I'm researching my next storage upgrade and have a few solutions in mind.
Currently, I have a first generation 1TB TeraStation NAS external box with 4 X 250GB HDs. It's still up and running fine and has done it's job well. I've seen the new TeraStation design and it looks like they've improved quite a bit on the original.
Benefits of original Terastation
-NAS: its own network access device so is always accessible to any PC on the network if it's turned on.
-built in RAID
-4 USB ports to add more hard drives (sounds nice but never used..kinda like that 2nd SLi slot!)
-gigabit (faster than USB 2 or Firewire 800)
Negatives of original Terastation
-poor design for adding and removing hard drives
-not as fast as eSata
With that in mind, I'm debating between a few options for my next mass storage.
What it has to have:
-4 or 5 HD capacity
-eSata
-easy to Hot Swap drives
RAID isn't important.
Some things to decide between:
-individual eSata connectors, or
-multipath (single connection for all drives)
-external enclosure or internal 5.25 x-bay
The easiest hot-swap external (and internal) design I've found so far is the I-Rack Quick Swap. With this system, you don't need to mount the hard drives to a tray before hot swapping them. Very nice:
The external four bay version runs $249.00, internal single: ~$30.00
I'm thinking of using SATA drives as a storage medium the same as most people use DVDs or CDs currently and just hot swap them when needed for things I don't need access to all the time...like eventual craploads of HD movies, TV series, etc. With 500GB drives in the $100.00 range and dropping, this is the cheapest form of storage with the quickest access. (takes seven seconds for windows to recognize a hot swapped drive)
The individual docking stations are less than $30.00 so it might be nice to put one of these into a 5.25" drive bay anyway and use it to swap out OS drives when playing around with other operating systems.
The external version of this comes in two varieties. One that has eSata conections for each drive and another that has the mulipath solution. I'm thinking individual eSata ports would allow me to route drives to more than one PC if I wanted to.

Another option is an internal hotswap option. AMS makes 3,4 and 5 drive configurations that fit into two or three 5.25" drive bays.
Here's the four drive:

And the five hard drive version:

Pretty amazing to fit 5 hard drives into a 3 x 5.25 area.
I could swing that as I only have one DVD drive in my 4 x 5.25 bays. The problem is that I can only have a total of six sata devices and already have 2 internal HDs so five more wouldn't work. Also internal = sucking power of PC's internal power supply. I think if I went internal, the four drive version would work best. Plus it has individual power buttons for the hard drives so I wouldn't have to keep them cranking along all the time wasting power.
For these, the four drive version is $109.00 and five drive $119.00 so they are very reasonably priced.

I'm thinking maybe getting a single no-tray hot swappable 1 x 5.25 internal mount and then the four drive no-tray hotswappable external drive enclosure. ~$30.00 and ~249.00. I'd leave a single "permanent" HD in my main PC and then not replace the internal HD that just died. I'd then start buying 750GB HDs @ $200.00 each (no rebate required when on sale at Frys). I'd probably only get two 750's to begin with and then three 1TB drives when they drop in price later on.
Eventually, not counting the permanent OS HD, I'd have 4 X 1 TB in the external enclosure, one 750GB in the hot swap 5.25 drive bay, and still have the 1TB Terastation for the network at all times, leaving an extra 750GB drive to play with OS's on that could be popped into any of the hot swap bays internal or external.
All that would get me about 6TB of storage always active with the ability to hot swap other drive as well as easily hot swap up to larger capacity HDs as they are released in the future. It may seem like a lot but I constantly delete masses of data to stay under 1.6TB now. I'm not trying to go for some sort of record or anything, it just seems storage requirements keep going up and I want to be in as painless a situation as possible for adding more of it. A lot of it has to do with taking a HTPC approach to home entertainment now so the PC will be serving up the movies, etc for the main projector screen with HD content gobbling up space rapidly if/when I start saving more of that format.
I really like the idea of being able to buy an OEM HD and just be able to shove it into a slot and be ready to go with no case install work or tray mounting needed.
I'm still looking but those are the leading contenders so far.
I'm Interested in other thoughts. I'm not big of raid at all for data protection or speed. I'm happy with the speedy 7200.10 drives or, maybe down the road another, Raptor for the OS drive. The amount of data that is truly irreplaceable is so small it can be copied to every drive if needed. Everything else can be had on the newsgroups for the most part! Some stuff that's replaceable would be a pain to get back though like my scanned comic collection. It's all easy to get but to get it all would take a long time on DC++. MP3's, even tens of thousands of songs, I could get back in a day or so on the newsgroups at a rate of ~1,200 songs an hour. if something ever happened to the newsgroup gravy train, this storage business would get a lot more serious.

1st gen 1TB drives are already down to
$389.00 but I wouldn't recommend those five platter Hitachi drives. Better 1TB drives are right around the corner.
