How fast are the rMBP SSDs?

[cool11]

Unlike the SSD you are using just now they do not use the SATA III interface which is limited to a theoretical maximum of 600MB/s. While the SSD's in the Late 2013 rMBP's are PCI-e based which is far faster as it is essentially connected straight to the computer's data bus. I have a 512GB PCI-e SSD and see over 700MB/s for both read and write. In other words it is extremely fast and responsive, even more than your current SSD so yes it's fantastic and a definite improvement.

2012 rMBP's use SATA SSD's which transfer at around 400-500MB/s
2013 rMBP's use PCI-e SSD's and transfer at over 700MB/s (around 1000MB/s for the 1TB versions)

Any comparison of late 2013 rMBP's with early 2011 mbp?

Early-2011 MBPs share the same SATA3 bus as the 2012 ones, so the results will be exactly the same.

Hi. I'd like to ask something.

As far as I know, the 1TB SSD is faster than 512 GB SSD. I want to ask in which cases would this higher speed be noticeable?

And one more question. Which external disks do you suggest for back up for photos? Normal HDD or SSD?

I think in the real world usage there is nothing between them.

It's only noticeable in video production or I/O intensive operations.

For external drives, I stick back to several HDDs. I keep identical backup images on each HDD. SSD external drives aren't really worth it if they aren't used as a boot drive.

Here's my results on the Late 2013 rMBP (SM1024F 1TB):

My most intensive applications are Photoshop nad Ligtroom (panoramas, many layers,...) Would there be any noticeable difference between 512 GB and 1 TB SSD?

Since when did early-2013 rMBPs have a 3GHz CPU?

The fastest was only 2.8GHz, if I recall.

You are mistaken....see SS

In a later post, I did clarify that I thought that it was for 15", but turned out that the chap who posted it was referring to a 13"

No problem....It's a very quick machine...when I bought it, I really wasn't expecting it to be Logic capable, but it is...If I had a regret it would be not going for 16GB, but it rarely slows down...I use it all the time, and although it's upgrade time..I'm like the rest of us I guess...hanging out for Broadwell.
