3.5 Terabyte NAS Reviewed

Steve Kerrison writes "Thecus' new N5200 NAS can hold five SATA drives, which with currently available drives means up to 3.5TB (or 2.75TB in RAID-5) of storage before formatting. From the review: '£600. That's roughly what this will set you back, minus hard drives. Add in five 750GB drives and you'll be forking out a number closer to two thousand. However, act a bit more modestly and you can still have a terabyte (even in RAID-5) for under a grand.'"

one GBP is worth more than one unit of other currencies

There are some exceptions; probably amongst others, the currencies of Bahrain, Kuwait, Cyprus, Malta and Oman are all worth more in units than GBP.

Yeah the N5200 does use linux. But I did not find any clear hint to this on the Thecus website.

Also I'm missing any documentation of how to upgrade the firmware to your own linux system.

If you want the source of their linux look here:
ftp://ftp.gpl-devices.org/pub/vendors/Thecus/

They tried to hide the linux, but without success:
http://gnumonks.org/~laforge/weblog/2006/02/24/

So until they openly say they are using linux and offer a way to upgrade the software on the system I will NOT buy one of these.

I did think about getting one of these. It has really nice features and if I could put my own linux system on one of the hard disk I could use it also as a dsl router and proxy (squid).

Anyone knows of a similar device with an upgradeble linux?

I built a 2Tb storage device w/another 250Gb for the OS a couple years ago as a backup solution for ~30 colo servers. I used a Tyan dual Xeon motherboard (there is a lot of compressing taking place on this machine), A 3Ware hardware RAID card, and a Chenbro 3u rackmount case with 12 SATA hot-swap bays and a single internal bay. I put 13 250Gb drives in it (2x250Gb software mirrored for OS, 10xRAID5 = 2Tb storage and 1 hot spare).

At the time the cost was ~$4000 while commercial solutions were closer to ~$8,000. I used CentOS 3 as the OS (4 was still in beta) and had to use the centosplus unsupported kernel in order to use reiser on the 2Tb array -- ext3 didn't work for some reason that I don't recall. The 3Ware card showed up with stock kernel modules as a SCSI controller.

I assume someone could build a similar system for about the same cost with much more disk space now. Also, if cost is a factor, the hardware RAID card (~$800) could be dropped in favor of software RAID and a single processor mobo could be used. I really** like the Chenbro case though and for the extra cost it leaves a lot of room for expansion if you were to start with only 5 drives and wanted to expand later.
