Raid-0 two 32gb CF cards vs single 64GB SSD?

Hello,

I've been seeing these 2.5" CF-to-SATA adapters all over eBay for just $15, which got me to wondering...

Would Raid'ing two cheap 32GB CF cards provide faster performance than a single cheap 64GB SSD?

Price-wise, the two solutions come out about the same, so the only issue is price/performance.

Any idea?

you can't use the trim feature with a raid controller, so even if the performance was matched in the beginning it would be short lived

A cheap 32GB CF card is not going to have anywhere close to even half the performance of an SSD. By the time you shell out enough money to get cards that perform well, you might as well have bought the SSD and saved yourself a lot of hassle.

Ya but be sure to get 3rd generation SSD with Sandforce SF 1200 controller like

These drives all have the SF 1200 controller but apparently the OCZ Vertex 2 has the best firmware because of an inside deal with Sandforce

This OCZ Vertex LE has the SF1500 which is supposedly an even better controller and comes with 28% over-provisioning and is designed for enterprise systems. It shows very well against It's more expensive brother as can be seen in this review

Most CF cards that aren't specifically industrial grade (the terminology is 'Fixed Disk' can't be booted in an array configuration of any kind. This includes those that can be formatted as either fixed or removable. It's really quite the pain getting any kind of OS installed on them, array or not.

TRIM doesn't really appear to make all that big a difference in the CF drive's performance. I don't know why this is, since it is supposed to substantially impact long-term performance.

I suggest just going with an SSD if you want to try a RAID config.

I've setup several laptops and media centers with 266x CF drives. Provided that you use tools like SSDTweaker, Junctions, RAMDisk and Flashfire, you'll notice a substantial improvement over traditional hard drives. TRIM might not be essential.

Are there even any CF drives that support TRIM? And does Windows 7 recognized them as TRIM-capable? I sure wouldn't assume "Yes" to either of those questions...
