SATA 150 is 150MB/S transfer.
SATA 300 is 300MB/S transfer.

You will probably want to get a SATA II (SATA 3.0) drive.
Most if not all SATA II or SATA 3.0 drives are either backwards compatible immediately or they can be made so by adjusting a jumper. In other words, one of the newer SATA drives will provide the faster speeds with a newer motherboard, or revert to slower speeds with older motherboards.
There are other advantages of newer drives, including denser arrays, larger caches, and improved firmware which can provide for better performance even with older motherboard SATA150 connections.

The difference is the transfer rates. Serial ATA150 transfers at 1.5GB/s, while SATA 3.0 transfers at 3.0Gb/s. So the SATA 3.0 is twice as fast, but in order to take advantage of the speed your motherboard has to support it, else it will run at the SATA150 speed.
One last thing, please make sure you are looking at laptop hard drives, they are different then desktop hard drives, and the two are not compatible with each other.

The difference is the maximum transfer speed of the connection. SATA 3.0 is rated at a maximum of 3.0/Gbps, while SATA 150 is rated at a maximum of 1.5/Gbps. Keep in the mind, you have to have a SATA 3.0 connection on your motherboard to take full advantage of a 3.0 drive otherwise it will just transfer at the maximum speed your Motherboard can handle.
