HP 73 GB SAS 6Gb/s 15 000 RPM
This 2.5-inch internal hard drive delivers 73 GB of storage with a 15 000 RPM spindle speed and 16 MB cache over a SAS 6Gb/s interface. It is built for enterprise notebooks and compact servers that require high-throughput, low-latency mechanical storage in a small form factor. The drive ships new in retail or OEM packaging.
Suits SAS-only bays needing 15 000 RPM performance
The drive fits systems with a native SAS 6Gb/s backplane or controller and a 2.5-inch drive bay. Buyers whose platforms lack SAS connectivity or cannot supply the required signal voltage should look at other options, as the drive will not operate on interfaces other than SAS.
15 000 RPM spindle speed
The 15 000 RPM rotational speed is the single specification that determines whether this drive meets the performance envelope of the target workload. It defines the sustained transfer rate and average latency that the SAS 6Gb/s interface and 16 MB cache are designed to exploit.

Questions about this item
Will the 16 MB cache need replacement over time?
The 16 MB cache is built into the drive electronics and is not a user-serviceable part; if it fails the whole unit must be replaced.
What limit appears first when the 15000 RPM spindle runs continuously?
Sustained operation at 15000 RPM makes thermal output the first limiting factor in a 2.5 inch bay.
How much noise and heat does the SAS 6Gb/s interface add during all-day use?
The SAS 6Gb/s interface itself draws little power; nearly all noise and heat come from the 15000 RPM mechanical spindle.
