Will this SSD have enough space for me?
This Samsung 850 EVO is the world’s first 2TB solid state drive (SSD) for client PCs. It is powered by 3D V-NAND technology to give you faster data access times, program load times and multitasking abilities – increasing overall speed for higher productivity. This SSD has sequential read and write speeds of up to 540MB/s and 520 MB/s respectively. It is also capable of achieving random read and write speeds of up to 98,000 IOPS and 90,000 IOPS. These speeds are obtainable due to the TurboWrite technology and you can enhance speeds even further by enabling RAPID mode within the included Samsung Magician software – which creates cache storage with unused PC memory (DRAM).

How good is this SSD for laptop use?
The 3D V-NAND technology implemented into this SSD, makes it highly energy efficient. This helps to increase the battery life on your laptop or Ultrabook, as it also supports device sleep mode in Ultrabooks.

Is my data safe within this SSD?
The 850 EVO uses AES 256-bit encryption technology to give a hardware-based full disk encryption engine and ensures you data is secure. This means that your data will be protected, while you lose no performance compared to software based encryption technology. Dynamic thermal guard technology is also incorporated into this SSD. This technology monitors and maintains the optimal temperature of the SSD and automatically lowers it – minimising the risk of overheating and protecting your data. What’s more, the endurance of this SSD is measured at up to 150 total byes written (TBW), with the warranty of this SSD covering it for up to five years or 150TBW, whichever comes first.

What software is included with this SSD?
Supplied with this SSD is Samsung’s Data Migration software, which lets you copy all of your data and applications from your existing SSD or hard drive disk (HDD) to the 840 EVO quickly and easily. Also included is Samsung’s Magician software – which you can use to setup, monitor, manage and maintain your SSD, optimising the SSD for your system and needs.

How will a V-NAND drive help me?
V-NAND technology is a step above other SSDs. Instead of making the cells smaller to squeeze more in, it stacks them on top of each other. Silicon nitride layers also aid in preventing corruption caused by cell to cell interference, providing up to twice the average life span of other SSDs.
V-NAND technology not only lasts longer, but it uses up to 45% less power and delivers writing speeds of up to two times faster.

Rated 5 out of 5 by from Really good SSD and useful software (online!) Bought this to replace an old Crucial M4 256GB SSD in my PC. Comes with migration software on CD but you'd be better off downloading it from the Samsung site as I couldn't get my CD to load. That aside, copied the OS (Win7) perfectly, with correct sector alignment, the new SSD installed flawlessly and it's worked perfectly ever since, so the migration software and actual produce is very good. You will need either a spare SATA connection or (as I used) an external USB to SATA adaptor. Thinking of buying another for my wife's laptop.

Rated 5 out of 5 by from Superb upgrade even for old(ish) laptops Just to add to my previous review of the 1TB version, I was so impressed at this SSD's performance in my desktop machine that bought the 500GB version for my wife's laptop. I had tried to clone another brand of SSD with no success - but the EVO850 plus Samsung's migration software is flawless. The new SSD worked first time, and in addition, it preserved Samsung's recovery partitions too. After installing the new SSD, run the Samsung Magician software which allows you to set the SSD for max performance or max durability - I chose the latter. The laptop is an i5 SF-310 which has only SATA2 internal ports but it was still well worth while, and has hugely speeded up this old(ish) but still excellent laptop. If you look around you'll see lots of positive reviews for these SSDs and I can see why.

Rated 4 out of 5 by from Good Drive- Shop price within a few pounds of mail order so more than reasonable. I actually bought the wrong format, Should have got m.2 but the drive itself is fine and without issue.

Will this be compatible for upgrading a stock ps4 hardrive? If yes how would it fare in terms of storage and speed?

Asked by: Gman
This should work fine in a PS4, storage will be the same as any other 1TB drive, it would depend on the size of games and files you are storing on it. You may see a speed increase in some areas, however the PS4 may have load limiting due to the requirements for multiple functions to run at the same time.
