Areca 1880ix-12 PCIe 6G SAS RAID Controller Review SSD IN RAID 0 – WEI & HDTune Pro


The Win7 Experience Index (WEI) represents Microsoft’s method of rating computer systems and, more specific to our usage, provides a storage evaluation through a graduated rating system up to 7.9 on pc components and the system as a whole.

This benchmark is built into Windows and anyone can use it by simply typing:

  • Go to Win Orb/All programs/Accessories and right click on the Command prompt;
  • Click Run as Administrator
  • In DOS, type winsat disk and hit enter.

WinSat itself measures our transfer speeds at almost 3GB/s  provides our result as 7.9 out of 8 in all categories.

Hey Microsoft!  Whats it take to get that 8?!?!?


HDTune shows some interesting parameters that others do not and the most interesting which pertains to this review in particular is the Cache Test. This test is integral in our evaluations as our primary purpose is to effectively display the power, speed, and flexibility of a controller with a large amount of cache.

The random seek times of 8kb are roughly 2.5 GB/s which we believe few will ever see again except for in a review such as this.  The card is being pushed to its limit and these measurements are of random transfer and NOT the high sequentials we are so use to seeing advertised in storage products.  The card is also demonstrating excellent latency numbers.

    Microsoft’s WEI score only goes up to 7.9 in Windows 7, not 8, so nothing can get higher until they update their scoring scheme.

  2. Yes, it is a joke of sorts 🙂
