Special note for Surface Pro 3 users: The Surface Pro 3 does *not* have adequate power to drive this external SSD by default (Purposefully designed to get longer battery life :|). You will need an external 'USB Y cable' compatible with USB 3.0. Plug the SS (super speed end) into the Surface Pro 3 and the other into the USB port available on the power adapter and you should be good. Occasionally the SSD driver might reload causing other drivers (such as Bluetooth) to malfunction, you might have to reboot the SP3 to get this corrected. Lookout for UASPStor messages in the event log to troubleshoot the issue. Also set the USB and Hard disk settings in advanced power options to 'Never'
It might also look like the cable is heavier than the SSD itself :-)
In summary, this drive was totally unreliable in my experience and resulted in total data loss.
Amazon sent a replacement overnight. The new drive has the exact same problem. I still can't believe it won't even connect on the Mac or Surface!
Windows will see the drive as dirty but show no errors after checking. The partially copied file is of course corrupted.
I am using on USB3 ports on a Lenovo X230 CoreI7 running fully patched win 8.1. I have tried various usb port settings and windows file settings and the problem still persists occasionally. Maybe my unit is a lemon. File retention hasn't failed but I don't have the highest confidence in this drive due to my particular experiences. YMMV.
After flashing latest firmware I have had no further problems with this product. Still going strong until Jan 11, 2017
I would definitely recommend this to anybody looking for a decent flash drive unit.
I tried to download the driver from the company's website but Norton Security keeps rejecting and deleting the zip file; not sure if it's Norton or Windows 8.1.
In any event, great value for my money, if it actually works and it would be even better if it works on Windows and Mac OS -- I'm hoping to get a new Mac later after Apple updates its MBP 15".
Update: March 2016
Thank goodness this external SSD actually worked; I backed up the content from my 13 plus year old Sony Vaio laptop, which had Vista OS when I first bought it, before my beloved Vaio died -- coincidentally on the same day of Windows 10 official release in the US. I was able to transfer the content from this external SSD to my new laptop -- HP 360 Spectre -- which I bought last June from a Microsoft store. I'm giving this SSD a 4 star because the user interface was not that friendly to someone like me -- a non-computer person.
