Best controller for a system with eight SSDs?

[Levish]

Since RAM devices lose everything if they lose power, it would mean frequently copying everything back-and-forth to more durable storage, which isn't workable in my environment.

it would be a matter of setting up your backups which when implementing a server you have to do anyway. And since its a server its assumed the device only gets turned off or restarted for planned maintenance.

a couple ideas:

- vss for enabled on the Ram Disk and checking hourly and the storage used for vss set to normal disks or ssd's (this wouldn't work well for DB's).

- ntbackup full daily, differential hourly of the ram disk the differentials would overwrite so you'd only have the most recent diff and the full. Then backup again to your Tape/CD/DVD whatever for archival (this would work for DB's just setup backups for the DB and transaction logs).

Ram Disks give you the IOPs and MB/sec to do what you want, consider them if they can be made to function in your environment.

Why not after all? So at worst you'd be out about 1hr of work while getting the benefits of a Ramdisk, most smaller companies can tolerate 1 day of data loss for some services (and much less for others).
