Internal or External RAID5?

[Megalomaniac]

So I always have a dilemma.

Do I got for an internal RAID 5 card like a Perc i5/i6 or an external mini enclosure like this one:

I dont like enclosures because they are typically loud, you can not expand them further, if it breaks, well i don't really know i guess it's like a card, you can replace it with the same model you can still be ok?

I would like to get an 8+TB RAID 5 array. So 5+ drives.
Mostly going with 2TB drives. Ideally I would like it to support 2+TB drives for future compatibility, although in all my previous internal (in my main case) RAID array, i have never expanded and just purchased a new one, because it was time to upgrade the whole PC.

For now, my case of choice is the Corsair 600T

Good space, great ventilation, very quite, front USB 3 port. But i have some other cases in mind also.

wanted to see what you guys would recommend.

RAID 6 for the drive config.

Also, what are you doing on the array that you need 700-800MB/s throughput for?

who said anything about throughput?

I'm just going for volume. I would like to get 8TB or so (would not mind joining the 10TB club though), throughput enough to DVR a couple of shows and watch one simultaneously would be idea, but a lot of single drive DVRs offer that already.

I just started using a Sans Digital case TR5UT with Five 2TB hard drives in RAID 5.

This is not setup to do RAID 6.

I think external is better. With external, you can shut it off if you don't use it. It is also easier to move it from one system to another.

You can just set the HBA to spin down the drives after inactivity if they're internal.
