4 2tb Hdd or 2 4 tb Hdd for storage Raid

[Sarahlou]

Hi I am looking to invest in a raid solution, but I dont know which one is better a 4 x 2tb raid 10 or 2 x 4tb raid 1 please? Obviously 4 tb is going to cost a little more but not by much. Any advice is appreciated

I guess, firstly, what are your reasons for wanting to use a RAID setup?

look out for cheap 2TB sky boxes and use 4 drives from those

I'm guessing it's so that you don't lose anything given any failure??

RAID 10 has slightly better performance than RAID 1, but is less recoverable if the controller fails, rather than a disk.

RAID 1 is probably your best option, if any disk fails then just replace it, if the controller fails then both disks can be used standalone to recover data!

Best for what ?

Performance, available space, future expansion, cost ? What are you priorities and why are you looking at RAID ?
