[citation][nom]mousseng[/nom]Hm. What's different between RAID0 and BIG mode?[/citation]
RAID0 splits data evenly across drives without redundancy. It is very fast, but in case of drive failure, you lose all the data.
BIG mode is simply uniting all physical disk so they appear as a single unit.
Keep in mind SSD's already has a fast read/write speed so the RAID 0 is pointless, especially it will just be capped at the max USB3.0 read/write speed (Duh?). SSD's also has a 100+ years life and hardly breaks or file corruption, what's the point of RAID1 mirroring? Why would I spend big money on larger size mSATA SSD's, to mirror them when they already last forever?
Word of advise, make one that supports 2.5" SSD and ditch the RAID support, then you may get some sales.
