|There's, like, a dozen SSD optimization guides out there. Most of them boil down to:|
1) Make sure delete notify is enabled
2) Make sure defrag is disabled
3) Disable prefetching
4) Disable indexing
#1 is irreverent to traditional HDDs and can be ignored. #2 will probably happen automatically once Windows notices it's running a traditional drive. #3 should probably be enabled. #4 is up to you; if you use Windows search a lot, you should probably enable it.
Because I'm too lazy to do any real research, I pulled up a chart showing max SSD I/O operations a second and another chart showing traditional drive I/O ops a second. The high-end SSD beat the fastest spinning platter drive by a factor of 270, and the platters were spinning at 10,000 RPM, or potentially twice the rotational speed of your drive.
Is this a good comparison? Probably not; you're comparing the strength of the former to the weakness of the latter, but having your I/O take 10x longer isn't entirely unexpected. This is why SSDs cost. Prefetching and defragging attempt to turn random reads to sequential reads, so do make sure they're enabled.
