HDD is like having sex with a cow, doesn't feel much and can't please it, having a ssd is like having sex with a nice tight girl, aka its a good experience
Just put it this way, it takes longer for my BIOS to load up than it does for Windows.
BRING BACK BT, BRING BACK SAGA, BRING BACK VF, BRING BACK MPGHCRAFT, BRING BACK HABAMON
I run Samsung 830 128GB and a 1TB HDD.
Pretty fast.
I'd suggest using Vertex 4 with the firmware update or Samsung 840 with a HDD for movies, music etc
A SATA 3 2 TB with about 250 MB /s read/write is still cheaper than a SSD 640GB with 500 read ,550 write , witch isn't achievable (tried it on SATA 2 , on SATA 3 goes about 300 MAX) . But still a 120 GB for the OS and 640GB / 1 TB for storage and everything is perfect. From all the manufacturers ADATA and Intel are the once I tried and they do work perfect ,but still there is Corsair ,OCZ and others .
Buy Both SSD and HDD.
Install Os on SSD and use the HDD for download's and other stuff.
