That almost doubles the chances of losing data, and when you do lose it, you lose it ALL. RAID 0 isn't really a proper RAID (Redundant Array of Inexpensive Disks). I use RAID 1 with 2 WD RE4s. It, however, only protects against drive failure. There are other problems that can happen, like file system corruption, and viruses.

RAID 5, motherfucker.
That's right, I use a RAID 5 (4x 7200rpm 1TB Seagates) for my anime storage.
I use striping (2x 40GB Intel SSDs) for my OS for speedy cache reasons (and epeen).
But striping is not, as nstgc pointed out, RAID and people need to stop calling it that.
nstgc:
I'll be going to RAID 5 once I get some more money for the drives, and a dedicated RAID card (I am not doing software RAID with level 5). I had some bad experience with RAID 5 in the past. I had 2 drives drop out of an array. This time I'm making sure my drives are made for RAID and that my RAID card won't fuck up either (it was a combination of the two).
kitamesume:
which is more reliable tho, cheap hardware raid or intel's software raid, skip performance difference since its gonna be used for storage. well a dedicated real hardware raid ain't cheap either.
nstgc:
If you are using a RAID for storage, software RAID with ZFS.

Doesn't system slow down after a while, because RAID-0 doesn't pass TRIM commands? Or do new SSDs finally have a good firmware (I use now old ones Intel X-25M on two PCs) that copes well enough without TRIM?

Neither does checksums afaik. So both are crap for prolonged periods of storage.

+1 ZFS is the best FS out there, big fan. Brings enterpraise level raid controller quality with cheap HDDs, and as replacing HDDs is so easy... :D
Nothing even comes close. Altho Win 8 server will have something similar and sooner or later poor Linux will catch up with it's BTRFS. Also, DragonflyBSD has poor man's ZFS - HAMMER.

OT: seeing as next gen consoles (most popular gaming devices, most popular TV additions) will have optical mediums, they won't go away. Maybe when next next gen consoles arrive.
