Crucial M4 / Micron C400 SSD Series Thread

[Phil]

The 4K performance of the Crucial M4 tends to be better than Intel 510, depending how you measure it. CDM is only one way of measuring it. There are many different ways.

Anandtech does it his way:

Yep, once the QD increase, the M4 runs away from Intel 510.

I disabled LPM but not Intelppm. Wil have a look at that later.

Did a test with virtual memory on and the numbers went up a little.

Just my opinion: hardware heaven gives awards to pretty much all drives..... I wonder if this is a reliable source honestly.

[Brabostaan]

Will disabeling intellppm have any negative effect on the rest of the sysyem?

[Phil]

Disabling intelppm is only cosmetic for your benchmarks. See if it improves. After that enable it again.

The negative effects are heat and power consumption.

I ignore the awards. I just look at the results.

[Brabostaan]

Right, so on real time performance I wont be noticing anything. Will leave it enabled then. System is fast enough.

Turning off Intelppm disables the CPUs ability to idle = use more power and produce more heat like Phil said

Personally I wouldn`t touch it

If I disable LPM for my SSD (boot drive). How does that affect my HDD 750gb 7200rpm (drive 2) power usage? - has music, photos, docs. Will it suck my battery quickly if i access lots of data from drive 2? Thanks
