He already has 4, not 2. With that he could run a 222Gb RAID5 array. Although RAID5 has more capacity than a RAID0+1 or RAID1+0 array there are performance penalties, particularly if it is software based RAID. RAID5 can also only handle failure of a single drive; a 4 drive striped and mirrored array can handle a single drive failure, plus an additional failure if it's on the right "side."
BTW RAID0+1 and RAID1+0 are not the same thing (your topic says one, the text says the other...) The latter is better because it mirrors then stripes, which means less work if a drive fails.
In response to the original question, if the drive geometry is identical then you should be fine. Ideally with RAID1+0 you would have one set of 8Mb drives as the first mirrored pair, then the other 16Mb set as the second. If your controller doesn't visualise where a physical drive appears in an array then I'm guessing that plugging in the drives in 8Mb, 8Mb, 16Mb, 16Mb order should work. This is with RAID1+0, with RAID0+1 they would need to be alternating.
