The Intel 535 SSD was quietly released in April 2015, very few review samples were distributed and the release went largely unnoticed. The 535 sports the same basic specs as its predecessor, the 530. The 20nm NAND in the 530 has been replaced with marginally slower 16nm NAND and both drives use the same five year old SandForce 2281 controller. Comparing performance between 240GB 530 and 535 shows that the two drives share the same performance profile which is severely hampered by a particularly weak incompressible write speed, something the SandForce controller is notorious for. Overall the 240GB 535 scores an effective speed of 71.5% which puts it amongst the slowest handful of new SSDs on the market. There are other drives on the market that use newer technology and represent far value for money. [Aug '15SSDrivePro]
The 250GB Samsung 850 Evo has a similar architecture to its hugely successful predecessor, the 840 Evo. Both drives are TLC based but the 850 uses 3D V-NAND as opposed to regular NAND. Both drives also feature a Turbowrite cache (TWC) which buffers up to 3GB of writes. The TWC enables high burst write speeds but when the cache exhausts write speeds drop to 300 MB/s. Comparing the 850 and 840 Evos shows that effective speed, has improved by 11% and the warranty has been extended from three to five years but prices are also up by 11%. The 850 Evo does put in superb benchmarks (second only to the 850 Pro) but these are only valid within the TWC. At current price levels the 850 Evo struggles to compete with the value leaders.
