Asustor AS6404T 4-bay NAS Review

The hardware encryption engine in the AS6404T works pretty well in both RAID 5 and 6. In RAID 6 the drive drops just 12.7MB/s when writing an encrypted 16GB folder of data and just over 10MB/s when reading the data back. In RAID 5 mode there's a 12.9MB/s drop in write performance and 12.5MB/s fall in reads.
