How long until we see the first petabyte hard drives?

~28TB onsite at the NOC to another of our locations connected via
4x10Gbps fiber to an identical box for mirroring.

All of my hypervisor machines and guest xen PV and HVM machines
are now on fast SSDs... The on-site backup server is still RAID10
HDD based for $/GB reasons, it doesn't need fast throughput, and
its twin offsite machine is also HDD based.
Interestingly for many 'enterprise' applications you don't need
that much disk space at all, if things are set up right. So you
can use expensive and high quality SSDs. Example, the
Sugar/SuiteCRM VM has 20GB of disk total allocated to it and is
using maybe 4GB of that, of which 85% is the operating system itself.
I remember buying a 240GB Intel SSD for $1/GB three years ago for
my laptop, and thinking that was great. Now a Samsung 850 Evo 1TB
is nearly the same price.

I'm about to move all of my arrays to SSD in the next few

I did just build a new NVR, but it's raid10 HGST 8x2TB.

Yeah, I agree. Unless it was for video editing temporary
disk space. Or a setup like Backblaze's storage pods where
data is redundantly stored across multiple unique machines.
I wonder what the rebuild time is if you set up an array
like seven 10TB in mdadm RAID6 and an eighth drive as
hot-spare. 18 hours?

I would be terrified to run anything but raid10 on those.

As compared to the 6TB price which is about 4.3
cents per GB:

10TB:

It's about 7 cents per GB... Price is high so far,
but if you need a huge amount of storage in a
small space (like a 1U server with 4 x 10TB + 1
boot SSD on motherboard), can be worth it.
