SSD as good as old RAM?

tyler mackenzie · Dec 15, 2014

Hey All. I had a thought recently it got me thinking.

I'm currently running a 10 year old PC as my main rig. it works fine enough because I mostly just do web design. the spec sheet for my Mobo says it can only handle 4GB of Ram. and it's slow DDR2 400mhz RAM.

Here's my thought. If I got a SATA3 card for my PCI slot and plugged and fancy new SSD into that. How would it's read/write speeds compare to my old RAM sticks? because when the computer needs more than 4GB of RAM it uses swap space on the HDD normally right? would my SSD swap space be a comparable speed to my RAM?

I don't really know the technical stuff, was really just curious about that comparison.

SSD access is still orders of magnitude slower than RAM access. I also doubt that such an old PC would be able to support SSD on PCI - I think SSDs are intended for PCIe slots.

I suggest you save the money for the SSD towards a newer computer.

THere has been something in the past where Windows allows something (it's kind of vague in my mind) by plugging a USB drive in and using that for swap space.

DDR2-400 burst rate is 6400mb/s in dual channel.
This would run at a 200mhz clock. If you actually have ddr2-800 ram, which runs at 400mhz, then the burst rate would double.

So you see a pcie ssd is wicked fast bust till cannot compare to ram.
