The Samsung 970 EVO Plus is a solid-state drive in the M.2 2280 form factor, launched in February 2019. It is available in capacities ranging from 250 GB to 2 TB. This page reports specifications for the 250 GB variant. With the rest of the system, the Samsung 970 EVO Plus interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the Phoenix (S4LR020) from Samsung, a DRAM cache chip is available. Samsung has installed 92-layer TLC NAND flash on the 970 EVO Plus, the flash chips are made by Samsung. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 13 GB, once it is full, writes complete at 400 MB/s. The 970 EVO Plus is rated for sequential read speeds of up to 3,500 MB/s and 2,300 MB/s write; random IO reaches 250K IOPS for read and 550K for writes.
At its launch, the SSD was priced at 90 USD. The warranty length is set to five years, which is an excellent warranty period. Samsung guarantees an endurance rating of 150 TBW, a typical value for consumer SSDs.
