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
