WD Black SN7100 1TB NVMe SSD vs Crucial E100 1TB NVMe SSD

The WD_BLACK SN7100 is the clear pick for gaming, video work or any heavy write load: it is roughly 45% faster on reads and more than twice as fast on writes, uses TLC NAND instead of QLC, and carries 600 TBW of endurance against 80 TBW. The Crucial E100 is a budget Gen4 drive with no DRAM cache and QLC flash, so it suits a secondary machine, a media library or a basic upgrade from SATA or a hard drive. Owners rate the SN7100 highly (4.8 from 91 ratings); the E100 is a plain, workmanlike drive with nothing to brag about. If the two sit on the same shelf, the SN7100 is the one worth stepping up to.

  • Choose the WD_BLACK SN7100 if you game, edit video, move large files often, or want a drive that will still be healthy after years of heavy writes.
  • Choose the Crucial E100 if you need cheap Gen4 storage for a secondary system, a media or document library, or a simple upgrade from an older SATA drive.

What reviewers say

WD Black SN7100 1TB NVMe SSD

  • 4.8 / 591 ratings

Reviewers treat the SN7100 as one of the better value PCIe 4.0 gaming drives, praising its read speeds and cool running. They note the DRAM-less design and slower sustained writes as the main trade-offs against pricier drives.

What people mention
  • SpeedPraisedReviewers say reads are fast enough to load games and large files quickly.
  • ThermalsPraisedOwners report it runs cool and draws little power, which suits laptops and compact builds.
  • Sustained writesCriticisedWrite speeds drop once the cache fills during long transfers.
  • DRAM cacheMixedThe DRAM-less design is fine for gaming but noted as a limit for heavy write workloads.

Questions and answers

Which is better for gaming?
The WD_BLACK SN7100. Its faster reads cut load times, and its TLC flash and 600 TBW endurance hold up better as game installs, patches and DLC pile up. The E100 works for a game library but slows on large writes.
Which lasts longer?
The SN7100, by a wide margin: 600 TBW against 80 TBW. That matters if you write large files often. The E100 does carry a stated 3-year warranty, which the SN7100 listing does not spell out.
Is the SN7100 worth stepping up to?
Yes for a main drive in a gaming PC or laptop. It is faster on both reads and writes and far more durable. The E100 makes more sense as secondary storage where speed and write volume are low.
Will the E100 slow down on big file transfers?
Yes. QLC flash with no DRAM cache drops below its rated 3,000 MB/s write speed once its cache fills, so long copies of large files take noticeably longer than on the SN7100.
Do either need a heatsink?
The SN7100 runs warm under sustained writes, so use your motherboard's M.2 heatsink if it has one. The E100 runs cooler at its lower speeds and usually does not need one.
Will both fit my laptop or handheld?
Both are M.2 2280, PCIe 4.0 x4 drives, so they fit the same slot. Check that your device takes a full-length 2280 drive, since some handhelds and compact laptops use shorter 2230 slots.
