I'm using ESXi to host several virtual servers and I'd like to test the speed of various hard drives and protocols. (ie. I'd like to know which drive/setup works best for working operating systems)
I'm going to be comparing:
- Local SATA drive
- ZFS - RAID10 (via NFS)
- ZFS - RAID10 (via iSCSI)
- ZFS - RAIDZ2 (via NFS/iSCSI)
I'd just like to do some very simple disk benchmarks and I really like the ease-of-use of CrystalDiskMark. Is there a better alternative for simple OS drive benchmarks?
Also, can somebody explain the different numbers of these tests and what they mean?
For example, should I always use a 1 GB test? (in CrystalDiskMark)
Also, what is important for an OS drive and what is important for a storage drive? (ie. 512k speed is most important for an OS drive?)
