This new PCIE Gen4 SSD from Samsung can produce a sequential read speed of up to 7000 MB/s and a sequential write speed of up to 5000 MB/s. This is all thanks to its in-house designed “Elpis” SSD controller. Right … this WILL be my next purchase for sure!
Taken from TPU … Samsung’s hotly anticipated 980 PRO M.2 NVMe flagship client-segment SSD is the company’s first “PRO” branded SSD to feature TLC NAND flash memory, breaking from a unique tradition of using MLC (2 bits per cell) NAND flash. Product pages of the drive went live, and its specifications clearly state the use of “Samsung V-NAND 3-bit MLC,” which is another way of saying TLC. “MLC” generally referred to as NAND flash memory that stores 2 bits per cell, even through the term “Multi-level” is amorphous.
The product page lists other juicy specs of Samsung’s first M.2 NVMe client SSD that takes advantage of PCI-Express gen 4. The drive uses Samsung’s in-house design “Elpis” controller, which uses NVMe 1.3 protocol over PCI-Express 4.0 x4, and an LPDDR4 DRAM cache. The 980 PRO comes in capacities of up to 1 TB, with up to 1 GB of DRAM cache. Samsung rates the 1 TB version as capable of up to 7000 MB/s sequential reads, up to 5000 MB/s sequential writes, and up to 1 million IOPS 4K random reads/writes at QD32. The use of TLC impacts endurance adversely in comparison to that of the drive’s immediate predecessor, the 970 PRO, with the 1 TB 980 PRO warranty covering only up to 600 TBW, in comparison to 1200 TBW of the 970 PRO 1 TB, and the 500 GB 980 PRO offering just 300 TBW warranty coverage in comparison to 600 TBW of the 970 PRO 512 GB.
