How to read this comparison

Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Check the connection before the capacity. M.2 NVMe modules and 2.5-inch SATA drives are not interchangeable. Check the host’s protocol, slot or bay, power connection and clearance. Rated speeds use different test systems; we do not turn them into a speed score or overall winner.

What it brings

Rated up to 7,250 MB/s sequential read and 6,450 MB/s sequential write, with up to 850K random read and 1.2 million random write IOPS at 2 TB.
Manufacturer source Manufacturer source
Samsung lists AES 256-bit encryption with TCG Opal 2.0 and IEEE 1667, a 3 mW PS4 sleep state, and Samsung Magician support for data transfer, drive health and firmware updates.
Manufacturer source Manufacturer source
Samsung claims up to 38% better sequential performance per watt than the 990 PRO in its own 2 TB test, and the drive is backward compatible with PCIe 3.0.
Manufacturer source Manufacturer source

What to check

The limited warranty is 3 years or 800 TB written, whichever comes first.
Manufacturer source Manufacturer source
Samsung specifies Host Memory Buffer caching and lists no onboard DRAM. Peak write figures use Intelligent TurboWrite, and no post-cache write speed is published.

Samsung 990 PRO with Heatsink

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

The fitted heatsink makes the drive 25 mm wide and 8.88 mm tall, so check clearance, and Samsung says not to remove it. Peak write speed relies on the TurboWrite cache, and Samsung does not list a post-cache write speed for this model.
Manufacturer source
It also works in PCIe 3.0 slots, but its rated speeds need a PCIe 4.0 x4 slot.
