Solid reliable SSD drive. I use it to replace an older and smaller, 500GB, Crucial M500 SSD drive. This 850 Pro drive is much faster to boot and run programs.

Degrading performance had me take the step to upgrade the hard drive. Glad I did, faster loading, quicker responses have enabled me to do more work in less time.

Samsung Customer Support will not advance replace a defective drive. Instead, you must ship the defective drive to Samsung, wait for them to test, repair or replace, and return ship. So if you (as I) need reliable, advanced replacement, Samsung is not the company to consider

Makes any PC come to life and boot up 'instantly'. This is very suitable for top range i7 Laptops (or PCs) and works well with fast Vengeange DDR ram. Like turning your PC into a top end Mac Book Pro. Result is top score on Windows performance ranking.

Bought this to replace a Crucial M500 which was hosting a windows 10 VM on my imac. The Crucial disk wasn't giving any problems but I wanted the extra space and what I thought was extended life.

Got two of these a few weeks ago. I have raided them together on my iMac 27" in a thunderbolt enclosure. (StarTech.com S252SMTB3 - Thunderbolt Hard Drive Enclosure with Thunderbolt Cable). I get read speeds over 880mb/s and write speeds averaging around the 850mb/s mark. Amazing drives.

Time will tell, however from past purchases the Samsung's have proven very reliable. This drive comes with system copy software as well as health analysis software.

Installed it in a mid-2012 MBP unibody A1278 with macOS sierra update, 16GB RAM, after the factory HDD crashed. Reinstalled Yosemite on the SSD. EtreCheck went from "very poor" to "excellent". MBP boots up very fast.

Make sure all your drivers & your BIOS are up to date. Make sure you know your passwords & pin numbers, and attempt to delete using them to access the computer in the boot up sequence.

10 year warranty; Magician software; Fast as greased lightning on a wet lawn; Computer boots from a cold start to ready in 14 seconds; Rugged, and less likely to fail due to mechanical problems, as these don't have any moving parts

Maybe the price, but you only cry once with buying the high quality items; If the drive goes bad, you will lose your data, IT'S GONE! There is no putting the disc into another working drive and recovering the data.

The 850 Pro is Samsung's new flagship consumer SSD, and the follow-up to the wildly popular 840 Pro, which was one of the best performing SSDs money could buy when it launched in September 2012. We're reviewing the 512GB model here which is priced at ￡232 (US$399, around AUD$420).
