I am hearing some high pitch noise from my Crucial MX100 SSD drive. I made sure it's not another component near the drive. It happens when the drive is in use. Changes pitch at times as well. It's faint, but there for sure. Is this normal for SSD's?
There are no moving parts in an SSD so it is unlikely to be anything mechanical, coil whine is probably the most logical answer although to prove it you will have to return it to Crucial. Best of luck!
