The 1TB drive we are looking at is at the top of the product stack, and clocks in at 3500MB/s read and 3000MB/s write per the spec sheet. The Samsung 980 line of SSDs is available from 250GB to 1TB. However, its function as a heat spreader seems to mostly be marketing since it is both on the wrong side of the drive and also physically distant from the controller. Samsung claims this label is a heat spreader, and indeed it appears to be a thin copper strip. Since this is a single-sided drive, the back has nothing but a product label. This design is very reminiscent of the WD Blue SN550 1TB, with the single NAND package and physical separation between the NAND and the controller. Samsung 980 1TB Frontīeneath the product label is Samsung’s 4-channel Pablo controller, a single NAND package, and not much else. The Samsung 980 1TB comes in a single-sided M.2 2280 (80mm) form factor. Samsung’s 980 is essentially their entry-level NVMe SSD, with a number of major departures from the 970 EVO line, chief among which is the lack of a DRAM cache. This drive is pitched as a successor to the 970 EVO line of drives and is a PCIe 3.0 SSD, unlike the 980 Pro which is PCIe 4.0. Today we are taking a look at the Samsung 980 1TB SSD.
