Seagate 1200 Enterprise 400GB 1.8" SAS 12Gb/s SSD

The Seagate ST400FM0253 is a 400GB enterprise solid state drive that connects through a 12Gb/s SAS interface and fits into a space saving 1.8 inch bay. Built for servers and storage systems that cannot afford delays, it replaces mechanical drives with flash memory that responds in microseconds.

Data moves quickly because the drive combines the high bandwidth SAS link with a 2GB cache that smooths bursts of traffic. The result is predictable throughput even when multiple virtual machines compete for resources or a database issues intensive write operations.

Downtime is kept in check by a dual port SAS architecture that provides redundant paths to data. If a cable, controller, or path fails, the second channel keeps transactions moving without administrator intervention. Advanced error detection and correction work in the background to maintain data integrity during every read and write cycle.

Security is addressed at the hardware level through self-encrypting drive technology. Every bit that lands on the NAND is protected by AES encryption, and keys never leave the drive, which helps organizations meet regulatory requirements without sacrificing performance.

Because of these capabilities, the ST400FM0253 slots naturally into blade servers, high density storage arrays, and edge appliances where space is tight and workloads are demanding. It is well suited for virtual desktop pools, online transaction processing, and analytic queries where consistent response time matters.
