I have recently replaced my DVD drive in my laptop with an optional mounting frame with a third hard drive (Samsung HDD, 1750 GB). Installation ran smoothly and the plate also works perfectly. Recently I wanted to copy an approximately 27 GB folder from my external USB 3.0 hard drive (WD Elements) to the internal HDD in the DVD drive. At first everything worked normally with approx. 80 mb / s, but at approx. 12% the data rate sank to 12kb / s and stayed that way. Even if I try again the same. When the HDD was still installed in the normal hard drive bay, everything worked perfectly. If I copy the order on my Internal M.2 SSD, the process takes about 3 minutes with 90 mb / s. Can be that the SATA connection of the DVD drive is slower than that of the hard disk?
Would appreciate an answer very much!
No, SATA is always the same. Install CrystalDiskInfo and see if the record is damaged.
Whatever may be, the disc in the DVD slot is still an HDD. If the data that you copy consists of many small files then the transfer rate will be very slow, because an HDD can't make so many small hits, which is only fast if it can read large data blocks, including large files.
Your internal SSD does not have this problem and is therefore much faster.
But still, look with CrystalDiskInfo if the plate has bad sectors. If so, you have to swap them directly.
Thanks, but when I still had it in the normal hard drive bay, everything worked fine and I was able to copy more than 100 GB in 5 minutes large order.
Again to the overview:
1) System Hard Disk (Liteon M.2 SSD, 128GB)
2) HDD for programs (Samsung 850 Evo, 250 GB - installed in the normal hard drive bay.)
3) Hard drive as a data grave (Samsung HDD, 1750 GB - installed in the DVD Lauwerk)
As I said, it makes no difference.
It is probably more of the nature of the data. Or it is defect but a SATA connector is not much slower than any other on a motherboard. That does not exist.
Have the disk now again installed in the normal bay, everything works great and I can copy a 70 GB folder with about 90 mb / s.
It's not at the shaft, that's subjective. Maybe you had only a loose cable. Maybe it was luck.
But it can't be on the shaft.
I downloaded CrystalDisk now, did not recognize anything. "Condition: good"
It may also be that it was unique. That happens sometimes.
