Older SSD 3GB/s vs Spinner 6GB/s Should I move the OS

Hi there
This is where I'm in a dilemma here,
I've an older SSD device (OCX 120 GB) with a transfer rate of 3GB/s and a newer 3TB spinner with a seemingly faster rate of 6GB/S.

Is it worth me removing the SSD (which I'd then use for a portable Windows to Go system with a reasonable response / performance - even if plugged into a USB 2 / USB 3 port) and move the OS to the seemingly faster spinner.

I know this goes against the grain (SSD's are usually excellent) -- and I will eventually get a new 256GB SSD. The newer SSD's are of course faster but as I have the faster spinner is it worth doing this -- it's only a 5 min job to open up the case - and moving OS'es isn't a problem --I've got enough backups and tools.

However is an OLDER SSD being outperformed by a modern 7200 rpm decent spinner. (Esata / SATA2)

Enc system info.

Well, we could start with a few basic things : 3gb/s or 6gb/s isn't a real speed, it's maximum theoretical speed of sata2 / sata3 connections, and basically very little hdds can even reach speed limit of sata1 connection, not to mention sata2 or sata3, so it matters almost only for ssd. Second, moving os from ssd to hdd will definitely slow down your os by a lot. Unless your ssd is like first ever made ssd in the world , there is no chance for hdd to be faster than ssd. I would suggest you to wait for your new ssd, and then switch to it, unless its a matter of life and death to get your windows to go system on sdd right now.

Absolutely NOT. A mechanical drive cannot saturate the bandwidth of 3Gbps, let alone 6Gbps.

The biggest benefit of an SSD is the extremely low random access times. No mechanical drive can even come close to an SSD. I would take an SSD on a SATA 1.5Gbps port, over a Raptor on a SATA 6.0Gbps port

I also don't think the HDD can use all 6GB/s bandwidth...

What does Atto Benchmark say? Would be a nice comparison between the two drives.

No spinner drive can come any where close to ssd speed. Just test the response time for each one, end of story.
