Answer: A
Explanation:
ReadyBoost
Windows 7 supports Windows ReadyBoost. This feature uses external USB flash drives as a hard disk cache to improve disk read performance. Supported external storage types include USB thumb drives, SD cards, and CF cards. Since ReadyBoost will not provide a performance gain when the primary disk is an SSD, Windows 7 disables ReadyBoost when reading from an SSD drive. External storage must meet the following requirements:
– Capacity of at least 256 MB, with at least 64 kilobytes (KB) of free space.The 4-GB limit of Windows Vista has been removed.
– At least a 2.5 MB/sec throughput for 4-KB random reads
– At least a 1.75 MB/sec throughput for 1-MB random writes
