Silver 3.5 inch SAS hard drive mounted in a black system caddy tray

IBM

IBM HUS156030VLS600 300GB 15000RPM SAS 6Gbps 3.5" internal hard drive

SKU CH-EDRN-3494X

300 GB 15000 RPM SAS 6 Gbps internal hard drive with 16 MB cache and included system caddy

  • 300 GB capacity stores more enterprise data
  • 15000 RPM spindle speed accelerates random I/O
  • SAS 6Gbps interface sustains high-throughput workloads
  • 16 MB cache buffers burst traffic
  • Hot-swap tray enables drive replacement without downtime

300 GB 15K SAS drive for servers

This 3.5 inch internal hard drive delivers 300 GB of storage on a 6 Gbps SAS interface. It spins at 15000 RPM with a 16 MB buffer and ships new in a system caddy for hot swap bays. The drive suits enterprise arrays and transactional workloads that demand consistent low latency.

SAS 6 Gbps interface limits

The 6 Gbps SAS link caps sustained throughput below the drive's peak media speed. Sequential reads and writes will saturate the bus before the platters reach their maximum transfer rate. Random IOPS benefit from the high spindle speed but cannot exceed the controller's command queue depth or the link's bandwidth ceiling.

300 GB capacity for hot data

Three hundred gigabytes accommodates operating systems, databases and active project files on a single spindle. The small footprint fills quickly with media libraries, backups or virtual machine images. Workloads that grow beyond this limit need additional spindles or a higher capacity tier.

Questions about this item

Is the 300GB capacity the only option for the HUS156030VLS600?

The model HUS156030VLS600 is offered in a single 300GB capacity. Other part numbers such as 49Y1860, 49Y1859 and 49Y1856 refer to the same 300GB drive with the included system caddy.

What does 15000RPM mean for everyday server workloads?

The 15000RPM spindle speed reduces rotational latency and sustains high random IOPS, making the drive suitable for transactional databases and other latency-sensitive applications.

What does the SAS 6Gbps interface limit in practice?

The SAS 6Gbps link caps the maximum host transfer rate at 6Gbps, so sustained throughput will not exceed that ceiling even if the drive media could deliver more.
