My Kingston SSD says 450MB/s read/write but on CrystalDiskMark it only pulls 228 and 171

Is it defective? I'm only using it as a game storage device it is connected via SATA into the fourth SATA slot on my mobo.

You probably have it connected to a SATA 3Gbps port. That's about where they max out using the slower SATA controllers. Plug it into a 6Gbps port (if available) and Crystal DiskMark will show the increased speed.

I'm not to sure how to check if my mobo has 6Gbps

All the manual says is Serial ATA. It's a DX58SO, do you know?

Sadly, looks like your board does not support 6gb SATA

What about the eSATA, is that of any help?

Found the specs on the Intel website. It does not have any 6Gbps ports natively.

There are however add in cards that you can buy (some are pretty cheap too, like this one) that provide SATA 6Gbps ports. The maximum transfer rate is around 500MBps so it will not limit the SSD's read performance, but that 500MBps transfer rate is shared between both SATA ports on the card.

That won't make a difference. Connects through the same bus, delivers same I/O performance.

kaio37k · Nov 10, 2013

The_Prophecy :

So if I only used this one SSD it will receive the full 500MB/s read/write off that device?

My sata II drive tops out 280 R/W. Your scores are even lower then that. Have you tried updating drivers and/or bios?

The_Prophecy · Nov 10, 2013

kaio37k :

Correct. The read and write speeds will be what ever the drive is actually capable of, rather than what the interface allows as is the case right now on the slower port.

Thanks a lot for the help

The_Prophecy :

Do you by any chance know the specific name of this module? Controller card?

4745454b · Nov 10, 2013

Would be these cards.
