You see, Vista ‘forgets’ the key after resuming from sleep which invalidates all the ReadyBoost data already held in the memory device forcing it to flush and start over. The cause is a simple yet stupid oversight in the design of ReadyBoost’s security system which encrypts all cache-data with an AES-128 encryption key, a great idea badly implemented. The problem causes irregular and unnecessary hard-disk thrashing after resume which can take up to 8 minutes to settle down – ironically the outcome is the exact opposite of ReadyBoost‘s purpose to increase responsiveness by caching.
