What kind of connectors are these?

[LeLoser]

Sorry I am new to computer building and I am really confused as to what kind of these connectors those are. I know that the one on the left is the SATA but why are there 1 big and 1 small connectors. And why is there a small connector on the right.
And one more question, can anyone link me a cheap USB to SATA that can work to connect it to a laptop, a Canadian website link would be appreciated.

the large one is the power connector
the short is the data connector

I have one of these in my toolkit. you will need to provide power for drives.

1) SATA devices require two connections. The wider one is for power connection from your power supply cables. The narrow one next to it is for connection to your motherboard and your motherboard should have come with some of those SATA cables. The four-pronged connector to the right of the drive is for jumper settings depending on use (like low powered laptop vs. desktop). You don't need to worry about that.

2) I use this SATA to USB adapter for backing up my drives to another PC:

Connections from left to right are SATA power connector, Serial ATA(SATA) connector, 4 pin jumper use to enable/disable features like reduced power spinup and spread spectrum clocking, etc. Speaking of the presence of the 4 pin connector tells me this is not a SSD but HD and it's very likely a Western Digital HD because that is how they did there jumper connections.

^^You have that backwards. The wider one on the left is the power connector from the power supply. The narrow one is for connection to the motherboard. Just want to clear up any confusion he may get.
