Using Flash Storage from Late-2013 rMBP in Mid-2015?

Hello all,

I just bought a used Mid-2015 rMBP 15 to replace my older late-2013 one but it only has 256GB flash storage. My current machine has a 512GB module and I do need this large space. I read the new flash drive should be about 4x faster than the older one so I want the speed increase but a used 512GB flash module on Ebay costs about $400 and I'm not sure if it's worth the extra cost.

I was wondering if using the slower 512GB from late-2013 in the new 2015 rMBP would be a bad idea. I believe the flash module will fit just fine, but will the speed difference noticeable in doing normal day-to-day work? Main things I do is web browsing, MS Office 2016 suite (Outlook and Excel), Windows 7 VM via Parallels and movie watching sometimes.

I will end up selling the 2013 rMBP after deciding what to do so it will have a fast 256GB flash module if I end up putting the larger drive into the new one.

Yeah I can't imagine you would notice any difference.

You should be able to just plug it in and go.

In general usage there'll be no difference.
You'll only really feel it with large file transfers, and perhaps not even then as the old SSD is probably already much faster than whichever medium you'd be transferring to/from.

Thanks for the replies!

I went ahead and swapped the flash modules yesterday. Honestly, I did not feel any differences between late-2013 and 2015 one I use now, but the touchpad is obviously different.

The 2013 won't see a speed improvement from the newer drive, but it will work just fine.
