Read/Write Speeds on macbook pro

[amgclk65]

Hello forums members. I installed a force 3 120gb, in my 2011 macbook pro 13.3 i5. heres my read and write speeds via aja system test!

Should i be getting 550 speeds?

Probably not, it depends on the Chipset the Macbook is using and if it supports SATA III 6GB/s. In this case yes the chipset does support SATA III 6GB/s.

 

I'd say the speeds are normal.

Those numbers are great. You can't compare those figures to ATTO, unless you know that AJA uses compressible data like ATTO does. The SandForce controller on your SSD uses a technique to gain additional speed by compressing data, but not all data can be compressed, so the speed is reduced somewhat. If AJA uses only some or no compressible data, than your results are great. Even if they do use all compressible data, laptops are not up to the standards of the best desktop PCs, so you may not reach the very top speeds. The spec for your and any SSD is, "up to... MB/s", not exactly that speed.

 

Also, any SSD does not have a single speed of data transfer for every size file or blocks of data. They are usually fastest with very large files and slower with smaller ones.

amgclk65, do you want to try testing your ssd speeds using blackmagic disk speed test and posting your results? i ran mine on it and i am only getting 130mb/s write speeds. I'm using macbook pro 2010 on SATA II though.

Do that test wouldnt tell anything, as you 2 use different controllers and Controller is one of the key things in this.

 

Example, Intel's controller get ~200mb/s higer speeds(read and Write) then AMD's controller.
