THE DIFFERENCES, MADE VISIBLE

Visual facts

Differences first. Select a topic for its graphic, sources and conditions.

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.

Storage capacity

Decimal storage capacity: 1 TB = 1,000 GB. Formatting and system use reduce available space.

Kingston KC30002.05 TB

Manufacturer specification · Manufacturer-listed capacity; formatting and reserved functions reduce usable storage.

Samsung 990 PRO2 TB

Manufacturer specification · Decimal capacity; usable formatted space is lower.

Explore the full specifications

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 EACH CHOICE ASKS OF YOU

What it brings and what to check

Kingston KC3000

What it brings

  • Rated up to 7,000 MB/s sequential read and 7,000 MB/s sequential write over PCIe 4.0 x4, with up to 1 million random read and write IOPS.

What to check

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.
  • TLC V-NAND with a 2 GB LPDDR4 DRAM cache, plus a five-year warranty covering up to 1,200 TB written.

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.
  • It also works in PCIe 3.0 slots, but its rated speeds need a PCIe 4.0 x4 slot.
