Can Raid-0 1st gen with 2nd gen intel drives?

I currently have 2x Intel x-25m 80gb g1 drives in raid 0.

I'm interested in adding SSD space (mostly for kicks and giggles). I've never gone below like 40 free gigs.

I am tempted to buy some new or used x-25 g1 drives for around 80 bucks each. Its very doable. I can easily run all 4 ssds in raid-0 and push 1gb/s. The intel ssds are very reliable and don't have trim support anyway so its not a big deal.

The question is, what if I were to buy 2x 80gb g2 drives? Can I raid-0 them with my 2x G1 drives?
 
should work.

dont think you will get 1gb/s though even with four drives. im on four g1's myself and top out at around 550-600 mb/s on p55 onboard raid controller.

i think even with an expensive raid controller, that 1gb/s goal is a little too optimistic.
 
i wouldn't say it's a good idea raiding SSDs of different gen or controller types. you'll probably be barely breaking 500MB with only 2 raided intel controller based drives.
 
well i'm getting around 500 with my two intel drives right now. Its actually why I don't want to just plop down for a sandforce drive (i'd get less capacity and similar performance). I thought SSDs scale pretty much linearly?

this guy raided 3 and was around 666 which is right for 3 drives....

Seems like the upper limit is 666 ish. Once you go past the 3rd drive, you don't really gain performance benefits.

I may just add a third drive to my raid and call it a day.

only the second drive is pretty much a linear gain. diminishing returns begin at the third drive and on the onboard RAID controller doesnt offer much performance past three. i went four because i needed the capacity.
 
Well I'm looking at the extreme system review and he was maxing out at 666 mb/s with his intel drives (3). He tested with 5 drives and still maxed out at 666 mb/s

I'm curious though, these new P67 boards have 6gb/s sata ports. Does that change the equation?
 
as is always the case with the intel X25 and 320 series drives... you're paying for the reliability, not the speed.
 
Seems like the 666mb/s limit doesn't apply to p67 boards that have at least 2 6gb/s ports

Refer to these 2 threads as proof
http://forum.crucial.com/t5/Solid-State-Drives-SSD/4x-Crucial-M4-128Gb-RAID0/td-p/59466

http://hardforum.com/showthread.php?t=1587502

Both threads show 4x SSD raids across 2x 6gb/s ports and 2x 3gb/s ports with excellent results on p67 boards (which I have)

Also @spikesoldier
Since your board is holding you back by around 550 mb/s throughput why not invest in cheap 15-20 dollars sata controller pcie card that can push 1.5gb/s throughput and unlock the full potential of your raid array?

Of course.

I did a RAID0 with one of each but that's not really the point.

You can RAID0 2 different drives but they will work at the speed parameters of the slowest drive.

The G1s and G2s were basically the same but the G2s had TRIM.

You'll have no problem but you may run into the chipsets speed cap.
 
My setup was raid 0 sandforce 240gb drives.
Corsair force GT.. Very happy to break the 1000mb barrier.

Not sure if you understood what I said there? Use RST to activate write-back cache.. OR.. go into the storage controllers in device mgr and set the disk drive/properties to active caching by.. unchecking the caching option>click ok>recheck>click ok. It's now active.

The issue with that setting is that it's always checked by default but is not actually active by default. That's why unchecking/rechecking with an OK in between will activate it.
 
I will try the RST not installed so have to install it.
Thanks. I will update chart when done.
I thought it might not be a hot swap thing and would need to be done when the arry was created like block sizes would be.
