Ranked #5 in Best PCIe Gen5 NVMe SSDs

With the 9100 Pro, Samsung is back on top of the NVMe SSD leaderboard, delivering PCIe 5.0 performance PCWorld called the fastest they have tested. TechRadar praised it as a fantastic option for professional use while noting it is a poor match for gamers. It carries 1GB of DRAM per terabyte and 236-layer TLC NAND, and reviewers noted the premium pricing makes it excessive for typical users. Professionals who need maximum performance are the fit 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

Instead of chasing peak speed like the rest of this group, the Seagate FireCuda 540 competes on durability and peace of mind. Tom's Hardware said the drive 'sets itself apart with an excellent warranty,' and its specification table puts the 2TB model at 2,000TB written on a five-year term with a three-year Seagate Rescue subscription — a service no rival here offers, and one the same review called 'an excellent addition that sets it apart from the MP700.' 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.
