Hi Everyone,

Can anyone advise to the following

I am needing to upgrade an old x3550 with some new HDD i am finding it a little hard to get drives as per its age and was trying to get some 300gb 15k

This machine i dont think have 15k in 300 listed but i have been advised that i can use M2 300 15k drives and change the Caddy.

My question is quiet simply is there a lot of difference that i will see

It is running at the present Windows 2008 Std and with 74GB 15k i am going to install ESXi on it and virtualize with the new HDD

The Server is used as a TS with abotu 15 Users on it

The 10K ones are very much more available so if i am not going to see a lot of difference easier to go that way but thought i would ask.

Thanks Adam

There is a different in performance between 10k and 15k disks, of approx 60 IOPS per disk. (depending upon specification of disks).

So depending upon how many disks are in the RAID set, could make a big overal difference in performance of the LUN.

I think you will see little difference.

But remember, I/O is virtualised when using a Hypervisor, so disk I/O will be less when the VM is virtual, than physical.

so always try and ensure, you create a fast as datastore as possible.
