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?
