Late 2008 Macbook only giving 1.5 gb/s speed with 6 gb/s Intel SSD?
You may find it online that this is due to the nvidia chipset used in the macbook. There is apparently a bug which causes all Intel SSDs to run at 1.5 gb/s with this chipset.
What is interesting is that I have an old HP ML115 server in the basement which was also showing the speed of the Intel SSD as 1.5 gb/s whereas another SSD from PNY was able to do 3 gb/s which is what the motherboard actually supports.
Guess what?
That server motherboard also uses an nvidia chipset. I spent the whole day tinkering with the server trying to figure out why my expensive Intel SSD is giving me 1.5 gb/s while the cheap PNY was giving me 3 gb/s. No matter what I did, it did not work - including connecting the Intel SSD to a RAID controller card and using it without RAID.
Some people have given the workaround to connect the hard drive to the CD drive connector which uses the Intel chip and not nvidia one. What I did is to put the PNY SSD from my server in the macbook. It consistently gave 3 gb/s on the server motherboard and my expectation is that it will behave the same way with the macbook as well.
The macbook with the problem was late 2008 Macbook 5,1 13 inch.
Another note, my other 2010 Macbook has no such issue with the Intel SSD.
My office PC is a 2014 machine and I was surprised to find that the SSDs which supported 6gb/s were running at 3gb/s. Turns out, only two of the ports on that Xeon workstation run at 6gb/s and they were connected to two mechanical hard drives which would never reach that speed.
I went ahead and swapped the ports. I got to say there is discernable difference between 1.5 gb/s and 3 gb/s. And also between 3 gb/s and 6 gb/s.
6 gb/s runs at the speed of thought without even a slight lag in performance. It really hums!!!
Coming back to the macbook. Yes, I can confirm it is giving me 3 gb/s with the PNY SSD and it is notably faster than before now.
