I have RAID-1 with double WD Raptor 10.000 rpm 75GB of the year 2005, and few days before the year 2024, I did purchase two WD2005FBYZ 2TB, so this new technology to replace the old that I do own.
Both of my WD Raptors, measure today approximately 90.000 hours of the 1.200.000 of their MFTB.
I did a very in-depth read, of what WD did as steps of added technological progress to their enterprise and high-end HDD (WD Gold 2016+, WD Black 2017+, and latest of that class).
In technical terms, WD added several new technologies these relative to mechanical parts.
The new improvement’s at HDD platters rotation control, along at HDD head (mechanical actuator) both are monitored due electronic sensors.
In this new era of HDD, there is automatic control along automatic corrections made by the HDD in a split of the second for as long this is powered up.
At HDD the power down routine, HDD platters must now slow down and stop rotating within specific time, and the high precision HDD Head (mechanical actuator) this must be parked securely at it nest.
WD explains that the properly power down HDD + platters securely blocked, along Head actuator securely parked, this HDD it is now safe to be transported. (move the computer case, and or shipping).
And therefore it is expected to be generated some short of Odd noise from a HDD loaded with much more electrical systems that control platters and head.
Should I consider my Raptor of year 2005 as normal sounded HDD, and the latest High precision technology as Odd sounded?
WD it does offer product brief PDF, and even full documentation per product due Technical Reference Manual.
I am working in electronics since 1985, my first operating system Windows 95.
Today I feel ready to welcome the New Technologies’ that WD developed as improvements at what called as Modern Enterprise class of HDD.
My cash are buying:
Speed performance MB/s
Modern mechanical systems (high precision actuator, platters, motor, lots of sensors that offer several autocorrecting techniques).
HDD with secure power down sequence, this is safe for transportation as powered off.
Higher performance at RAID-1 array than a Solo HDD (back in time double HDD in RAID-1 they were running slower than single HDD).
I did read several hilarious descriptions, Odd noise, and dying cow.
These are sounds created of Fresh implemented technologies, and there is no room for personal likes and dislikes.
No one ever criticized the sound of jet airplanes VS the old one’s these using propellers.
