If you had $500 to blow on a network storage device and HDDs...

...what would you get?

I'm thinking of making the jump to SSDs on my primary machine, and am looking to back all my media up on a network device. With a new DSLR and my amateur photographer-cum-filmmaker aspirations, this would go a long way. What would the readers recommend?

Depends? You only have $500 or just $500 for the device sans disks?

Device wise,
Can't go wrong with this

Excellent external HDD enclosure with built-in HW raid. Accessible over eSATA and USB.

It's $200 so that leaves you 300 to buy disks with. You can find some decent 2 and 3TB disks for under $100 each. Put them in, follow the directions and turn it on. Instant RAID in a box.

I think this is a quality device with lots of flexibility. You could have 4TB pretty easily for about $310.

There are more expensive devices with more than 2 bays if you really need a lot of space. OR you could take a castoff PC, add a bunch of drives to it, and run Linux. This is cheap and fast but more trouble. I think this is where dealcorn is pointing you but he didn't mention an OS.

I started with digital photography when the Nikon D70 came out, and now I have a D300. I thought I would suck down a lot of hard drive space but all of my photos are less than 200GB.

Problem with those is their just running Linux on an Atom and using fake raid. Fake RAID is BAD if your wanting redundancy with RAID-5. Works well with RAID-0, poorly with RAID-1 and absolute crap with RAID-5.

Via based mini-itx servers have better performance / electricity usage the atom. Intel deliberately crippled Atom in out of order processing.

Anyhow, the software vs hardware redundancy depends in what context your comparing it to. And it wasn't "software vs hardware" it was advanced file systems vs hardware, basically ZFS vs a RAID HBA using RAID-5/6. Fake Raid / Windows Volume management are the worst of the batch but are the cheapest to implement.

And no amount of CPU power will make fake raid-5 faster. It's the I/O calls to and from the CPU on each write that destroys performance, it makes DMA almost useless. The CPU has to task switch to perform the XOR calculations which requires a context save / load for each and every write operation, this totals into hundreds of switch's per second which basically stalls your CPU.

Best Configs NAs

The server itself ends up being ~$450 USD, the disks will run you more.

Building one of those will perform better and give you more flexibility then any store bough "NAS". Power usage is less then 40W for the server device itself.

100Mbps? Are you crazy, that's about 10MBps, you might as well be back in the 90's. You want at least a gigabit connection, that gets you about 100MBps read speed from the server. With that above array putting out 60~80 MBps in RAID-5 you should be set for data streaming.

He's going SSD meaning he won't have multiple terabytes of storage immediately available on the target system. He mentioned dealing with photos and other media, that seems to be a logical reason to move your data to networked shared storage, aka a file server.

And you'll have issues sooner rather then later. Buy cheap buy twice. Especially as your going cheap on one of the two components you NEVER go cheap on, the Mobo.

You also might want to research the Via line of CPU's better. Their frequently used in industrial / medical applications along with Point of Sale devices (cash registers) and ATMs. Basically anywhere you need a CPU that use's low power and will run in bad weather and never ever fail.

You really don't get why I'm recommending an external enclosure do you?

Firstly its HW RAID not fake raid, meaning no performance hit in RAID5. Secondly it's detachable and scalable, should something happen to the server your data is still safe and you can immediately access it by plugging it into something else. If your using onboard fake raid and something happens to the machine your data's hosed. You need an identical board to get access to it as different chips have different proprietary implementations. And lastly should you want to upgrade the server or move on to something more, you just plug the enclosure into the next system. No need to reformat / rebuild the array. This isn't possible with onboard fake raid.

No such thing.

"real RAID" is referring to a HW XOR processor that can do the parity calculations in real time while simultaneously masking the presence of the real disks from the OS. It abstracts a large HDD and tells the OS that it's real, the OS then does everything under the assumption that you have a single very large, very fast HDD. Volume Management in linux does no such thing, it's just spreading a file system across a virtual volume and adding parity calculations in there, the CPU is still doing the same XOR operations and you end up with the same DMA issues that HW "fake raid" creates. The only solution currently is to use an advanced file system like ZFS that intrinsically assumes data integrity and has it's own algorithms for determining redundancy. As that is well outside the scope of what he's trying to do, I decided to leave it out of the discussion.

He asked for a way to backup his data with protection while using a SSD. Thus I assume he's going to have it locally accessible to his PC. Since he's going to be working on this data he needs fast local access, thus I recommended an eSATA external enclosure that will provide redundancy and high performance. Large media encoding / and photoshop are what I suspect is the workload requirement.

The entire tangent on the Linux server was to demonstrate what a proper home file server should look like. Aka don't go Atom whatever you do and never use "fake raid" when you want RAID-5.
