The crash was an F4 BSOD, similar in nature to the infamous BSOD issue from last year.

We had two systems that exhibited the BSOD, both of which were fixed by the update last October.Īs luck would have it, our own Brian Klug happened to come across an unexpected crash with his 240GB non-Intel SF-2281 based SSD two weeks ago when he migrated it to another machine.

It turns out that Windows isn't a fan of you hot un-plugging the drive it's running on, which results in the BSOD. The BSOD is caused by a bug in SandForce's power state logic that ultimately results in the drive disconnecting from the system while it's running. The results of these long term tests are folded into future reviews and recommendations. This long term testing process takes place over months. We keep track of drive behavior, including any bugs or performance issues over time. Any drive we recommend gets tossed into a primary use machine somewhere within the company. Just as background, our SSD testing is rarely over once the review goes live. Our own internal testing revealed that the updated firmware seemed to have cured the infamous BSOD. SandForce quickly pushed out the firmware to OCZ and other partners. Why it took SandForce several months to discover the bug that its customers had been reporting for a while is a separate issue entirely. This is an important distinction because although Cherryville performs very similarly to other SF-2281 drives, it should be more reliable.Īs Intel has been working on this firmware for quite a while, it's likely that the 520 uses an older branch of the SF-2281 firmware that has been updated over the past twelve months.īack in October SandForce announced that it had discovered a firmware issue that resulted in unexpected BSODs on SF-2281 drives on certain platforms.
The important takeaway is anything fixed in Intel's firmware isn't necessarily going to be fixed in other SF-2281 based drives in the near term. There are some loopholes that allow SandForce to port bug fixes to general partner firmware but the specific terms aren't public information. That exclusivity agreement likely expires sometime after the SF-2281 is replaced by a 3rd generation controller. Intel wouldn't go on record with details of its arrangement with SandForce, but from what I've managed to piece together the Intel Cherryville firmware is exclusive for a limited period of time. Intel's strenuous validation will eventually make SandForce's drives better for everyone, but for now the Cherryville firmware remains exclusive. In fact, it was some unresolved issues that cropped up during Intel's validation that pushed Cherryville back from the late 2011 release to today.

That's right, around the time that OCZ was previewing the first Vertex 3 Pro, Intel was just beginning its extensive validation process.Ĭodenamed Cherryville, Intel's SSD 520 would go through a full year of validation before Intel would sign off on the drive for release. Roughly six months later, initial testing and validation began on the drive. Still lacking a 6Gbps controller of their own and wanting to remain competitive with the rest of the market, Intel approached SandForce about building a drive based on the (at the time) unreleased SF-2281 controller.
According to Intel, the relationship began 1.5 years ago. Intel was rumored to be working on a SandForce based drive for several months now, but even the rumors couldn't encapsulate just how long Intel and SF has worked on this drive.
