Force GT 60 GB pathetic read/write speeds

[wildhorseau]

I hoping someone can suggest what may be wrong here.

1 week old SSD windows7 pro 64 bit & have installed all my usual programs.

SSD in in AHCI mode in BIOS

running on sata1 port

1 week old & already has latest firmware

 

IE temp files are on D: a storage drive

FireFox cache is also on D:

 

It is stated that this drive is 555 MB/s sequential read — 495 MB/s sequential write

After testing with crystaldisk & ATTO Disk Benchmark I get the pathetic speeds as shown below.

ATTO Disk Benchmark

Why is this disk running so poorly. $150 AUD for this I paid & getting pathetic speeds.

I hope someone can shed some light on this for me.

The MS Windows Experience Index rates the drive at 7.6. But I am far from impressed at the speeds I have found this drive to be running at.

Please help

 

Thanks in Advance

 

As a comparison, I ran the same benchmark programs on my old Performance Series P64. With basically the same programs as on my GT SSD

First, you have SATA II ports, not SATA 1 as you stated above. Second, you'll only hit the advertised speeds on an Intel SATA III port. SATA II maxes out at around 280 MB/s. Write speeds are probably being slowed down by the OS being on the same drive.

I guess he meant "first SATA port".

 

 

But right, you won't get the advertised speed with SATAII, upgrading your mainboard to a model with native AMD/Intel SATAIII controller would be recommmended.

I appreciate the feedback.

yes I did mean the 1st sata port. oops, bit of a typo there.

My motherboard is Asus Rampage II gene all sata 3.0 ports.

reading through a post somewhere on this forum I found the MS fix it trick to get it running in AHCI, which it now is.

 

if anyone has any more ideas, I appreciate it.

 

Where I got my SSD, the guy was trying to get me to avoid buying a corsair SSD, but I stuck to my guns & stayed with Corsair, as I have never had a problem with anything Corsair untill now.

 

thanks in advance

To be clear, you have 3.0 GB/s ports which are SATA II. SATA III are 6 GB/s. You do not have those ports. Your motherboard is your bottleneck.

appreciate the reply wired...

maybe time for a new board then...:D:

time for some research on a nice new asus board. Any suggestions of the top of your head?

 

CHEERS

Like Wired already said, you don't have the appropriate type of controller. A new mainboard with native Intel controller would be the best (e.g. P67/Z68 chipset). There are some SATAIII PCIe cards with Marvell chipsets, but they are not recommendend (won't achieve full speed) and the Intel SATA PCIe cards are much too expensive (400+ USD).

 

Anyway, using SATAII won't be such a big issue, I guess you won't recognize the difference to SATAIII unless you benchmark your SSD or read/write large files from/to your SSD freqeuntly.
