Seagate Cheetah  ST3300655SS 15K.5 300GB 15K 3.0Gbps Serial Attached SCSI / SAS Hard Drive - Brand New

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
