VxRail

Anyone have experience on cache drives? compare SAS or NVMe drives? Which should I use for a better performance?

For example,

Dell 800GB, Enterprise, NVMe, Write Intensive

or  SAS

Thanks, I didn’t see this device on the validated list for those specific drives. In general, NVMe should be faster than SAS but it will depend on your workload. https://dell.to/3QLGfJS

Yes, I didn't buy the drives yet. I have discuss with sale person. I also mentioned the document that you referred. 

Thanks,
