I have a DNS-323 NAS on my home network that I use only for serving files. I have two 1 TB disks in a RAID 1 array. The specs for the DNS-323 are:
CPU = 500 Mhz Marvell 88F5181 proprietary Feroceon ARM CPU
RAM = 64MB
IDE controller = Marvell 88X7042
LAN = Marvell 88E1111
I have been thinking that a fun project would be to setup a Raspberry Pi as a NAS on my network. From reading the boards, it seems like this can be done fairly easily with a USB external disk and Samba. I guess my question is does anyone know how the performance might be in comparison with the DNS-323. The specs of the Pi are better but I am wondering if the USB connection to the disk might be a bottle next. I really do not know much about how all of this stuff works.
