Enterprise storage drive
The HGST HUA721010KLA330 is a 1TB 3.5-inch internal hard drive built for enterprise storage workloads. It spins at 7200 RPM with a 32MB cache and connects through a SATA 3.0Gb/s interface. The drive includes Data Lifeguard and Shock Guard features for data protection.
Suited for always-on arrays
This drive suits servers and NAS units that need continuous operation and consistent throughput. The 300 MBps media transfer rate supports sustained sequential workloads. Builders who need a second card or buyers who want more storage in a smaller form factor should look at something else.
SATA 3.0Gb/s interface decides fit
The SATA 3.0Gb/s interface is the single specification that determines whether this drive fits your system. It requires a compatible SATA port and 3.5-inch bay with standard power and data cables. Average seek time is 8.2 ms for random access patterns.

Questions about this item
How often should I check the 32 MB cache for errors or plan to replace it?
The 32 MB cache is part of the drive's controller board and has no separate maintenance schedule; if the drive develops read or write errors, the whole unit is replaced.
Will the 8.2 ms average seek time become a bottleneck before the 300 MBps media transfer rate during sustained workloads?
The 8.2 ms average seek time is the first limit you hit during random sustained workloads, while the 300 MBps media transfer rate applies to sequential transfers.
How much heat and noise does the 7200 RPM mechanism produce when running all day in a 3.5" bay?
The 7200 RPM spindle generates typical enterprise-level heat and audible seek noise; ensure the 3.5" bay has active airflow to keep temperatures within the drive's operating range.
