New and Snappy Product from an Old, Reliable Lineage
Reviewed in the United States on January 28, 2018
Already converted the 2.5-inch drive in my HP Envy 17 to a Samsung 850 EVO 1TB drive and saw the M.2 slot and thought it would be interesting to try something new. Then Amazon brought out the 860 EVO M.2 500gb ssd and I just couldn't resist. I have to say immediately that the installation hardware-wise is just like all the M.2 installs on YouTube, etc. Plug in at 30-degree angle with the five-contact side of the drive on the right with the sticker side up. Didn't come with a mounting screw, but I ordered a box with some in it (M2x3 with 4mm-4.5mm head I have been told.) M2x3 with
4.5mm and it was installed. Cloning didn't work for me because of the large drive to smaller drive issue -- which left me with the regular SSD as boot and the M.2 as second drive. Since my laptop is brand new and doesn't have much personal stuff on it yet, I just decided to get a Recovery Drive USB key from HP and reload it. On a hunch I carefully uninstalled the regular SSD, leaving the M.2 as only drive. Ran the Recovery drive and the M.2 was recognized and loaded just fine (although took forever to get all the updates installed.) Read HP forum and watch YouTube reference all the installation iterations. The 860 EVO this review is about ran smooth as silk from the beginning appears to average about 540-550 read down and about 490-505 write (seq), compared to about 520 read and 490 write on the regular SSD above. I did try out the Samsung Magician software (a caching program using M.2 and system memory to speed things up) and that showed about 4700-5000 read and 4000 write. Seemed snappier to me, but read all the pros and cons on line because everyone doesn't agree on how good it is. Bottom line -- the 860 EVO M.2 is a brand new successor to a tried and tried product (850 EVO M.2) and I think it shows. I expect to have good service and modestly better performance. At this point I would recommend any of the 850-860 line SSD or M.2 drives to a friend.
