Slow speeds on Samsung T7 SSD

Hi,

 

I recently purchased a 2TB Samsung T7 SSD external hard drive for some extra storage on my Windows laptop.  It was advertised as having sequential read and write speeds of up to 1000MB/s, but I'm only getting speeds of up to 50MB/s when I try to transfer files over.

 

I've run a third party speed test and have got less than encouraging results (max 100MB/s speeds), and a benchmarker piece of software has advised it's performing in the bottom 10% of similar products.

 

I'm at a bit of a loss as to what to do, but wondered if anyone had any advice before I send it back for a refund.

 

Thanks in advance.

From Samsung  T7 web page:

* Performance may vary depending on host configuration.

To reach maximum read/write speeds of up to 1,050/1,000 MB/s, respectively,

the host device and connection cables must support USB 3.2 Gen 2 and the UASP mode must be enabled.

 

Does your laptop meet or exceed these specifications?

Hi ddaniel51,

 

Thanks for your response, appreciate it.

 

My laptop supports USB 3.1 not 3.2, but has UASP mode enabled.  Would the different USB connection make such an impact to speed?  I'd obviously expect less than the 1000MB/s advertised, but not such a significant drop as to the 50MB/s I've been experiencing!

 

Thanks.

try to simply reverse polarity by turning your :electric_plug: plug the opposite way through your outlet

For an iMac there is a conflict occasionally with reformatting the Samsung in disk utility. Reformat the T7 SSD on a Windows computer to exFAT file system. Then reformat it in your Mac to whatever file system suits. There's occasionally a conflict with the Mac I have two T7 's and one of them had trouble so it seems to be hit and miss.

Hi all. I am struggling with same problem. I tried all of them. Also update the firmware after this issue but no solution. 

There is no any damage (dropping or any physical) on the T7 Touch 2TB and also its original cable. If it is necessary but the Samsung app also works. I hope some get solved.
