Topic: Hybrid Hard Drives

[jameswilson]

In the chase for more speed on our network im considering using 2tb seagate hybrid drives as i guess the regular files (accounts) will be on the ssd part but still give me the space i need. But im wondering if the intelligence of what is put where is part of the driver. Will these things work (raid 1) on a sme 8 and 9 server?

I don't know about SME -- but I put an SSHD into a vmware ESXi box and it works great.  The virtual SME9 system running on that box is much more responsive than my hardware-native SME 8.1 server.

Thanks for the feedback ill put a couple on but stagger the ages as i know the ssd will fail quicker

On the hybrid drives that I have used.
I have not found much speed improvement using them on workstation computers.
Also, Seagate did use some of the slower drives, 5400 RPM, on the higher volume drives with hybrid SSD.
I think they also started using the slow drives also on possibly all the drives.
I also do not think your write speed is going to be what you expect it will be.

Maybe they have improved also, I do not know.
I do not think RAID will matter.
SME really does perform well on a regular hard drive.
In my testing, network configuration and network equipment used has mattered more
on a server where SMB access is the main protocol being used.

Before you load up new drives, I would try changing the NCQ to 1, if your computer drives are set to AHCI mode, and test your performance.

Is that a sme command?
