I'm using Veeam for backing up my VMs. ReFS is AMAZING with Veeam! I check with Veeam before ordering my equipment and they told me there were some issues with ReFS early on but they haven't seen any issues in quite some time and recommend they're customers use it. That said, do whatever is best in your case. For reference, here's why ReFS is incredibly beneficial for me: https://www.veeam.com/blog/advanced-refs-integration-coming-veeam-availability-suite.html

I just finished building my two new backup servers. 65 TB on ReFS 64K each.

Has anyone benchmarked using 4Kn HDDs compared to 512e HDDs? I'm looking at building a new backup server with local storage. I'm compared to storage options: Seagate ST12000NM0007 12TB 512e Seagate ST10000NM0206 10TB 4Ke While the 12TB is still cost-effective, I'm wondering which will give me the best performance. This will be installed on a Windows 2016 Standard server. My application, Veeam Backup, supports both types of drives. Dell has an article that shows a 14% performance different in IOPS between 4Kn vs 512e. I can't find much other benchmarking though. Furthermore, both drives have nearly the same specs. For example, they both have a "Max. Sustained Transfer Rate OD" of 249 MiB/s. If it makes any difference, my storage repository will consist of 8 drives connected to an LSI MegaRAID SAS 9361-8I in RAID 6. Writing large amounts of data should be more efficient (and therefore faster) on 4Kn drives, but has anyone benchmarked this or experienced this in the real world?
