I currently use an ADATA 64 GB SSD. It's awesome, and I wrote an extensive review about it (here on OCN). I've noticed ADATA's reputation increase over recent times. So far, I've had no problems with mine. ADATA actually out-performs that Samsung by ~100 MB/s write. ADATA's use a wee bit more wattage but clearly not an issue at all.
The performance is definitely better over using onboard controllers. You will end up with faster speeds, and a lesser chance of losing your array. So if security is important for you, a separate RAID controller will be ideal.
I know ADATA makes nice products, and there memory/SSD's have pretty good reputation. I just personally wouldn't trust many companies SSD's in RAID 0 other than Samsung because that's just a guarantee that the 840 series isn't going to crap out on you. While the other companies, whether they are pretty reliable, doesn't necessarily make them guaranteed. I noticed that they are faster than the Evo, actually there are a few other drives that are faster than it too that I would recommend over it traditionally (Intel 520 Series, Plextor M5P Xtreme Series, SanDisk Extreme Series). Again though, when it comes to a RAID 0 setup, I would trust the 840 Series over all of them. However, if you trust the ADATA SSD's, then hopefully you will be fine.
