This is a hard disk problem. Just for reference:
The configuration recipe’s in the Storage Engine Configuration Recipes documentation has been quite enlightening, but I’m still left with some confusion.
Has anyone done a comparison of “Recipe for an SSD Storage Engine” vs. HDD Storage engine WITHOUT data in memory?
Given the same exact disks, I would like to get the flexibility of specifying files instead of raw devices. I take it aerospike needs to take a completely different approach to writing and defragging files.
And from the FAQ :
Can I store data on hard disk rather than SSD?
No. The Aerospike database is intended to be a high performance, low-latency database. Because of this, the physical limitations of rotational disks add an unacceptable amount of latency to the data.
