determine viscosity, which makes reliable glucose readings impossible.

That makes sense when you consider where Apple Watch sensors are located. They’re attempting to measure through skin that’s simply too thick — the wrist.

Here’s the hot tip for Apple (@AppleHCG @tim_cook):

Forget using the Apple Watch itself as the primary sensing device. What Apple should build is a mouthpiece accessory that communicates with the Apple Watch and scans the lingual frenulum.

The lingual frenulum is the thinnest skin on the human body, making it ideal for optical scanning. Measuring opacity in this area would allow for far more accurate assessment of blood viscosity — and therefore glucose levels — than scanning through the wrist.

The mouthpiece would sit under the tongue with a sensor aimed directly at the lingual frenulum. It would scan blood circulation and analyze color and opacity to determine glucose levels in real time.

This under-the-tongue device would only be used when a reading is required. The scan itself would likely take no more than five seconds.

For accuracy, the mouthpiece would read from both the left and right sides of the lingual frenulum. Higher blood viscosity results in darker, denser blood and greater opacity. Lower glucose levels produce lighter, less opaque blood.

The mouthpiece would communicate wirelessly with the Apple Watch to transmit the glucose reading.

Obviously, this is not a finished product design. Engineering, validation, and clinical testing would need to be handled by Apple’s healthcare team. That said, this concept points in a direction far more likely to succeed than wrist-based optical sensing.

If someone at Apple reads this article, we hope they have the integrity and respect for original ideas to reach out. gmo (at) getusb.info

Hold USB Flash Drive in a DVD Case

This is a brilliant solution that, after watching the video, will make you say, “This should have come out years ago!”

It is the least expensive — yet most secure way to hold a USB flash drive in a DVD case.

The era of CDs and DVDs is coming to a close, with USB flash drives taking their place. Yet many CD and DVD duplication facilities still have shelves full of DVD jewel cases that need a new purpose. The DVD-to-USB Insert card is a quick, easy, and low-cost solution.

The insert allows users to keep their existing DVD cases and printed artwork exactly the same, while securely holding a USB flash drive inside the case instead of an optical disc.

Many businesses continue to prefer DVD cases because they make excellent storage containers. The case size is practical, and the thick spine provides space to clearly label the contents.

This solution allows you to continue using that same “library-style” organization with the DVD-to-USB Insert card.

As shown in the video above, the insert can securely hold two USB flash drives inside a single DVD case. The DVD-to-USB Insert is made from clear plastic with a thickness of 0.65 mm — the same diameter as a DVD disc.

The clear plastic insert includes two inverted rectangular cutouts designed to hold nearly any USB flash drive. It accommodates drives up to approximately 3 inches long, 3/4 inch wide, and 3/8 inch thick (for metric users: 76 mm long, 21 mm wide, and 9.5 mm deep).

A center hole, the same size as a DVD disc hub, allows the insert to snap securely into the DVD case’s retention clip. Using virtually any standard DVD case on the market, the USB flash drive remains firmly in place and will not fall out during shipping or transit.

To be clear, the DVD-to-USB Insert includes only the clear plastic insert that holds the USB flash drive using the DVD case’s center snap. The DVD case itself is not included, as this solution assumes the user already has DVD case inventory.

This method of securing USB flash drives inside a DVD case does not infringe on patents held by other manufacturers using alternate retention designs.

There are two popular methods to get large videos off your iPhone.

The most common problem is having a large video on your iPhone that you need on your computer. Email programs usually limit file sizes to around 20 MB, so if the file is larger, what can you do?

Two popular options come to mind: using QuickTime or using a USB flash drive.

Option #1

Use QuickTime. Macs already include QuickTime in the operating system, but Windows users must install it. Before choosing this as your preferred method, here are a few things to consider:

• You must back up your iPhone through QuickTime before accessing the video
• You need an authorized computer to perform the backup
• Windows users must download and install QuickTime
• QuickTime is an invasive program that many Windows users dislike
• This is not a portable way to move videos off your iPhone
• However, this is a free solution

Option #2

Use a flash drive.

