Pros and Cons of the Raspberry Pi USB 3 Hub

It is common to hear Raspberry Pi owners want more USB ports. GetUSB.info just read about them introducing an official 4 port USB hub. Sweet. To note, most Raspberry Pi single-board computers, except for the Raspberry Pi Zero and A+ models, include a built-in USB hub that splits one USB connection into several USB Type-A ports. Just recently they launched the official Raspberry Pi USB 3 Hub, a high-quality USB 3.0 hub that offers four additional USB ports.

This hub includes a single upstream USB 3.0 Type-A connector with an 3 inches (8 cm) built-in cable. The “upstream” port is the socket used to communicate with the host device, which in this case is the Raspberry Pi. It also has four downstream USB 3.0 Type-A ports and can reach data transfer speeds up to 5 Gbps. There’s a USB-C socket for an optional external 3A power supply but that isn’t included with the $12 purchase. Quick note, the downstream port is are the sockets used to communicate with the devices, like a USB flash drive, hard drive, mouse, keyboard, printer, etc.

One driving force on why Raspberry Pi wanted to sponsor their own USB hub is the fact most ‘other’ hubs are just too expensive. One fundamental goal of Raspberry Pi is to provide an unparalleled offering for computer code development and the lowest possible price. Usually, you either pay a high price for a reliable, well-designed product, or you buy a cheaper option that’s unreliable, doesn’t work with various devices, or simply looks bad.

With this hub, there is no “race to the bottom,” where cheap, poor-quality products pushed out better options, and online marketplaces like Amazon became filled with low-quality hubs. To offer a better solution the Raspberry team got together with with Infineon to source a quality hub chip called the CYUSB3304.

Based on user beta testers and user comments here are the pros and cons of the Raspberry Pi USB 3 Hub:

USB-C Cable Tester Sets the Bar High

Review: USB-C cable tester by BLE caberQU

USB-C cable tester by BLE caberQU

USB-C has firmly established itself as the universal connector standard, integrating data transfer, power delivery, and video output into a single interface. With so many cables on the market, knowing which ones truly deliver on their promises can be challenging. That’s where the BLE caberQU comes in, a great USB-C cable tester that provide all the details one would need.

We can break down the need to test USB-C cables into five categories; and it’s worth noting if you are going to spend good money on a device, monitor or other peripheral, isn’t it worth a bit effort to make sure the cable connecting it all works at the highest level?

Of course the block buster category is USB-C Data Transfer Speed. Different USB-C cables support different data transfer rates. For example, some cables are USB 2.0 (480 Mbps), while others may support USB 3.1 or USB 3.2 (up to 10 or 20 Gbps). Testing ensures you’re getting the expected performance, especially when transferring large files or using external storage devices.

The BLE caberQU excels in its core functions. It provides a reliable way to test USB-C cables for data speed, charging power, and overall health. The LED indicators offer a clear and immediate visual representation of pin connectivity, which simplifies the testing process. The LCD screen takes things further, delivering detailed metrics on data speed of the cable being tested.

The second most important category is Compatibility. Not all USB-C cables are created equally. Some might not be compatible with high-speed protocols like Thunderbolt 3 or 4, which can impact both data transfer rates and compatibility with devices like monitors or docks. The BLE caberQU provides a systematic way to determine the true connectivity protocol of the cable. Although some cables may give false positive results, it is recommended to test the cable multiple times for Compatibility to insure the BLE caberQU reports the correct value.

Maximum Single File Size for FAT32 Format File System

Maximum Single File Size for FAT32 Format File System

The maximum file size for a single file on a FAT32 file system is not exactly 4 GB, but rather slightly less than that. FAT32 uses a 32-bit file allocation table, which means it can theoretically support file sizes up to 4,294,967,295 bytes (which is 4 GB minus 1 byte).

However, in practical terms, the maximum file size is usually constrained by the operating system or the software used to create or manipulate the file. Some operating systems or software may impose additional limitations, such as a maximum file size of 2 GB or 4 GB.

Furthermore, while FAT32 technically supports file sizes up to 4 GB minus 1 byte, it may not be the most efficient or reliable choice for handling very large files due to its limitations. For handling larger files, other file systems like NTFS (New Technology File System) or exFAT (Extended File Allocation Table) are typically more suitable.

Microsoft did not explicitly stop supporting FAT32 for formatting 64GB drives, but rather the limitations of the FAT32 file system itself led to practical considerations. FAT32 has inherent limitations in terms of maximum volume size and file size.

FAT32 has a maximum volume size limit of 32 GB when formatting drives in Windows. While there are ways to format larger drives with FAT32 (e.g., using third-party utilities or command-line tools), it’s not officially supported by Windows due to compatibility and stability concerns.

Given the limitations, Microsoft and other operating system developers have shifted towards file systems like NTFS (New Technology File System) and exFAT (Extended File Allocation Table) for handling larger drives and files. NTFS, in particular, provides better performance, security features, and support for larger volumes and files compared to FAT32.

Therefore, while FAT32 remains useful for smaller drives and compatibility with older systems and devices, its limitations make it less suitable for modern storage solutions, especially when dealing with larger capacities like 64GB or more.

