Evolution according to Linnaeus
The Samsung 970 EVO M.2 is a "reactive" M.2 NVMe SSD that is several times faster than typical 2.5" SATA and M.2-SATA. It is built on Samsung's own 3D TLC memory and a Phoenix controller. The older model 970 PRO M.2 has the same controller, but even faster and more durable 3D MLC memory. Both models come with an extended five-year warranty.
Hot stuff
Linear read and write speeds within a 10-gigabyte SLC array are 3400 and 1500 MB / s, which is three to seven times faster than top-end SATA SSDs. When the array overflows, the read speed does not change, and the write speed drops by a factor of three, which approximately corresponds to the level of a planar MLC memory. Another thing is that PC users rarely operate 10-gig files, so the speed drop due to overflow of the SLC array will practically not happen. But an emergency speed reset due to controller overheating is a typical situation for NVMe SSDs. The problem is solved by a cooling radiator, which are sold both separately and bundled with some motherboards.
Not a second of delay
Even more impressive is the processing speed of the smallest 4K blocks: 350K and 250K IOPS for reading and writing, respectively. The credit for this is not only the fast Samsung memory and the Phoenix controller, but also the DDR4 cache RAM (instead of the low-frequency DDR3). We can recommend the Samsung 970 EVO M.2 for purchase first of all to avid gamers and computer enthusiasts who already lack the bandwidth of SATA drives. Most importantly, do not forget to check before buying whether the M.2 slot of your PC or laptop supports the NMVe interface or only the slow M.2-SATA.
