Review on 2 TB External HDD Western Digital WD Elements Portable (WDBU), USB 3.0, black by Mateusz Szlassa ᠌

CrystalDiskMark 3.0.1 x64 evaluation with a USB 3.0 port. The Sequential Value is 97.00 Sequence: 95.34 KB written; 43.86 KB read; 65.27 KB written in seq. 4k read: 0.599 Using a 4kqd32 file, I was able to write 220223 bytes and read 0.746 bytes. Only one issue arose, and it had nothing to do with this disk. On one PC running Windows 7 X64, proper device recognition was impossible due to a "lag" in the driver installation process. Simultaneously, the disk showed up in the system's device management. Everything was in working condition on another machine running the same OS. The issue was resolved after the WD SES Driver was installed on the offending system.
