## What reviewers say

Two whitelisted testers survived verification for the 2TB SN7100: Tom's Hardware and PCWorld. Both credit the drive with strong performance for a DRAM-less HMB design and excellent random reads; Tom's additionally singles out chart-topping power efficiency. They split on the overall verdict and value — PCWorld crowns it the fastest PCIe 4.0/HMB drive it has tested and 'number one for the average user' at an affordable price, while Tom's Hardware calls it 'largely unimpressive' apart from efficiency and flags pricing above competitors, including WD's own faster SN850X. TechPowerUp's draft entry (which had rated it best-in-class) was dropped: the fetched page returned only its intro/specs section, so none of its quotes or measured values could be confirmed. (Based on 2 reviews, 2 lab-tested, 2025-02-07–2025-03-12.)

Praised: Class-leading / chart-topping power efficiency; Strong performance for a DRAM-less HMB design, especially random reads; Affordable / competitively priced for its class; Five-year warranty.
Flagged: Mediocre all-around performance; not the fastest overall; Sustained / post-cache writes drop to a stable ~500MBps to nearly 1GBps on native TLC; No 4TB option at launch; Priced above competitors, including WD's own faster SN850X.
Disagreement: The value/verdict is genuinely split between the two surviving sources. PCWorld names it 'number one for the average user' and 'affordable,' calling it the fastest PCIe 4.0/HMB drive it has tested. Tom's Hardware, by contrast, rates it only 'competent' and 'largely unimpressive' aside from its power efficiency, and argues its current pricing runs above competitors — sometimes above WD's own faster SN850X. (TechPowerUp, which had crowned it 'the best SSD,' was removed in verification because its fetched page lacked all cited quotes and measured values.)
