SanDiskExtreme PRO Solid State Flash Drive 256GB (USB 3.2 memory stick up to 420 MB/s read speeds, up to 380 MB/s write, Password protection, RescuePRO data recovery software, durable casing) Black

Perfect for large files (e.g. MP4 video files), sustains high transfer rate, and seems long term reliable. Better than all my other USB memory sticks.

Fantastic speed

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 seconds2. There is free 1 year software included which helps recover accidental deleted files and much more3. Password protection can be set up to encrypt specific files or folders you want4. Sliding mechanism which is really convenient and smooth; it also protects the metal partImprovements:• 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 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.

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.

I always love using sandisk products they are reliable and gives u long term and always good to use and storage capacity is good too and money wise its ok so i have no complaints and must to try this brand and their products

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!

I ordered 2 of these one worked fine the other didn't work at all and the seller would not take it back or replace it or refund me.. Do not wast your money on buying this product as the seller is very unhelpful and the product has a 50/50 chance of being faulty.
