o extended sequential write performance, by allowing more parallelization of the writes for large files once the buffer fills up. TLC nand in 2d form used to slow way down to 120~160mb/s (almost hard drive speeds!) in the first few generations, but this 3d TLC is really fast stuff. This drive is rated for good levels of endurance, and you shouldn't use it up in under a few years without running a server.Tried transferring some files off the RAID array (which can read faster than this drive) - Started at about 550mb/s and dropped to 495~508mb/s by the end of a 20.x GB transfer of random ZIP files of 300mb to 2.x GB in size while the drive was fresh and new, for a good accurate test.GREAT performance on an intel Z97 / 4xxx series computer I built a few years ago.Has GREAT random 4k performance IOPS too (this is what you'll use when you boot Windows and open many complex programs)I am truly impressed by this drive. The data reads after a month or more haven't slowed down at all. I never bought a TLC-nand drive before, but this 3d TLC nand is really something. If you're an MLC-only kind of guy, and can't quite afford a Samsung 960 Pro NVME drive (or similar), pick this up to hold you over, you might just not care enough to upgrade it after that. It's quite snappy - totally shocked here.So I found my new go-to for cheap data storage in a machine with about 7-8 SSD's in it, mostly Toshiba drives, if you need to add some storage or want a large boot drive for a new PC, this thing is great. It has pretty good endurance, too, you would be hard pressed to wear it out unless you ran a server, so no worries.For the Techies:The speeds on the 1TB model are EVEN BETTER than the 500gb model (though not by too much noticeably to the user), so I am really shocked.Get the 1TB model if you can afford it. If you just browse the net and don't play many or any games, the 500gb or 256gb model may do just fine.It's random 4k perf ties/beats my SSD RAID array on the motherboard and the SSD RAID Array on the LSI Megaraid server card, but to be honest, RAID arrays of SSD's while enhancing sequential speeds, don't boost up 4k performance much any, just so you know.RAID= Redundant Array of Inexpensive Disks - these give you reading&writing your data fault tolerance, or more speed, or both, mostly they're for servers or high-end home computers and work-stations.I do content creation, so I need data-redundancy here, and for that, and occasional large file editing on 3d terrain creation, this drive fits the bill!Will be getting more of these guys. Can't recommend enough - same with all the tech-site reviewers.

ce (hard drive clunking and thumping are gone), #2 Windows 10 boots faster, #3 Some applications like Quicken 2017 & Excel seem quicker to load (but didn't measure so may be my imagination), and #4 My daily Acronis backup (in the background) of my entire computer to a network drive only took about 1 hour versus 5 hours before (didn't expect this and can't explain it). I had expected a couple C# applications that load huge files taking 13 seconds and 17 seconds to load with my old old drive to load faster with the MX500 SSD but they did not (again I can't explain this). Would buy this drive again!!!
