I bought Seagates SSHD 1TB hybrid drive for my MacBook Pro. I cloned my old hard drive and tested it to ensure it was bootable, and it was. I installed it this morning in the MBP and I have noticed that now my available RAM drains in a matter of a few minutes after I boot the machine up. Any idea what would cause this?

I'm also looking to purchase a SSHD 1TB for my MBP, can you let me know if this problem has been resolved?

I don't know if you bought this, but this is the one I'm looking at buying: http://www.amazon.com/Seagate-Solid-Hybrid-2-5-Inch-ST1000LM014/dp/B00B99JUBQ/

The hard drive should have no effect whatsoever. Try putting the old one back in and run it exactly the same.

The only relationship between a hard drive and ram, is the memory uses the storage for swap files. It shouldn't, nor will it cause any decrease in ram.

The available RAM draining doesn't tell you where the issue is, posting what IS using the RAM will.

Go to activity monitor, go to the Memory tab/page and click on the top of the memory usage column to sort by largest number at the top, then screenshot that and post it.

Is it actually affecting performance? My Mac Pro says memory used 9.99gb but memory pressure is like literally none :) says File cache 5.94gb, wired memory 934mb, app memory 3.11gb

Its all being used good :D Unused ram is wasted ram
