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.
SPECIFICATIONS SIDE BY SIDE8 topics
SELECTED TOPIC
01 / 08

Cache arrangement

Compare the exact DRAM capacity and cache configuration. Onboard DRAM is a separate specification from a write buffer; neither is a measured performance or reliability rating.

Samsung 970 EVO1 GB LPDDR4 DRAM

Manufacturer specification · Manufacturer's stated DRAM cache capacity for this storage capacity.

Samsung 980Host Memory Buffer (HMB)

Manufacturer specification · Manufacturer feature block describes a DRAM-less design using host memory. No onboard DRAM cache; host memory and TurboWrite remain distinct.

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

Samsung 970 EVO

What it brings

What to check

  • It is limited to PCIe 3.0 x4, so it cannot use the extra bandwidth of a PCIe 4.0 or 5.0 M.2 slot, and writes drop from 2,500 MB/s to 1,200 MB/s once the TurboWrite cache fills.

Samsung 980

What it brings

  • Rated up to 3,500 MB/s sequential read and 3,000 MB/s sequential write, with up to 500,000 random read and 480,000 random write IOPS.

What to check

  • DRAM-less design that borrows system memory through Host Memory Buffer, and it is limited to PCIe 3.0 x4. Peak write speed relies on the TurboWrite cache, and Samsung does not list a post-cache write speed for this model.
