I want to put ssd on raid 0 using two ssd for my lab running virtual machine. I dont want to risk losing data due to ssd possible failure.

1) will virtual machine speed improve?
2) what software do i run to back up the ssd to cheap hdd? Differential backup.

Thanks

Best solution

1) I doubt you'll notice much real-world difference with RAID0 for SSD so I don't really recommend it.

2) Backup for the SSD can easily be done with Acronis True Image free version to any WD HDD (get software from WD drive section).

The 1TB WD Blue is a great drive for under $60.

3) If you still decide to do this it would likely work like THIS:

a) Create Acronis TI backup image (make sure to verify; use max compression)
b) Create the Acronis BOOT DISK to restore backups
c) Create the RAID0 array in the BIOS (recommend unhooking your HDD before this) which will destroy the data.
d) Attach the HDD again, then boot to the Acronis disk
e) Restore the backup.

You would now have a RAID0 array with the original data. If booting can't detect the OS you may need to change the Boot Order so the RAID0 setup is first.

1. If you don't wish to lose data, RAID-0 is the opposite of what you want. If you wish to improve both read and write performance at no capacity expense, go with RAID-0. If you wish to improve read performance, availability, and don't mind losing half of the capacity go with RAID-1. Both methods will improve VM read performance but only RAID-0 will improve VM write performance

2. Windows has included backup software that is reasonably good. It is different from Windows 7 to Windows 8 though.

My evga z87 classified support raids 0, 1, 5, 10 so that is good. 4 way sli.


The main idea is to run sql server, sharepoint, etc..., reasons i was thinking about raid 0. With bacup, i can easily rebuild.

So, I will be running sql server, sharepoint, visual studio solution center and maybe other intensive application. I have 32Gig of memory though, might not be enough so there might be a lot of disk swap memory into the ssd.
