900GB 10K SAS drive for ThinkServer
This 900GB 2.5" SAS hard drive spins at 10000RPM and provides a 6Gb/s interface with 64MB cache. It is built for ThinkServer RD430, RD440, RD630 and RD640 systems. The drive suits administrators who need fast, high-capacity storage in a small form factor for enterprise workloads.
Check SAS backplane and controller
Verify that your server has a 2.5" SAS backplane and a controller that supports 6Gb/s speeds before ordering. The drive uses a standard SAS connector and fits the listed ThinkServer models directly. Buyers who need a different interface or larger 3.5" form factor cannot use this unit.
Thermals noise and power in normal use
The 10000RPM spindle and 2.0 pound weight indicate typical enterprise drive acoustics and heat output for this class. Normal operation will generate measurable vibration and warmth inside a populated chassis. Ensure your server cooling is designed for multiple high-speed SAS drives.

Fragen zu diesem Artikel
Does the ST900MM0006 ship with a mounting bracket or caddy for the 2.5" bay?
The drive is supplied as the bare 2.5" SAS unit; any carrier or bracket required by the ThinkServer RD430, RD440, RD630 or RD640 chassis must be sourced separately.
I see several Lenovo part numbers listed — 03T7739, 0C44527 and 0A89409 — which one should I order?
All three part numbers reference the same ST900MM0006 model with 900 GB capacity, 10 000 RPM speed, SAS 6 Gb/s interface and 64 MB cache; choose the part number that matches your server's service documentation.
What does the 10 000 RPM rating mean for daily workloads on a ThinkServer RD640?
The 10 000 RPM spindle delivers higher random IOPS and lower average latency than slower drives, improving database and virtualization performance on the RD640's SAS backplane.
