JulianBoolean:
There's plenty of good information already, so I'll keep it as simple as possible.
Assuming there's no issues (choking), 60 would be faster as a general rule. But under your specific inquiry, 8 disks, it would actually be better to stick with RAID 6 (faster writes than 60, but 60 would be faster at reads). As I presume you'll be writting more than reading (and reads are playback as completed files = not that much throughput is required; ie. watching a movie you just generated), go for faster write throughputs.
Getting to the specifics as far as choking, the Areca and ATTO models listed in the other thread will be fine. They're the fastest cards out right now.
Another little note, 60 is more common with relational databases, not large sequential files, which is what you'll be generating as output. So again, 6 is a better implementation for your usage IMO.
But as you're in front of the system all the time, I'd actually opt for a level 5 (still better capacity and performance, at the cost of a reduced level of redundancy). If you were away from the system, such as it being an off-site location, I'd say go for 6 as a minimum (buys you time to get a human there to replace the disk/s that have gone south).
The Areca also happens to have an Ethernet port on the back, and you can configure it to send email messages if there's a fault (keep the email open), and you'll have quick notice if there's a failure (it won't just flash a message across your screen), so you use email, or keep a browser open to the
IP address: port the card uses. Those email alerts are very handy. ATTO doesn't do this, as they have their own software utility that accesses the card, but it will also give you the information you need. But the Areca cards are cheaper (better price/performance ratio), so it's a bit easier on the wallet.
Worst case (you could learn a lot about your system), is to get the card and 8+ disks. Then create the various implementations (5/6/50/60), and test them out (real world, so use your software and some test projects). It takes time, but it will show you what your specific usage will be best served by more than any post anyone could make.
This is all presuming you do go with a RAID card of course. If not, go with level 10 and deal with it when you've run out of capacity, or it ceases to be fast enough (it will slow down as you fill the disks; happens with any mechanical disk implementation, so that's one of the reasons to go for larger capacity as it takes longer to get to this point).
It's a lot to consider, and I'd advise you take your time, as mistakes tend to be expensive.
Good luck.
