If you are in the market for an NVMe SSD and looking for something that is plenty fast, Western Digital (WD) and Samsung are both offering two excellent drives at their cheapest prices today. These are 2TB and 4TB variants and the WD one also packs a heatsink so you won"t have to worry about heat (NAND flash memory inside SSDs are heat-sensitive).
First up, we have the WD drive in the form of the WD_Black SN850X. The 4TB model of the device that comes with a heatsink is currently just $300 (purchase link under the specs list below) making it an excellent purchase. It is a high performance model and came out on top in a performance degradation test over the likes of Samsung, Crucial, and more. The key specs of the drive are given below:
DRAM cache: 2GB DDR4-3200
Sequential Read Performance: 7300MB/s
Sequential Write Performance: 6600MB/s
Random Read: 1200K IOPS
Random Write: 1200K IOPS
Endurance (TBW): 2400
Operating Temperature: 0°C to 85°C

WD_BLACK 4TB SN850X NVMe Internal Gaming Solid State Drive with Heatsink - Works with PlayStation 5, Gen4 PCIe, M.2 2280, Up to 7,300 MB/s - WDS400T2XHE: $299.99 (Amazon US)
Up next, we have the 2TB and 4TB variants of the Samsung 990 Evo Plus. The major difference between the SN850X and the 990 Evo Plus is the lack of DRAM cache on the latter which means it has to rely on system memory for such caching functionality via the Host Memory Buffer (HMB) technology. Another one is endurance.
An interesting feature of the Evo plus is that it supports PCIe Gen5 interface as well but is limited to two lanes (x2) only and thus does not really provide any actual speed benefit over Gen4.
The key specs of the 2TB / 4TB Samsung 990 Evo Plus are given below:
Sequential Read Performance: Up to 7,250 MB/s
Sequential Write Performance: Up to 6,300 MB/s
Random Read: Up to 1,400,000 IOPS
Random Write: Up to 1,050,000 IOPS
Endurance (TBW): 1,200 TBW (2TB), 2,400 TBW (4TB)
Operating Temperature: 0°C to 85°C
