Is it worth buying a USB 3.1 Flash Drive?

Is it worth buying a USB 3.1 USB flash drive?

The tech industry, tech nerds and tech blogs will definitely say that buying a USB 3.1 flash drive is worth it. After all, these blogs need something new to write about and new links to generate for affiliate advertising, but are these blogs reporting back valuable information before someone spends their hard earned cash?

Let us compare the write speed difference between a USB 3.1 flash drive and a USB 3.0 flash drive to see what information we can uncover.

Universal Serial Bus (USB) has different transfer speeds based on the version of technology, we did a write about that earlier. The USB 3.1 specification has a transfer rate which taps out at 1,250 MB/second (Megabytes per second). The USB 3.0 specification has a transfer rate which taps out at 625MB/second. Of course this is the theoretical maximum transfer speed. When anyone says “theoretical transfer speed” they are implicating all conditions are ideal. For example, the host computer has the horsepower and bandwidth to push that much data and the receiving device (in this case, flash drive) has equal throughput to receive that data. But is that the real world – is it worth buying a USB 3.1 USB flash drive?

Below are some images and here is the general order of what you will be reading:

  • Screen shots of the USB device type (USB 3.0 and USB 3.1)
  • Screen shots of benchmark software testing both USB technologies
  • Screen shots of a real-world copy jobs using a Windows computer

From the screen shots below you can see a USB 3.0 flash drive and USB 3.1 flash drive. Both flash drives use an SMI controller for the USB 3.0 and 3.1 technology. These are the same high quality and higher performance controllers seen in iPhones and NAND memory used from Micron Technology. The NAND memory type is MLC (multi-layer cell memory) is slower than SLC NAND memory (single layer cell). Note: USB flash drives do not use SLC memory because the NAND memory price is too expensive and the SLC supply is very small. Flash drives are produced at mass scale and meant to be a low cost data transfer and storage tools – speed is not the #1 priority, despit all the marketing we read online.

Here are benchmark speed tests for both USB devices in discussion today.

The program has two test settings for benchmarking a speed test. One test setting is for the theoretical maximum speed of the device and writes data directly to memory without accounting for operating system and device overhead for were the data is stored. Think of this as a random write test to any available sector on the flash drive.

The second test setting is a write sequence which includes the operating system and device overhead cache for placing files in the file allocation table. This means extra time is spend during the data transfer to log where each sector is written along with the calculation required to write the next bit of data. This second test setting is more like a real-world experience.

Speed benchmark software is designed to provide a relatively quick summary of the device capability. So the first test setting is designed to show the theoretical maximum write speed or “burst” write speed. The second test setting is designed to show a more “sustained” write speed. Any benchmark software is designed to provide a quick and easy snap-shot of what the device can do – but can the device do it?

Readers can download the USB Scrub software for speed benchmarking their flash drives. The software is 100% free, no installation or sign-ups, and includes other cool features like registry cleaning and making image files of flash drives. USB Scrub download link

Micron Commits $15 Billion for New Boise Idaho NAND Factory

Micron Memory, a leader in worldwide supply of semiconductors, committed 15 billion dollars for the new construction of a manufacturing plant in Boise Idaho.

This new plant will be the first built in over 20 years inside the United States. In addition, it will become the only operational manufacturing facility within the United States. The 15 billion dollar investment by Micron will span the next ten years with investments inside of Boise and in other states as well.

This is the first of several planned US investments by Micron following the passage of the CHIPS and Science Act. This is the largest private investment ever made in Idaho. The new manufacturing fabrication facility will be a co-location with Micron’s Research and Development (R&D) center. Being this close to the company’s headquarters will improve operational efficiency, accelerate technology deployment, and shorten time to market.

The CHIPS and Science Act is a federal law in the United States that was passed by the 117th United States Congress and signed into law by President Joe Biden on August 9, 2022. The act includes billions of dollars in new funding to boost domestic semiconductor research and manufacturing in the United States. The law is divided into three sections, each with its own short title:

  • Division A is the CHIPS Act of 2022
  • Division B is the Research and Development, Competition, and Innovation Act
  • Division C is the Supreme Court Security Funding Act of 2022.

This endeavor will generate an estimated 17,000 new American jobs in which 2,000 will be Micron direct hires. To support Micron’s growing employee population, the company plans to open a world-class childcare facility operated by our local partners at the Treasure Valley Family YMCA across from Micron’s corporate headquarters. The center will provide STEM-based programming and easy access for parents to interact with their children during the day, as well as ease the transition for those, particularly mothers, returning to the workforce.

Boise State University, which is located less than ten minutes from Micron’s headquarters, is ranked 131 in Engineering. The press release from Micron did not mention investments or support to improve the engineering school’s rank over course of the 15 billion dollar investment. The #1 engineering school in the United States continues to be MIT (Massachusetts Institute in Technology).
