Seagate ST373454SS 73GB SAS Hard Drive

Seagate Cheetah 15K.4 73GB 15K RPM 3Gbps Serial SAS / Serial Attached SCSI Hard Drive - Refurbished OEM

Seagate Cheetah 15K.4 73GB 15000 RPM 3.0Gbps Serial SAS / Serial Attached SCSI Hard Disk Drive - Refurbished OEM

The Cheetah 15K.4 is the best performance, lowest cost of ownership, 3.5-inch disc drive. It enables higher performance with fewer drives, while offering the industry's highest reliability. Features Benefits 15K RPM spindle speed   Delivers more I/O's per second than 10K, and faster sustained transfer rates, enabling the same high performance to be met with fewer drives.   Background Media Scan   Proactively scans the media for potential defects during drive idle time without using system bandwidth. It enables incipient errors to be corrected before data is lost.   Enhanced Error Correction Code   Better maintains performance throughout the life of the drive and reduces the probability of lost data.   Fluid Dynamic Bearing Motor   No ball bearings means reduced acoustics and improved reliability.   Full Duty Cycle Reliability   The Cheetah 15K.4 is designed to have the highest reliability, even when in used in demanding applications around the clock, 365 days per year.   Serial Attached SCSI (3 Gb/sec)   Serial Attached SCSI (SAS) enables high-performance 15K SAS drives to interoperate with high-capacity NL35 SATA drives helping simplify and consolidate tiered storage.   Distinctions 30% more IOPS and more than 20% faster response times than 3.5-inch 10K drives The industry's highest reliability, with 1,400,000 hour MTBF

All SAS compatible servers including:
Dell PowerEdge 2900, 2950, 6900, 6950. PowerVault MD1000
