Best Solutions For Massive Home Hard Drive Storage?
i_ate_god writes "I download a lot of 720/1080p videos, and I also produce a lot of raw uncompressed video. I have run out of slots to put in hard drives across two computers. I need (read: want) access to my files at all times (over a network is fine), especially since I maintain a library of what I've got on the TV computer. I don't want to have swappable USB drives, I want all hard drives available all the time on my network. I'm assuming that, since it's on a network, I won't need 16,000 RPM drives and thus I'm hoping a solution exists that can be moderately quiet and/or hidden away somewhere and still keep somewhat cool. So Slashdot, what have you done?"
How much data constitutes "massive"?
..., are the movies you download compressed at all? You say you run out of slots, how big are the drives you're putting in the slots? Personally, I let Netflix do the storing for me. I have a few TB's but never come close to filling it up.
The only caveat about that particular solution is the lack of redundant power, poor serviceability in the rack (may not apply like you said), and slow speed.
Their solution achieves the density it does because they are using SATA multiplexers, but that effectively creates bottlenecks and lowers overall speed. It works for BlackBlaze's application requirements, but YMMV.
Protocase.com makes the enclosure and will sell it to you for a pretty reasonable price. Getting all the parts is not such a big issue. I think we estimated we could build one without drives for less than $3k.
If you don't have it in a rack, then serviceability will be a lot better for sure. Rackmount solutions require cable management and heavy duty slide rails, and wide aisles, in order to gain access to the drives. The backplanes are parallel to the ground, facing up, and require taking the top off to access. Not exactly IT friendly.
Since the person in the article is not using this in a datacenter, cooling is going to be an issue. I suspect BackBlaze survives due to hot-cold aisles and plenty of airflow. Sticking one of those enclosures in a closet without ventilation/cooling is a recipe for disaster.
I looked at a Drobo - but being on a budget, I kept on looking elsewhere. I don't doubt they deserve those reviews, but they are not cheap. And if the Drobo itself dies... good luck getting the data off those drives without another Drobo handy.
You gave a bunch of links which require wading through hundreds of lame arguments, including 100 different people proudly proclaiming "RAID is not a backup solution". Nobody wants to read that shit.