Yes, you need to purchase a specific flash drive, but after this one-time investment it becomes far easier to move videos off your iPhone. Some advantages worth considering:

• Transfer large videos without using a PC
• Share videos immediately with another user’s computer
• Use the drive as external storage for video backups

Point number one is really the value in all of this ?.

While you won’t be able to make the transfer immediately without the hardware, once you have the USB device the process is quick and repeatable.

Certain USB drives include software that works with iOS, allowing files to be copied directly from the phone to the drive. The device tested here is the SanDisk iXpand flash drive with 128 GB capacity, which typically costs around $40.

The process is very straightforward:

• Download the iXpand app from the Apple App Store
• Connect the flash drive to your iPhone
• Select the files you want to transfer

Seagate offers a 40 TB expansion solution that is truly plug-and-play. At first glance, 40 TB may seem excessive, but when you break it down into real-world usage and modern content demands, it may not be as much as it sounds.

To illustrate the point, consider a family of four — two parents and two young children, ages two and five.

At that age, video recording happens almost daily. If it doesn’t, those parents are missing out on moments that are nearly impossible to recreate later.

Using an iPhone set to record video at 4K resolution and 24 FPS (frames per second), a one-minute video consumes roughly 270 MB of storage. If a parent records a four-minute video once per day for a year, that results in about 360 GB of data — roughly one-third of a terabyte.

Before continuing, it’s worth noting that the Seagate solution includes software that automatically syncs mobile devices with the storage system. Large videos can be difficult to move off an iPhone without a cloud or streaming backup service, and Seagate provides that capability. We also published an article covering manual transfers using a SanDisk USB iXpand device.

Given the age of the kids, a four-minute video is probably short for whatever funny or chaotic moment is unfolding. Rounding up to ten minutes of video per day, per parent, puts daily storage consumption at roughly 5.5 GB.

You could reduce resolution from 4K down to H.264, but who really wants to do that? High-resolution video is useful for editing, and five years from now today’s 4K footage may feel low resolution.

As the kids get older, they’ll start contributing their own videos to the Seagate storage system. The examples could go on, but the takeaway is simple: as technology improves, the amount of storage required to preserve our digital content grows right alongside it.

As a closing thought, consider how difficult and time-consuming it can be to migrate data from one storage device to a newer, larger one. While a 40 TB expansion may feel like a big purchase today, upgrading from a smaller system later often takes longer — and is more painful — than expected.

The Empire State Building stands at a total height of 1,454 feet, with an interior volume of about 37 million cubic feet.

If you take a swivel USB flash drive (the world’s #1 selling body style) measuring roughly 57 × 19 × 10 mm, it is theoretically possible to fit about 17,760,000,000,000,000 quadrillion flash drives inside the Empire State Building.

Would this be a good conversation starter at a cocktail party?

GetUSB.info researches USB products every day from every corner of the internet. While we don’t publish every finding, the research continues with a focus on delivering value to our visitors.

Over the past six weeks, we’ve seen an increasing number of products described as a USB splitter. This trend makes it worth explaining what a USB splitter actually is — or more accurately, what it is not.

A USB splitter does not split a USB signal. The most common use of the term “splitter” comes from telephone hardware, such as a phone splitter for an analog signal. In that case, a single phone line can be split so the same analog signal reaches two phones at the same time. USB does not work this way — at all.

What many sellers call a USB splitter should actually be called a USB hub. A USB hub consists of one upstream port and multiple downstream ports. The upstream port carries the incoming signal, while the downstream ports make that signal available to connected devices. The key phrase here is “available,” because not all ports can receive or use the same upstream signal simultaneously.

For example, if audio is playing from your PC to a USB speaker, a hub will not automatically split that audio signal to multiple USB speakers connected to the same hub. The same limitation applies to video and data. USB signals cannot be automatically duplicated across multiple devices.

