Our link to Amazon is capable of 10Gig.
But you are right, I do worry about security of people's files on the NAS. Like, I would hate to have Eugenixx's adult collection visible haha.
I've looked at the amazon direct connect stuff, and while it does look good I think that unless the customer is REALLY big, they'd probably just invest more in their Internet link and get a double dose of speed.
I am only partially concerned about other people's files from a security point of view (all my stuff would be encrypted), but I am concerned about size of storage and basic SLA's. I just think it would be easier if people who bought in got given x00gb of storage, and that was it. That way I don't have to get cranky when I cant upload an archive because dan's collection of cheese pr0n has grown another 100gb.
From a realistic point of view, I think a few hundred gig would be enough for most people. If you want unlimited storage you can go pay for it, likewise if you want a few gig for some home documents then you can get a free account from dropbox.
Some quick maths:
- QNAP TS-420U is $799. 4 bay, 1RU, 2xgigabit eth ports. Only 1 power supply, but unless we want to spend ANOTHER $1400 for an 869 with dual power, 2RU, 8 bays, then its not worth it. (No, I don't think its worth it)
- 4x 3tb Seagate barracuda's would be $139x4= $556. WD Red's are $183 a piece, but I'm not sure if they're worth it.
Raid 5 would be sufficient for a 4 bay NAS given its essentially an offsite backup, so 4x 3tb drives would give 9tb of storage for $1356 ($1532 with reds).
If we went the 2RU option with 8x 3tb drives it would be $3312 ($3664 with reds) for 21tb. To be honest, I'd prefer to buy 2x 1RU kits and geographically disperse them, than have 1x 2RU sitting in one spot. For one thing, it would be a few hundred dollars cheaper straight away.
So quick price breakdown (based on raid 5):
420U with seagates = $150/tb
420U with reds = $170/tb
869U with seagates = $157/tb
869U with reds = $175/tb
To be honest if we went with the 8 bay, I'd suggest RAID 6 (allowing for 2 drives to fail), which would make it:
869U with seagates = $184/tb
869U with reds = $203/tb
So, on the basic option (1RU with 4x seagates), costs would come to something like this:
5x 1tb allocations @ $150 per allocation
8 x 500gb allocations @ $75 per allocation
Giving 13 allocations/users in total. Can easily make 18 allocations @ $75/each, or 9 allocations @ $150/each.
Based on a 4 year life cycle, it would end up costing ~$40/$20 per year.
If there is enough interest I'm happy to sort out the logistics (including initial seeding of data) and then give it to spite for racking and comms.
