external-diskhard drivemacbook pro
I have a model of Retina MBP late 2013, my internal hard drive is failing and I do not want to by an ssd replacement…(quite expensive!).
I have a Sumsung MZ-750250B with a hard drive enclosure and with usb3.0 connection cable. Now could I install the OSX system into this hard drive and boot from it every time? And whether the reading and writing is fast enough?
Thank you.
Honestly, it is a waste not to have an SSD as an internal drive in a MacBook (or any computer in general), you will understand it once you have one. Of course, the speed of your internal drive has absolutely nothing to do with that of external ones. The latter is only governed by the respective bus speed they are connected to.
Absolutely - this is a good plan in general - having a bootable backup in addition to a Time Machine interval backup.
I like to get a SD card / micro SD card and install an emergency boot OS with just enough tools to fix any situation.
I would do that before making any changes. Next, you will want to measure how large your drive is - open Apple Menu - about this Mac and look in storage:
For this Mac, you would need 185 GB of space.

Yes, this is possible. For full details refer to How to set up and use an external Mac startup disk. If you have any problems, feel free to come back here and search for an answer (or ask another question if you can't find a solution).
In terms of your Samsung MZ-750250B, if you actually meant a Samsung MZ-750250GB then this is actually a SSD and supports a sequential read speed of up to 540 MB/s and a sequential write speed of up to 520 MB/s. I think you'll find this is more than enough for everyday use.
