This. Raw sequentials tend to be faster on higher capacity models up to a certain point (I believe 64GB might be fastest). However, I reckon majority of OS and program related tasks are mostly random in nature so it's unlikely you'll notice a difference in normal operation.That's an interesting point. But you would be very incredibly hard pressed to ever notice it during day to day usage though.
IO's will almost always be faster as the capacity gets higher but it really depends on how the flash memory is set up and what you define as much faster....It will definitely be faster to have a phone with 80GB's of space left than a phone with 0.750GB's of space left...I can say first hand that my old iPhone 4 in 16GB was always much much faster than my dads iPhone 4 in 8GB's on the same firmware update, even though my dad had far less apps on his phone and stuff running in the background he still only had 500MB's left from pictures, video, other, etc. and I also had only about 700MB's left on my iPhone 4 16GB towards the end yet it was always slightly faster. So I guess YMMV. I'll try and compare my 128GB iPhone 6 (before I transfer all my stuff) to another blank iPhone 6 in 16GB's at the Verizon store when I when I go to get my $200 gift card for my old iPhone 4 and set my dad up with my old 32GB iPhone 5c (if anyone is interested I can post here and/or PM them). Personally Its not something I would worry about if you plan to keep your phones storage no more than ~80% full or so...I generally try and go for no more than 65% to 85% full if I can but stuff happens. Not sure if this compares but with the retina MacBook Pro's the larger the flash storage the faster the speeds in terms of IO's/Read and Write speeds. I'd say its probably not worth it to go for the 128GB just for the speed if you really don't need it....I'm sure the 64GB vs the 128GB difference is miniscule in terms of speeds, and like I said before depending on the flash configuration it may vary and the 64 might even be faster than the 128GB!
Oh its way faster.
With NAND flash, increasing capacity doesn't usually increase read speeds all that much, larger capacity mostly only increases write speeds. So that means that something like app load times, boot times, etc. wouldn't be any different between the 16GB and 128GB capacity models.Yeah but does it benefit the main user in terms of multitasking or all launching?
