Is this pc spec good enough?

[hhv_pro] “I’ve had yet to see an affordable (unless you are talking about dual Fiber Optic types) Raid config that can deliver uncompressed full HD in other then Raid0.”
Maybe you didn’t look in the right place. Uncompressed full HD is only 1.485 Gb/s, any decent 8 or 10 disk Raid5/6 array can easily handle that and the total cost is no more than $ 1.800 for a ten disk array with 5 TB of storage with a top-of-the-bill raid controller.

Are we talking about 275MB/s sustained, which will require at least 20% headroom, or around 315MB/s? (for 12-bit 4:4:4)
Please post a link, I would love to get my hand on something like this!
Thanks

Like Harm says, you’re behind the times. The newest Sata3 controllers, particularly Areca, are blazing fast and efficient. But Harm’s $1.8k is a little too optimistic just now. It’s closer to $3k for a top flight, quiet 12 drive (w/500 GB drives) BYO Raid 6 system that’ll give you 5 TB of double protected Raid storage. A system like this will do 2 tracks of uncompressed 10 bit HD, all day, and 3 tracks in a pinch.
See this thread that lays it out in detail although drive prices in particular have come down a bit since this system was built:

Thanks!
This is great info! So with this Data rate I would stick to Raid6. -
HHV,
[hhv_pro] “So with this Data rate I would stick to Raid6”
Ask the author and builder, David Cherniak. He’s using Raid 6 which uses 2 drives for redundant data which is double safe because 2 drives can go down at once without lossing data. Or you could use Raid 5 which uses 1 drive, enabling 1 drive failure. This would make the raid slightly faster and give you another 1/2 TB storage to work with (assuming 500 GB drives.)
