OCZ Vertex 120GB SSD Review

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. What else can you say when you look at a random access this low! As we said in the Falcon review; 0.10 versus 0.09 is so close as to be considered a tie and that really is saying something. To us the Indilinx-based SSD’s and the Intel X-25M are the drives to beat and have set the bar so high it’s in the metaphorical equivalent of the “nosebleed” section of the ballpark.

SIS Sandra

This test was run with the removable storage benchmark in Sandra XII Standard. All of the scores are calculated in operations per second and have been averaged out from the scores of 4 test runs.


As we said before, both the Vertex and Falcon are of the same breed and thus their performance is virtually identical. That being said, the Vertex shows itself to be one hell of a drive once again.
