Been tinkering with my new Crucial M4 and scores seem to indicate SATA-II speeds rather than SATA-III. I read our M17xR2 "goes up to" SATA-III. I read a few SSD scores here and they are twice what I got but most of these are Intels and not Crucial.
I've tried both ports and get the same benchmark numbers. It's on 009 firmware, fresh install of windows, fresh drivers, some windows tweaks, etc but nothing changed. So now I'm curious how you guys got so high on your scores and what else I can do to get mine that high. I'm using both Crystaldiskmark and AS SSD benchmark and get the same results.
If I run out of options I'm going to have to return the M4. There's not point if I can't get the optimum speed out of it. My old SSD will do just fine in this case, although half the space.
Please share your experiences and advice as I think I'm out of options to move further in getting higher numbers. A clear mind is needed here I think![]()

I have an R3, not an R2, but my 128GB M4 (FW0009) gets a crystalmark of:
Seq 479.6 196.9
512k 362.7 179.3
4k 23.33 44.68
QD32 312.3 179.2
It definitely looks like you're getting sata2 speeds there.
Is the drive set for AHCI or RAID in the bios or something else? if it's not AHCI or RAID that could be the problem. -
here's mine

I though the R2 was only SATA2?
-
Nayilalien, are you running bios 0009? Your 4k scores look substantially lower than mine (e.g. QD32 write 13.71 vs 179.2).
Tostito, I just looked and according to dells specs sheet for the r2,
Hard drives
two 2.5-inch drive bays supporting:
• SATA-II or SATA-III hard drives
• Solid-state hard drive
So he should be able to get sata 3 speeds... -
Yea i'm running 0009 firmware. I'm clueless as to what I should do about it. -
The ports itself are SATA2.
You can use a SATA3 SSD but the SATA2 port wil limit it to SATA2 speed if I'm correct. -
Yea, the problem is the spec states SATA2/3 drive support but I don't think it can achieve SATA3 at all. I think I've done pretty much I can in tweaking to get higher numbers and this is it. While my old SSD got a boost of around 30MB/s from the tweaks the M4 hardly gain anything, including the firmware. That is why I'm suspecting the R2 ports rather than the drive.

0009 firmware
while AW M17xR2 is based on PM55 chipset it has no sata III support. Also to extend the life of your SSD try to run at least 3x100mb test and not 5x1000mb ones using crystaldiskmark) the test itself runs faster as well, lol -

R2 will only run at sata II speeds.

That's why 4k random speeds are low -
If you really want to see cores through the roof, go into File, Test data and select 0x00.

One other possibility if all other things seem to be ok is that you have a defective SSD -

Remember though Nayilien, the OP has a r2. not an r3. And its apparently limited to Sata II speeds.
