HP 800 GB 2.5-inch SATA enterprise SSD
This refurbished HP 717973-B21 drive provides 800 GB of capacity in a 2.5-inch form factor with a SATA 6Gb/s interface. It uses MLC flash memory and is built for server and storage-array workloads that demand consistent write endurance. The drive suits administrators replacing failed units or expanding existing SATA-based arrays.
Sustained write behaviour and latency
MLC flash and the enterprise-grade controller maintain steady throughput during extended write sequences rather than throttling after a short burst. The quoted seek time of .1 ms reflects low latency for random read operations typical of database and virtualization workloads. This consistency helps prevent performance dips during heavy I/O periods.
Thermals, noise and power draw
The solid-state design has no moving parts, so the drive operates silently in normal use. Its slim .38-inch height and 100 g weight allow dense packing in 2.5-inch bays without adding significant thermal load. Power consumption stays within standard SATA limits, simplifying cooling planning for rackmount chassis.

Questions about this item
How much heat and power does the 2.5" SATA drive draw during continuous operation?
The 0.1 ms seek time indicates low mechanical latency, and the 100 g weight reflects a compact design that typically runs cool under sustained workloads.
What host connector and bay size must my server already provide for the 717973-B21?
Your system needs a 2.5" drive bay and a standard SATA 6 Gb/s port to accept the 3.45" × 2.75" × 0.38" form factor.
Will this MLC SATA SSD work reliably alongside older mechanical drives in the same array?
Yes, the SATA interface and 0.1 ms access time let it coexist with legacy HDDs without protocol mismatches or controller conflicts.
