My laptop has three disk drives, two of which are SSDs. The system drive is a 512 GB Samsung SSD 850 PRO, while the other SSD is a 64 GB Plextor M5M. Needless to say, the M5M is significantly slower than the 850 PRO, especially with writes. (Overall read and write performance are about 80% and 35% of the 850 PRO, respectively.)
The system runs Windows 8.1 Pro and has 24 GB of memory. Pagefile size is presently set to a minimum of 1 GB and a maximum of 8 GB.
While it's exceedingly rare for the system to run low on memory, this question is still relevant because some applications rely on the pagefile to function correctly regardless of the amount of physical memory available.
I'm considering placing the pagefile on the M5M. However, because Windows complains that it may not be able to save a crash dump in the event of a BSOD if there is no pagefile on the system volume, it might be a good idea to leave a small pagefile on the SSD 850 PRO. (See the proposed configuration below.)
I understand that doing this would slow paging operations due to the lower I/O performance of the M5M. The upshot of this, however, is that contention with system and application I/O on the main disk is avoided. As such, I'm not sure as to the practical performance impact when heavy paging occurs.
I'm not really worried about NAND endurance. The SSD 850 PRO has extremely high endurance because of the underlying 3D V-NAND technology, and the M5M isn't used that much.
Should I use the pagefile configuration below? What other options should I consider that might be better?
