FeaturesBenefits
spacer
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

Compatibility

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