You guys have given me some great feed back. Thanks!

Another question. As I try and configure this server which I'm getting
for work, the key issue is its ability to have a lot of hot swappable
disks. what I'm seeing these days is a migration to the 2.5" drives away
from the 3.5". The problem is the 2.5" drives only go up to 1 terabyte,

HGST has 1.5 TB 2.5" drives, but only at 5400 RPM.

while the 3.5" drives go up to 6 terabytes. so what's up with this 2.5"
drive bit. The literature says that they consume less power (the 2.5"

People doing a lot of random access prefer more but smaller disks.

drives) and are the favorite for data centers. But there's a factor of 3
difference between the storage capacity and size. so the problem is that
I have very few options when it comes to buying a rack mounted server
with 3.5" hot swap-able drives. there seems to be a lot more rack
servers with 2.5" drive bays.


Supermicro still has lots of servers with 3.5" disk slots. HP has some but they seem to require a special order with the suffix "LFF" (Large form factor). I don't see them on the website, but if you call and ask they are available. I don't know about 16 drives, though.

Can anyone recommend a system with 16 3.5" drive bays?

Actual media that you can take physically offline may still have merit.

I've heard tons of horror stories where some company's data, including all 
backups, were destroyed instantly.  Not just redundancy, but backups too.

I know of ONE company, where the only reason the company survived was because 
the CEO had a copy of the core IP on his iPod.

Offsite and Offline.  No substitute.
