WebJun 19, 2024 · SATA-I is 1.5GHz, which means it transfers 1.5 Gbits per second. GHz and Gbits is always measured as 1Gbit = 1000000000, not as 1024x1024x1024. Since there's 10 bits per byte, not 8, we'll end up with a calculation like this: 1500000000 bits /10 bits per byte / 1024 / 1024 = 143.051147 MB/sec (not 150MB).
