I'm planning to build a unraid server with the following components:

 

Case: Nexus prominent 9(comes with 2 4in3 HDD-trays)

Mobo: asrock 880gm-le

RAM: kingston valueram 2x2 GB DDR3

Power supply: Corsair CX500 V2

Cpu: AMD Athlon II X2 250

USB-stick: Sandisk cruzer 16GB

HDD: 4x WD Red NAS drives WD30EFRX

        or WD Green WD30EZRX

 

My quistiones are:

Are the WD Red drives worth there price against the green drives?

Witch cables do i need to buy extra? (HDD 4x3GB new, 1XWD2TB and 1xWD1TB)

Is that 1TB HDD (WD10EADS) suitable for a cache disk?

Which blu-ray drive should i buy to rip my collection of blu-rays?

 

Thanks in advance,

David

 

 

 

Are the WD Red drives worth there price against the green drives?

The WD Red drives are a brand new animal on the scene. On paper they should outperform the Green drives and only have marginally higher heat and power consumption. However, they are unproven, and that makes them slightly risky. I certainly would preclear at least 3 cycles on one before I used it.

 

Is that 1TB HDD (WD10EADS) suitable for a cache disk?

That all depends on how much data you intend to move into the array. I'm currently using a 250GB 7200 rpm Seagate that I got out of an HP N40L Microserver. At 1 TB and below, the prices are so close together it's almost silly to buy something small, but even 250 GB is plenty for my uses.

 

Which blu-ray drive should i buy to rip my collection of blu-rays?

I just got one of these Pioneers, and it's very fast for ripping.

 

Oh, and welcome to unRaid.

Thanks Aiden,

 

I'll go for the greens for now and buy some reds when they are cheaper and have proven themselves.

 

I was planning to start with 8TB And work my way up from there, but if 1TB is to big for cache, I'll start with 9TB and look around for a small HDD for cache.

 

So any recent A-brand Blu-ray drive is good enough, I was planning to buy the ASUS BC 12B1ST

...but if 1TB is to big for cache...

 

I don't think it's too big. I was just saying you don't have to worry too much about capacity for the cache drive, unless you plan on moving large amounts of data.

I think his point was don't spend more money than you have to. If you have an old drive laying around, one in an enclosure you don't use, a friend that will trade you one for something, something like that. Save the money to use elsewhere because after you move all your existing data to the array the cache drive really doesn't need to be that big. I use a 320GB laptop hard drive I had lying around, for instance, but I could easily get away with something smaller than that

I used the 1TB disk for back ups, so that isn't a problem. So i will use the 1TB disk as a cache disk and replace it when i find a smaller one.

 

 

 

 

 

the biggest concern for a cache drive is that it is stable.

 

you dont want to use a drive that has been bouncing around your little brothers desk drawer for several years...

the cache drive is a single point of failure in unraid. try to use one in good shape.

 

as far as. the size. there are 2 thoughts.

1. either as big as or larger then your average days transfers.

2. the same size as your parity drive so that you have a spare drive in case any fail.
