Crucial M4 SSD Firmware Update (0009) Posted – Tests Display Definite Performance Increase

This is direct from Crucials note to us:

Increases…

  • sequential read speeds by up to 20%
  • PCMark Vantage benchmark scores, which results in an improved user experience in most operating systems

Improves…

  • throughput performance
  • write latency for better performance under heavy write workloads
  • compatibility with latest chipsets
  • intermittent failures in cold boot up related to some specific host systems

Provides…

  • users with faster boot up timescompensation for SATA speed negotiation issues between some SATA-II chipsets and the SATA-III device

We thought it only fair to show you first hand what we are seeing. We tested our Crucial M4 128GB SSD before the upgrade (left) and then after we applied their new ver. 0009 firmware (right). All tests conducted are fresh results and were done within an hour.

Generally new firmware is making sequential read transfers higher but some users were complaining for lower random write transfers and slower access time for writes.
In my case sequential read on single drive is higher but all other transfers are almost the same +/- 1-3%. When I set raid then some results are worse than on 0002 firmware and sequential read is about 20MB/s higher in ATTO or AS-SSD.
It's only on AMD controller but maybe it's working better on Intel that I didn't check.

So max sequential transfers in ATTO I are about:
Single drive - 560/115 MB/s
RAID0 - 750/235 MB/s
on 0002 was:
Single drive 460/115 MB/s
RAID0 - 720/235 MB/s

it's for 2x M4 64GB on AMD SB950
