hey just a question
if i get a 4 bay NAS can i create mix volume eg like 100GB mirror volume while the rest is RAID5 volume ?
lets say i put in 4 x 1TB disk.. i have 4TB raw... i cut out a 100GB mirror so that leaves me with 3.8TB and if i raid 5 that i'll loose 1/3 parity for redundancy which is 1.26TB, so i'm left with 2.54TB volume ?
sorry, in QNAP or Synology, you only can select which HDD and what type of RAID u like to create.
for exp:
4 x1TB HDD, you can create:
1) RAID-5 with 4 x 1TB , u get volume size ~3TB
or
2) 2 x RAID-1 with 4 x 1TB, u can get 2 volume each with 1TB volume size.
if you take the HDD and install into PC, you will SAW 3 partition : System /swap / data.
