120GB Intel 510 6G SSD Performance in MacBook Pro
Intel 510 6G SSD 120GB model
Write speed shows severe problems. Read speed is good, but well below that of the OWC 6G SSD. The 240GB model is reportedly faster (a little) than the 120GB model, but that doesn’t change the abysmal write speed. Results with incompressible data are similar, but slightly worse than with all-zeroes.
Results after the May 4 EFI firmware update for the MacBook Pro.
OWC 6G SSD 240GB
Outstanding read and write speed (speed for writing zeroes, incompressible data will be slower).
