Capacity and Interface

This is a 900 GB internal hard drive with a SAS 6Gb/s interface spinning at 10000 RPM. It is designed for server environments that demand consistent throughput and low latency. The 2.5 inch form factor fits standard drive bays in rackmount and blade systems. IT administrators handling transactional workloads will find the capacity and speed appropriate.

Build Quality and Mounting

The unit ships with a hot-swap tray so it can be inserted or removed without powering down the chassis. A SAS connector on the tray mates directly to the backplane, eliminating separate cabling inside the enclosure. Mechanical construction follows IBM specifications for vibration tolerance in dense arrays. The drive is supplied new in retail or OEM packaging depending on stock.

Practical Limits of SAS 6Gb/s

The 6Gb/s SAS link caps maximum sustained transfer below the theoretical ceiling once overhead and command queuing are accounted for. Random I/O performance scales with queue depth but cannot exceed the physical spindle speed limit. Workloads requiring higher sequential bandwidth or lower access times will need a faster interface or solid-state media. Buyers who need more storage per spindle or a different protocol should evaluate alternative drives.

Questions about this item

What does the 6Gb/s SAS interface limit in practice?

The 6Gb/s SAS interface caps the maximum theoretical transfer rate at 6Gb/s, so the 10000 RPM drive cannot exceed that bandwidth during sustained reads or writes.

What physical space and mounting does the 2.5 inch drive with hot-swap tray require?

The 2.5 inch form factor fits standard 2.5 inch drive bays and the included hot-swap tray mounts directly into compatible server or storage enclosures.

How is the drive installed and what step is often missed?

Slide the drive into the supplied hot-swap tray, secure it with the tray screws, then insert the assembly into the hot-swap bay until the latch clicks; the step often missed is fully seating the tray so the SAS connector engages completely.
