LSI 9265-8i MegaRAID Card vs Adaptec 6805 RAID Card – The Ultimate 6Gb/s RAID Showdown

OWC MERCURY PRO – PASSMARK PERFORMANCE TEST 64 BIT

We will be using PassMark to determine the performance of the respective cards utilizing SSDs in a server scenario.

PassMark testing uses mixed read/write patterns to measure performance in high impact server applications. Mixed Read/Write ratios are the hardest type of loading for any storage device, and under constant loadings in server environments, the solutions will be reading and writing simultaneously at high levels of load. The read write ratios are as follows;

  • File Server 80% Read / 20% Write
  • Web Server 100% Read
  • Workstation 70% Read / 30% Write
  • Database 90% Read / 10% Write

The 9265-8i here pulls ahead easily, outpacing the 6805 by large margins.

OWC MERCURY PRO – ANVILS STORAGE UTILITIES

Anvil’s Bench is geared towards providing important metrics for SSDs in general, and particularly RAID arrays. The plethora of information at different Queue Depths, and the ability to adjust the compressibility of data is very important when testing different solutions. There are varying levels of Write testing involved, which can be very useful for the sake of comparison.

I unfortunately have the Adaptec 6805 controller and… LOL… where is my garbage can…
I’m running a setup with 4x Kingston 240GB HyperX in R5, the ATTO results arent that shabby… I get 1.5GB/s write and 2.1GB/s read (seq) but…. the short random reads are just terrible… in Winsat it’s only 170 MB/s(!?!).
Funny thing is that when I turn off controller cache I get 9000 MB/s in sequential 64 read… 🙂
I dont however get more than 5ms max response time vs your 55ms value.
