Speed Test and Raid or no Raid considerations.

[Kaspar Kallas]

this why it is a badi idea: if one of the disks fails you loose data on both.
this is why it is a good idea: you get more than on stream of uncompressed SD @ 10 bit

my recomandation would be to get yourself an external FW drive for yer system and project fails – so when something happens with yer external raid then you would only loose the media that you can recapture

if you are willing to spend a bit more than you could get yer self a swift data 200 (https://www.transintl.com/store/category.cfm?Category=2490) with the sonnet option then you would be able to add 3 extra drives to yer system so all three drives could be internal and you would have 2 slots for upgrade

I use my self the latest version – very happy with this, I have 4 drive raid0 and a system drive all inside my mac, I get @ empty drives 210+MB/s rw

Are you suggesting a 2x400GB RAID 0 is enough for two streams of uncompressed SD at 10-bit?

for sure SD pal @ 10 bit is 22.1MB/s
and SD ntcs @ 10 bit is 23.1MB/s

single sata drive should not go lower than 30MB/s on inner circles of the disk – when empty you should expect 55MB/s and stripeset almost doubles the preformance
