 Posted: Wed, 7th Sep 2011 01:14 Post subject: SSD Raid0 Question |
|
 |
Does anyone know if Raid0 is possible with a dual SSD setup over Sata3 connector, and what would the read/write benefit be compared to single drive?
I have a EVGA board - evga x58 sli3 with dual Vertex3 SSD's ... so if my single ssd read is 550M what would it be under raid0 (if possible) and how would that work ... also, I have additional 4 spinners that I use for storage and curious how would I connect these in the case I run the ssd's in raid 0?
Thank you very much in advance!
fuck ...

How you connect the storage drives wouldn't change.
Running SSDs in RAID 0 is not a good idea though, because you'll lose TRIM. Intel said they were working on TRIM+RAID support about a year and a half ago, but they never released drivers. That board uses Intel's controller right?

Keep one drive for Windows and the apps you gotta reinstall on format/image restore anyway 
Stuff like Steam fits perfectly on that second SSD, as all you gotta do is reinstall the executables and it'll pick up your cache files again.

Are you actually getting those read speeds though? Run a drive benchmarking tool (AS SSD or ATTO) to double check your speeds please

Please don't, benchmarks are bad for SSDs ;p

No its not. ive had my SSD for several months and haven't lost a drop of performance.
The reason I asked him to benchmark his Vertex 3 is because he might be bottlenecked at 400MB/s read speed with his onboard Marvel 91xx SATA III controller, which would defeat the whole purpose of getting a second Vertex 3 for raid 0
So yes, please benchmark your drive before you go ahead and purchase a second drive for raid 0

Most benchmarks are bad, because they use up write cycles. Even if you don't notice it straight away, it's still a whole lot of wasted write cycles. If you benchmark it weekly, you are going to see it degrading months (if not more) earlier than it would with normal usage. "Several" months is hardly long enough to judge that. How the fuck do you suppose sites used to test longevity of these things?  |
So then he is just supposed to assume that hes getting the same read speeds as manufacturer specs??
If you look up the issue of SandForce 2200 + onboard Marvell 91xx SATA III controller (which his motherboard has), I think you will change your mind about that.
And Ive had my SSD since the very beginning of February and Ive been running benchmarks very often on this drive because I was curious to see if performance does degrade and my benchmarks are still identical to day 1. If it takes over a year or more for a 64GB SSD to degrade by a few MB/s, who cares? Hes not using it for storage and Im sure hel upgrade by then.
So yea dont just believe manufacturer specs for the drive, you gotta run your own benchmarks because you dont know if your SATA III controller is bottlenecking the drive or not

I rder a lot of stuff from newegg to my office, so when I received my first ssd I noticed that it was dropped off by DHL which was odd since packages always get here via UPS. Anyway, on the newegg website - there was a note - "dropped off at the main desk". So even tho I received the SSD i connected to newegg support chat and told them I never received it ... so they just sent me another one via ups (im going to hell hahaha) |
Yea they dont send these SSDs via UPS because the box is so small. Im wondering if I should do the same as you  But they already know that Im aware they send SSDs via DHL since I got my current SSD from newegg and also I have everything delivered to my home

According to Vertex 3 manufacturer specs, the SSD should give read speeds above 500MB/s. Heres a random Vertex 3 running on Marvell 91xx SATA III controller:
 ...not exactly in the 500MB/s range as the manufacturer specs state

I have a 120GB Corsair Force 3 coming in the mail either tomorrow or Saturday. Manufacturer specs for the Corsair drive state 550MB/S read speed but Il have to see for myself if Marvell SATA III controller bottlenecks the drive or not

If you really want to run latest generation SSD in RAID0 you should get a separate RAID-card that use the PCIe-bus.

So I received my 120GB Corsair Force 3 SSD in the mail today. A very sexy looking drive but just as I suspected it didn't perform ANYWHERE NEAR manufacturer specs. The manufacturer specs for the Corsair Force 3 state max sequential read should be 550MB/s and write speed should be 500MB/s.
Im using an EVGA X58 FTW3 board which has a Marvell 91xx SATA III controller....same controller as bxrdj has.
I ran AS SSD benchmark on the empty drive and guess what, max write speeds around 150MB/s and max read speed was at a shameful 200MB/s....This is WORSE than my 64GB Corsair Performance 3 SATA III (non sandforce based) SSD. I first benchmarked the drive completely empty, and then I removed all harddrivesd and installed only windows 7 on the SSD and still 200MB/s read speed with both AHCI and IDE modes.
So there you have it, SandForce 2200 + Marvell 91xx = shit performance. Only get SandForce based drive if youve got sandybridge or AMD setup. Im calling Newegg tomorrow morning and returning the drive for a larger capacity Performance 3 drive.

But.. most motherboards have multiple controllers, first the built-in controller (Intel or AMD, mostly 2-4 ports), then they have a Marvell controller for 4-6 more ports.
EDIT: Oh, you have a board based on X58 with the übershitty Marvell-controller. No native SATA3.
You COULD get a separate SATA-controller, but I don't know what's out there.

I mainly use AS SSD to get the sequential read and write speeds because it takes less than 20 seconds to benchmark the drive
