Silver 2.5 inch SAS hard drive with model label

HGST

HGST HUC156030CSS200 2.5" 300GB SAS 12Gb/s 15K RPM 128M 512N 0B28955 internal hard drive

SKU CH-A9E0-M4Q7Z

2.5-inch 300 GB SAS drive with 12 Gb/s interface, 15K RPM and 128 MB cache

  • 15K RPM speeds up transaction-heavy workloads
  • 12 Gb/s SAS interface moves data fast
  • 128 MB cache smooths burst I/O
  • 512-byte native sectors fit legacy arrays
  • 5-inch form factor fits dense bays

300 GB 15K SAS Enterprise Drive

This HGST HUC156030CSS200 is a 2.5-inch internal hard drive built for 12 Gb/s SAS infrastructure. It delivers 300 GB of storage on a 512N sector format with a 128 MB cache. The 15 000 RPM spindle targets transaction-heavy workloads in compatible servers and arrays.

Database and Transaction Workloads

The drive suits environments that demand sustained random I/O at 15K speeds over a 12 Gb/s SAS link. Systems requiring higher single-drive capacities or a different physical interface will not match this device. Buyers without SAS backplane support should select another storage class.

12 Gb/s SAS Interface Decides Fit

The single specification that determines compatibility is the 12 Gb/s SAS connection. The host controller, backplane and cabling must all support this exact interface and signalling rate. Without confirmed SAS 12G infrastructure the drive cannot operate as intended.

商品問答

Will the 15K RPM spindle require periodic bearing replacement?

The drive is sold new and designed for continuous operation; no user-serviceable bearing schedule is specified by the manufacturer.

What limit appears first during sustained 12Gb/s SAS transfers?

The 15K RPM mechanical latency and 128M cache size constrain sustained throughput before the 12Gb/s interface saturates.

How much heat and power does the 2.5" 300GB drive produce running all day?

The 15K RPM 2.5" form factor generates typical enterprise heat and power levels for a 300GB SAS drive under constant load.
