[CentOS] OT: Replacing Venerable NAS

I have an original-label Infrant (now NetGear) ReadyNAS storage 
appliance that's been running for 8+ years. Except for replacing its 
power supply, it has not skipped a beat in all this time.

I use it primarily as a backup device (via NFS) for a couple of Linux 
machines, (via SMB) for a couple of Windows PC's, and (via ftp) for web 
sites at my hosting provider.

SMART+ reporting shows ~75K hours operation, with zero sectors 
reallocated, on each of the four disks.

I'm thinking I should be looking for a replacement, even with all this 
good info/luck.

Would like to hear recommendations here.  Besides the ReadyNAS, I have 
worked with a Thecus NAS (don't recall model). What are the features I 
should look at?

Thanks.
