1 TB SAS drive for servers and arrays

The Dell ST91000640SS is a 1000 GB internal hard drive spinning at 7200 RPM with a 64 MB cache. It uses a 2.5 inch SAS 6 Gb/s interface designed for enterprise storage systems and compatible Dell servers.

Check SAS controller and bay clearance

Verify that your host has a SAS backplane or controller supporting 6 Gb/s links and that the 2.5 inch drive bay accepts the standard enterprise form factor. Confirm firmware compatibility with the Constellation.2 series before installation.

Fits 2.5 inch hot-swap trays and RAID sets

The drive slides directly into 2.5 inch hot-swap carriers used in Dell PowerEdge and similar chassis, requiring no adapter brackets. Its SAS interface enables dual-port redundancy and allows mixing with other SAS disks in RAID arrays.

Questions sur cet article

Does the ST91000640SS ship with any cables, brackets or mounting hardware, or do I need to buy those separately?

The drive is supplied as a bare 2.5" SAS unit; no data cable, power adapter or mounting bracket is included, so you will need to source a compatible SAS cable and a 2.5" drive tray or caddy for your chassis.

The listing mentions a single 1000GB 7200RPM 64MB model — are there other capacities or cache sizes I should consider?

Only the 1000GB capacity with 64MB cache and 7200RPM spindle speed is offered for this ST91000640SS part number; no alternative capacities or buffer sizes exist under the same model.

What does the 6Gb/s SAS interface mean for actual throughput once the drive is installed in a server or RAID controller?

The 6Gb/s SAS link provides a maximum interface bandwidth of 6 gigabits per second; real-world sustained transfer will be limited by the 7200RPM mechanical speed and 64MB cache, typically delivering well below the interface ceiling.
