Seagate Cheetah 15K.5 300GB ST3300655LW 68pin 15K U320 SCSI Hard Drive - Factory Recertified

The Cheetah 15K.5 is mainstream enterprise disc drive storage. It is the best price/performance, lowest cost of ownership, 3.5-inch disc drive, with the industry's highest 3.5" disc drive reliability.
15K RPM spindle speed

Delivers more I/O's per second and faster sustained transfer rates than 10K 3.5-inch drvies, enabling the same high performance to be met with fewer drives.

Background Media Scan (BMS)

Second generation Seagate-exclusive BMS proactively scans the media for potential defects during drive idle time. It enables incipient errors to be corrected before data is lost.

Perpendicular Recording

Perpendicular recording is fundamentally superior, enabling the highest areal density with 30 percent higher performance.

Nonrecoverable Error Rate

The nonrecoverable error rate has been improved by a factor of 10.

Idle Read After Write (IRAW)

Seagate-exclusive IRAW enhances data protection by verifying-during drive idle time-that data in the drive buffer was properly written.

  • The industry's highest reliability 3.5" drive
  • 30% more IOPS and 20% faster response times than 3.5" 10K drives
