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. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
