Hi Thomas, Those settings sound fine for your use. Write cache should be fine to leave on, the battery backup will prevent data loss in a power failure, and having the server an a UPS also will help. Disk cache should be left as default. 
Hi, I am just added 2x 16TB SATA (512e) HDD into our R440 server. They are connected to PERC H730P raid controller. I like to create a Raid 1 virtual disk for a local vmware vsphere esxi 6.7 datastore. Now i am looking for the preferred settings at the raid controller. 1. Strip Size: 1MB ? I read VMFS uses 1MB too. 2. Write Cache: ?, I am not sure performance vs. security ? 3. Read Cache: No Read Ahead ? I read for the big files like VMDK on a vmware datastore, there is no use for read ahead. 4. Disk Cache: default ? (enabled vs. disabled) Is there anything else I should take care of?   Thanks for any help. Regards, Thomas
