so when buying SSDs for a Raid 0. What should I be looking for?
Just make sure it's not actually a box of termites running around chewing your data into a piece of wood.

Looking to build an internal SSD RAID 0 (2 drives):
1) Faster response from sleep/inactivity
2) Faster boot times
3) Transportability, better protection against data loss and drive failure.
What SSDs are reliable and fast? Do I want to avoid SANDYBRIDGE chipsets? Why?
I thought about doing what Jeff Kilroe does, 4 RAID 0 7200 RPM drives. The bottom line is I have an Apple Raid Card with SAS 15,000 RPM drives and I need the extra spot for a Rocket X card.
Thanks in advance for any advice.
As Jeff suggested earlier simply stripping (4) 2TB Drives as an internal Raid 0 will give you great performance and 8TB of local storage. I use this setup in all 3 of my Mac Pros.
What's your bootup time? Do you have delays from wake mode?
We've tested a lot of different models and we've standardized on either the OCZ Vertex 450 drives, or the Samsung EVO units (the PROs are okay too). The best thing about the Samsung EVO line is that you can get a 1TB drive from around 70 cents per GB.I use 256GB Samsung 840 SSDs as my boot drives. I'm running 10.8.4 and my systems are pretty responsive. What are you using right now as your boot drive?
Got the PM Will. Pretty much what everybody here is saying. The Samsung's seem to pretty popular and perform well. Used one pretty recently. If the pure goal is fast application launch and start up that's pretty much what you'll get with this.
We had some Seagate enterprise class SSDs through here not long ago that was pretty great. Gotta look up the model on that, but it was used in a larger array of drives.
Remember though if it's booting up a program and say loading up 2200 clips into a bin or something, while the program will launch quick the drives and other I/O bottle necks will get in the way if the media is coming from something slow.

Both brands are very fast and have very high MTBF and repeated Read/Write cycle ratings.
BTW - my personal Mac Pro systems (4,1 and 2,1) have 4 Seagate Constellation ES.2 and ES.3 drives striped and they're bloody fast. My rMBP just got a new striped array of 4, 512 Samsung EVO drives via Thunderbolt. 812MB/sec W/R - Zoom!
No need for SSD RAID-0 here. You really won't gain anything.
I would avoid any SSDs that use a SandForce chipsets (not Sandy Bridge, that's an Intel CPU architecture).
I use external RAID-5 / RAID-6 setups for larger storage, but the RAID-0 as primary workspace within the Mac tower just can't be beat and it's super cheap. If you're running such an array in your Mac, make sure you don't allow the system to put HDD's to sleep. The drives can sleep if your system does, but not on your own. You'll find that becomes a real hassle at times if it puts them to sleep, then they all have to spin-up and sync. ugh.
I still don't get why you want a Raid 0 SSD array for your MacPro. A single 256GB Samsung 840 as a boot drive will give you plenty of performance for the price. Trying to put two 512GB or 960GB SSDs together in a Raid 0 stripe seems like complete overkill.

There's always the Fusion I/O PCIe SSDs to consider as well. These give the best performance. They're not really much faster than what's out there in SATA form, but they have amazingly solid sustained read and write performance. The down-side is cost and that they take up a precious PCIe slot.
