My laptop is a Toshiba Satellite L670-1LX, bought in 2011. It originally had a HDD, but a few days ago I bought a Toshiba Q300 SSD drive. I partitioned it (aligning partitions to multiples of 2048 sectors) and cloned the OS (Ubuntu Mate 16.04) from the HDD to the SSD using clonezilla.
hdparm -t /dev/sda tests sequential read speed. on my Q300 SSD, its output is 253 MB/s (average value), whereas it could be near 550 MB/s.
- Could it be because my OS doesn't have the drivers installed to properly support my SATA 3.1 controller? As I mentioned, I did not install Ubuntu to the SSD, I just copied the HDD partition.
- Otherwise perhaps it's not a software issue and my motherboard controller can't support SATA3 at all?
I don't understand all of it, but here is the output of some commands I found on various web pages:
smartctl -a /dev/sda | grep SATA results in:
SATA Version is: SATA 3.1, 6.0 Gb/s (current: 3.0 Gb/s)
hdparm -iI /dev/sda | grep SATA results in:
Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0
lspci | grep SATA results in:
00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 4 port SATA AHCI Controller (rev 05)
