2x OCZ Vertex 2 60GB in RAID 0

Recommended Posts

Hi guys,

 

Just posting for info. I setup a System drive on my rig for Windows 7 x64 and went with 2 OCZ Vertex 2 60GB drives.

in a RAID 0 setup and all prefetch disabled and indexing to increase life. It is transferring at 530mb/s read, 486mb/s write

 

Wating for programs to open on it is no longer present, most programs are almost instant, and Photoshop CS5 opening a large 7MP image takes only seconds to load cs5 and then open the image.

 

Windows Experience Index Score for this setup is 7.7

 

Cheers

Ben

wonder how much its performance will drop over the coming months due to lack of trim

mind posting that read\write test again after its had a fair bit of use?

What does it take to get a 7.9! I mean my single G.Skill got 7.7 in ahci but its write and read was no where near that.

 

Is there some kind of trim program you can run? (I'm in a similar boat because of my raid setup I dont think I'm getting trim)

Hi guys, I will be happy to post in a few months time please note my page file is on another drive and I have 40gb free on the ssds and that's about whrere my free space will stay as I am using symlinks to link to a program files and user profile folder on another harddrive (my most commonly used apps are still on the ssds eg. Office and photoshop)

 

Cheers

Ben

Im guessing to get a 7.9 "vista wang" you'd need to use a hardware raid card.. Software is only the same score as a single drive.. I know the score is identicle with my bro's pc (single drive) and mine (2 drive software raid 0). Sux that happens, but saving yo for a proper card.. Zeb knows the good ones apparently..

I am using the nvidia onboard hardware RAID controller, no software needed. I think the whole WEI system idea is to leave the headroom for future hardware. but Its not meant to compare a guy with 1 SSD against another guy with 2 SSD's it is to compare the users hardware with there experience when buying games, so they dont need to know their system specs just the WEI number when buying a game or program from a shop. The bar (or benchmark) is raised based on when microsoft deems it so, which is why people generally score lower in 7 than Vista, surprising since vista is a dog. I dont even know if it has taken off yet, because I buy all my games through steam or Gametap usually.

he means your onboard raid is run by your cpu (thats software riad) hardware raid cards have a dedicated processor.

hardware raid cards are alot quicker than onboard raid, you have probly found the limit of your raid controller so moving to a proper raid card would net better results but they arent cheap.

Ah ok, thanks for clearing that up. I dont have any room in my 902 to put another card in anyways lol. maybe in the 6 core PC early next year

hardware raid performance is a falacy. At least it was before intel updated their raid controllers to the newer 800 and 1200mhz processors. With raid 0 there is no parity calculation so its very easy for a cpu to perform and infact many years ago software raid 0 and 1 speed over shadowed hardware raid 0 and 1 speed. Its raid 5 and 6 where things really change and the xor engine in a hardware raid controller begins to really show its healls to a cpu.

 

That said two things have changed since these comparison were made, one, we now have many core cpu's and intels raid controllers have hone from 300mhz to 1200mhz and dual core.

Can't post the WEI yet because I'm still to transfer the OS to the new SSD Raid 0, but otherwise I'm having a lot of fun with the two Agility 2 SSDs :)

Well worth the $300 I spent today on disk upgrades!

My original Vertex had TRIM support and so do these if you can believe the OCZ site :

 

"the Vertex 2 Series easily integrates into today’s mobile and desktop platforms and features TRIM support to optimize performance over the drive’s lifespan as the ultimate Windows 7 notebook or desktop upgrade.".

 

Am I missing something here? From my reading both the OCZ Vertex 2 and Windows 7 support trim, so...

 

EDIT : Doh! I assume you mean the lack of trim support in a RAID configuration :)

 

my bad!

Open a cmd prompt & Type: "fsutil behavior query disabledeletenotify"

 

If DisableDeleteNotify = 1 then Trim is turned off.

 

If trim is turned on it should read 0

Yeh - and even then, this isn't so cut and dry. As of Intel's very latest RST version, they DO support TRIM passthrough to SSD's behind RAID controllers. If said SSD's are a member of a RAID group or a parity volume however, TRIM still won't work ;).

Does Win 7 turn trim on automatically when it detects a SSD or what?

good question.

After Checking, computer says "yes" - Windows 7 has turned on TRIM for my SSD's not in RAID.

However I checked my PC with a RAID of 2x OCZ 60GB SSD drives and TRIM is not enabled on that PC.

 

Hope that answered your question.

I thought TRIM couldn't pass through the controller if your SSD's were RAIDed.

 

And very sexy. I'm keeping interested eyes peeled for the PCI-E interfaces slowly coming out. SATA just doesn't have the bandwidth for these things, even at 6Gbps. Because I need more storage I'm thinking of 5xSpinPoint F3 in RAID 5 for MOAR STORAGE. Might strap my current two 1tb drives in too if I get ambitious. Hopefully my CPU has enough spare cycles for this - honestly just can't afford hardware RAID cards (so I'll budget for one and see if I can manage without).

 

Any more benchmarks? HDTune, IOMeter etc?

This is True, TRIM does not work if the drives are in RAID, I was confirming it for the record. :)

hopefully they can bypass that lack of trim when SSD's are in RAID with the next gen of SSD's comming out soon..

to be honest unless they use a software component or a specialised windows driver to manage the disc controller, I think the ball will sit with the host(RAID) controller folk on working out a solution to use TRIM over RAID.

I could be totally wrong here, but as time passes things get cheaper. SSDs right now are pretty pricey, but I remember when a 200GB HDD would set you back a small fortune.

 

Maybe TRIM wont be so much of an issue because once a drive slows to the point of being useless, you can simply transfer the contents to another drive and turf it?

 

Like I said I could be 100% wrong. I'm just guessing.
