Product overview
P53553-B21 is an HPE 20TB 7200RPM SAS 3.5-Inch hard Drive. Rebuild time scales with capacity, so a large drive in a parity group is a longer window of exposure. This one spins at 7200RPM. Tell us the RAID level and group size and we will say plainly whether the geometry still makes sense.
Send the quantity you need and we will come back within 48 business hours with availability confirmed, not estimated.

Questions buyers ask about this part
Is P53553-B21 genuine and is the warranty intact?
Yes. It ships new in HPE packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will P53553-B21 work in my server?
Send the server model or the shelf it is going into. Vendor-keyed firmware is the usual reason an identical-looking drive is rejected, so we check that alongside interface and form factor.
Do you accept purchase orders and quote at volume?
Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
