Dear interested party, I cannot answer your question directly. I have the hard drive as a pure data storage device and this is a normal USB not a micro USB. VG

You have to connect the hard drive via usb-c anyway, and I don't know if you can save game saves, but the ps4 games are definitely saved. Whether Ps5 also works I don't know...otherwise rather expand the internal m2 memory.

These discs are identical, apart from the appearance and a software backup solution for the One Touch variant. All the enclosures contain Seagate Barracuda SATA disks. You can also open the enclosures and use the discs in other devices. The speed is also identical for all versions.

Normally, yes. However, I have made a request to the supplier, just to be sure :)

Hello Kalimpong, yes it can, it has a USB 3.0 port. To use it on a Mac, simply plug it in and reformat it briefly.

YES, a short USB3 cable is included.

Depends, did you buy a "Used+Tested" item? Then yes. Otherwise, I would contact Digitec for a replacement or a price reduction.

The write technology is not recognisable from the documentation, nor have I found any information on the internet. Seagate only keeps corresponding tables for internal hard drives. CMR could be interpreted from the following article: https://www.computerbase.de/2020-04/festplatten-seagate-smr-ohne-kennzeichnung/

~140 mb/s read and write speed. It rarely gets much faster with conventional hard disks. But this value is theoretical, it also depends on the file size. Do you have many small files (e.g. text files, Word documents, ...) or many large files (photos, films, ...)?
