My current VMware has 4 HDD running in RAID-5, with one datastore on the VM server.<br />
<br />
I will add 4 more HDD to the server. Just wonder whether there is any difference in performance if<br />
<br />
1. configure 4 new HDDs with separate RAID5 with a new datastore<br />
2. extend the current RAID with &quot;4 HDDs&quot; &nbsp;and extended the size of the existing datastore.<br />
<br />
Any comment ? Tks

Configure addition HDD on VMware server

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
