Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0 x64.
A fantastic set of results for the Crucial M4, scoring over 410MB/s in the sequential read test and 238 MB/s in the 4k QD32 write test.
With incompressible data, the Marvel controller inside the Crucial M4 powers out way ahead of the Sandforce 2281 drives.
When compressible data is enabled via the ‘oxoo fill' setting, the performance of the Sandforce drives outclass the Marvell unit (see 3 images above). The scores for the Crucial M4 256GB don't change much, if at all, with this setting enabled.
Im curious, and no one has ever explained this really well, when would compressible and incompressible data make a difference, isnt ‘windows’ code all compressible data regardless?
Sandforce is really in a league of its own right now.
I always liked crucial, their website is great too which has helped my family in the past when they are looking for upgrades. the scanning capability.
Rumors right now that Sandforce 2281 has some quality control issues, until this is cleared up this might be a better bet. always had a problem with sandforce quality control. Crucial will never have that problem.
Intel and Crucial just cant compete with SF. they are miles ahead.
I agree, a small price drop would Be a good move for crucial
Sandforce is great but this is a good option, just not quite as quick, most people wouldnt notice
Chances are you are using the Intel RST 10.1 drivers (and/or earlier versions). It is buggy when used in conjunction with the M4 and particular firmware because of a buggy Link Power Management setting that is enabled by default by Intel. This is most apparent by the no-score for gaming in Vantage. This Intel driver issue “will” also adversely affect other M4 benchmark scores, even when it’s not readily apparent.
There are four ways to fix it that I’m aware of:
1.(this one worked for me in lab troubleshooting before I knew it was a LPM driver issue) Go into device manager and change to MSAHCI driver, reboot, and then change back to Intel RST driver and reboot again.
2. Upgrade to latest rev firmware
3. Manually edit LPM registry lines. You’ll have to look up the exact registry enries as I can’t remember them off hand.
4. Use Intel RST 10.5+ driver versions (available from numerous sources, but probably not WHQL certified yet).

This is late in the game, but I fail to see the “clearly ahead” of the C300 proof when you are comparing a 256G C4 to a 64G C300… the smaller drives are significantly slower than the larger ones, so this is truly NOT a fair comparison. I hope you are comparing apples to apples in current reviews, but I arrived here mainly hoping to find a comparison of the C300 to the newer M4.
Thanks,
Its a very old review Jack. there are much more indepth comparisons now in the SSD reviews.
