Wow. Looks like a Buckaroo Bonzai title .
I’m getting a yellow space warning on my 5D populated with 10TB drives. Total capacity is 36.18 TB of which 5.41 TB is free. (5.41 TB free - whadda world. Sure, it’s 85% used but that’s 5.41 TB free. Somehow, at these storage levels, you’d think that the 85% threshold would be sort of obsolete … this isn’t deduplicated storage or anything.)
Any way, in attempting to correct the problem I’ve looked to replace drives, but at this capacity it’s getting pretty darn expensive.
I use Seagate Ironwolf drives. Amazon has 12 TB drives for $348.79, but to increase capacity I’d need $338.79 x 2 or $677.58 to yield an extra 2 TB of space. To get 4 TB I’d need $445.99 x 2 or $891.98. And the next storage bump would cost an additional $338.79 for 2TB or $445.99 for 4TB (if disk prices don’t drop) - not a terribly sustainable storage cost increment.
So … I started looking into the 8D where (for the moment) I could dump in three 4TB dries and get 12TB (until I recouped the cost of 8D chassis). Afterwards, a 10TB ($311.99), 12TB ($338.79), or 14TB ($458.79) drive would yield an additional 6TB of storage [while the latter two would set me up for a larger drive expansion cycle with a larger parity drive.
Maybe I’ll put in a 6 and two 4s and stick my Time Machine on there, though really the I/O bandwidth of Time Machine is pretty small unless you’re doing a restore. And considering how often Time Machine corrupts itself, it might not be advantageous to put it in a protected storage set.
Can anyone tell me how dependable these puppies are?
(I saw a horrific video on YouTube - though the guy didn’t appear to be a terribly competent storage guy, it still gave me the chills).
Anyone see any holes in my logic or plans?
Can anyone tell me if it works as a 40 gbps device behind a decent cable? I figure with the fairly enormous storage transfers going on to this device that reducing the transfer time even at ridiculous 20 gbps speeds might be worthwhile for a small real-time savings. (And yes, I realize that transfer speed will be dwarfed by physical drive access time, but I also realize that this uses an ARM processor which doesn’t have TB3 built in to the CPU.)
But boy are these guys huge.
Thanks in advance for any advise or insights.
