Silver 3.5 inch SAS hard drive with green circuit board

Hitachi, Ltd.

Hitachi, Ltd. HUS156030VLS600 300 GB 15000 RPM 64 MB 3.5" SAS

SKU CH-J26R-V1PMH MPN HUS156030VLS600

A 300 GB internal hard drive with a 3.5" form factor, 15000 RPM spindle speed and 64 MB buffer using a SAS interface

  • 300 GB capacity stores critical datasets
  • 15000 RPM spindle speed accelerates transaction processing
  • 64 MB buffer smooths burst I/O workloads
  • 6Gb/s SAS interface ensures reliable enterprise connectivity
  • 5-inch form factor fits standard server bays

300 GB 15K SAS enterprise drive

This 3.5-inch internal hard drive spins at 15000 RPM with a 64 MB buffer and a 6Gb/s SAS interface. It delivers 300 GB of storage in a 1-inch high form factor weighing approximately 1.65 lb. The Ultrastar 15K600 series targets high-performance enterprise storage arrays and servers.

Ideal for high-IOPS transactional workloads

Suits database servers, online transaction processing and tier-0 storage tiers that demand sustained 15K RPM throughput. Not for buyers who want more storage capacity per drive, builders who need a second interface option, or environments that cannot accommodate a 3.5-inch SAS bay.

6Gb/s SAS interface decides compatibility

The drive connects exclusively through a 6Gb/s SAS port and requires a compatible controller or backplane. Confirm the host system supports this interface standard before purchase.

Questions about this item

How do I install the 3.5" SAS drive and what step is often missed?

Mount the drive in a 3.5" bay, connect the SAS data and power cables, then ensure the host controller detects the 6Gb/s link speed before initializing the volume.

What maintenance or replacement will the Ultrastar 15K600 need later?

The 15000 RPM mechanical drive has no user-serviceable parts; plan replacement when SMART attributes report reallocated sectors or excessive seek errors.

What limit appears first during sustained use of the 300 GB 15K600?

Continuous write workloads hit the 64 MB buffer ceiling quickly, after which throughput drops to the native media transfer rate of the spinning platters.
