Review on 18 TB External HDD Western Digital WD Elements Desktop, USB 3.0, black by Ha Joon ᠌

Smart shows that the disk inside is WD80EDAZ-11TA3A0. The actual rotation speed is 7200 RPM. Everywhere they write 5400 - this is not true, measured by vibration with a spectrum analyzer. Judging by the Internet, inside the disk is ordinary air, not helium. Different pros: Not SMR! I specifically ran benchmarks that write non-linearly to disk for a long time. I manually copied a lot of data to it arbitrarily in several threads. It was not possible to achieve a drop in the recording speed, as happens with SMR. Decent overall read and write speeds, under 190 MB/s. Some cons: If the disk is not specifically cooled in any way, then it heats up to 62 degrees under normal conditions. Hope it's ok for him. There is some noise and vibration. If you like to sleep in complete silence, then it is better to keep the disc in another room.
