RAID? You need at least 2 hard disk to do a RAID, right? If I'm correct RAID basically sum up multiple physical hard disk to a single logical unit with having RAID-0 - 6 as options that you can select like if Raid 0, one of your hard disk kaput, your whole RAID is kaput, but if Raid 1, either 1 kaput still ok since it just mirrors back whatever from HDD0 <-> HDD1. Other RAID numbers I'm not really sure~
Anyway, played Assassin's Creed Brotherhood finally on my Sager NP8130. Damn awesome, no lag at all.

maybe should try Portal 2 next

Some RAID may required at least 3 HDD or more to achieve the redundancy level.Anyway, played Assassin's Creed Brotherhood finally on my Sager NP8130. Damn awesome, no lag at all.

RAID-0 (Just Striping with no mirroring or parity block) - minimum 2 or more HDD, gain in IOPS performance, but if any of the HDD failed, everything is gone.
RAID-1 (Just Mirroring with no striping or parity block) - minimum 2 or more HDD, for redundancy purpose, no performance gain, and you can only have total (HDD space / 2) of disk space.
RAID-5 (Striping with distributed parity block) - minimum 3 or more HDD, the cheapest redundancy solution, good performance in reading, but slow in writing as it needs to do parity block calculation before each writing.
RAID-1+0 - combination of RAID-1 and RAID-0, minimum 4 HDD and must be in even set of HDD, has the performance for read and write as well as redundancy. Similar to RAID-0+1, just different by it creates a striped set from the mirrored set.
RAID-0+1 - combination of RAID-1 and RAID-0, minimum 4 HDD and must be in even set of HDD, has the performance for read and write as well as redundancy. similiar to RAID-1+0, just different by it creates a stripe set as primary, and then mirrored over to a 2nd stripe set.
Hope the above help.
