Sata III and USB 3.0

[nerdyiman]

Good evening everyone,
I wanted to know the real difference between my actual hard drive going on 5400 tr/min on SATA III and the same hard drive connected into an external box on USB 3.0
My hard drive is going on 30 to 50 MB/s on read and write.
another question, can i while replacing my hard drive with an SSD remove the SuperDrive completely from my mac, without putting anything, im not a fan of the superdrive anyway so..
thanks and sorry for my bad english

Since your Mac has a superdrive, I kinda doubt it has any USB 3.0 ports.

And SSD will fly compared to 5400 RPM HDD...

Well i have the MacBook Pro 13" mid 2012.
And my questions are :
Can i remove the SuperDrive and let the place empty ?
What is the difference in speed between USB 3.0 and SATA III on a 2,5" 5400 tr/min Hard drive ?

Last year I updated four 2010 white MacBooks for our niece and a friend. Memory when to 8GB and the HD was replaced with a Sansung EVO 840 500GB SSD. There was zero reason to remove the DVD. Those old MacBooks only did SATAII. Boot time when went from 15-20 seconds (depend on what apps were loading) to 7 seconds max. After boot, app opening when from 10+ seconds to around 2 seconds. They run Yosemite without problem.

What are you saying ?

Replace the 5400 rpm drive with an SSD and leave the DVD alone. I have seen wrecked MacBooks from folks trying to remove DVD drives. If you need an external data drive, get a 7200rpm model that should have faster read/write. Use the 5400 rpm drive for Time Machine backups where speed does not matter.

Or the WD Red. Silent and cool like a 5200/5400 rpm WD Green and fast as a WD Black (7200 rpm). I get 140 MBytes/s read and write with the WD20EFRX (make sure it has NASware 3.0 HDD firmware or newer) in this enclosure (it has the newest ASMedia ASM1153E SATA III <-> USB 3.0 UASP chip):

USB 3 for a 2tb external hard drive i'm getting 115 MB/sec plus write speed.

USB 2 maxes out at 480 megabit per second, so expecting anything more than say 40-50 megabytes per second over USB 2 is not going to happen.

Sounds like your drive is bottlenecked by the USB 2 bus.

You can remove the SuperDrive, but you don't need to.

There is no difference, the bottleneck is the 5400 RPM drive.
