OCZ Vertex Series 120GB SSD Performance Preview – Indilinx makes an intro

HDTach 3.0.4.0

HDTach v3.0.4.0 

---

HD Tach will test the sequential read, random access and interface burst speeds of your attached storage device (hard drive, flash drive, removable drive, etc). All drive technologies such as SCSI, IDE/ATA, 1394, USB, SATA and RAID are supported. Test results from HD Tach can be used to confirm manufacturer specs, analyze your system for proper performance, and compare your performance with others. HD Tach is very easy to use, quick, and presents data in easy to read graphs, including the ability to compare two storage devices on screen at the same time for easy analysis.

The burst rate seen by our HDTach benchmark is somewhat confusing as it is considerably lower than the other scores from SSDs we have tested.  Even more interesting: the burst speed is exceed by both the sustained read and write speeds.  The issue is likely in how the cache on the drive is utilized; either way it’s the 223 MB/s read and 199 MB/s write speeds that really impress us.
