G.Skill Phoenix Blade (480GB) PCIe SSD Reviewby Kristian Vättö on December 12, 2014 9:02 AM EST
AnandTech Storage Bench 2013
Our Storage Bench 2013 focuses on worst-case multitasking and IO consistency. Similar to our earlier Storage Benches, the test is still application trace based – we record all IO requests made to a test system and play them back on the drive we are testing and run statistical analysis on the drive's responses. There are 49.8 million IO operations in total with 1583.0GB of reads and 875.6GB of writes. I'm not including the full description of the test for better readability, so make sure to read our Storage Bench 2013 introduction for the full details.

We are reporting two primary metrics with the Destroyer: average data rate in MB/s and average service time in microseconds. The former gives you an idea of the throughput of the drive during the time that it was running the test workload. This can be a very good indication of overall performance. What average data rate doesn't do a good job of is taking into account response time of very bursty (read: high queue depth) IO. By reporting average service time we heavily weigh latency for queued IOs. You'll note that this is a metric we have been reporting in our enterprise benchmarks for a while now. With the client tests maturing, the time was right for a little convergence.
Quite surprisingly, the Phoenix Blade takes the lead in our 2013 Storage Bench and even beats the XP941. After reviewing the RevoDrive 350, I didn't get my hopes up for the Phoenix Blade, but it looks like G.Skill has done a much better job at optimizing the drive for performance.
