To RAID or not...that's the question

post #1 of 10
Thread Starter 
I have a OCZ Agility 2 60GB and planning to buy a Vertex 2 60GB soon and run them in RAID0.

Questions are:

1)I know that the TRIM support will be disabled if i raid. So is there any other garbage collection method avaliable for these SSDs? Will I be OK without TRIM?

2)Does IOPS rate stack up if i keep adding more drives to the array? Let's say my OCZ Agility 2 is capable of 10.000 IOPS transfer rate and OCZ Vertex 2 is 50.000. So does that mean my RAID0 partition will operate at 60.000 IOPS or it will operate up to 10.000 IOPS (maximum value of the slowest drive)?

Thanks in advance. Rep will be given for good answers wink.gif

I do like raid and i know ssd is faster but so, in future ssd will be cheap if any goes bad i do get another one much better, TRIM is good but raid is faster smile.gif its up to you.

It's all about RAID 1 for me, bro. I just like the extra security.

Best of luck, though. smile.gif

No RAID. Simply no point. You won't see a difference when going from one SSD to 2 SSDs in RAID0. I would run as two separate drives.

also, you cant raid two different drives. has to be the same exact drive if i am not mistaken.

you can RAID different drives, it will just effect your RAID size differently.

From reading people's impressions, mostly here on OCN. SSDs are already so fast that RAIDing them won't be as noticeable as going from a mechanical HDD to an SSD. Plus, I personally won't risk losing TRIM. It just works so well to keep performance top notch.

I'm not sure why you want to put these drives in RAID0, but anyway. RAID0 is intended to higher the throutput of you storage (not acces time), but since you are already using a SSD, I just don't see the point. Moreover, your motherboard only support SATA II that max out at around 300MB/s (which can be achived with latest vertex on SATA II), so there is no point to RAID0 2 X SSD on SATA II.

RAID can be excellent for write speeds. that is where the inherent weakness of all storage solutions reside, and the primary reason for RAID with both HDD and SSD.
Doubling the write speed is the main goal in this scenario. Especially your random small file performance. As i set here and type this my system is steadily crapping out small 4k writes, for logs, for drivers, monitoring blah blah blah. thousands every few minutes.
Throw in a virus scan, a media player, your email open, and a browser, and you can run into stuttering issue. Most people arent even aware that even their virus scanner is writing constantly.

RAID with SSDs is for those who primarily want to do intensive multitasking with no stuttering. smooth as glass my friend smile.gif
