Yup. 4 drives standard. And with additional controllers you may go up to 14 SATA drives in total. But honestly, for $20 I would get something with 6 SATA ports to start with.

6 sata ports...
4 not enough?
still looking for SUPER LOW COST 4TB Smile

because money wize,
i think i'd have to go with these

[CPU] AMD Sempron 2.7GHz AM3 45W Single-Core ($37 + $0)
[RAM] Kingston 1GB 240-Pin DDR3 1066Mhz ($13 + $10)
[MOBO] Foxconn M61PMP-K AM3 NVIDIA MicroATX ($47 + $0)


if its ok... of course....

and i want to know those cards that expand the SATA ports like u said,
can you show me one?
and what port it needs?

PCI
PCI Express x1
PCI Express x2
PCI Express x8
PCI Express x16
PCI Express 2.0 x16

That is what you are looking for today, but in three years 2TB will be a pen drive. Heck even today I fill 4TB in about three months on average. You don't want to have to re-buy everything so soon. A little more money now gives you four extra sata parts in the long run (2 sata plus an extra PCIe 1x slot that can be two sata). Most decent and cheaper NAS tower cases hold 10-12 drives. You will waste space and money with such a limited mobo.

Speaking of which, there is basically two good cheap NAS cases. Which one do you like more:

Supermicro AOC-SASLP-MV8

This is a 8 port SATA controller on a PCI-E 4x interface that will fit into the PCI-E 16x slot on that MB.

thanks maxinc!

your right about the mobo Poof,
know you were, you convinced me,,,
might as well pay the extra $13 and have built-in 2 xtra SATA ports...
rather then paying $30 later on for a SATA CONTROLLER card that has 2 SATA ports....
so im with these so far
[CPU] AMD Sempron 2.7GHz AM3 45W Single-Core ($37 + $0)
[RAM] Kingston 1GB 240-Pin DDR3 1066Mhz ($13 + $10)
[MOBO] BIOSTAR A770E3 AM3 ATX ($60 + $0)
[PSU] CORSAIR CX430 430W ATX12V Active PFC ($45 + $4 - $20 MIR)

now the second case link i cant view,,, :/

Is this 100% true? There are some good PCI SATA controllers available... such as the Promise TX4. I would look to see what is compatible with your NAS system as well... some OSes can be picky about hardware.

At any rate. I think the Promise TX4s are nice and can offer a good 4-port SATA controller on PCI. Using it for ZFS seems to be successful for many people. Plus, you can grab them cheap on eBay.

I understand that basically makes the PCI your bottleneck... but at 113MB/s (or whatever you stated was the theoretical max) you should be fine. GigE maxes out around the same speed. So if you would get a super-fast PCI controller then your speed will be limited by network anyhow (unless we are talking internal transfer speed and access, which is usually not a big deal in a dedicated NAS).

Any other thoughts?!

I have an AMD single-core in my NAS. Works great! Passive cooling in an Antec 300.

so i can understand better,
when looking for a NAS CASE, i need?

External 5.25" Drive Bays 9

External 3.5" Drive Bays 1 (Exposed; converted from one 5.25 inch drive bay)

Internal 3.5" Drive Bays 4 (Hidden; from one 4-in-3 Device Module included)

Expansion Slots 7

PCI controller is fine as long as there is only one drive reading or writing on the PCI bus. During parity check for example, when all 4 drives are reading data simultaneously, their combined bandwidth can not exceed 133MB/s which results in an effective theoretical read speed of 133 / 4 = 33.4MB/s which is more like 22-24MB/s in real life. Combine that with a 2TB drive and you may have to wait a long time for a routine parity check. It gets even worse if you have 2 of these installed on the system.

Seeing the rate at which my storage requirements grow, I tend to look at cases with lots of 5.25" slots available since I can use 4 in 3 cages to fit 4 drives into 3 x 5.25" bays. This strategy if more future proof but it requires spending some extra cash on something like this:

For the scope of your project, I think the Antec 300 is the better choice for keeping costs low, while the CM seems a bit more expandable.

I would expect some cooling challenges with this particular case.

Good point. I am curious though... is it possible that the SATA controller has onboard circuitry to help with performance. Since they have to know that PCI would be a bottleneck.

ok lets hold on for sec,,, my Head is spinning,,, Tongue

#1.
is it that bad to use a PC Case that includes its own PSU?
it could help with keeping things Low Cost...
but since a Server Runs 24/7, i guess,
what exactly why i need a very good PSU right?


#2.
since my Mobo has 6 sata ports by default,
i should select a 6x3.5" internal drive bay Case?
or
a case with at least 2x3.5" internal drive bay + 3x5.25" External Drive Bay + 4-in-3 Module Cage?

thx
