On the Light test, the Plextor M8Pe is faster than Intel's PCIe SSDs but slower than OCZ and Samsung. The M8Pe is about 2.6 times faster overall than the best SATA SSDs when the test is run on an empty drive, and about 80% faster when the test is run on a full drive.
When the test is run on an empty drive, the M8Pe is as good as any drive at keeping the number of high-latency outliers low. The M8Pe is more strongly affected than Samsung's drives when the test is run on a full drive.
The data rates on the mixed sequential I/O test are high enough that thermal throttling becomes a factor, and the presence of a heatsink improves the M8Pe's average by 11%. Performance in either configuration is a bit sub-par for an MLC-based PCIe SSD, but it's still at least twice as fast as any SATA SSD.
Power consumption is again the highest of any M.2 PCIe SSD, and efficiency isn't great.
