Restore to different size drive, question about how it works

My RAID 5 is 500 GB that is partitioned as C 235GB and E 230GB where C uses 205 of the 235 partition and E uses 36 of the 230 partition.  Data takes up 241 and some of that can be moved to a spinnings disk.  When I use Acronis to do the bare metal restore, will that work if I use a 245GB SSD?   Trying to make it work with the smaller, less expensive SSD, but may need to spend more and get a 512GB?  I can't seem to find a Corsair 500GB

Can we discuss the lost block of data idea?  If I have an incremental backup and at some point realize something is wrong and it comes down to lost data, help me understand what is faulty in thinking the bare metal restore won't solve that problem. I am thinking the lost data will be on the backup, not referring to new "just created" data loss, but stored data lost due to bad blocks. Won't that stored data be on the backup and be restored in the bare metal restore?  

I would like to explore that.  I realize this may be a pointless discussion, as it may be best practice to put at least two SSD's in service in RAID 1 or 0?  Is there any reason to use some other RAID where several smaller drives equate to one larger storage space? If so, is there any redundancy in that?  I know. lots of questions. I can break these out into "related questions", if that is better.  One problem I see with SSD's expensive is gonig over 500GB gets into stupidly expensive realm for me, so wonder about some RAID configuration that could use 4 or 5 smaller SSD's to create a larger total volume. For example, 5 100GB SSDs to create the size I need?  Any benefit like redunancy in that?

Regarding the restore to a smaller drive issue, will my SBS 2008 and app and all their linking to the files and the database still be in tact? This is the thing I am trying to accomplish, to not have to go back and spend an eternity linking up all the zillions of links.  When we crashed last year it took a guy, the guy that wrote the system, about a week to get it all linked up again.  My hope in this is to have a fairly failsafe backup plan that when I bare metal restore, it all just works.  Thanks for all the input. Hope I am not driving you guys bananas. Love the input.  EE is amazing place.

Once I get comfortable with this, I plan to implement, probably next week, buy SSD(s) and test it out on a second server to see how it goes.
