Need help upgrading dell xps 15 notebook.

I have a dell xps 15 (l501x) notebook . It only has sata 2 (l502x has sata 3). 
I want to put a ssd hard drive in my notebook. I was thinking about 256 gb crucial or samsung ssd. 

Question # 1

Can i put a ssd with 500 mb write speed in my notebook and live with a little less speed because of sata 2 ?

Question # 2

Can i put my existing hard drive (toshiba 7200 rpm 640 gb) in a caddy in my dvd slot and obtain full speed?

Thnx in advance.



Your current HDD doesn't fully utilize the SATA 2 connection speed so you will see a boost in load times with the SSD.

Thank you for your response. Can you tell me how much of the ssd speed (500 mbs read/write) will be cut down with the sata 2 connection? About 250 mbs or so?
SATA 2 supports up to 3 Gbits/s or 3000 Mbits/s. The drive will be running at full speed.
