Bests & Worsts Reviews from Amazon

Very small drive. Read speeds close to advertised. I got sequential reads on the 256GB drive in the low to mid 290s MB/s. I got write speeds just under 60 MB/s (sequential). I'm getting random read and writes between 13 and 15 MB/s. See screen shot from Crystal Disk Mark 6. Write speed was not advertised - specs just say "write speed is lower than read speed". Yeah, less than helpful. I'd prefer to have the write speed advertised so that we can make a more informed purchase. I hope my test helps you all out. At this price point and for a drive so small I'd say this is a decent purchase. You get huge capacity in a small form factor with write speeds that are in the ballpark of the SanDisk Extreme Pro. If you don't need to consistently write large files - this may fit the bill. If you need faster sustained writes, don't mind a larger drive, and have an extra $35 - maybe the SanDisk Extreme Pro is for you.
