DELL 1FE200-157 900GB 10K SAS 12G 2.5in internal hard drive

Dell 900GB SAS 12Gb/s 10K Drive

This 2.5-inch internal hard drive delivers 900GB of storage on a 12Gb/s SAS interface. It spins at 10000RPM with a 128MB cache. The unit ships with an R Series caddy for direct installation in compatible Dell systems. It is built for enterprise workloads needing consistent throughput.

SAS 12Gb/s Interface Limits

The drive operates at the full 12Gb/s SAS signalling rate when the host controller and backplane support it. Performance will drop to the lowest common speed if any link in the chain runs at 6Gb/s or 3Gb/s. Cable length and connector quality also affect sustained bandwidth. Systems without SAS ports cannot use this drive at all.

900GB Capacity and Headroom

The 900GB capacity suits databases, virtualisation hosts and transaction logs that benefit from low latency. The 10000RPM spindle and 128MB cache handle heavy random I/O without saturating quickly. Workloads requiring multi-terabyte sequential storage or archival cold data will exceed the available space. Buyers needing larger single volumes should consider higher-capacity alternatives.
