The Fastest USB Flash Drives are SSD

What is the fastest USB flash drive? The fastest USB flash drives are SSD or Solid State. Assuming your Computer is at least USB 3.0 capable, flash drives that are Solid State (SSD) are much more pleasant to work with than NAND based drives. This is due to their greatly increased read and write speeds (often up to ten times faster). They also tend to last longer and be much more reliable. This is because they are not affected by the reduced write limitations imposed on NAND cells. So theoretically, it is possible to run an uncompressed full Operating System from SSD memory, without the fear of premature failure.

My background using fast USB flash drives

Over the past 17 years, I have had the opportunity to work with, use and speed test hundreds of portable external USB devices; commonly referred to as UFD, flash drives, pen drives, thumb drives and memory sticks. I have come to the conclusion that some work great as bootable USB drives, while others do not.

So, in an effort to help others avoid purchasing slow flash drives, I am sharing my experience by outlining my top pick of high quality fast solid state flash drives. Also included are recommended NVMe SSD drives for those who want to utilize the fastest throughput a usb 3.2 port can offer.

What are some of the fastest USB flash drives?

Let me start with one of the most reliable fastest USB flash drive I have used to date.

#1 SanDisk Extreme Pro SSD

1st place: The SanDisk Extreme Pro – One of the fastest USB flash drives.
SanDisk (now owned by Western Digital), has always offered some of the best, fastest, and most reliable flash drives money can buy. Providing up to 420 MB per second read speeds, and 380+ MB per second write speeds, the SanDisk Extreme Pro SSD is an exceptional drive. Covering both speed and reliability, this is my 1st choice. I have used mine for several years to test hundreds of portable installs, without failure.

Instead of using a eMMC – NAND controller, this device actually uses an SSD controller over a SCSI to USB bridge. Making it essentially a Solid State Flash Drive.

How Fast is the SanDisk Extreme Pro?

The SanDisk Extreme pro is pretty fast. Here is a typical real world Benchmark Speed test result for the SanDisk SDC-Z880 256GB flash drive. Performed on a Lenovo Laptop with the device connected to an Anker 4 port USB 3.0 Hub. All things considered, the actual real world performance is not too bad. It is definitely one of the fastest USB flash drives I have personally tested.

NOTE: The actual benchmark Write speeds during this test were 387 – 389 MB/s, but the leading 3 was pushed off when I shrunk the width of the CrystalDiskMark window to take a screenshot.

I think the reliability and consistent speed of the SanDisk Extreme Pro drive comes from how well it dissipates heat while under a heavy use. Its housing seems to work like a heat sink.

Important: The 1TB model is configured from the factory to be detected by Windows as a fixed “Local Disk”. This will NOT work with all software used to make USB bootable. For example, if the USB boot creator tool only display flash drives detected as removable “USB drives”. Though the smaller capacity models are properly detected. Though it should work fine with USB boot tools like YUMI or Ventoy which allow you to select removable and fixed USB hard disks.

#2 Speedy+ SSD flash drive

Boasting up to 600 MB/s read and 500 MB/s write speeds, the Speedy+ SSD flash drive offered by Axe memory is a newcomer to this list. Speedy+ performance metrics shine when used in conjunction with the latest 3.2 Gen2 USB standard (even hanging with some top NVME SSD performers). This device utilizes USB 3.2 Gen2 UASP SuperSpeed+

UASP stands for USB Attached SCSI Protocol. While SuperSpeed+ transfer modes can provide throughput data rates up to 10 Gbit/s.

The Speedy+ USB 3.2 Gen2 UASP SuperSpeed+ flash drive is often on sale, making it one of the best values of the list. While it remains on sale, this is currently my pick of the fastest USB flash drive at the best value. So I’ve moved it to second place.

#3 Vansuny SSD USB Flash Drive

3rd place: The Vansuny USB C – another budget friendly fast USB flash drive
The Vansuny is another budget friendly fast solid state flash drive I’ve been testing and using lately. And so far, it seems to be working well. It provides read and write speeds up to 400 Mb/s.

If you are looking for a USB 3.1 compatible SSD flash drive that is fast, yet inexpensive (sometimes available at almost half the cost of an equivalent SanDisk). This might be your best bet for a fast USB flash drive on a tight budget.

How Fast is the Vansuny Solid State flash drive?

Here are some benchmark test results for the Vansuny flash drive. Testing was performed on the same Laptop as the others. Coming in a smidge slower than the SanDisk, this Solid State flash drive performs much better than most found in local department stores. And makes this list as one of the fastest USB flash drives you can buy on a budget.

#4 SSK SSD USB flash drive

4th place: The SSK USB 3.2 flash drive
Boasting speeds up to 550MB/s read and 520MB/s write, the SSK is another very fast option. Again approaching NVME speed, in some cases, this is perhaps the fastest of all the flash drives reviewed here. This drive utilizes a standard USB connector, however it includes a USB type C adapter and can really perform at USB 3.2 standards, making it my choice for the fastest USB 3.2 flash drive. If you’re asking just how fast is USB 3.2 flash drive? Well, this example is about as fast as they get.

#4 Fanxiang F395 3.2 Dual Type-C SSD USB

If speed is the primary goal (surpassed only by the SSK in some tests), the Fanxiang F395 is one of the fastest recommendations (if you can find it in stock). This dual Type-C USB 3.2 gen 1 solid state flash drive can provide read speeds of up to 550MB/s, and write speeds up to 500MB/s. Bringing forth performance that nears that of a M.2 NVME SSD drive being used in external USB enclosure. Though we have yet to see how it will stand the test of time, short term it has definitely proven to be among the best of performers in this bunch.

Note: You could also use an NVMe SSD drive in an external USB enclosure which can be even faster than the fastest usb 3.2 flash drive or fastest usb-c flash drive. These end up being limited only by the throughput of the USB port. Here is a fast NVMe SSD that I currently recommend.

SSK NVME SSD up to 1050MB/s 10Gb/s

The SSK 1TB external SSD boasts NVMe solid state performance with up to 1050MB/s read and up to 1000MB/s write speeds. It features a built-in 1TB 3D NAND Flash SSD making it the perfect solution for those who need maximum performance and portability. With this device, you can enjoy lightning-fast read and write speeds that are essential for data-intensive tasks. Plus, its 1TB of storage ensures that you have plenty of space to store all of your usb bootable operating systems and data. Whether you’re a professional or an enthusiast, this device is sure to meet all your speed and portable storage needs.

SSK 1TB External SSD NVMe

These are just a few fast flash drives I have personally used here for development and testing. The SanDisk Extreme Pro Series USB drives have historically been my go to first choice. Those memory sticks are phenomenally fast for a thumb drive. However, that Speedy+ SSD flash drive is currently the best value and provides better performance. It might just become my new favorite fastest flash drive for 2023.

They also provide plenty of storage space for Linux distributions, Windows to Go, Windows Installers + anything else one might want to store on them.

Though Solid State USB flash drives may not be cheap, they do tend to last longer. As that old saying goes, you typically get what you pay for. Since the fastest USB flash drives are typically Solid State, they aren’t going to be super cheap.
