TRIM Performance: While SSDs offer many benefits, there are some downsides to using flash memory. One of the biggest issues people run into is performance degradation. Over time, an SSD will run out of fresh blocks and will have to write over data the file system has marked as deleted.

Equipped with 3-bit 3D V-NAND; Available in 120GB; 250GB; 500GB and 1TB capacities; Features RAPID mode and TurboWrite technology; Excellent sequential read and write speeds under most conditions; Good random read performance; Performs equally well with compressible and incompressible data; Good...

Mediocre random write performance; RAPID mode is Windows only

Faster, significantly increased longevity and at the same time lower production costs. These three seemingly contradicting aspects are what Samsung are said to have succeeded with 3D V-NAND.

TurboWrite cache accelerates esp; smaller models, Supports Microsoft eDrive (encryption, Very good everyday performance, Five-year warranty

Loss of performance under extreme load

Once again, Samsung delivers a great product, taking the lead in the SSD space with its advanced technology. 3D V-NAND is really a game changer. The 3rd TCL generation offers pretty much everything the consumer would want to see from an SSD, performance, high endurance, encryption, low power...

Since entering the SSD market Samsung have created some very impressive drives. In the early drives, when other manufacturers were struggling for reliability, they were seen as being industry leading on that front.

Samsung has an excellent overall package here, with great features, innovative technologies, performance, and durability.

Slim form factor; Very fast out of the box; Blistering fast with RAPID Mode enabled; Data Migration software; Large capacity

Modest price premium

The M.2 socket first appeared a couple of years ago and the market has been slow to take it up in force. Whether, like Thunderbolt, this is because there is already a huge market for regular devices, or whether storage manufacturers are waiting to see which of the two variants will be the winner -...

After we reviewed the 850 Pro 512GB model and heard that Samsung would also send us the 850 EVO 500GB we thought that there would be a sufficient performance gap between those two to "justify" both the different target areas and the difference in price.

Today we have the latest model from the Samsung SSD 850 Evo on hand, the mouth-watering 2TB model. Previously the 850 Evo range extended to a 1TB model but for those that find that simply wasn't enough, Samsung has doubled the capacity and in the process created what is by far the largest capacity...

When we sampled the previous generation 840 EVO from SAMSUNG we were very impressed. It was reasonably priced, had good encryption qualities and in stock format was also a very fast drive. Add RAPID technology and the drive became a performance beast.

The 2.5" SATA versions of the 850 EVO will be available 'later this month (December)', with M.2 and mSATA versions coming 'next year'. The 840 EVO was a great launch and sold very well, but Samsung did not rest on their laurels.
