iMac external hard drive, problem consultation

by Poster Dec 12, 2019 48
[iMac (21.5-inch, 2017)] (https://support.apple.com/kb/SP758?locale = en _ CN) This computer, the built-in mechanical disk is probably exhausted. When reading and writing is good, it is 30M, and when it is bad, it is less than 10M. Therefore, if you want to connect an external solid state as the main disk, the system, software, and documents are all placed here. The reason for external connection is that the computer belongs to the company, so avoid disassembling it. I have the following questions to ask you. > Is it better to buy an external mobile solid-state drive or a desktop solid-state + hard drive box? > > Is there any recommended product, preferably one that has been tested. > > When used for a long time, will the speed be slowed down due to the temperature increase? Thunderbolt port, whether it is a hard disk box or a mobile solid-state drive, is more expensive. Therefore, the main consideration is the USB 3.1 interface.

    @ Anonymous6711 It's too bad to be unstable. I also plan, if feasible, to back up the original mechanical hard drive.

    @ Poster Good way, you can put the system in the mobile disk, it is very stable. Then use the built-in mechanical hard drive as a timemachine

    @ Poster It's done, it took two days to use it, and the speed is very fast. The speed of USB3.0 can run at full speed, writing 400MB/second, reading 410MB/second. It has been turned on continuously for about 9 hours, and there is no lag. The effect is being tested. http://lovediary.oss-cn-shanghai.aliyuncs.com/blog/source/assets/blogimage/2019-12-17 11:16:11-JpnliyMyMXm0. png

    Samsung X5, direct Thunderbolt, or low-cost, knockoff Thunderbolt hard drive case + self-purchased nvme solid-state drive: https://www.aliexpress.com/item/32952100894.html German netizens with macrumors use Mac mini, and the feedback is good.

    Samsung x5 direct Thunderbolt 3 is so fragrant that I have been using it for a long time

    @ Anonymous5251 strongly disagrees. Samsung x5 runs stably. Still heavy use.
