Samsung 9100 PRO 2TB PCIe 5.0 NVMe SSD

4.3

$426.46as of Jun 7

The Samsung 9100 Pro returns Samsung to the top of the NVMe SSD leaderboard with PCIe 5.0 performance that PCWorld called the fastest they've tested. TechRadar praised it as a fantastic option for professional use but noted it's not ideal for gamers. The drive features 1GB of DRAM per terabyte and 236-layer TLC NAND, though reviewers noted its premium pricing makes it excessive for typical users. It's best suited for professionals who need maximum performance rather than casual consumers.

Strengths

— Fastest benchmarking NVMe SSD tested according to PCWorld
— 1GB DRAM per terabyte for fast random operations
— PCIe 5.0 x4 interface with 236-layer TLC NAND

Watch-outs

— Expensive overkill for most users according to PCWorld
— A hair off the pace in Windows file transfers

Ranked #5 in Best PCIe Gen5 NVMe SSDs

Seagate FireCuda 540

4.2

$949as of Jun 7

The Seagate FireCuda 540 takes a different angle on Gen5 than the speed-chasing drives in this group: it competes on durability and peace of mind. Tom's Hardware praised its 'excellent warranty,' noting it is 'rated for up to 2,000 terabytes to be written over its warranty period of five years, which is higher than the 1,400 TBW endurance featured by competing PCIe Gen5 SSDs,' and it bundles a three-year Seagate Rescue data-recovery service no rival here offers. Its peak speeds of around 10,000 MB/s trail the WD Black SN8100 and Crucial T705, but PCWorld found that 'though it's not the fastest PCIe 5.0 SSD we've seen with synthetic benchmarks, the FireCuda 540 blazed to a first-place finish in our real world 48GB transfers.' The drawbacks are familiar: it runs hot, needs a heatsink, and is priced like a flagship despite not being the fastest.

Strengths

— Class-leading endurance: rated up to 2,000 TBW on the 2TB model, well above the ~1,200 TBW of rival Gen5 drives
— Bundled three-year Seagate Rescue data-recovery service, unique in this group
— First-place finish in PCWorld's real-world 48GB transfer test despite lower peak synthetic numbers

Watch-outs

— Peak sequential speeds of ~10,000 MB/s trail the 14,000+ MB/s WD Black SN8100 and Crucial T705
— Bare drive throttles without a heatsink; needs motherboard or aftermarket M.2 cooling
— Poor power efficiency compared to the SM2508-based WD Black SN8100

How they stack up

Samsung 9100 PRO 2TB PCIe 5.0 NVMe SSD

The Samsung 9100 PRO is the only drive in this group with a full 1GB of DRAM per terabyte, giving it superior random I/O versus the WD Black SN8100, Crucial T705, Corsair MP700 Pro SE, and Seagate FireCuda 540, and it backs that with Samsung's mature Magician software. It trails the WD Black SN8100 in peak sequential speed and efficiency, and it is more expensive than the Crucial T705. Choose it over the WD Black SN8100 if you want Samsung's ecosystem and DRAM-heavy random performance; choose the WD Black SN8100 instead for the fastest, coolest-running option overall.

Seagate FireCuda 540

The Seagate FireCuda 540 is the endurance-and-safety pick of this group: its ~2,000 TBW rating on the 2TB model tops the ~1,200 TBW of the WD Black SN8100, Samsung 9100 PRO, and Crucial T705, and it is the only drive here with a bundled data-recovery service. It uses the same Phison controller as the Corsair MP700 Pro SE and Crucial T705, so it runs hot and trails the WD Black SN8100's efficiency, and its ~10,000 MB/s peak speeds are slower than every other drive in this lineup. Choose it over the faster WD Black SN8100 or Crucial T705 specifically when long-term endurance and the Rescue recovery service matter more than peak benchmarks.