Why do I have to Eject my USB Flash Drive?

Why do I have to Eject my USB Flash Drive

Do I have to eject my USB flash drive?

The short answer: No.

The technical answer: Yes.

If the technical answer is yes, the why do I have to Eject my USB Flash Drive?

The difference boils down to the type of file system being used. If the USB is FAT, FAT32 or exFAT you do NOT need to eject the USB flash drive before pulling it out of a computer.

If the USB drive is NTFS, then yes, eject the flash drive before pulling it out of the computer.

So why eject when the USB flash drive is formatted as NTFS?

The NTFS (New Technology File System) is a journaling file system system.

A journaling file system is one that keeps track of changes which have not yet been committed to the main part of the file system by recording the goal of such changes in a data structure known as a “journal,” which is typically a circular log. In the event of a system crash or power outage, such file systems can be restored more quickly and with a lower risk of corruption.

Depending on how it is implemented, a journaling file system may only keep track of stored metadata, resulting in improved performance at the expense of increased data corruption risk. A journaling file system, on the other hand, may track both stored data and related metadata, with some implementations allowing for user-selectable behavior in this regard.

With an NTFS formatted flash drive it is very possible there are journal entries going on in the background which the user is not away of, so if the drive is unexpectedly pulled out of the computer that physical action could corrupt the data on the drive.

Why do people format flash drives as NTFS?

Two common reasons people (wrongfully) format a flash drive as NTFS include:

  1. The user would like to take advantage of security settings which NTFS does offer
  2. The user has large single files and isn’t aware exFAT solves the same problem

NTFS allows an Administrator to assign privileges’ to files and folders and those security settings will remain for said files on the NTFS formatted flash drive. This is probably the ONLY legitimate reason a flash drive should be formatted as NTFS.

FAT and FAT32 have a single file limit of 4GBs so any single file larger than 4GBs will not be copied to a FAT or FAT32 flash drive. To get around this problem, Users will format the drive as NTFS. They select NTFS because it’s the same file system as their host computer… and since it works there… might as well format the flash drive the same way. However, what the users don’t understand is exFAT solves the same problem while at the same time providing a more stable file system – one that isn’t a journaling file system – so a flash drive can be pulled out without ejecting.

What replaces write protect switch on USB flash drive?

physical write protect switch, USB

A “write protect switch” for a USB drive is meant to turn on and off the ability to write data to the drive. When the USB is locked (read-only) content cannot be added, changed, altered, manipulated, formatted or deleted off the drive. What is the point of a physical write protect switch if anyone can turn the write protection on or off? Doesn’t add up…

Yes, a write protect switch keeps the honest people honest, however the USB write protect switch doesn’t apply in all situations.

So what replaces a write protect switch for a USB flash drive?

How about programmable firmware for turning ON and OFF the USB write protection?

Better yet, how about a required password before turning ON and OFF the USB write protection?

We can relax because the Lock License USB flash drive addresses both these issues of
#1) Replacing the USB write protect switch with a more secure method
#2)
Provides the feature of assigning a password to turn on and off the USB write protection.

The Lock License drive is a hardware based ( at the chip level ) write protection solution and through a specific vendor software command the write protection can be removed to make the USB stick writable. The function to write protect the media can be done through a provided GUI software application, can use a command line to change the write protect status, or use the command line to build your own custom method for how the USB write protection can work.

The write protection is configured on the USB controller of the flash drive. This means the write protection is done at the device level and will follow the USB stick. The result is a Lock License drive which is truly read-only when connected to anything… such as a Windows computer, Mac computer, Linux box, Smart TV, car stereo, anything!

The Lock License drive comes with a software method to unlock the drive and make it writable. This special software requires a password to be assigned for the unlocking. The password is required because the manufacturer, Nexcopy, didn’t want a universal way to unlock the drive.

Kanguru manufactures a USB flash drive with a physical write protect switch. The write protection itself is as secure as the Lock License solution, the difference is a Lock License drive adds one additional layer of security. The additional layer of security, the password requirement to make the stick ‘writable’ is an important step for ensuring the device is as secure as possible. To be clear, the Lock License drive is always readable. This product seems a great solution for those who want a USB write protected without the ability for users to turn the write protection off with a flip of a switch.

Another interesting fact about the Lock License drive is the default state of the USB stick being read-only, or write protected. This means it is impossible for a user to accidently leave the Lock License drive unlocked.

The “locking” or write protection is done when power is cut from the device. Even if a user forgets to lock the drive, the locking happens automatically when the USB is disconnected from the computer. This is a major issue with those using a USB write protect switch; if a user forgets to set the write protect switch, well not much security at that point.

It is worth noting there is no universal way to write protect any flash drive, this is why you cannot buy some software solution to do the feature. Write protection is a hardware based solution, not software.

From our on-line research, the Lock License drive is manufactured by Nexcopy Inc who is based out of Southern California. The product is available in USB 2.0 for the smaller 2GB and 4GB and any GB capacity higher (8GB and above) is USB 3.0 technology. The maximum size as of this posting is 256GB media.

