Sisoft Sandra – File System

Another common benchmarking program, we have SiSoft Sandra File System Benchmark. The File System Benchmark gives us a quick glance at the overall performance and whether we have a new or full drive, the performance is both consistent and comparable to the 64GB Indilinx drives and 128GB second generation Samsung based drives.

Corsair stays with the class in our File System benchmark. This time we see little difference between a 128GB drive and a 64GB Samsung controlled drive. The one slip I kept seeing was the slow random write speed when the drive is full. The P64 is only performing at 25% the original rate as the newly installed drive.

SiSoft Sandra – Physical Disk

The Physical Disk Benchmark benchmarks the hard disks and not the file system, meaning the graph below compares the performance of the physical disk to the storage adapter, unlike the SiSoft Sandra File System benchmarks which shows performance between the file system itself and the adapter.

The Corsair P64 takes the cake in the Physical Disk benchmark. The random access time is the quickest we’ve seen in a while and the index speed is right at the top with only a 7% difference between a new and full drive.

HD Tune

HD Tune is another hard disk utility to determine the performance of your drive. HD Tune runs a few tests to provide a transfer rate (minimum, maximum and average). It also trends the performance through the entire disk and gives you the access time, burst rate and CPU usage.

New Drive

Full Drive

HD Tune lets us clearly see the performance drop between a new empty drive and one that is completely full. The empty P64 gets to spend about half its time up in the 200MB/s barrier where the full drive stays relatively flat at 170MB/s. The burst speed, random access time and CPU usage is not affected by the free space of the drive, this is a very welcome change compared to the Indilinx drives I’ve worked with in the past; it’s often a 20 point increase in percentage when the drive is full.

HD Tach

HD Tach is a low level hardware benchmark for random access read and writes. The performance numbers are quite similar to HD Tune.

New Drive

Full Drive

Basically the same HD Tune story but imposed onto the HD Tach graph. There is roughly a 20MB/s drop between the new and full drive.
