Seagate 300GB 2.5 inch SAS 3.0 10K RPM Enterprise Internal Hard Drive

Seagate ST300MM0008 / YJ2KH 300GB 2.5″ SFF 12Gbps 10K RPM Enterprise SAS Hard Drive – New Pull OEM

Alt MPN: 0YJ2KH, YJ2KH, 1V8200

General Description
Seagate Enterprise Performance 10K HDD v8 drives provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. The Serial Attached SCSI interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density storage requirements.

The TurboBoost functionality provides improved performance over standard HDDs in real-world workloads. This improvement is due to the addition of a solid state component that caches “hot” data for reads as well as protects write data via non-volatile cache (NVC).

Seagate Enterprise Performance 10K HDD drives are random access storage devices designed to support the Serial Attached SCSI Protocol as described in the ANSI specifications, this document, and the SAS Interface Manual (part number 100293071) which describes the general interface characteristics of this drive. Seagate Enterprise Performance 10K HDD drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard. The SAS connectors, cables and electrical interface are compatible with Serial ATA (SATA), giving future users the choice of populating their systems with either SAS or SATA hard disk drives. This allows integrators to continue to leverage existing investment in SCSI while gaining a 12Gb/s serial data transfer rate.

Seagate Enterprise Performance 10K HDD drives use a dedicated load/unload zone at the outermost radius of the media to eliminate the possibility of destroying or degrading data by landing in the data zone. The heads automatically go to the ramp load/unload when power is removed from the drive and during the deeper sleep modes.

An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping and handling. The shipping lock disengages and the head load process begins when power is applied to the drive.

The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that provides excellent performance with minimal power dissipation in any orientation.
