Bought an external hard drive ACASIS for $11.8 Aliexpress here for the operational storage of documents and videos.
Brought to St. Petersburg in 10 days by Russian post. The box was well Packed. Arrived all safe and sound. In the box was the disk cable 0.5 m manual, but only in Chinese (but it was not needed, the disk can be used immediately after connecting). All new, factory made.
The appearance is quite decent. Metal brushed case with logo ACASIS. When working flashing lights blue led. Volume a little less than 80 GB, as stated by the seller. But there are options up to one terabyte.
NTFS is just staged, there was no need to reformat. The speed is good. When connected to a USB 3.0 port, 9 GB of text documents, diagrams, videos and pictures recorded for 6 minutes.
When connected to a USB 2.0 port the speed a little lower, but not critical. When it works, hard disk ACASIS heated, sometimes very noticeable. But the work is not yet affected.
Good purchase, working. Balance of price and quality. Again, bought on Aliexpress here on this page.
