LSI MegaRAID SAS/SATA 9265-8i – WEI and AIDA64

WIN7 EXPERIENCE INDEX

The Win7 Experience Index (WEI) represents Microsofts 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 2654 MB/s  and provides our result as 7.9 in all categories.

AIDA64 DISK BENCHMARK

As a matter of course, we will run the AIDA Latency measurement to test the latency of the device. As well,  a great characteristic of hardware RAID cards is that they dont drain the much needed CPU resources of your computer. It just doesnt get better than zero usage!  In contrast a motherboard RAID would cost you CPU power, but the RAID card does all the calculations itself.

The LSI 9265-8i gets extremely good latency, due in part to being on the x8 PCI-e bus.   In general RAID cards will receive better latency than drives on onboard motherboard raid, and this holds true here, especially with the FastPath enabled:

And here is the read suite from AIDA 64:

LINKED INDEX

INTRODUCTION ~ EXTERNAL CHARACTERISTICS ~ BENCHMARK PREP

ATTO/CRYSTAL ~ AS SSD ~ HDTUNE PRO ~ WEI/AIDA ~ IOMETER

PASSMARK ~ VANTAGE ~ CONCLUSIONS AND THOUGHTS

If you want more detailed information on the testing, parameters and configurations used in testing, feel free to hit the forums! I will be happy to answer any questions, and as long as I have the hardware, if there is anything I have missed, I would be happy to run some tests for you and there will also be some more detailed presentations on 4k scaling for you enthusiasts out there 🙂 ~ Paul
