SanDisk 128GB Extreme PRO USB 3.2 Solid State Flash Drive, up to 420 MB/s read speeds, up to 380 MB/s write speeds, password protection, RescuePRO data recovery software, durable casing

1. £36 may seem a lot just for a USB but it’s worth it considering 124GB of available storage and the unmatchable speed. I believe this is the fastest USB you can find in the market with the highest reading and writing speeds. I transferred a 4GB file under 10 seconds 2. There is free 1 year software included which helps recover accidental deleted files and much more 3. Password protection can be set up to encrypt specific files or folders you want 4. Sliding mechanism which is really convenient and smooth; it also protects the metal part Improvements: • The price could be a little lower • It’s larger than other USB’s but this shouldn’t be a problem • Durability wise it could’ve been made from stronger materials (still top quality) • It can heat up especially after prolonged use • Apparently the speed goes down over time as well as when more of the USB capacity is used up however I haven’t experienced this myself (shouldn’t be noticeable for a regular user) Final verdict: I definitely recommend it. You won’t find a better product!

I bought 2 fast drives... Sandisk extreme pro usb3.1 128gb. Corsair voyager usb3.1 gtx premium 256gb. I set them up in a test to copy the same 25 movie files from my windows 10 pc. There were 25 files totalling 80gb. Both drives are formatted in NTFS but weren't freshly formatted. There was plenty of space on both drives. The results were quite surprising. The Sandisk drive ran at a constant 100mb/s approx speed for the whole transfer, whereas the Corsair drive ran at about 100mb/s approx speed for the first 5 minutes or so, and then dropped down to between 25mb/s and 30mb/s for the rest of the transfer. The Sandisk did the 80gb in 13m21s whilst the Corsair did the 80gb in 36m44s. These results are quite surprising. It would be worth repeating the tests with both drives being freshly formatted. To sum up, it seems like if you are transferring up to 10gb of data at a time there won't be much difference between both drives, however, if you are transferring much more data, I'd go for the Sandisk. In terms of the feel, the Corsair drive feels great in the hand, but it is large and heavy and quite wide. If you have two usb type A ports next to each other then you may not be able to use the other port if you have the Corsair drive plugged into one of the ports. The Sandisk drive is also a little wide but no where near as wide as the Corsair. The Sandisk drive is slippery to grab when you try and pull it out of a usb slot on a laptop. Also, the angled bit at the back end of the Sandisk drive should have been made the other way round so you could grab the end easier to pull it out . It slopes down the wrong way!

as for value for money - of course you can get more storage for the same money or the same storage for considerably less. but those sticks wont give you these speeds. so that depends if you care for speeds or not. if you dont, there are much better value options out there. but if you do care for speeds... cant say anything about durability - might update in a couple years! i bought my old transcend 8gb stick 10 years ago and i still have and use it. if this one lasts 10 years too, i'll be happy. the slide out mechanism was problematic at first, as the plug wouldnt stay fix in its "out" position. as soon as i pushed it a bit with with my finger, or tried to insert it into a usb port, it would retract. but that has gone away after sliding it in and out a couple times. hope this has settled this now. with 6 years consumer law here in ireland i am not all that concerned though. the speed is really good. sustained write speeds of around 320-330 mb/s and sustained read speeds or around 380-390 mb/s, tested with a 6.3gb mkv movie file. so not exactly as advertised - they say write up to 380 mb/s, and read up to 420 mb/s, but still one of the best out there. and just as an FYI, it does get notably warm after writing/reading for 10+ seconds.

All working fine

I have one computer which is still of the 2009 era so has not really got usb 3 - i added a card but this isn't going to be as fast as the true usb 3 rig. Having said that the speeds are stunning from this. Most of the time what one will find with usb 3 sticks is the read speed is perky but the write speed is usually pretty poor. Not so with this - I have some hard drives that can't keep up with this and that's quite a thing. I also have the same comment from a friend who says pretty much the same thing on his rig which does have usb 3. Faster speeds than I get and competes with the internal HDD. Of course if you look at the cost vs SSD or HDD it's massively expensive but in this day and age we do pay for speed but I bought this in a sale and it was the cheapest I have seen - given that this 128GB was worth it to me and the day after I bought it, the price was 50% more than I paid. I'm glad I jumped at it when I did.

Really like using this as a DJ, It has fast read/write speeds and didn't need formatting for mac (although I would recommend a format when you receive the device just in case! I've used it on CDJ's and all in one devices with no issues. I like the retractable part, this is well made and doesn't feel like it will break which is often an issue with a device with a similar mechanism. I had another one of these, that went through the washing machine, and it worked afterwards (after drying) so should withstand most wear and tear!

Sandisk is a reliable and safe brand for storage devices. £42 for 128GB USB flash drive seems a lot however, this is SSD flash drive so the memory chips have far higher durability then the standard flash drive. This is important if you want to keep documents or files safe from bitrot or normal data degrade over time. 1GB file speed test 560.2 mb/s for write and 377.1 mb/s for read on Macbook Air m2 with Blackmagic disk speed test However, with 5GB file read were 353.5 mb/s and write 214.2 mb/s but reduce speeds over time is common for large file such as this. Design is great with silver aluminium metal casing and a sliding mechanism which protects the USB male port. The drive is great as boot drive for something such as unraid as you don’t use up a hard disk slot. This is the reason why I bought it as I needed a boot drive for my unraid. I used a free USB slot in my dell R730. Highly recommend.

Update.. The reason why I had issues was because the bugs and lack of read support the new APFS file system has as compared to HFS+ AT first I assumed the device was faulty because of this, but reformatting drive gets it working again.. So far now I know it was Apple to blame, the device has been working well as an external OS drive without me having to update the internal drive and loosing function of art software. I thought it would be good idea to clone my High Sierra from a standard USB three stick drive to a SSD one, and got this. It did the job. Reason for this is I refused to update my main Mac drive as I have a mental health issue with flat design, and some of my art programs would stop working ..but my iPhone i keep up to date for financial stuff, I cant synch updated iPhone iOS 11 in Mavericks, iTunes 11 , so I had to install macOS on separate drive to do, but due to usuage speed, it is a bit a pain the arse to do, and as certain things need updating. Cloned the 128GB High Sierra to this 256 SSD USB stick drive. Found os Booted almost as fast as my main drive, which was good enough to create an illusion that it was booting off a partition of internal drive. I decided to update to Mojave , it worked.. but ran a bit slower than High Sierra and after 2 boots, the drive failed, making macbook unbootable while drive was in the port. I thought my Mojave killed my mac. But mac booted when drive was removed. Then i booted into Mavericks, I found the the drive would not register or load in Finder.. tried on my other computers nothing.. Then i opened Disk Utility.. it was reading the drive but the partition was gone, including the restore one for high Sierra for the drive. I thought the drive was busted and even filed a return.. but then I tried erase/reformat drive with a new partition, it became usable again. Cloned High Sierra back on again, and its working again. So I am thinking the problem is on Apple , and would have to hope Apple fixes the partition destroying bug in its new update. (some people experienced this problem occur on their main drives when updating, rendering their macs unusable until repair by a technician)

I already possess a 64GB Sandisk Extreme USB flash drive that is really fast and works extremely well. This 256GB Extreme Pro USB flash drive is just as good (if not slightly better in performance) and one of the fastest USB flash drives in the market today. The only difference is that the Extreme looks a lot cooler with red lettering and has a slightly better connector retraction and deployment mechanism vs the Extreme Pro.
