Anyone here able to chime in on this since it appears that they went to 1.5 Gbps. Sata on the new Macbook Pro 13" model and 15" model..
Anyone buy a new one recently that can confirm??
why the switch...?
The slower SATA interface is unlikely to affect the bulk of users as even the fastest traditional hard drives are unable to saturate even the 1.5 Gbit interfaces. However, if you are planning on buying a fast Solid State Drive (SSD), it could affect the drive's performance. The downgrade of the interface in the new MacBook Pro has also been confirmed in early benchmarks using a fast enough SSD.
I thought on the new motherboards the same SATA chip is used that's used in the previous models, but it's merely capped at 1,5Gbps by software.
