I need some help understanding why my Patriot warp SSD hard drives are operating so slowly
I recently started building a new computer after a bit of benchmarking research I decided to use two SSD’s and put them in a raid 0 configuration. Everyone I talked to told me that this would be the fastest solution for under a grand.
I placed the drives in raid 0 with the built in motherboard raid controller installed windows and everything runs fine but I couldn’t help but notice that it wasn’t booting/ running nearly as fast as I predicted. So I decided to benchmark it and compare to my old hard drive running the same setup. My RAID-0 Patriots 60 Mbps read and my old western digital got 70 Mbps. This shocked me to see even though running the SSD’s didn’t seem fast. I thought that they would at least benchmark as fast as a old school HHD. Just using 1 of these drives by themselves seemed to run much much faster than the two together (I didn’t benchmark this setup because it was before I knew of the problem)
So I am confused, I was expecting at least 200Mbps (A hopeful estimate) in my research I found that the drives I’m using benchmarked alone at 120Mbps
Go download HDTune Pro, and submit the benchmarks of:
- normal benchmark
- File benchmark (set file size to 64MB)
- random access benchmark
That should give us a fair idea of your striped SSD's performance.
The Patriot Warp series uses the JMicron JMF-602 controller which has been blamed over the web for slow operation with small random writes - the random access test should show this. So it is part of the family of slower SSDs; not part of the higher-performance SSDs with controllers like Intel, SandForce or Micron.
4000 IOps, 240MB/s sequential read and 140MB/s sequential write. The IOps are on the low side, but its normal for JMicron; actually pretty good scores i'd say. But two bad SSD don't make one good SSD; an Intel SSD will still be many times faster.
However, i don't see any obvious performance issue here.
