In general, the class of device you describe would be called network-attached storage, NAS for short; the specific use case you describe can be filled by any number of home- or small-business-grade devices of that type.

You probably won't be able to max out this rig on the CPU side for a single video, because video encoders aren't embarrassingly parallel (i.e., able to scale to as many threads as you have). You would be able to max this out for sure if you had a few simultaneous processes going on.
Unfortunately there's not much you can do to get a single video stream to ...

See this article: http://augmentedtrader.wordpress.com/2012/05/13/10-things-raid/. Here are some snippets from that post.
Software RAID has advanced significantly in the last few years (as of 2012). Hardware RAID still has the three key vulnerabilities it has always had: First, it is expensive. Second, if your RAID card fails, your RAID volume fails; it is ...

Ideally, you want the exact same model, with the same firmware, size, speed, etc.
However, you should be able to get away with any drive as long as it is at least the same size, or bigger. Obviously, if it was smaller, the RAID would not have enough space. I have seen RAID controllers complain about "non-RAID compatible firmware", but the ones I have ...

Do you know the size of the individual HD's? You could derive it from that
With RAID 1, the total size that you see in windows will be the size of a single disk (the smaller one, if they differ..)
With RAID0, you will have the sum of both disk-capacities (or twice the size of the smaller one, depending on RAID implementation..)
This is assuming you use ...

First, determine the value of the data. If this is business-critical data that you have to have, evaluate your options with respect to sending the disks to a professional data recovery service. Self-recovery from dying disks and crashed RAID arrays is always a bit off the edge of the map. If you're already assuming that the data on the old drives is lost and ...

If you are going to use FreeNAS then why not just use ZFS. It is the simplest way at that point. I have a media center that I started in 2008 and have been slowly expanding it. I started with external USB drives that were setup in Raid1 and then moved to NAS drives that backed up to the USB drives. I finally moved last year to a dedicated file server ...

There are no dependencies in the kernel between swap partitions or files, only a low-level mapping of pages within each swap area. Reading pages from swap is a low-level read of several contiguous sectors from the disk. So if one swap area fails, the others are not affected.
If a swap partition fails, no one will notice until there is a hard page fault in ...

There isnt enough information to say what happened. But it sounds like you had a catastrophic failure, like a power surge. It could be the drives are damaged, or the RAID controller itself. RAID protects you from the loss of a drive. However, it does not protect you from corruption. Nor does it protect your from the loss of multiple drives (depending on ...

There are such devices. Basicly they are multi hard drive enclosured with RAID.
An example is from icy dock.
It has not network port, but USB, 1394 and eSATA connection options and is idependent of the computer. It is meant more for desk top use, but can easily be transported.
There are many vendors but you could start by looking Newegg icydock raid ...
