What would be a good choice for an external HD to provide server storage and playback of video/audio files (mix of HD/SD, and AAC and Apple Lossless) for use on a single TV?

I'm concerned about going too cheap (I found a WD 1.5TB at $105), but love the idea of the storage.

Thoughts?

I am looking at the OWC Mercury Elite-AL Pro Dual, i like it because it has a 1tb drive plus an open bay for another drive down the road, it also has a USB hub so it makes adding more drives easier in the future.

I second the OWC Mercury Elite AL single or dual drive enclosures. They even have a nice Qx line with 4 drive bays for use as a hardware RAID with an eSATA card, though the mini doesn't have an eSATA port, only Firewire and USB. A case with a Firewire 800 port will deliver the best performance with the mini (rather than USB). Do get a 7200rpm drive with a 32MB cache, though I think some models now be available with a 64MB cache. Drives marked with an *Energy label are slower, power-saving models that may not keep up with HD video bit rates. OWC usually has a selection of Seagate, Hitachi and Western Digital models at fair prices and they have good sales and tech support. http://www.macsales.com

Three questions:

Will you be recording TV to this drive, and if so, how many simultaneous streams?

Besides local playback, at that TV, by the mini, how many other devices around the house will routinely be accessing and sharing this content?

Will this drive be sitting right out with the mini, visible and audible, near the TV?

My main thought--instead of buying a self-contained commercial product, like a WD MyBook, buy your enclosure(s) and drive(s) separately: 1) it can often be less expensive, 2) give you better warranty protection and 3) it's worth being able to open up your enclosure to get at your drive without voiding the warranty.

One thing I can guarantee--however much space you think you may need now, at some point in the future you will need more. Plus, have you thought about how much space you need for Time Machine and bootable backups in addition to the space for media?

When you choose bare drives, another thing to consider is the warranty return process--some manufacturers are difficult to deal with, some, like WD, make it very easy.

I agree with both Buick and Geo, these are nice enclosures fairly priced--but I'd buy them diskless--at the moment their dual USB JBOD enclosure for $49 is attractive. Then shop for the best price on bare drives to fill it from Amazon and Newegg. ($49 is what I paid not too long ago for an aluminum JBOD dual drive enclosure with 1) hot swappable drive trays, 2) a 40mm fan and 3) internal power rather than an external brick. It's a USB AirDisk enclosure at the moment, with two Samsung EcoGreen F3 HD203WI 2TB 5400rpm drives inside.)

Sure, but at greater expense. The questions the OP has to ask are, are you doing anything that benefits from the "best performance" and is the difference in price worth it? The USB/FW400/FW800 version of that dual enclosure from OWC is $97--seems reasonable to me--if I were buying a first enclosure I'd probably go with something just like that. Firewire and Macs are still glorious together. But the second enclosure I bought would be a dual USB one.

I was a firewire and fast drive snob in the beginning, too, years ago I wouldn't touch USB with my home theater Macs and always had good luck with firewire daisychains. (A holdover from the notoriously poor USB performance on PPC Macs, I suspect.) At some point I started adding USB storage and you know what, it's very reliable with Intel Macs and works just fine for most demanding home theater tasks. The thing to remember is this--in the typical HT, you will be CPU bound before you are disk bound.

What HD video bit rates? Maybe if you plan on editing footage that you shot with your professional HD video cameras...but...

I've had 6 or so different "Green" energy-saving 5400rpm drives in regular rotation around my house for a couple of years now--over slow local USB and even slower AirDisk enclosures--and I assure you--they are plenty fast enough for playback of the "HD" video you're most likely to use in a home theater--that of broadcast HD TV and blu-ray rips. The inherent limitation is the interface, not the drive: a 5400 drive won't even break a sweat before real world USB bandwidth is saturated.

Most commercial Tivos and DVRs come with 5400 drives--and can handle recording two HD streams while simultaneously playing back content. Will a 7200rpm drive handle typical home theater stress and movement of files a little better? Yes.

But, any 2 drives in a fanless aluminum enclosure will get warm...two 7200rpm drives in a fanless enclosure will get hot and may also be noisy, which may not be a good thing if your enclosure sits right out in your living room.

Green drives, on the other hand, have lower idle power and can run very quiet and cool. So, unless your editing footage from your Red One at home for your first film school project, these low power drives can have a lot of value in the home theater--don't dismiss them due to fear they can't keep up. Drives are so mature now that you really don't have to worry.

That's a round about way to say I largely agree with Geo and Buick: for a first enclosure, go firewire--and one of those USB/FW400/FW800 models with an Oxford chipset would be perfect--but for a second enclosure, for backups and additional storage, don't be afraid to go USB or buy bare OEM drives from Amazon and Newegg, some of them Green, to save money.

For any setup, a Drobo FS is good. It is expandable and it uses a form of RAID-5. It is costly, but it beats setting up a file server with the same features.

I recently added the OWC Mercury Elite All Pro Qx2 with 4 1TB WD Caviar black hard drives set up as Raid 5. The hd's are 7200 rpm with 64mb cache. It works great for MKV storage and playback, iphoto library, etc. It is not dead silent but that does not bother me due to the location. I'm very happy with the set up.

If I can make some suggestions.... as I have been down this road many times. I have the 2010 Mac Mini a Seagate Freeagent 1TB (hooked up with firewire 800) and a netgear Nas Duo with 2 x 2TB Samsung drives running in RAID.

I originally bought the Seagate thinking "wow a Terabyte that'll be plenty"..... Nope not at all, so buy much bigger then you think you'll need. If you have it, you'll use it. The Seagate is now just there for timemachine backups btw. LOL

Once I have filled the Seagate I got the Netgear NAS Duo and shoved the 2TB drives in it. I'm now down to 600gigs and am starting to look at 5 bay enclosures. If you value your data run something in RAID. That way if a drive dies everything you have on it wont be dead. I STRONGLY advise staying away from single drives. If you do decide to go the single drive route get something with firewire 800, it is much much faster then USB. Firewire 800 transfers at a steady 800mb/s where as usb 2.0 PEAKS at 480, although you always see it advertised at 480, it's not quite true. You'll come to very much appreciate this when moving large files. The Netgear line does some REALLY cool things too if you arnt super computer savvy. Such as remote access (to get access to all your files anywhere with out the mac needing to be on), widget's to show you HD temp, fan speed, battery back up run time if you have it plugged into a compatible battery back up, etc. Really cool stuff. If you have any questions please feel free to ask, this happens to be something that I know w a lot about. Have fun!

Do a search (google) for unRaid.. I went trough this last winter/spring and ended up building an unRaid server for about $270 ( I already had a few spare drives) with a 6 drive license. I've been happy with it and recording 2 1080i OTA stations and playing a 3rd with EyeTV at the same time over gigabit ethernet. No part cost more than about $55 so in case of a component failure that is about all that it should cost.
