Using Samsung T7 external SSD with LrC

[OldRockyGN]

  I want to use a Samsung T7 external SSD with LrC.  That works.  My question is - can I use a

longer cable between the T7 and the computer.  And if yes - how long?  Six Feet?  As long as

the cable is USB-C to USB-C and 3.2 rated?  Will a longer cable make a noticeable difference

in terms of speed?

                                           - Thanks ... Jim

As long as you buy a really high quality cable ($$) it should be fine. The proper way is to keep your images on the external and the catalog where it is on the internal drive.

I deleted my reply. It was absolute rubish.

You can use a cable of any length that meets your requirements. The challenge (at least last time I shopped for cables) is that it’s more difficult to find longer cables that are rated to the full 10 gigabits per second of USB 3.2. You can probably make it to six feet (might be sold as a 2 meter cable) which I have, but beyond that length, you might find that cables are rated to 5Gbps; or worse, limited to the old 480Mbps of USB 2.

The main thing is that before hitting the Buy button, make sure it says 10Gbps, and for extra insurance make sure the store has an easy return policy in case it doesn’t work out.

  Additional info.  I have tried using a 6ft. cable that is USB 3.2.  Actually used it first on

just one drive and did an AV scan of the drive.  Worked and seemed 'fast'.  I then also

connected up the second T7 and copied the first one to the second one.  That also

worked and was 'acceptably fast' ... up to 98% complete ... and then 'horribly slow'

for the last 2%.  I don't know what was going on - it literally just slowed way down.

It did complete and the contents of the two drives -seem- identical (number of bytes

and number of files and number of folders all same).

  That last 2% had a lot of what looked like "windows file names" ... perhaps it was

copying the recycle bin or some such nonsense and queuing up on every file ... ???

I don't really know.

  I have 'inspected' the contents of the copied drive (2nd T7) and it all looks fine

to me - image files will open, searches by truncated file name, etc. all work.  There

really is no way to really "KNOW" without doing some kind of total file comparison.

  As to having the T7 be the drive for LrC - I think I've verified that it works just

fine with the longer cable.  LrC opens, shows all the stuff in its catalog (including

the non-destructive updates) and I can not tell the difference between the

shorter cable (supplied by Samsung with the T7) and the longer one (after

market purchase of just cables).

  I have both the catalog -and- the image files on the pSSD ... this allows me

to switch computers between my regular computer and my travel laptop

and everything is all with me all the time.  The second pSSD (T7) is only

for backups and will only be done here at home (I don't need to do

backups while I'm travelling).  What I intend to do while travelling is to

make second copies of the images I'm taking while travelling on the

HD of the travel laptop ... so I will have two copies of those.

  I'm not completely done testing these longer cables ...yet.  I intend to

do some more "are the two pSSDs the same" stuff in the next few

days.
