I have configured the Dell R740 to use Raid 5 (mixtured of HDD/SDD storage) to run citrix xen server for VMs. In the past it was configured as Raid 1 mirroring and resulting insufficient storage. therefore we reformatted the hard disk and set it to Raid 5, the storage space is increased.

However the performance is very slow when a single VM is turned on, the navigation in Windows is very lag.

I would like to try to set the Raid to 0 if it will helps to resolve the slowness issue.

Can I do it without reformatting the hard disk? so that i do not need to backup the VM which already has multiple snapshots.

No. You will have to reformat all of the drives to change the RAID type.

The Answer is No,

Switching from RAID 5 to RAID 0 on your Dell R740 server can potentially improve performance, as RAID 0 offers better read and write speeds by striping data across multiple drives without redundancy. However, it's important to note that RAID 0 does not provide any data redundancy, meaning that if one drive fails, you could lose all the data.

While RAID 0 does not provide any fault tolerance, so it's crucial to have a proper backup strategy in place to mitigate the risk of data loss
