While studying for the A+ Exam I was reading about SSD's and I thought to myself that if you had a mobo with a low RAM limit you could use a dedicated SSD purely for Virtual RAM. I looked up some info on line and the info I found said that this was a poor practice but didn't explain why. Why shouldn't SSD's be used for Virtual Memory and what are your thoughts on a dedicated Virtual Memory drive? Thank you!
@Breakthrough But when you disable virtual memory, programs are killed randomly when the system runs out of memory, resulting in data loss. Virtual memory is for preventing this. – endolith – 2015-03-27T14:04:49.420
@endolith I didn't say to disable the page/swapfile. It should just be placed on another disk if possible - preferably a spinning, mechanical HDD, as they don't have a finite number of write cycles (unlike flash-based solid state drives, where using it for virtual memory would accelerate the wear on the drive). – Breakthrough – 2015-03-28T06:27:29.983
1If you can afford a SSD, I doubt your motherboard has a low RAM limit. RAM is cheaper and faster then a solid-state drive, and SSDs should NEVER be used for virtual memory!!! They have a limited number of writes, and using them for virtual memory often will severely reduce the lifespan of the drive. (Yes, I agree that they're faster then using a HDD for virtual memory, but if you're paging out even to a SSD, you're still paging out 10-20 times slower then RAM...). – Breakthrough – 2011-11-16T12:58:59.600
1I believe he's using "virtual memory" in this context to mean "RAM drive". – Bigbio2002 – 2011-11-17T16:53:56.593
2Should I keep my swap file on an SSD drive? – Sathyajith Bhat – 2011-11-28T11:39:07.183
