Question regarding SSD Optimizer.

[gameiam2008@hotmail.com]

Quick Question regarding using SSDs as a cache. What happens when 2 (or multiple people) copy files that are individually smaller than the SSD, but combine to be bigger. For example, assuming I'm using a 500GB SSD as a cache, and 2 people each simultaneously copy a 300GB file, what happens?

That depends more on how Windows handles it. 

 

WIndows Explorer (what most people use) pre-allocates the file on the destination, so that it's already using the full space on the drive.  The next file checks and will be placed on the "next" drive, in this case. 

 

So in your case, the first file would be copied to the SSD drives, while the second file would be copied to another disk.

 

 

To be honest, I wasn't 100% sure about how it was handled myself, so I tested it out with large VHD files.  Occurs exactly as described, and you can see the usage reported in the UI as this happens.
