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.

DDRdrive hits the ground running - PCI-E RAM-based SSD - Storage  1

For uncached SSD based storage, burst speeds will usually end up close to the maximum read speed.

DDRdrive hits the ground running - PCI-E RAM-based SSD - Storage  2

The ioDrive wins the raw throughput race with 4 lanes of PCI-Express available.

DDRdrive hits the ground running - PCI-E RAM-based SSD - Storage  3

SATA based SSD’s usually run at 0.1ms, while PCI-E based SSD’s usually run at 0.0ms.

It may seem like the DDRdrive is losing the race here, but remember, raw throughput is not what this drive is made for.  It is designed to be hammered with small random reads and writes.  Indefinitely.  For this we had to engineer a few focused torture tests…
