With emphasis on "theoretically", as most drives cannot even begin to
approach the speed of the 150 interface. Of course the maximum "burst"
speed may (or may not) benefit, but that is essentially limited to
data in the on-drive cache. Even many SSD disks have sustained
transfer rates below the SATA-150 limit.

Speed of the interface. You can use the 300 on a 150 interface. >> Stay informed about: sata-150 vs sata-300 |

The SATA-300 can theoretically transfer data twice as fast.

you can use 300 but it will run at 150 >> Stay informed about: sata-150 vs sata-300 |

The fastest drives can't even sustain half that speed of a SATA150
interface. The drive cache is really most effective on writes much more
than read. >> Stay informed about: sata-150 vs sata-300 |

The typical SSD runs in what is essentially ATA66 mode. The
crude low-end junk SSDs run somewhere between PIO mode and
ATA66. That means a range of max, peak throughput between
6-66MB/s. >> Stay informed about: sata-150 vs sata-300 |

Think of the first one as a 2 lane motorway, but your drive only needs one
lane. the second one is a 4 lane motorway, but your drive still only needs
one lane!
spec is the maximum speed of the bus, most drives can transfer at 60-70. >> Stay informed about: sata-150 vs sata-300 |
