comment How to get started troubleshooting Linux mdadm raid10 write performance?
Thanks this is a good start. I'd still like to know how to interpret things like iowait times and queue sizes, but this will get me started. After a few days of sar recording and a quick look, I suspect I have a couple of drives in the array writing much slower than the others.

Would I used Linux md RAID in a production environment? I'll point out that your could also do RAID10,f2 with the 4 SATA drives. That might do well. You really should buy both sets and test them, the return (if you can) the drives you don't end up using. Also, remember my warning about small random writes. the 'f2' part of the setup means your disks are seeking a bunch more for each write.

Are there error messages either on the console of the vmrun machine or in the log file of the ESX machine?

comment SSD redundancy via HDD
drdb is often used to get RAID1-like mirroring behavior, I would put it closer in the block-level mirroring camp than replication.
