I am building an array with a combination of HGST HUSMM1640ASS201 eSSDs and Seagate Constellation ES.3 ST4000NM0023 4TB SAS drives.
- The SSDs are natively 4096 drives, and will let me format them either way
- The spinners are natively 512 (specs list 512, 520, 528) *BUT* it will let me format them 4096
I tried A/B with the SSDs and tested performance, no appreciable difference.
I know there could be penalties with small files and possible benefits with large one's, don't know how big the difference would be.
I don't think I have ever seen any storage device that likes being pelted with tiny files.
Anyway, is there a compelling reason here to go one way or the other that people can think of?
Thanks

- I am particularly wondering if this might be a bad thing?
- I am assuming my LSI RAID controller would not appreciate mixing different sizes in the same array (SSDs used for caching)I tried A/B with the SSDs and tested performance, no appreciable difference.
