Awesome and fast drive
Great for making a portable SSD instead of paying just as much for a slower USB 3.0 or 3.1 flash drive. Maintains read and write speeds of 300mB/s + Will update on longevity of drive and how well it holds up to constant use and being carried around in a backpack every day (inside a SATA M.2 USB C enclosure though) Edit: 11/07/2018 Drive still holding up extremely well. I've probably transferred over 4tb of data across this drive and leave it plugged in most of the time to watch movies and TV shows off of that are loaded to it. Has yet to glitch on me once, only the m.2 housing that it's in has given me any sort of issue and the seller of that item resolved the issue by sending me another.

Works great. Win 10 boots much faster than using traditional hard drive.

Good device, longer than the one it replaced.
This seems to be a pretty good device. I am pretty technically competent, but not a lot of experience with M.2 devices. I had a 64 g SanDisk fail on my Dell Venue 11 tablet and read that the 128 would work. A word of caution: not all m.2 SSDs are the same size. This is considerably longer than the 64g device that failed in my tablet. (I know, the size IS listed on the product description) I was able to get it to work by modifying the case a bit (somewhat nerve wracking), but after that it worked like a champ. I assumed that m.2 SATAs would be a standard size like mSATA. Big surprise for me that it was not. Check your device you are replacing and make sure that this will fit. Other than that, seems plenty fast and a good value.

Great buy and great speeds
Great product and caught it on sale, transfer speeds are as described not had a single issue. I used this with an external usb 3.1 kit from Silverstone and could not be happier with it.

Don’t be afraid to buy used :)
Despite being used, the product came in working condition. I had some problems getting it to work but that was user error, always make sure to activate the drive when you get it.

2 full months of use and these drives are already dead. Sandisk has made some great products that I have loved over the years and this isn’t one. Both drives are used up and reading as 0%usefull life. They were used as read only drives and not written to that much. Should have gotten decades not months of use.

Tip top Rennt im NUC 6i3SYK
Tip top Rennt im NUC 6i3SYK. Alles wie erwartet. Was will man mehr. Der SYK ist ja die flache Version wo keine 2,5" Platte rein passt. Daher hab ich die 128gb genommen. Wer die hohe Version mit 2,5" Schacht hat kann sicher auch eine 64gb SSD nehmen.

not a great look. But the product is indeed genuine
Was a bit unhappy to see that the product i received is not what the picture is showing. Green PCB with a white sticker, not a great look. But the product is indeed genuine. No problems so far.

Problemlos, schnell, günstig
Als Bootplatte sehr geeignet. Im Gegensatz zu den anderen 128GB M.2 SATA SSDs, ist diese hier noch recht schnell und bietet 5 Jahre Garantie.

C'est tout petit !
Plus petit qu'une barrette mémoire, tout mince et très facile à installer. Le plus difficile est de repérer sur la carte mère le slot M2. On le glisse et on pose une petite vis. Bien moins contraignant que les Disques durs SSD et leurs câbles Sata fragiles, bien plus rapide, ce petit disque est idéal pour installer un windows et ses maj. Ajouter un autre disque à plus importante capacité pour stocker vos logiciels et le tour est joué. Windows démarre en quelques secondes :) Je recommande vivement ce petit disque dur pour donner un coup de jeune à votre pc. Bien évidemment votre carte mère doit le supporter et posséder un slot M2.
