Drive needs

[karl0508]

Hi guys looking to build an ITX nas

 

I have about £40 for a case so looking at the SG13B or the Evolv ITX or Elite 110/130

 

The question i ave to ask is how do i work out my drive needs? Currently i fill about 750gb and don't see me getting much more, But now i'm building a nas i have the 3 case choices 

 

the SG13B is my favorite but would make me have 3 1tb wd red in raid 5 with a ghetto SSD mount for Ubuntu, or the evolv would allow 2 3.5" drives, and the elite would be 3 3.5" drives, which would be my best choice? i love the SG13B but would i be better with the elite? the evolv its huge

 

But what would be the best drive configuration for my home nas/server it's only for media and all my important docs will be on it and also be on the cloud

 

HELP

Hey karl508,

 

It is recommended to have some level of redundancy when you are building a NAS. Having a device running 24/7 puts a good amount of usage on its parts and you'd want your data to be safe. I would suggest going for the case that allows you to create a RAID array that provides redundancy (RAID1, 5, 6, 10, etc.). 

Also I would suggest using NAS/RAID class drives for such a build as they have additional features that enable them to work much safer and optimal in these environments. You can check out WD Red, for example: http://products.wdc.com/support/kb.ashx?id=QCZtZV

The SG13 will allow me to raid with 3 2.5" drives giving me 2tb in raid 5

 

but would i be better going for the evolv and having more storage options as in 3.5" drives?

 

Is there a way to work out how much storage you should get?

More 3.5" bays mean having the opportunity to have more drives in your system and thus a larger choice between RAID types. 

It depends on how much storage you need to have. Each RAID type uses a different amount of drives for the redundancy. RAID1 mirrors a drive onto another one, leaving you with 50% of the total capacity. RAID5 uses the capacity of one of the drives for the redundancy, leaving you with the total size minus one of the drives. RAID6 uses two drives. RAID10 uses half of the drives in the array (no matter how many they are). For a 3-drive array with three 1TB drives, you would have about 2TB of usable space.

looking at the evolv which will take 4 3.5 drives but the sg13b only takes 3 2.5 drives

 

WD need to make WD RED 2TB 2.5"

Sadly 2TB 2.5" WD Red drives are not available at the moment. The only drive that is 2TB from the 2.5" line from WD is WD Green, but I would use them in RAID with caution since they are not designed for that purpose. Maybe there is an option for an expansion card on the PCIe slots? If not, you could look into other cases.

if i go for the evolv itx i can have 4 3.5" drives so wouldn't be an issue 

 

but 2tb red 2.5 would be heaven
