HGST SSD800MM SAS 12Gbps SSD and LSI SAS 9300-8e HBA Review – LSI and HGST Intro 12Gbps To The World

INSIDE THE HGST ULTRASTAR SSD800MM

The SSD800MM is housed in a 15mm, 2.5″ aluminum housing.  There are a total of 8 screws holding it all together; 4 holding the top cover and 4 holding the main board to the back assembly.

HGST-Open

After taking off the top cover you notice a conductive pad between the NAND and the housing.  Removing the main board exposes conductive pads on the other side of the housing.

HGST-Controller

The controller is a joint venture between Intel and HGST and has 12 channels.  Next to the controller are two DDR3 DRAM packages from Micron that total 1GB.

HGST-NAND

Each side of the board has 9 enterprise 25nm MLC NAND packages, for a total of 18.  Each package contains 32GB of NAND for a total of 576GB in our 400GB version.  Large amounts of over-provisioning is common on enterprise SSDs, but at 44%, HGST is on the high side.

Finally, instead of a large bank of surface-mount capacitors, HGST followed Intel’s S3500/S3700 lead with a single through-hole capacitor.

  1. I’ve long been a proponent of running virtualization environments totally under SSDs. This 12G technology should be the convincer. Would have liked to see some RAID 0 benchmarks run with 4 and 8 SSD units. Curious as to how linear the performance gains would be.

    • This will come in time and obtaining multiple drives for this report was not possible. We always ask as was obvious with our recent Intel and Adaptec/SMART report where we used 24 Optimus SSDs.

  2. Other sites already did 12 gb/s weeks ago! Did you guys miss that?

  3. Tweaktown and storage review have both already done 12Gbs with the true first 12gbs ssd… the toshiba! This isn’t even the first 12gbs ssd.

  4. Three weeks ago….
