Sata3 transfer rate/speed question???

CaNNoN_1981 · 7 Jul 2012 at 20:17

Hi ppl.

Just a quick question about something that caught my in speccy. Its currently reporting my SSD is running at sata2 speeds of 3Gb/s.

I didn't think this would be something I would need to set or change? the SSD is sata3, the motherboard is sata3 and I'm using the sata3 cable that came with it.

Is this just a false report or is this maybe a setting in bios I have missed?

Regards

It may be reporting it as SATA 2 but it's working at SATA 3 speeds.

SATA 2 would peak at around 275MB/s and you're getting nearly 500MB/s for sequential writes.

It looks like a software glitch.

You could try installing Intel RST so that you're using the Intel driver instead of the generic Microsoft one.

Version 10.8.0.1003 here (the 6.89MB file)

Version: 11.2.0.1006 here (the 12.35MB file)

The newer version 11 is designed specifically for Intel motherboards.

It may install on non-Intel boards or it may not.

Cheers Surveyor, was thinking something wasn't quite right with speccy looking at the benchmark.

You're welcome.

Try the ATTO Disk Benchmark.

I think that gives the best results for SandForce based SSDs.

Here's a guide you may want to have a look at: Sean's Windows 7 Install & Optimization Guide for SSDs & HDDs

I installed RST and it did report the drive running at 6GB/s but I encountered a previous issue again that I narrowed down to this piece of software.

I've removed RST again the issue has gone again. But so long as I know its running at 6GB/s thats good enough for me.

Results for ATTO:

ATTO result looks spot on
