Hello Everyone,

Thanks to all for this great forum....

My question: What should I be checking to see why I can only get about 210-215Mb/s (HD Tune) Sequential Read on my Intel 160Gb SSD (SSDSA2M160G2R5)

My Setup:
Asus P6T Deluxe V2
i7-920 only running at 2.86Ghz
6Gb HyperX DDR3-2000 running at 2006Mhz

I am running Windows 7 64bit

In the BIOS I set the Disks to RAID.

The SSD C: drive is the OS/Boot
My D: drive is a couple older 250gb Seagates I have in a RAID/0, and getting 110Mb/S out of these drives honestly makes me quite happy.

I have upgraded the firmware on the SSD for TRIM support. TRIM seems to be working, because over the last couple weeks my HD Tune performance doesn't change. It remains in the 210-215Mb/s range

I've also downloaded and installed the last Intel Matrix Storage driver package. But should my SSD driver in computer management display an intel driver? Or should it still have the Microsoft storage driver?

Is 210-215Mb/s all I should really expect? I wouldn't think so considering all the articles on Tomshardware suggesting that with my setup I should be closer to 250-260....

So I feel like I'm missing something....

Hopefully I've given enough information here... any help is greatly appreciated.

Thanks,
Rev

Quick update... it was this article that made me question the performance: http://www.tomshardware.com/reviews/windows-ssd-perform...

I just noticed the 260Mb/s mark was with CrystalDiskMark.
The HD Tune performance averaged 231Mb/s.

So I'm about 15 or 20Mb/s shy of that. Should I be concerned? Or is that performance typical for my setup.... compared to the i7-965 Extreme and Intel MB the article used?

No. The OS takes power. And did you follow all the OS tweaking that you should do for an SSD?

OS Tweaking such as disabling Superfetch, Prefetch, etc.?

What would be good search terms to use for what you might be talking about?

Thanks!

Honestly, I wouldn't be too concerned. My 80GB is around 223 in HDtune.

And also make sure that you're keep the drive 'clean'. The first time I ran OCZ's Wiper program my MAX went up from 180MB/s to 220MB/s and the average from 110MB/s to over 160MB/s.
