Samsung PM9A3 3.84TB PCIe 4.0 x4 NVMe U.2

A 3.84TB enterprise drive with consumer-grade endurance and a connector most PCs can't use. Unless your server demands U.2, your money is better spent elsewhere.

The speed numbers land at 64th percentile, which is solid but not exciting for PCIe 4.0. Random performance is even more middle of the pack at 59th percentile. What surprised us is the endurance rating, just 14th percentile. For an enterprise drive, that's genuinely disappointing. You'd expect a drive built for server workloads to laugh at consumer endurance numbers, but this one doesn't. The feature set is also bare at 15th percentile, so don't expect fancy caching tricks or consumer-friendly software.

Stacked against the Western Digital Black SN850X or Kingston Fury Renegade 4TB, the PM9A3 looks lost. Those consumer drives deliver better speed percentiles, actual feature sets, and M.2 compatibility for a fraction of the price. The Micron T710 is the more interesting comparison since it's also enterprise-flavored, but even that drive offers a more balanced package. The PM9A3's only real advantage is raw capacity in a single U.2 slot, and that's a narrow win.

At roughly $2,000 USD, this is a tough sell for anyone outside a specific enterprise use case. You're paying enterprise pricing for a drive that underperforms on endurance and features. For that money, you could buy multiple high-end consumer NVMe drives with better speed and way more flexibility. Unless your server literally requires U.2, this isn't the value play.

The Samsung PM9A3 is an enterprise U.2 drive that somehow ended up on a consumer shelf, and it shows. You get a massive 3.84TB of PCIe 4.0 storage in a 2.5-inch form factor most desktops can't even plug into without an adapter. The capacity is the star here, sitting in the 87th percentile, but almost everything else about this drive screams 'data center, not your gaming rig.'

If you're building a gaming PC or a general-purpose workstation, this isn't your drive. The U.2 connector alone makes it a pain, and the endurance numbers don't justify the enterprise price tag. Go grab a WD Black SN850X or Kingston Fury Renegade instead. You'll get better speed, actual features, and money left over for more storage.

Skip this unless your server or workstation specifically demands a U.2 drive and you need 3.84TB in one slot. For everyone else, there are faster, cheaper, and more practical options. The PM9A3 is a niche product that doesn't even excel at its own niche.
