If your SATA (presumably) connection from the machine to the SSD is a 6 Gbps one, the maximum data transfer speed in bytes across that connection would be one eighth of that (as there's 8 bits per byte), so about 760 MBps. That's about half of your "1,5GBps". That makes me wonder if your SSD uses two SATA channels at once - is that even possible? Alternatively, do any SSDs compress data before sending it across the SATA channel? -- Jeremy Nicoll - my opinions are my own.
