## What reviewers say

**Samsung 9100 Pro** — Three whitelisted labs (Tom's Hardware, TechPowerUp, StorageReview) hands-on-tested the Samsung 9100 Pro, Samsung's first PCIe Gen5 consumer SSD, and agree it is among the fastest and most power-efficient consumer Gen5 drives, with record sequential reads of 14.2 GB/s (TechPowerUp) and 14,600 MB/s (StorageReview). Tom's Hardware and TechPowerUp temper the praise: both flag the premium price and frame the drive as a refined last-generation solution rather than revolutionary, and TechPowerUp additionally documents a sharp post-SLC-cache write drop (to 1.3 GB/s) and throttling without a heatsink. StorageReview is the most upbeat, calling its pricing competitive and the drive one of the most capable on the market. HotHardware was excluded as non-whitelisted. Tom's Hardware's page 2/3 benchmark figures (SLC-cache write, post-cache write, temperature) were not present on the fetched review page and were dropped as unverifiable. (3 sourced reviews.)

**WD_Black SN8100** — 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.)
