MSI SPATIUM M482

What it brings

Rated up to 7,300 MB/s sequential read, 6,400 MB/s sequential write, 1 million random read and 950,000 random write IOPS at 2 TB.
Manufacturer source
MSI lists 5.7 W maximum operating power, 50 mW PS3 idle and 5 mW L1.2, plus LDPC ECC, end-to-end data path protection and TCG Pyrite support.
Manufacturer source

What to check

The data sheet has no DRAM cache row and does not state the NAND cell type.
Manufacturer source
Capacities stop at 2 TB, with a 1,200 TB warranty write limit at that size and no published post-cache write speed.

Samsung 990 PRO

What it brings

Rated up to 7,450 MB/s sequential read and 6,900 MB/s sequential write over PCIe 4.0 x4, with up to 1.4 million random read and 1.55 million random write IOPS.
Manufacturer source
TLC V-NAND with a 2 GB LPDDR4 DRAM cache, plus a five-year warranty covering up to 1,200 TB written.
Manufacturer source Manufacturer source

What to check

No factory heatsink, so plan for motherboard or case cooling. Peak write speed relies on the TurboWrite cache, and Samsung does not list a post-cache write speed for this model.
Manufacturer source Manufacturer source
It also works in PCIe 3.0 slots, but its rated speeds need a PCIe 4.0 x4 slot.