Calling a USB hub a USB splitter is a poor choice of words. In fact, we consider this a red flag and a reason to avoid buying products from suppliers who use misleading terminology to describe basic USB hardware.

The closest thing to a true “splitter” is a USB Y-cable. A USB Y-cable has two connectors on the upstream side and a single connector on the downstream side. However, both upstream connectors do not transmit data. One connector provides both data and power, while the second connector supplies additional power only.

This configuration is commonly used with external hard drives (traditional disk drives, not solid-state drives). The purpose is to draw additional power from the host computer using two USB ports and deliver that extra power to the external device.

As shown above, the idea is to connect the two USB Type-A connectors to two USB ports on the host computer, while the single USB connector attaches to the peripheral device. This setup allows the device to receive additional power beyond what a single USB port can provide.

A computer virus is something we all strive to avoid because we understand the consequences and the amount of time and energy required to restore a computer to its original condition. In a recent poll by GetUSB.info when asking users to name the top three ways a computer can get a virus, they responded with:

• Link from an email
• Link from an unsecure website
• USB flash drive

However, if Nexcopy has anything to do with the last answer, a computer virus which spreads by USB flash drive will be a thing of the past.

Nexcopy is a US company based in Southern California who specializes in flash memory duplication equipment, printers, FDA compliant flash drives, copy protection and now a road-blocking malware on flash drives.

A virus will spread via a USB stick because the device is writable. In fact, any device that is connected to a computer which is writeable could spread a virus; other devices such as external hard drives, SD cards, microSD cards, etc. all have the same potential for harm.

But what happens when you turn these storage devices on their head and not allow them to be writable in the first place? This simple yet obvious solution is a gigantic step in the right direction for controlling the spread of a virus via USB.

The Lock License flash drive designed and manufactured by Nexcopy is exactly that. The Lock License drive is a USB stick which is always write protected. The device doesn’t care what it’s plugged into, or when, or how, the Lock License drive will always be read-only.

A virus will spread in a very specific way. A virus is designed to scan newly connected devices and ping them to see if they can spread (if the device is writable). A new device is defined by any computer system when “power” is assigned upon connection, which, coincidentally is the same time the virus will try and spread.

In the world of physics, heat represents resistance. Think about touching your car tire before you’ve driven anywhere — it’s cool. Touch that same tire after driving to the store and it’s warm. That warmth is resistance.

Copper found in USB connectors and USB cables is the material where this resistance shows up. As copper heats up, data transfer rates slow down because heat represents inefficiencies in the material.

Research presented at February’s IEEE International Solid-State Circuits Conference by lead author Jack Holloway, along with co-authors Ruonan Han and Georgios Dogiamis, introduced a data transfer system capable of transmitting information up to 10 times faster than USB. The new link pairs high-frequency silicon chips with a polymer cable as thin as a strand of human hair.

Mr. Holloway explains, “Copper wires, like those found in USB or HDMI cables, are power-hungry — especially when dealing with heavy data loads. There’s a fundamental tradeoff between the amount of energy burned and the rate of information exchanged.”

The most commonly suggested alternative to copper wiring is optical fiber. Optical cables rely on photons and are extremely efficient, but the challenge lies in how photons interact with silicon chips. Because photons don’t interface cleanly with silicon, a direct connection between a fiber-optic cable and a computer chip is not ideal.

The technology developed by Holloway and his team uses a plastic polymer material that performs exceptionally well at sub-terahertz frequencies. These very high-frequency signals make the polymer a competitive alternative to fiber optics.

To complete the system, the team engineered a low-cost silicon chip that pairs directly with the polymer conduit. While traditional silicon chips struggle at sub-terahertz frequencies, this new design generates high-frequency signals with enough power to transmit data directly into the conduit. The clean interface between chip and conduit allows the entire system to be manufactured using standard, cost-effective processes.

Physically, the plastic polymer conduit is about the same diameter as a human hair.
