Post subject:  OCZ Vertex 60G Issue
A friend of mine has two OCZ Vertex 60GB 2.5IN SATA2 Solid State Disk Flash Drive SSD
Part #: OCZSSD2-1VTX60G in raid 0. ( 2 drives )

When he benches his drives, his write times are very bad - about 50Mbps. Reads are over 200 which is fine.

I do not own any ssd's so I am unable to assist much other than to look around forums and the internet so I thought I would post here in case any of you have an idea of setting etc that he should look into. His firmware version is 1.3 as well.

OCZ forums are the place to look.

Hardware or software raid?

I'm not so sure SSD's work properly in a software raid config...

Dedicated controller?

Is it being used for boot partition AND pagefile?

Something might be eating up the buffer...

Thanks Steve-O, I have suggested that to him, but posted here on the odd chance that someone else encountered this issue and have a viable solution or suggestion.

All I know is I've seen that problem (or close to it) many a time on those forums.

Not without knowing any more info. Get him to try one card by itself.

I can virtually guarantee that this is your friend's problem:

I had the same experience:

x3 30gb Vertex (1.4 fw) RAID0
ICH10R Gigabyte EX58 UD5
Windows 7 x64

I came across a thread talking about write caching, so I went into my drive properties and saw that it was on. I turned it off and ran HDTune and was still getting ~150. I turned it back on and ran the test again and got ~600 average. This is my second Windows 7 install on the same hardware set up. On both occasions I had to do the same thing to get ~600mb/s.

*On a clean install, Windows 7 indicated that write caching was on when it was actually off.*

I came across your thread looking for intel drivers for my raid controller on windows 7 x64, but I've had not luck so far...

Hope that helps.

I'm still happy I got a dedicated RAID card.

Hey Steve-O - thank you.

I just passed that along. He is going to try it tonight. If successful or not, I will post back the results.

So much better going dedicated raid.

Oh and to answer my previous question, does software raid work on ssd's?

Software raid, as in getting windows to do it for you? Or doing it on the motherboard's built-in raid controller?

Post subject:  Re: OCZ Vertex 60G Issue
Yes, as in OS software to do it for you. Integrated raid is still hardware raid, albeit slow and inefficient...

Just remember reading somewhere not many drives support software raid config..

I've never heard of anyone even bothering to do it due to it's lesser efficiency.
