Does USB 3.0 matter for external enclosure for stock Macbook Pro 2012 HDD
I have a Mid 2012 Macbook Pro (9,1) and I just purchased a SSD and Im thinking of using the current 5400 rpm 500 GB hard drive as a portable external drive for media and/or back up and im trying to figure out which enclosure to get.
My concern really lies in whether or not I will get increased speeds using USB 3.0 or just stick with a USB 2.0 enclosure. I ran Black magic speed test while it was in my macbook pro and im getting around 64 MB/s write and 89 MB/s read.
The reason I ask is mainly because the reviews Ive been reading on a lot of USB 3.0 drives are mixed while there are a few USB 2.0 drives that have some great reviews and are quite inexpensive.
So will there really be that much of a real world difference between 2.0 and 3.0 Or does anyone have suggestion on which enclosures would be a good fit.
I believe the internal HDD is a Hitachi Travelstar HTS547550A9E384 according to a model search.
Any help would be great.

It does matter, since USB 2.0 only offers around 37 MB/s sequential read or write speeds, USB 3. enclosures (be sure to read up on them when researching, there is a thread about some of them being compared with an SSD and those tested almost all delivered at least S-ATA 1.5 Gbps (S-ATA I) speeds, which would be more than enough for a 5,400 RPM HDD) will be faster than USB 2.0 enclosures.

YES. It matters A GREAT DEAL.
Pick your enclosure FIRST, then find a drive to go in it.
You want an enclosure with either an
ASMedia 1051e controller chip
ASMedia 1053 controller chip.
Both of these support the new high-speed UASP (USB Attached SCSI Protocol) for faster performance on UASP capable systems.
If you are looking for a 2.5" enclosure, this one looks to be good:
Have you considered using a USB3/SATA "docking station"?
If so, check out the "stand up" and "lay-flat" docks by plugable.com (available at amazon.com)
I use a plugable.com "lay-flat" dock with an Intel 520 series SSD, attached to my Mac Mini. I get read speeds of 410mbps and writes of 247mbps. Pretty good for an external device via USB3!
