Our take on the WD Black SN7100 1TB M.2 NVMe

The WD Black SN7100 is a 1TB M.2 2280 NVMe SSD on PCIe 4.0, rated at 7250 MB/s sequential read and 6900 MB/s write. It is a DRAM-less drive built on WD's current BiCS TLC NAND, aimed at gaming PCs, laptops and PS5 storage expansion. It sits below the SN850X in WD's lineup: slightly lower peak speeds and no DRAM cache, but it runs cooler and draws less power, which suits slim laptops and handhelds. Reviewers rate it as a strong value PCIe 4.0 drive that stays close to flagship speeds in everyday use.

Pros
  • High sequential ratings: 7250 MB/s read, 6900 MB/s write
  • Runs cool and draws little power, good for laptops and handhelds
  • M.2 2280 single-sided format fits most slots, including PS5
  • TLC NAND with a five-year warranty
  • Close to flagship PCIe 4.0 drives in real-world game and app loading
Cons
  • No DRAM cache, so sustained writes can slow once the SLC cache fills
  • Peak speeds trail the SN850X and other DRAM-equipped flagships
  • Not a PCIe 5.0 drive, so no headroom for newer platforms
  • Heatsink not included on all versions

What reviewers say

Reviewers and owners describe the SN7100 as a fast, cool-running PCIe 4.0 drive that delivers most of the feel of a flagship SSD for less. They praise its low power draw and temperatures, and note that heavy sustained writes expose the lack of DRAM.

What people mention
  • SpeedPraisedOwners say game and app loading feels as quick as on pricier PCIe 4.0 drives.
  • ThermalsPraisedReviewers note it runs cool and draws little power, which helps in laptops and handhelds.
  • Sustained writesCriticisedLong file copies slow down once the SLC cache is exhausted, a side effect of the DRAM-less design.
  • ValuePraisedReviewers call it one of the better-balanced PCIe 4.0 drives for the money.
  • DRAM cacheMixedThe lack of DRAM is noted as a trade-off, though most say it barely matters for gaming.

Questions and answers

Is the SN7100 fast enough for gaming?
Yes. Its 7250 MB/s read rating and quick random access put game load times close to flagship PCIe 4.0 drives. Most players will not notice a difference in play.
Does it fit a PS5?
Yes. It is a single-sided M.2 2280 drive, the format the PS5 accepts. You still need to add your own heatsink if the console requires one.
How does it compare with the SN850X?
The SN850X has a DRAM cache and higher peak speeds. The SN7100 runs cooler and draws less power, and in everyday gaming the gap is small.
Does it have a DRAM cache?
No. It uses host memory buffer instead. That keeps it cool and efficient, but sustained writes can slow once the SLC cache fills.
What is in the box?
The drive itself, in M.2 2280 format. Mounting screws and a heatsink are not guaranteed, so check your motherboard or console accessories.
Is it worth it over a cheaper PCIe 3.0 drive?
Yes, if your system supports PCIe 4.0. The SN7100 roughly doubles sequential bandwidth over PCIe 3.0 drives and stays cool, so it is a sensible step up.
Where is the WD Black SN7100 1TB M.2 NVMe cheapest?
At Newegg.com, for $99.00, 43% under what the other stores charge, as of our latest check.
