Samsung's 970 Pro and 970 Evo SSDs are insanely fast


Samsung today announced its third generation PRO and EVO consumer solid state drive lineup. The sequential write speeds represent an enhancement of up to 30 percent over the previous generation owing to the latest V-NAND technology and the newly designed Phoenix controller.

For years now, Samsung has been a giant in the SSD market thanks to consistent releases of high-performing drives. The 970 EVO will arrive in 250GB, 500GB, 1TB and 2TB capacities, while the PRO will only be available in 512GB and 1TB capacities for the time being. Pricing starts at $119.99 for the 970 Evo and $329.99 for the 970 Pro. While the 1TB 970 EVO matches the 600TB of the 512GB 970 PRO. They're both M.2 2280 (the form factor we used to create a cheap 1TB thumb drive a while ago) with PCIe Generation 3 x4 lane.

The results are frankly bonkers - the 970 Pro can offer 3500MB/s of read (sequential) and 2700MB/s write (slightly less for the Evo - 3500MB/s and 2500MB/s). The 960 Evo achieves up to 3,200 MB/s max read speed and 1,900 MB/s max write speed, but the 970 Evo bumps read speed to 3,500 MB/s and write speed to 2,500 MB/s.

Samsung will guarantee the drives for 1200 terabytes written (TBW) or five years, whichever is the longer, and for internal drives, that probably means the lifetime of the host device.

Samsung said the SSDs further offer Dynamic Thermal Guard technology, which protects against overheating by automatically monitoring and maintaining optimal operating temperatures.

The new Samsung 970 PRO and 970 EVO receives upgrades from their predecessor in terms of transfer speeds - both for read and write.
