Where the two actually differ on the specs we track (3 of 11). Matching specs are omitted.
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Three whitelisted labs (Tom's Hardware, StorageReview, PCWorld) benchmarked the 2TB WD_Black SN8100 and rate it among the fastest consumer Gen5 SSDs tested, with class-leading synthetic throughput and top-tier random IOPS plus strong power efficiency. Tom's Hardware and PCWorld flag premium pricing; PCWorld also hit write-speed inconsistency on an older motherboard that vanished on a new test bed. (TechPowerUp's review was dropped because only its intro/spec page was retrievable, leaving no verifiable quotes or measurements.) (3 sourced reviews, 3 lab-tested.)
Praised: Fastest consumer Gen5 SSD tested; record-setting synthetic throughput and top-tier random-read IOPS; Power-efficient and runs cool (peak under 50 degrees C in PCWorld's testing); Excellent all-around real-world performance, including gaming, DirectStorage and AI-model loading.
Flagged: Premium pricing versus Gen4 and rival Gen5 drives; Real-world gains over the best drives are small; overkill for most users; Write-speed inconsistency / severe drops on an older motherboard slot.
Three whitelisted labs benchmarked this PCIe 5.0 drive - StorageReview and Tom's Hardware on the 2TB, Notebookcheck on the 8TB. All rate it among the fastest Gen5 SSDs, with StorageReview and Notebookcheck measuring chart-topping sequential throughput (~14,600-14,890 MB/s), and Tom's Hardware calling it a faithful followup 'bringing much higher performance.' Every surviving source flags premium pricing above competing Gen5 SSDs. (TechPowerUp was dropped in verification - its fetched page contained no confirmable quotes or measurements.) (3 sourced reviews, 3 lab-tested.)
Praised: Class-leading sequential read/write throughput (~14,600-14,890 MB/s measured); Power efficiency and low heat output from the 6nm SM2508 controller; Stable sustained performance with no throttling when adequately cooled.
Flagged: Premium pricing above competing Gen5 SSDs; Offers little to distinguish it from rival high-end SSDs on real-world speed/value; Ships with no cooler; needs at least a passive heatsink to sustain peak load.
