Well RAID1+0 is not the best combination available. I would argue that
raid10,f2 is significantly better in a number of areas.
I'd guess Linux software RAID would be lucky to have 1% of RAID deployments
worldwide--very lucky. The other 99%+ are HBA RAID or SAN/NAS "appliances" most
often using custom embedded RTOS with the RAID code written in assembler,
especially in the case of the HBAs. For everything not Linux mdraid, RAID 10
(aka 1+0) is king of the hill, and has been for 15 years+
I wonder what sort of market penetration small cheap SAN/NAS
"appliances" have these days, aimed at the home markets and small
offices. These are almost invariably Linux md raid devices, although
the user views them as an black-box appliance.
However, though they use md raid, they typically don't support RAID10,
RAID1+0, RAID10,f2, or anything other than RAID0, RAID1 and RAID5.
