Building your own NAS, really!

88MB/s write is rather poor for a RAID 5 system. He should've used a better RAID controller, or at least a stronger CPU, like one of the AMD CPU's and not the silly Intel Atom.

I do give him credits for the looks of that case, as well as the way the drives are arranged!
I'm also fairly sure that I saw the same design a few years ago, but then the total storage space was much less ofc.
 
Pada dis selfde NAS as wat jy gesien het, behalwe dat die link wat ons gevolg het na die ou se eie website toe gegaan het (as jy soek vir Black Dwarf NAS dan sal jy dit kry).

Sy eie website het bietjie meer inligting op.
 
Wonder how many hours before the drives start failing, running at a +/- 20 degree angle?

Drive angle is not relevant measure for predicting drive failure.

My NAS running with 6x2TB Seagate is still running strong 1 year later. 1 drive failure thus far.

88mb/s is actually not bad. Getting 67mb/s here (avg), bursts up to 80mb/s.
 
I gave up with my home built NAS device. The throughput was pathetic from PC to NAS.
 
Kuga: what hardware did you use for your NAS, and what speed + brand network cards were you (both in your PC & NAS) using?

I'm still curious to see how my speed will improve if I change my partition type from NTFS to Ext4, since I'm currently using Ubuntu where its NTFS-3G driver is rather CPU intensive.
 
It would probably still be cheaper to get a HP N36L MicroServer. Maybe add a dedicated RAID card to it. Maybe even add an additional NIC.

I managed to get an average of between 65 and 90 MB/s depending on the file size.

EDIT: Above speeds recorded with a single 2TB Samsung EcoGreen SATAII HDD. No RAID.

I used the PC in my sig, and I had a E8400 with a Gigabyte EP45T-DS3R. I bought an Intel Pro 1000 NIC for the NAS and used the Intel onboard LAN in my main rig. Had a Cat5e crossover cable.

Installed FreeNAS on a flashdrive and booted from there.

My overall speeds was about 30 mbps.

30MB/s isn't that bad?! 30Mbps is terrible, unless you're using WiFi like I am :)

I'm also running the HP Microserver with 4x2Tb Drives in Software RAID5 under Ubuntu Server. I am also seeing ~60 - 100MB/s depending on what I am copying.
What I did find is that it depends on the quality of your network cards as well.... I use to only buy the "cheap" network cards, but with them I am seeing max 35Mb/s....

what network card are you using?

I am using the onboard Network card in the MicroServer, as well as the onboard card on my PC's motherboard (I think it is a Intel based card...)
I have another 'server' which has one of the cheap Realtek cards, and traffic to that machine is slow (~30MB/s)
 
You need to enable Jumbo packets on that Proliant running Linux or the output is slow on a gigabit network... [

My ZFS flies - 4x 2TB Samsung's running in Raidz1. Running on an HP Proliant Microserver.

See below. I can run further tests / comment on config if you like? OS: Debian Squeeze , ZFS install = zfs-fuse , apt-get install zfs-fuse (as easy as that )
