Dell 36RH9 1.2TB SAS drive for servers

This Dell 36RH9 is a 1.2TB 10000 RPM SAS hard drive in a 2.5 inch form factor built for Dell PowerEdge servers. It suits administrators who need high-speed spindle storage in hot-swap bays for transactional workloads or database logging. The drive is new and ships in retail or OEM packaging.

SAS 6Gb/s interface limits sustained throughput

The drive uses a SAS interface standard rated at 6Gb/s which caps the maximum sustained transfer rate well below modern solid-state alternatives. Random I/O performance is constrained by the 10000 RPM spindle speed and mechanical seek latency. Workloads that demand consistent sub-millisecond latency or sequential bandwidth above the interface ceiling will hit a hard ceiling.

Hot-swap 2.5 inch tray fits listed PowerEdge models

The 2.5 inch form factor mounts directly into hot-swap trays on the compatible PowerEdge servers listed in the specifications including the M610 R620 R730 and T630 families. Hot-swap support allows drive replacement without powering down the chassis reducing downtime during maintenance. Buyers who need larger capacities or non-Dell chassis should verify tray and backplane compatibility before purchase.

Questions about this item

Should I pick the 1.2TB model or is there a larger capacity option?

The 36RH9 is offered in a single 1.2TB capacity; no larger version of this part number exists.

What does the 10000 RPM spindle speed deliver in a live server?

10000 RPM reduces average latency and raises sustained throughput for random I/O workloads such as databases or virtualisation.

The SAS 6Gb/s interface — what real-world ceiling does that impose?

The 6Gb/s SAS link caps the maximum transfer rate at roughly 600 MB/s, which is the practical ceiling for this drive.
