Intel 311 Larson Creek Features

Key Points SRT From Intel Engineering on SRT’s Benefits Over Dual Drives:

  • SRT can provide performance gains across the entire hard drive capacity – no matter how big the hard drive
  • SRT maintains a single drive letter. User only has to manage a C: drive
  • SRT can use an SSD as small as 20GB SLC and provide optimum performance/cost benefit
  • SRT can also provide SSD-like performance gains caching a RAID array of hard disks
    • Solve RAID 5 slowness without sacrificing an additional disk for RAID 10
  • SRT also saves power due to opportunistic spin-down of the hard disk

The Intel SSD 311 Series 20GB SSD has the following general performance ratings:

Random Read/Write IOPS (Input/Output Operations per Second)

  • 4 KB Read - Up to 37,000 IOPS
  • 4 KB Write - Up to 3,300 IOPS

Maximum Sustained Read and Write Bandwidth

  • Sequential Read - Up to 200 MB/s
  • Sequential Write - Up to 105 MB/s

Latency

  • Read - 65 μs (TYP)
  • Write - 75 μs (TYP)
  • Power On to Ready - 1.50 s (TYP)
