[外置硬碟] WD 5TB My Passport 慢3倍 ?

問問有冇遇到 5TB My Passport file transfer 同樣的慢3倍問題 (見下面外國用家報告)

1)  5TB 我比較想要 WD 餡,但任何非 WD 牌子殼的幾乎一定是 Seagate 餡。

2)  唯有 WD 牌子殼雖唔敢講100%.,但是自家 WD 餡機會大好多。

3)  雖知道 WD 直接 Built-in Micro USB 3.0頭唔拆得,但反正如果我不打算會
拆就對我影響不大。  WD 設計或許是有得有失,唔拆得乞人憎但體積的確明顯比 Seagate Backup Plus 細d....

4)  我自己全 backup 4TB to 5TB 要 ~30小時,同下面用家報告差唔多,
但如果慢3倍要100小時則行不通根本是WD殼2019產品設計 controller 運作有問題。

Capacity: 5TBStyle: Standard EnclosureColor: BlackVerified Purchase

During last 15 years, I bought more than 10 Western Digital hard drives, both internal and external. They all worked well, I ever had only one hard drive failure, and it was after many years of service.

When I got this drive, initially I was very happy with it. It looked well constructed. It passed all self tests and external-program surface tests with flying colors. Surface tests and full formatting took a normal time for an external drive of such size (about 15 hours for full write/read surface test). However when I started backing up my data to it, it was progressing much slower than expected. Normally it takes from 20 to 30 hours to back up all my data (about 3.5T) to an USB 3 drive. It took more than 100 hours to back up my data to this drive. It looked like each file was being written with a normal speed, but there was a long wait between files, sometimes several minutes, when the drive seemingly was not doing anything. I verified that it was not my computer, or cable, or my USB port - other drives attached to the same port/cable did not experience such problem. The problem stayed consistent throughout the whole backup process. Rebooting computer or changing USB port did not help. The drive did not exhibit unusual noise or vibration, read speed was not affected, and in the end the data were written correctly.

I tried to update drive firmware, but was not successful. WD firmware updater was only saying "disconnect all USB devices except one hard drive you want to update", even though I did not have anything else connected. I was not able to get past this message.

I was seriously considering returning this drive, but in the end decided to keep it, because I need a new external hard drive, there are not many options for 5T portable drives right now, and I did not want to spend the time on testing and then backing my data on another drive. Also, as far as I can tell, whatever problems this drive has, it does not affect data reliability.
