Patriot Wildfire (SandForce SF-2281) 4x SSD RAID Report
We first saw the Patriot Wildfire back in June of 2011 and at the time it was one of the hottest new SSDs on the market. That was around 9 months ago so while no longer new, Wildfire is still competitive with, and considered one of the best on the market today. The key to Wildfire's longevity is the Toshiba Toggle Mode flash Patriot chose to use on this SSD.
Toshiba and their partner SanDisk has received a lot of press lately for their new 24nm Toggle Mode flash. The new 24nm flash has proven to be very fast, but that is about the only thing it's proved so far. We're still seeing issues in our labs with write performance degrading rapidly until TRIM finishes its cycle. This was not a problem on the older 32nm Toggle Mode flash, the same used on the Patriot Wildfire.
For most consumer users the issues we're seeing with 24nm Toggle Mode flash aren't going to be a big issue because the TRIM cycle is fairly quick. I've heard the WHQL spec for TRIM is around 70ms, but we've found that isn't always the case. In RAID we are still waiting for Microsoft and Intel to get their ducks in a row, so using 24nm Toggle Mode flash isn't ideal at this time. Older 32nm Toggle Mode flash is still the best choice for RAID. Given that Patriot has already announced their Wildfire SE (Second Edition) with 24nm Toggle Mode flash and a Wildfire PRO model with more space allocated to background and performance improving functions we're going to say that others have already noticed what we have with the new 24nm flash and RAID.
So even with new flash right around the corner the old flash may be a better option today for your high performance RAID needs. Today we are going to put that to the test and rock the block with some RAID performance featuring the Patriot Wildfire 128GB drives. To spice thing up we are running dual drive RAID 0 on the built in Intel RAID and 4 drive RAID 5 with the awesome LSI 9265-8i.
