## What reviewers say

**Crucial T705** — Four hands-on testers — Tom's Hardware, StorageReview, PCWorld and TechRadar — each benchmarked the Crucial T705 and agree it is the fastest consumer PCIe 5.0 SSD at launch, with sequential reads near 14,400-14,500 MB/s. All four flag the steep price. Tom's Hardware and TechRadar additionally warn about heavy heat and power draw, while PCWorld and StorageReview note that the synthetic wins seldom translate to real-world or 4K workloads. (4 sourced reviews.)

**Seagate FireCuda 540** — Three whitelisted testers hands-on benchmarked the 2 TB FireCuda 540: Tom's Hardware and StorageReview at its 2023 launch, and TechPowerUp in a 2025 re-review. Consensus: a fast PCIe 5.0 drive with high sequential throughput, class-leading sustained/full-drive write speeds, and a standout support package (high TBW endurance plus 3-year data recovery), offset by poor power efficiency, high heat, and a hard requirement for a heatsink to avoid throttling. Both later-lens findings and StorageReview's enterprise tests show it only marginally leads top Gen 4 drives in real use and is weak in some write workloads. (3 sourced reviews.)
