Micron RealSSD P400e 200GB Enterprise SATA III SSD Review

ATTO & AS-SSD Benchmarks

ATTO v2.41

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.

ATTO – Intel P67 Platform

Benchmark Results: We don’t usually see this much disparity between the read and write scores but it’s not unexpected given what Micron provides in their specifications. Actually, the surprise is that the P400e performance exceeded the specifications of 350MB/s reads and 140MB/s writes by a substantial margin. under-promise and over-deliver seems to be the name of the game at this point.

AS-SSD (1.6.4237.30508) Benchmark – Intel P67 Platform

We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from all of them.

Benchmark Results: Again we see scores exceeding expectations although the 4k writes would squarely fall in the “paltry” category of performance descriptions. looking back up at the ATTO scores, this score in not anomalous. Unlike SandForce drives, no major performance dip is seen between benchmarks that employ different levels of data compressibility.

Benchmark Results: As referenced above, the Marvell 9174 controller is data compression agnostic and therefore the graph lines trend flat.
