Da Man posted : If data is in the HDD cache it will be read at 314MB/s going from the HD Tach shot instead of ~200MB/s if it was running at SATA2. That makes it about 20 nanoseconds faster. :)

Dogg posted : It's more a matter of what the OP is expecting. The standard rotational HDD cannot max out a SATAII port/connection. The drive being "SATA 3" ready, or whatever the package reads, is a marketing gimic and really only means the drive will work on a SATA 3 port. It doesn't make the drive faster. This is no different than HDD's saying "SATA I" or "SATA II" compatible.

In other words, it's normal. The drive speed will be the same connected to a SATA II or SATA 3 port as it's a mechanical limitation of the HDD, not a port issue.

I have made sure i am using SATA3 cable.

You do realize that the cable revision, does not matter here.
Maaaaaybe SATAI cable. And that's a big maybe as I believe it would still perform the EXACT same. No way would using a SATAIII cable over a SATAII cable make ANY difference.

Don't you go knocking the gold-plated Monster SATAIII cables. $100/foot.

FizzyMyNizzy posted : I am guessing why they put SATA III on the title/box. Because of couple of thing.

The Cache Memory could reach that level of MB/s even if it is for 1 sec. and The HDD controller support SATA III. Even tho the HDD Pattern + 7200rpm has a limit of read/write MB/s speed.

I also agree with Dogg. If you want to max out those SATA I, II, III port you better off using an SSD drive.

I bet you will get something like these result if you use HD Tach to bench: »dyski.cdrinfo.pl/benchmark/hdtac···8VMm.png

I sure did. So the only way to find out if i truly have no issues with SATA3 is to get another SATA3 HD installed, and than giving a test run by transferring one large file from one drive to another.

»forum-en.msi.com/index.php?topic=149225.0

Since, it only have 16MB cache instead of 64MB cache.

psafux posted : Ouch - I have a Sata II drive that has better sequential read & write performance than that.

You may want to try a different benchmark tool.. HD Tune is one example.

May want to check the firmware on the drive & on the motherboard to ensure everything is up to date.

Google to see if there are any known issues with your drive, your motherboard, and the combination of the two (im not doing that for you).

Looks like all the ports on that board are Sata 3 based on Newegg's info. I didn't research any further than that. You may want to to be certain.

does your motherboard have Sata II & Sata III connectors? Are you using a Sata III connector if so? Some boards have both..
