At the end of the day, we need to illustrate a very important point. While the LSI 9265-8i is the fastest RAID card on the planet, it simply cannot give these drives the true justice that they deserve. The throughput of the Patriots, both in MB/s and IOPS, if they could scale perfectly in RAID would be phenomenal. 4.440 GB/s would be the highest attainable throughput!
As seen in this result with Iometer testing the maximum speed (128KB @ QD 128), we did attain the highest speed of any drives that we have tested on the 9265, a whopping 2.8 GB/s! This is the limitation of the RAID card, and not the drives.
Bear in mind that that there is still plenty of speed there that the Wildfires can give that simply cannot be utilized as of yet. The LSI card that we used simply cannot go that fast. Right now there is not a controller that can handle the sheer power of the Patriot Wildfires in this array. As next generation RAID controllers start to appear that are capable of handling the throughput of these types of drives, we hope to be there on the cutting edge to witness the unseen levels of performance that this would bring about!
We would like to thank Patriot Memory for the use of their WildFire SSDs in this, and the Areca Expander review that they were used in. We went out looking for the absolute fastest drives for our Test Bench and Patriot delivered. One of the most amazing qualities of the Patriots are the phenomenal latnecy that we experienced. You simply cannot trump excellent latency, regardless of the metric that you use for comparison.
Bandwidth is great, but latency is forever!
The SandForce controller combined with the Wildfire firmware just gave us some truly superb results. A big problem that many reviewers and testers run into with SandForce controlled drives is that it is difficult to show the true performance in benchmarks when there are different levels of compressibility of the data. Sometimes the results just aren’t indicative of that BAM! acceleration that you feel when you actually use the device. There is no method to truly measure the ‘snappiness’ factor that a user will feel when they use the drive, other than looking to the true latency of the device itself.
The excellent latency points to a truly astounding base latency for these devices and that isn’t always clear when testing with on board solutions. They simply add a small amount of overhead that masks the true base latency of any SSD. The key takeaway for base latency is that is a measurement of the true capability of the device.
A great show from Patriot, as this array was able to best every other storage solution we have tested to date!
