A little over a year OCZ introduced its first in-house designed enterprise SSD series called the Intrepid 3000. What separated the Intrepid from OCZ's earlier enterprise SSDs was the fact that it utilized a fully custom OCZ firmware with a Marvell silicon, whereas in the past OCZ's enterprise SSDs relied mostly on SandForce controllers with limited customization. Today OCZ is refreshing the lineup by superseding the 3600 with a new 3700 model.

Compared to the Intrepid 3600, the biggest change in the 3700 is the switch to A19nm NAND and the addition of a 1.92TB model. The over-provisioning has also been reduced from 28% to 12%, which yields a higher usable capacity and hence lowers the cost per gigabyte. I suspect that due to the lower over-provisioning OCZ had to go with eMLC to keep the endurance the same (one drive write per day), but now that OCZ is under Toshiba the company has better access to NAND and can source eMLC parts at a much more reasonable price.

As usual to enterprise drives, the Intrepid 3700 features full power loss protection (yes, even data in flight is protected), AES-256 hardware encryption and end-to-end data path protection. There is an internal RAID-like functionality too to protect against NAND-level failures that cannot be fixed using traditional ECC methods. 

Because of the one drive write per day endurance, the Intrepid 3700 is more geared towards read-intensive workloads and the slide above includes some example use scenarios. For mixed workloads, OCZ offers the Intrepid 3800, which has more over-provisioning and larger lithography NAND to provide higher endurance that's needed for more write-centric workloads.

As guidance, OCZ told me that the MSRP for the 240GB model is about $245, but the higher capacities should retail at somewhere between $0.60 and $0.70 per gigabyte, which is fair for an enterprise SSD with full enterprise-grade feature set.

    Table compares "Intrepid 3700" and "Intrepid 3800"... Article compares 3700 and 3600? Reply

    I think that the 3600 is the previous gen model. The 3700 and 3800 are replacements that fit slightly different roles. Reply

    The 3700 and 3800 are the current models of the Intrepid family, whereas the 3700 superseded the 3600. Reply

    Perhaps the table should also include the Intrepid 3600 in a different colour to highlight it is the previous generation drive but then a comparison is actually possible? Reply

    Why would the endurance for the largest model drop in half? That makes no sense unless they also want to admit they are using lower grade flash for that model. Reply

    where can I buy one? I am preparing to run a [albeit strange] endurance test comparing a Micron M600, Intel DC S3610, Samsung PM863. Reply

    Dear OCZ. For enterprise drives, please make a SAS interface. Thank you. Reply
