OCZ Vertex 4 512GB SSD Initial Review - Vertex Returns to its Indilinx Roots (Firmware Progression Testing)

Subject: Storage
Manufacturer: OCZ Technology

HDTach 3.0.4.0

 

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.

Bursts are provided only for your review. SSD's don't cache the same way HDD's do, so burst testing typically results in figures that are lower than the sequential throughput figures. That said, they were particularly low for both Vertex 4 firmware revisions. More on that later.

HDTach feeds the tested drive a continuous string of small sequential read requests. This is a single threaded operation, which means the SSD doesn't get to see what's coming next. OCZ has told me the Vertex 4 firmwares (both of those tested) have low performance on sequential reads at low queue depths, and this is clearly shown here.

This test hints that the 1.30 firmware may have slightly lower latency as compared to 1.52. More on that once we get to IOMeter testing later on.

What I take away the most from this review is how impressive the Samsung 830 series really is. I cannot think of a better SSD to recommend than the Samsung drives.

Also, could you please include the Crucial M4 if possible in future reviews? It could at least represent the Marvell controller against the Sandforce and Indilinx, which would be great. I'll stop spamming the comments now!

2nd this request especially since these are down to just over a buck a gig for the 512's.
Thanks
