Will the WD Blue 1TB Laptop 7mm Hard Drive: 2.5 Inch, SATA 6Gb/s, 5400 RPM, 8MB Cache WD10SPCX work with a lenovo y50?

Not Compatible. The Y50 HDD is specified as a 7mm thick. The HDD you show is 9.5mm thick.

There could be internal interference. Https://download.lenovo.com/consumer/mob... http://www.seagate.com/internal-hard-dri... http://www.seagate.com/internal-hard-dri... The Y50 is specified as 5400 rpm HDD. That is not to state a 7200 rpm will not work, but there is a chance there is insufficient power.

That is not usually critical. Additional concern is the recovery of Windows and drivers, normally as a clone off a working HDD. And, the Y50, like many Lenovo laptops use Nylok Coated screws and are supposed to be replaced if removed.

It's 2.5" form factor, the same with all laptops. I believe your laptop is SATA connection, so any brand or any type of SATA HDD or SSD or SSH is interchangeable.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
