Hi,

I want to build a NAS using 6x3TB combined with RAID-Z and AES-encrypted.
I read about a lot of performance issues when using aes, especially when using the built-in aes encryption under solaris.
I need to have at least 80Mbit in both directions, is that a reallistic goal when using some cheap intel i5 processor with AES-NI and 16GB of RAM?
 
no idea about zfs aes performance, but if compared intels aes-ni vs normal amd, performance is like encryption wouldn't be turned on
 
ok thanks, I knew that it is like this on paper (when I benchmark truecrypt with my i7 i get like 3gbit) but I was not sure that this holds in practice.
 
Speed tests based on my laptop: i7-3720QM

without aes-ni I get for aes256 103MB/sec
with aes-ni I get for aes256 503MB/sec

Using aes on my internal ssd, I see hibernation speeds of 350MB/sec, the ssd itself can do about 400MB/sec.
