Hard drives

Which is better two identical sata hdd's in raid or one big sata hdd?  What are some of the best hdd's for about $200?  I want over 200gb for digital video recording.


Here are some I was looking at:


MAXTOR DiamondMax Plus 120 GB
Standard - Internal - Serial ATA - Rotational Speed: 7200 Rpm - Access Time: 9.2 ms - Data Transfer Rate: 150 MBps - L2 Cache: 8 M


MAXTOR 200 GB
Standard - Internal - DMA/ATA-133 (Ultra) - Rotational Speed: 7200 Rpm - Data Transfer Rate: 133 MBps

 
WESTERN DIGITAL Caviar Special Edition 250 GB
Standard - Internal - Serial ATA - Rotational Speed: 7200 Rpm - Access Time: 8.9 ms - Data Transfer Rate: 150 MBps - L2 Cache: 8 MB

I do digital video recording and my primary concern is space, not speed, especially if you're dealing with uncompressed avi.  If you do a lot of editing, then speed will be a concern, but someone just starting out won't be impacted that much by it.  I have found the most time is spent compressing to mpeg2, since even the best compressors with good quality can't do better than 1:2 (an hour of video = two hours of compression).  Go for the 250, because after a year, that will be middle of the road as far as size goes and you will want more space.
