The best memory sticks you can buy

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!

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)

Compact high capacity memory stick, positive fit in USB socket. Transfer rates seem good but I haven't loaded it to the max yet. Fair value.

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.
