Tech Specs


  • Mercury Accelsior E2 PCIe SSD
  • QuickStart guide

Detailed Specs

  • Dual SandForce SF2281 processors
    NAND Flash Components
  • Tier-1 synchronous MLC NAND flash storage
  • PCIe 2.0 x2
    Expansion Ports
  • (2) eSATA 6Gb/s port
  • Notes:
    • Not compatible with port-multiplier enclosures.
    • A sleep conflict may be encountered when using certain eSATA chipsets via the eSATA ports when booted to the Accelsior E2. When using Oxford 944 or 946 chipsets, system sleep mode MUST be disabled in order to ensure reliable operation. Allowing system sleep to occur while one of the affected external drives is connected via the Accelsior E2 eSATA ports could result in loss of data following wake from sleep.
