Hybrid SSD in GEN 8 running VMWare ESXi

Recommended Posts

If you are not going to raid the drives you would be better off with a WD Black or Velaciraptor. Another option world be for additional speed would be a true SSD for the VM boot drive (a 240 should hold about 5-6 VM boot drives) with a WD Black or red for any data held on the VM (say media for a plex server.

Thanks for the reply yodafett. I would be looking to have 4 VM's running with a footprint of about 100GB each and one VHD around 250GB for storing ISO's, WDS images and updates. ESXi currently runs from a USB stick but going to look to get it on an SSD running from the optical sata port just because I can:) I have a Synology DS412+ for media storage.

 

Currently have 4 1TB drives in a raid to give me as much space as possible but all odd and old drives while I get my setup up and running.

 

SSD would be my first option in a raid but did see the hybrid drives and thought it might be a good idea.

I'm not sure why you would want to RAID SSDs. Is it to get more total space? Is it for speed?

Yes and yes.

I think the increased storage is a fair argument. I don't think there will be any significant increase in speed because I suspect the SATA port limitations will prevent it.

Yes and yes.

What schoondoggy said.

 

Combine 4 SSD's together to turn all 4 drives in to 1 logical volume. As this will be spanned over numerous drives, this should perform quicker as far as i know.

I look forward to reading about your results. As I said, I wonder if there will be any significant increase in throughput because you will be limited by the SATA II ports.

Maximum PC tested two SSD's in RAID 0  versus a single SSD  back a few months  Here is the link to their February Posting  " PC Performance Testing" 

 

http://shar.es/1n8v10.

 

They saw only about 20 % improvement in throughput  - -  but also noticed some slowdown in the  PC mark benchmark program.

 

The main problem is whether the "trim" ( garbage collection) commands  can be passed along thru the raid controller.   

 

This is a sort of hit or miss depending on the SSD Controller and OS  but extremely important for good performance on SSD's

That's interesting Al_Borges. I hadn't considered the TRIM aspect.
