But then again I HAVE DONE 10 BIT UC @ 1080 50i for more than two years on this setup – yes it has been short features and ad’s only because I had 300 GB drives – the biggest at the time of purchace
That gives you about 1TB of usable space that is faster than 160MB/s (10 bit 1080 50i is around 140MB/s – just a little overhead)
THIS IS VERY SHOESTRING BUDGET WAY TO DO IT BUT IT IS POSSIBLE
thing to consider, when you do not have the budget, is backup because most likley you are capturing straight from camera (on location) on HDCAM SR deck (not that cheap to rent) to make a good use of 10bit (if you use HDCAM, DVCproHD or HDV as source then you can capture 8 bit)
My backup solution was a PC computer with linux and rocketraid running 6 disk raid5 as offline backup (backup was done weekly over gigE) nowadays you might use external FW disk or even have two sata stripe raids mirrored
good luck
