Storage Spaces vs RAID - Am I missing something?

-

hi guys, 

i've been tasked comparing storage spaces on windows server 2016 vs hardware raid.

for test hardware is:

  • 2x 12-core 2.4ghz cpus
  • 512gb ram
  • 2x ssds
  • windows server 2016 (running no workload except benchmark tool)

my first test comparing jbod "simple mode" storage space vs raid0

the interesting result comes out of 4k random read & write tests. can see charts below storage spaces throughput gives out 100mb/s less raid.

my question is: expected and/or there tuning within windows server/storage spaces try , similar performance?

thanks christoph

this expected.

in short: if using low-end raid card (without cache), better switch software raid. if using mid-to-high-end card (with bbu or nvram), hardware better choice.

long answer: can found here: http://serverfault.com/questions/685289/software-vs-hardware-raid-performance-and-cache-usage

from personal experience, did lot of testing comparing storage spaces, storage spaces direct , hardware raids performance. test raid0 vs software stripe gives similar results. raid1 vs mirror , raid5 vs parity results in greater difference in favor of hardware-based raid.
