i need high speed disk encryption (many disks running in parallel, lots of data movement). i have processor with AES-NI. geli give 150MB/s performance (tested from/to md ramdisk) using default and recommended AES-XTS and ca 400MB/s read and 700MB/s write using AES-CBC. I'm not cryptography expert, is CBC somehow "less secure", and if so is it really a problem?
