Purpose-built 2.5" SAS drive
This IBM ST91000640SS is a 1000GB 7200RPM hard drive with a 6Gb/s SAS interface. It ships new in an IBM System X caddy for direct hot-swap installation in compatible servers. The drive targets administrators who need reliable nearline capacity in a 2.5 inch form factor.
Thermals and power in normal use
At 7.2K RPM the spindle draws modest power and generates limited heat during typical read or write activity. The SAS interface operates at 6Gb/s without additional protocol overhead. Acoustic output remains low enough for rack environments with standard airflow.
Sustained load behaviour
Continuous sequential workloads keep the platters spinning at constant speed, so thermal output stabilises rather than spiking. The SAS link maintains steady throughput for extended backup or archive jobs. The drive is not suited for workloads demanding SSD latency or higher IOPS density.

Spørgsmål om denne vare
How do I install the ST91000640SS with the included System X caddy?
Slide the drive into the supplied caddy until the SAS connector seats firmly, then insert the assembly into a hot-swap bay until the latch clicks. The step often missed is not pushing the caddy far enough for the latch to engage.
What maintenance or replacement will the ST91000640SS need over time?
The 7200RPM mechanical mechanism will eventually wear; plan to replace the drive when SMART reallocated sectors rise or after the rated annualised workload is exceeded.
What limit appears first on the ST91000640SS during sustained writes?
The 6Gb/s SAS interface caps sustained throughput, so sequential transfers plateau at the bus ceiling before the 7200RPM platters become the bottleneck.
