World Exclusive: OCZ Agility 4 128GB SSD Review

AS SSD Scoring and File Transfer Test
AS SSD determines the performance of Solid State Drives (SSD). The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD. These tests are carried out without the use of the operating system caches. AS SSD is also a great way to find out what model of drive you have, if the drive is properly aligned, and what firmware is on your drive (firmware will be not be listed in RAID 0).
The highly incompressible data used by AS SSD magnifies the performance drop off when reading sequential incompressible data. Other than in that particular category the Agility 4 puts up very impressive numbers easily surpassing all MLC 120GB SandForce drives.
The Agility 4 is taking a hit here because of the sequential incompressible nature of this test. The Agility does still manage some pretty good numbers. Typically the copy test is very consistent when measuring the transfer rate of async. drives. By that I mean there is really not a big difference between the transfer rates of the ISO, Program or Game copy tests. The 3 async. drives on our chart, the Corsair Force 3, ADATA SP900 and the OCZ Agility 4 demonstrate this.
