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

TEST BENCH AND PROTOCOL

EnterpriseSSD SetupIn testing the HGST SSD800MM, along with all enterprise drives, we focus on long term stability. In doing so, we stress products not only to their maximum rates, but also with workloads suited to enterprise environments.

We use many off-the-shelf tests to determine performance, but we also have specialized tests to explore specific behaviors we encounter. With enterprise drives, you will see that we do not focus on many consumer level use-cases.

Our hope is that we present tangible results that provide relevant information to the buying public.

LATENCY

To specifically measure latency, we use a series of 512b, 4K, and 8K measurements. At each block size, latency is measured for 100% read, 65% read/35% write, and 100% write/0% read mixes.

HGST-AveResp

Before we move too quickly through our results, lets take a minute to look at the average response time.  Every single test, reads, writes and a mixture of the two were all below 1ms.  These are, by far, the lowest numbers that we have seen from a SATA or SAS SSD.

HGST-MaxResp

The maximum latency numbers from the SSD800MM are also outstanding.  Even during our long-term testing, we did not see any sort of hiccups in our latency numbers, which should mean great things for our Advanced Write Testing, lets take a look.

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.

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

Oh really? Perhaps you can send us a link or two to a 12Gbps review (not announcement). Thanks ahead.

These are the first that we are aware of.

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.

You are absolutely correct and thanks. Paul snuck one in there while we were on our way to Computex. Thanks for the heads up!
