You probably can't replace defective hardware so fast that the users
don't notice.  They will probably also notice when a system crash
garbles the filesystem.

Based on your comments of low cost and massive size, I presume you
can't afford a proper backup solution either.  This is a recipe for
disaster if the data is valuable.

Read the mailing lists - they are full of problems with them.  If
you value your data you will not use Sil controller.

They will be even less your friends when your cheap-n-nasty solution
loses some valuable files.
