Odd one, RAID0 Intel 330 performance same as single disk?

MasterPlan1 · 1 May 2013 at 23:31

As the title says, I've just rebuilt my laptop with another 330 creating a RAID array, restored from backup and... I'm not impressed, only getting 527.7MB\s on reads where as I was expecting near double that.

The only thing I can think of is I set the stripe size too high at 128K?

Ideas?

Is that similar to the speed you were getting with a single drive?

Does your laptop have a SATA 3 interface?

Yup, it's a Clevo W350ETQ, all ports are on the Intel controller.. And from what I recall, they are exactly the same speeds as a singular drive.

Here's RST,

(In case anyone thinks anything is funky going on with the restore... It wasn't a restore per sé, I did a USMT & OSD... It's nice having SCCM at home

Click on the advanced option for each of the two SSDs and check it says SATA 6 Gb/s.

And we have a winner, obviously the 3rd port where CD-ROM would be is a SATA2 port... I'll flip the 1Tb and the other 330 around.

Update us with the results when you've done it.

Not too shabby, the previous results I've seen on these laptops with raid have been with Sammy 830's which got better results, the 330's can go a bit better when done on a desktop board though it would seem.

But, for a £60 upgrade, pretty decent boost, will make the VM's fly a bit faster.

I'm glad it's sorted.

Enjoy
