I have :

hdparm -t /dev/sdc

/dev/sdc:
 Timing buffered disk reads: 988 MB in  3.00 seconds = 329.27 MB/sec

SATA connectors for 2.5 and 3.5 drives are the same (power as well as
data). You can mount your 2.5 drive in a desktop, but if you don't have any
2.5 bays (which are available in some enclosures specifically for SSD
drives), there are kits of 2.5 to 3.5 brakets you can buy (e.g.,
http://www.newegg.com/Product/Product.aspx?Item=N82E16817994085 ).
