Questions buyers ask about this part

Will the 7.68TB PM9A3 fit my server?

This is a 2.5" U.2 SFF part on PCI Express NVMe 4.0 x4. It fits any bay wired for PCI Express NVMe 4.0 x4. Send us your server model and we will confirm backplane support, firmware level and any bracket or caddy required before you order — that check is part of every order we ship.

What is the endurance rating on the 7.68TB?

1 DWPD (read-intensive). Across 7.68TB of capacity that is approximately 14 PB of total writes over a five-year term, calculated from the drive-writes-per-day rating. Compare that against your workload's measured daily write volume: if you are writing more than 7.7TB a day to a single drive, ask us about the mixed-use alternatives instead.

Should I take the 7.68TB or the 3.84TB?

They are the same drive with different capacity: identical PCI Express NVMe 4.0 x4, 2.5" U.2 SFF and endurance rating. The 3.84TB gives you less capacity per bay at a lower unit cost. Where bays are the constraint — a full backplane, or a rack you cannot grow — the larger capacity is usually cheaper per usable terabyte once you count the chassis it saves. Ask us for both on one quote and compare.

How fast is the 7.68TB PM9A3?

Up to 6,800 MB/s sequential read and up to 4,200 MB/s sequential write, which is what PCI Express NVMe 4.0 x4 allows. Sustained figures under a real mixed workload land lower than the sequential headline — tell us your access pattern and queue depth and we will tell you what to expect rather than quoting the datasheet at you.

Is this Samsung part genuine, and is the warranty intact?

Yes. We supply through authorized distribution only, so the part carries the full Samsung manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
