Ranked #3 in Best PCIe Gen5 NVMe SSDs

Corsair MP700 Pro SE

4.4

8 sources$699.99as of Aug 1

The Corsair MP700 Pro SE comes within reach of the fastest consumer NVMe SSD crown, tying with the Crucial T705. PCWorld's Jon Jacobi found it only slightly behind the competition, with a 2GBps speed boost coming from upgraded 2,400MT/s NAND. The warranty runs a generous 5 years at 750TBW per TB of capacity, and an optional heatsink cooler is available. At $625 for 4TB it sits at the high end, though not outrageously so given the performance and warranty. Enthusiasts and power users who demand peak performance are the fit; casual users will find better value elsewhere.

Strengths

— Achieved near-top performance, tying with Crucial T705 for fastest consumer NVMe SSD tested
— Upgraded 2,400MT/s NAND delivers 2GBps faster speeds than previous MP700 Pro model
— Includes 5-year warranty with 750TBW per TB capacity, exceeding industry standard

Watch-outs

— Priced at $625 for 4TB model, making it expensive for a PCIe 5.0 SSD
— No pricing available for base 2TB version, though Hydro X series is $355
— Not the outright fastest: PCMag ranks it the second-fastest internal SSD it has tested, behind the Crucial T705

Higher ratedRanked #1 in Best PCIe Gen5 NVMe SSDs

Crucial T705

4.5

11 sources$267.95as of Aug 1

Sequential reads up to 14.5GBps put the Crucial T705 ahead of its competitors in synthetic benchmarks. PCWorld's Jon Jacobi noted its 'blazingly fast benchmarking' and 'very good overall performance,' while stressing how 'extremely pricey' the drive is. PCMag's Tony Hoffman rated it five stars and called it 'the fastest internal solid-state drive (SSD) we've ever tested,' while noting it 'is priced higher than other PCIe 5 SSDs we've tested,' so the real-world gains may not justify the premium for most users. Enthusiasts and professionals chasing maximum performance are the fit; casual users will find more value in older-generation SSDs.

Strengths

— Blazingly fast benchmarking with 14.5GBps sequential read speeds
— Uses latest Phison PS5026-E26 controller and 232-layer TLC NAND
— Very good overall performance in synthetic tests

Watch-outs

— Extremely pricey at $240 for 1TB, $400 for 2TB, $690 for 4TB
— Windows transfers are only average despite high benchmark scores
— Premium pricing may not justify performance gains for typical users

How they stack up

Corsair MP700 Pro SE

The Corsair MP700 Pro SE is the value enthusiast pick among the Phison-controller drives, effectively tying the Crucial T705 for top-tier consumer speed while adding a 5-year, 750-TBW-per-TB warranty and an optional cooler. It shares the hot-running Phison controller with the Crucial T705 and Seagate FireCuda 540, so it trails the cooler, faster WD Black SN8100, and it is pricier than the Crucial T705 at 4TB. It lacks the Samsung 9100 PRO's 1GB-per-TB DRAM. Pick it over the Crucial T705 for the warranty and cooler bundle; pick the WD Black SN8100 if thermals and outright speed lead.

Crucial T705

The Crucial T705 posts the highest synthetic sequential speeds among the Phison-controller drives at up to 14.5 GB/s, narrowly ahead of the Corsair MP700 Pro SE, but its real-world Windows transfers are only average and it shares the Phison controller's heat, running hotter than the WD Black SN8100. It is cheaper than the Corsair MP700 Pro SE and lacks the Samsung 9100 PRO's 1GB-per-TB DRAM and the Seagate FireCuda 540's data-recovery warranty. Choose it over the Corsair MP700 Pro SE for the best benchmark numbers at a lower price; choose the WD Black SN8100 for better efficiency and real-world performance.
