Hello Thought I'd ask before I do something stupid I'd like to encrypt my fileservers with Bitlocker but I wonder how fast it is these days? The servers run Windows 8.1 and when trying on another system I get about 100MB reads and writes during encryption - is this somewhere in the ballpark for performance? Oh and the cpu supports hardware encryption as well Thanks in advance Edit: Just finished encrypting a Raid6 array with 8x2TB drives. Time approximately 24 hours and an average speed of about 125-130MB/sec. Cpu is an AMD A4 5300 dual core cpu. Not so bad imho.
