WD Scorpio Black 320GB SATA Hard Drive ReviewTue, Apr 21, 2009 - 12:00 AM
Everest Disk Benchmark
Legit Reviews has just started benchmarking physical drives with Everest Disk Benchmark before, so we will only be looking at the performance of the Scorpio Black 320GB hard drive. This benchmark is designed to measure the performance of storage devices including SCSI and ATA hard disk drives, RAID arrays, optical disk drives, Zip disk drives, flash memories, etc. All of the used benchmarking methods used in Everest are synthetic tests, and so they may not reflect the real-world performance of the tested storage devices. None of the used benchmarking methods include any manufacturer specific optimizations, and they never change the operating conditions upon the detection of a specific storage device model. EVEREST Disk Benchmark Version 2.06.37 was used for testing.
Benchmark Results: The linear read benchmark shows that the drive starts out with 85.2MB/s drive speeds at the start of the test and slows to 43.7MB/s at the end of the platter. When it came to the Random Read test the drive scored 53.1MBps and then with a buffered read it reached an average of 219.7MBps. The average random access was again shown to be 13.60ms, which is close to what HD Tune and HD Tach showed in the previous benchmarks.
Benchmark Results: This test is designed to measure the performance of the storage device interface (when it’s possible) by writing only the very beginning of the surface repeatedly. This test will work only with storage devices equipped with built-in cache memory of at least 64 KB. The average write speed for this benchmark using 128KB block sizes was 196.0MBps.
Benchmark Results: The random write test is designed to measure the random writing performance of the drive by writing 64KB data blocks to random locations on the surface of the device. The WD Scorpio Black averaged 67.7MB/s for this task.
Benchmark Results: The final write test that was run was the random access test, which is designed to measure the data access performance of the drive by writing small data blocks to random locations on the surface of the device. The WD Scorpio Black 320GB hard drive had consistent access times across the drive and averaged 7.5ms, which great for a notebook hard drive.
