XtS-AES (XEX-based Tweaked CodeBook mode with CipherText Stealing for AES) is suitable for parallel operation because it includes both a nonce and a counter, allowing for the encryption or decryption of multiple blocks simultaneously. Unlike CTR mode, which also supports parallelism but doesn't inherently include a nonce in its basic description (though in practice, a nonce is often used with CTR), XtS-AES is specifically designed to enhance security for disk encryption, making it well-suited for operations that can benefit from parallel processing.
