Re: No thanks
I've got a Thecus N7700+ from a few years ago.
Runs some kind of linux 2.6 from flash, has a nice lot of modules, supports iscsi, and i've seen reports of people upgrading the CPU from a celery to a dual core something or other and increasing the RAM from 2 to 3 gb.
I might do this at some point to increase the performance.
I've got 7 x 2gb WD "Green Power" drives in it, running RAID5 and encryption, and it's great.
Max read rates are ~50mb/sec for me, which isn't bad I think from an encrypted ZFS drive and software raid (there's 2 marvell RAID cards in there running md).
The interface isn't great - it uses flash (yuk), and the "English" can be a bit confusing, esp. if you're hesitating about swapping a failed drive, but from a HW point of view, I love it.
Encryption's great as you just boot it with a usb stick with the key stored on it, and then remove it once booted.
I've had 2 drive failures, and swapping them has been dead easy, although at 2tb each, rebuilds take around a day.
I'm seriously thinking of getting another one, and you can connect 15 of them together with iSCSI, which is nice.
They are doing rack mount beasties now up to 16 drives, which is good too, the only problem is their newer offerings don't support ZFS as far as I can tell, which is a real shame, and they are starting to include HDMI and audio ports, which is a bit pointless for a NAS, IMO.
I guess they are just using standard motherboards so don't have much choice.
