Corsair P64 64GB SSD Review

Crystal DiskMark

Crystal DiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows to measure sequential and random read/write speeds; and allows you to set the number of tests iterations to run. We left the number of tests at 5. When all 5 tests for a given section were run Crystal DiskMark then averages out all 5 numbers to give a result for that section.

Read

When it comes to read speeds in Crystal DiskMark it appears the Samsung controller is the equal of the X-25M first gen in the all important small file 4k read test. It also posts some impressive numbers in the larger tests, but the small read test crown still resides firmly in the Indilinx camp. Score another one for the EX-Samsung employees.

Write

As with the read tests, the P64 posts some very good 512 and sequential write numbers but falls flat in the crucial 4k write test. We suspect that with some fine tuning of the firmware this issue could be alleviated, somewhat, but we doubt if this controller will ever match the Barefoot, let alone the power house called Intel X-25M…128MB of cache or no.

Random Access Time

To obtain the absolute, most accurate Random access time, h2benchw was used for this benchmark. This benchmark tests how quickly different areas of the drive’s memory can be accessed. A low number means that the drive space can be accessed quickly while a high number means that more time is taken trying to access different parts of the drive. To run this program, one must use a DOS prompt and tell it what sections of the test to run. While one could use “h2benchw 1 -english -s -tt "harddisk test" -w test” for example and just run the seek tests, we took the more complete approach and ran the full gamout of tests and then extracted the necessary information from the text file. This is the command line argument we used “h2benchw 1 -a -! -tt "harddisk drivetest" -w drivetest”. This tells the program to write all results in english, save them in drivetest txt file, do write and read tests and do it all on drive 1 (or the second drive found, with 0 being the OS drive).


WOW. Score one for Samsung! The lower the latency the snappier your drive will seem and boy this thing is FAST. 0.08ms is best in class performance and is simply amazing.
