So ..many of you will know of my obsession with collecting 'data' ...
and that I love NAS ..
My latest addition was a ReadyNas 4 bay unit ...which were fitted with 4 x 4TB hard drives WD red ..
Configured in raid X ..which is netgears version of raid5 ..
So ..useable space is always less than the drives actual size ...and in raid as a rule of thumb ...one of the 4 drives provides the stripeing thus you lose the storage capacity of one ...
Thus we are looking at 3x 4tb ...less a few hundred gb.
The actual capacity being more like 11 tb ..
Enough for most folk I guess ...but not for me ...
I'm therefore going to upgrade again to 8tb drives ..but not all at once as these are about £300 each..
So to my questions.
I intend to replace each 4tb one drive at a time...
(less financial pain that way)
lol
I assume I can hot swap one drive first and allow the NAS to rebuild the missing drive...using only 4tb of the new 8tb drive ?
Once the rebuild is complete ...in theory I can repeat this until all 4 x 4tb drives are physically replaced at which point I assume I can reboot and the unit will re-sync giving access to more or less 8tb on each of 3 of the drives (one will of course be lost to stripeing as is the rule..)
Eventually I will have approx 22 > 23 tb of accessible space ?
Do I have the method and the concept correct ?
A question for NAS experts I guess ..
Hopefully one day 8tb wd red drives will fall ..but for the moment ...this excercise is going to cost as much as a central heating system...just for 4 drives ..
about £1200 when complete..
Ouch !!
