Questions buyers ask about this part

Will the 960GB SM863a fit my server?

This is a 2.5" SFF part on 6Gb/s SATA. It fits any bay wired for 6Gb/s SATA. 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 960GB?

3 DWPD (mixed use). Across 960GB of capacity that is approximately 5.3 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 2.9TB a day to a single drive, ask us about the mixed-use alternatives instead.

Should I take the 960GB or the 1.92TB?

They are the same drive with different capacity: identical 6Gb/s SATA, 2.5" SFF and endurance rating. The 1.92TB gives you 2.0x the capacity per bay. 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 960GB SM863a?

Up to 560 MB/s sequential read and up to 530 MB/s sequential write, which is what 6Gb/s SATA 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.

We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.
