Copy HDD 3TB On HDD 8TB, help
Hi, I use an official product of Acronis, I had had difficulties of data migration from the hard drive 3TB on the hard drive 8TB
HDD seagate 3Tb (2.5TB of data) and HDD seagate 8TB
I select item to copy a disk-> I specify 3TB and 8 TB-> I select the first item to copy 1 in 1. Further I reboot and dialogue a window акронис is started.... 4 of the 5th copying.... Waiting time 2 hours...
There pass two hours, in the program is written an hour more and so on...
As a result there have passed 8 hours the program has almost up to the end come to the end, But! Writes there were 25 sec., there passes hour, writes 14 seconds there pass 8 more hours... The program hasn't stopped copying.... The cursor of a mouse moves.
1. I want to learn how many on time the hard drive is copied by the size 3TB?
2. It is normal what copying goes 16 hours and hasn't come to the end yet?
I have seen reports about the 8TB seagate drives being unusually slow, particulalry with small files and as they fill up. However, I have also seen reports that this is no longer the case - updated model/firmware.
I have one and have not noticed it to be unusually slow (I store video fiels on it so they are all relatively lage - more than 1gig).

Yes - the 8TB drives are "archive" drives and not meant to be speedy as the shingled magnatec recording technology goal is to squeeze more on a platter and results in slower speeds....

Pros
- Increase capacity at the same density and much lower cost
- Strong read performance
- Excellent burst write speeds
Cons
- Lower performance in sustained write tests (as expected)
I have bought ST8000DM005, result copying from scratch, through a loading USB disk... The first 3-3.5 hours later process has risen for 99.9%, there have undergone 50 hours since launch copying process costs for 99.9%.
Can be to add an additional indifikation to the software Akronis to see where exactly now to be he copies copying, what file and can not" copy... Or what reason stands up to the end for 99.9% and 14 seconds what they to last 50 hours?
Than you can help me?
I plan to rewrite from 2.5TB of information 1.8TB of information. And to try to copy only programs and games which in turn occupy 500-700GB. And to look what from this vydt.

What do you think: If I allocate on a disk 3TB and in the usual way I will copy and I will insert on a new 8 TB disk, process to be dragged out for 50 hours?
Or it is what internal "a mistake copying" which didn't face yet.
50 hours for 8tb of copying to a slow 5400RPM drive with slower platter density could be realistic. 8TB is a lot of data. As different file sizes in the OS are being backed up, copy speeds will rise and fall too. Deeply nested directories and areas with many small files can be exteremely slow. I'd let it go for a while longer and see if the status changes. If it remains "hung" up for more than 5 days though, I'd say there's a problem since the progress bar appears to be nearly complete, but has not finished.
I'm not really sure that type of data you plan to copy, so it's hard to say.
