two disks = RAID 0 or 1
RAID 1 is mirroring:
- Pros: safe (goes on even with a dead HD), fast reads (from both disks)
- Cons: you only use 50% of total HD space (500GB total in your case).
RAID 0 is stripping:
- Pros: fast reads/writes and you use 100% of total HD (1TB)
- Cons: unsafe (you lose 1 HD, you lose everything).
Or just don't use RAID and create a cache_dir on each HD...
Best would be RAID1 for the system and no RAID for the cache_dirs I think.
