SanDisk Extreme PRO® USB – ‘Fastest USB I’ve ever owned’

Am no expert USB ‘Techie‘ but I do know what ‘Desktop Duty‘ is — it is the performance I expect from ‘My Computers‘, other hardware, my OS, and other software (to a lesser degree).

When I transfer a 4.46 GB Redcore.Linux.Hardened.2301.Sirius.KDE.amd64.iso from a download folder to a 128 GB USB (NTFS format), I don’t like waiting for 2-3 minutes – or more in some cases. Here’s an example of the different Write speeds between a 128 GB SanDisk Ultra and a 128 GB SanDisk Extreme PRO®:

The Ultra took 118 seconds. The Extreme Pro took 14 seconds. Write speeds are more important for me than Read speeds – What are USB Read and Write speeds?:

Speed is a critical factor when choosing computer hardware, and Flash Drives are no different. Put simply, a ‘Read speed’ is how long it takes to open a file from your Flash Drive. A ‘Write speed’ is how long it takes to save something to that same Flash Drive.

Here are some more examples of the speed differences in USBs, using CrystalDiskMark8 benchmark software…

I test a lot of Linux Distros, and a faster Write speed will help me in those tests – gotta love my new SanDisk Extreme PRO®!!! 😁👍👏👌

The ‘SanDisk 128GB Extreme Pro USB 3.2 Gen 1 Solid State Flash Drive, Speed up to 420MB/s (SDCZ880-128G-G46)‘ cost me $39.99 from Newegg – wid $2.80 in Tax ‘n Free shipping it was $42.79 total. Expensive, but if Write speed is important to you then the price is well worth it, IMHO.

I have over 30 different USBs that will no longer be transferring large files — what else can I say!?! 😊

Well, I do use a 500 GB SanDisk Extreme Portable SSD V2 for backing up my main Data, and a 500 GB Samsung Portable SSD T7 as a second backup device (backing up backups), but they are not ‘Desktop Duty‘ USBs. 😉
