Hey guys, I was wondering how big is the difference between the Flash storage speed of 2012 and 2013 models of the retina MacBook Pro. I think Apple says it is about 30%, but is it possible to feel deference in standard everyday use (no programming, or video editing etc.)?
Got a tip for us?

Difference between rMBP 2012 SSD and rMBP 2013 SSD

Yes, but not because of the SSD. The 2012 models only have Intel HD 4000 and suffer from general lag in the UI (especially the 13" late-2012 and early-2013).
The 2013 13" rMBPs are much speedier overall, largely due to the Iris 5100 first. The SSD difference is only noticeable in I/O-intensive operations.
I've personally tried several 2013 rMBP in Apple stores, and I can tell you there is quite a bit of lag on them as well.
2012: uses a SATA-III interface (6Gbps = max throughput)
2013: uses a x2 2.0 pci-e interface (10Gbps = max throughput)
So a 2013 model can be up to 67% faster than a 2012 model. However, saturating the interface usually occurs during bulk sequential reads. Multi-queued 4k reads, as occurs during bootup or app startup, sees SSDs still not even saturating SATA-III interface limits. Meaning, a 2012 system with new 2014 SSD upgrade can 'feel' faster than a 2013 model with a stock pci-e SSD.

Hmm, not sure what lag you're talking about.
On mine at least (8gb ram, 2.6 GHz i5) there is very little lag overall. Some heavy websites do stutter with gesture scrolling (The Verge, Cnet), but overall, very smooth machine. Are you talking about UI lag? I see very little (though there is a bit occasionally).
Be honest, I couldn't tell the difference between the 2012 and the 2013 SSD in day to day use. Both were incredibly fast even when fully encrypted.
Sure if I look at benchmarks, the latter is way faster, but otherwise I can't tell the difference.
Technically it's a x4 interface for the 2013 model.
It's only at the 128GB, 256GB, and 512GB SSDs have a x2 interface; only the 1TB SSD has an x4 interface.

Yeap, talking about ui lag. Try to resize App Store, or go trough albums in iTunes, its there, and you can really feel it, especially comparing with MBA. There has been a lot of threads on the topic, such as these:

PS: I don't mean scrolling lag, I have never felt this even on heavy web sites. This was fixed with safari updates
Lag would be the wrong word for scrolling through heavy websites, I should have said that scrolling is a bit stuttery/choppy. Not buttery smooth.