Ten Questions & Answers About Disk Signature Collision

Below are a list of the ten most common questions about a disk signature collision along with the related answer. The bottom of this article includes a video for some of the diskpart steps, which is needed when investigating a disk signature collision.

  1. What is a disk signature collision?
  2. Why does Windows create a disk signature collision?
  3. How do I find the disk signature ID?
  4. Does Windows 10 have diskpart?
  5. How do I start or launch diskpart?
  6. How to change a disk signature?
  7. Is there a disk signature collision for every device?
  8. What is MBR verse GPT
  9. What is the difference between an online and offline device, how do I fix it?
  10. Where can I find the full list of diskpart commands?
  11. Jump right to the demonstration video at bottom of article

#1 – What is a disk signature collision?

When two (or more) storage devices have the same hexadecimal value for their disk ID (also known as disk signature). Windows does not like to see multiple storage devices with the same signature, so it will take all but one offline so the user gains access to only one device. The signature collision is most often found when binary copies of a master have been made to target devices.

#2 – Why does Windows create a disk signature collision?

Our understanding of why Microsoft did this was to prevent malware from spoofing the OS by presenting an identical seeming drive with bad intent. Bear in mind this MBR stuff was developed when dinosaurs still ruled the earth. Malware was but a dream in some teenage miscreants mind. So little effort was expended in that direction, much to the chagrin of todays Microsoft. The bible says something about this, “The sins of a father shall be visited upon their sons” or words to that effect.

#3 – How do I find the disk signature ID?

What is USB4?

USB4 connector, close up

One-sentence summary; What is USB4

USB4 is the USB-C form factor for connecting; fully supports Thunderbolt 3 specification, all wrapped up using the USB 3.2 specification.

USB4 has four benefits over prior versions of USB.

Maximum Speed of 40Gbps. Using two-lane cables or a set of cables, devices may operate at up to 40 Gbps, the same speed as Thunderbolt 3. Keep in mind there is a big difference between Mb and MB. Mb is megabits, not Megabytes (MB). So for example 8Mb is about 1MB of data. As a reference, a typical MP3 audio file is about 3MB (megabytes). 5,000 MB/second is the theoretical maximum speed of USB4.

USB 4 supports DisplayPort 2.0. DisplayPort 2.0 cables feature 80Gbps bandwidth, making it possible to display ultra-high resolutions at previously impossible refresh rates. DisplayPort 2.0 can handle up to two 4K screens at 144Hz simultaneously, or an 8K display at up to 85Hz natively, with no form of image compression. This is true because USB4 uses all eight data lanes at once time.

Compatible with Thunderbolt 3 devices. USB4 is a protocol which supports all the specifications of Thunderbolt 3; however, Thunderbolt 3 is capable of 100Watts of bi-directional power delivery and not all manufacturers who support USB4 will not include the [full] power implementation of Thunderbolt 3.

Most efficient resource allocation scheme. USB4 devices use a process called “protocol tunneling” which optimizes the use of DisplayPort, PCIe and USB packets at the same time while allocating bandwidth to optimize efficiency. This scheme will create better performance across multiple devices with a collection of protocols.

USB4 will only operate through a USB-C type physical connector. USB4 peripherals will most likely not see older standard USB type A ports because the connection speeds and power delivery mechanisms will not be available. Although USB4 is 100% backward compatible with all other USB protocols, it doesn’t mean the older standard will get the improved benefits. If connecting, for example, a Type-A, 5 Gbps USB 3 port by using an adapter, the speed and power will drop to the lowest common denominator.

Some notable comments:

Device and host manufacturers will not [be required] to pay Intel royalties when implementing USB4 technology. This implies a better chance of mass adoption of USB4; however, there is a catch between manufacturing USB4 devices and making said products [fully] USB4 compliant. Specifically, the Thunderbolt compatibility specification may become a part of the product when developing and manufacturing a USB4 product which can use the USB4 logo. This issue means a consumer could buy a laptop with USB4 and find that it doesn’t work with a Thunderbolt 3 peripheral.

It is important to know Thunderbolt 3 and Thunderbolt 4 are logo certified programs from Intel which cost manufacturers time and money. So, while a USB4 powered computer could work with 40 Gbps devices or even those labeled as Thunderbolt, it may not be obvious because the product didn’t go through a certification process. Or the opposite of this would be a USB4 device does not support Thunderbolt because of the expense required to get the certificate.

USB4 has two speeds. As with Thunderbolt the paradox a USB4 product may not support the full 40Gbps specification. 40Gbps is the theoretical maximum speed, but many devices will use the lower 20Gbps standard because the manufacturing cost will be lower, thus creating a lower target price for consumers. If speed is the number one priority be sure and check the specifications of the USB4 product before purchase. At the time of this writing most USB4 products which support 40Gbps are cables and PCIe adapter cards.

Why the USB4 name?

An online article that summarized an interview with Brad Saunders the CEO of the USB Implementers Forum [USB.org or USB-IF] indicated the lack of space between “USB” and “4” is to focus away from USB version numbers and focus more on brand. This branding concept for USB is a good change, but afraid the history of all the USB versions of the past will continue to haunt them.
