Dell 1.2 TB 10K SAS drive
This 2.5 inch internal hard drive delivers 1.2 TB of storage with a 10000 RPM spindle speed for fast data access. It uses a SAS 12Gb/s interface and includes a 128 MB cache buffer. The drive is designed for Dell PowerEdge Generation 13 servers such as the R330, R430, R530, R630, R730, R730xd, R930, T330, T430, T530 and T630.
SAS 12Gb/s interface impact
The SAS 12Gb/s interface provides a high-speed serial connection that supports dual-port operation for path redundancy. This allows the drive to maintain communication if one controller path fails. The 128 MB cache helps absorb write bursts and improves random read performance in transactional workloads.
Mechanical and interface limits
The 10000 RPM rotational speed generates more heat and vibration than slower drives, requiring adequate chassis cooling. The SAS 12Gb/s bandwidth is shared across all devices on the same backplane, so total throughput depends on the number of active drives. Buyers needing higher capacity per bay or lower power draw should consider alternative drive types.

Questions about this item
How often will the 10000RPM motor and bearings need replacement in a 2.5in SAS drive?
Enterprise SAS drives at 10000RPM are rated for continuous operation; the motor and bearings are not a user-serviceable part and are designed to last the drive's service life.
Does the 12Gb/s SAS interface or the 128MB cache become the bottleneck during sustained writes?
The 12Gb/s SAS interface provides ample headroom; sustained throughput is limited by the 10000RPM mechanical media, not the interface or the 128MB cache.
What power draw and heat output should I expect when this 1.2TB drive runs all day in a PowerEdge server?
Typical 2.5in 10000RPM SAS drives consume roughly 6 to 9 watts active; the 1.0 pound unit dissipates heat within standard server cooling designs.
