The Parkdale is a hard disk performance test utility. With the Parkdale you can measure the read/write speed of a hard disk, CD/DVD disk, USB flash drive or network drive. Parkdale has three test modes: QuicklAccess, FileAccess and BlockAccess. These can be used to test hard drive performance in a variety of conditions. You can choose to test multiple drives at once. Parkdale will test them one at a time and record the results in log files. So you can compare the performance of different drives.
