Partitioning: 256GB SSD

I will partition my 256 SSD drive.

1st question: I want to know what's the minimum capacity should I leave for my Win7 operating system? I'm planning to do it 100GB for dirve C (my OS+other sooftware) and 156 for my data partition.

right now I have 500GB HDD, but my incoming laptop only have 256GB SSD....I partitioned my 500GB to 50-50 (250GB for OS and 250GB for Data partition) and my Data partition is already full (85%). So I want to maximize when I partition my new 256GB SSD.

2nd question, if I have 100GB (for drive C - which is my operating system + other software) and 80% is already full - is there any reduce in performance or speed?

 

Why do you want to partition it?

 

Because I have this very useful software called Rollback Rx - everytime I experience bad installation or corrupted software or virus or BSOD - just one click all the problem is gone.

Now if I rollback to my clean snapshot, I don't want to Rollback or included my personal file or pictures or videos - that's why I want to create a partition.

 

This is an interesting question.

Theoretically, as long as the total space on the HD is 20-30% unused, then you should be able to shrink the C: partition to just what Windows won't complain about and all should be good.

However, since we don't know how an SSD controller handles this issue, even though I only have a 100GB SSD, so far I am reluctant to partition it.

An SSD shouldn't have any problems jumping around the nand chips to get to the unused (free) memory - but theory and reality often collide right when we wished they didn't.

If you can afford the time to test it, then you'll be able to report back to us how it went. Otherwise, I would overprovision the C: (if you still want/need your rollback solution) or simply leave it as one partition.

Right now, the best way to properly partition an SSD (in my mind) is to simply have two of them and use each as a 'partition'.

Good luck.
