False. Not all have money or need for SSD upgrade for older computers so they had to opt for 7mm HDs. Also there are plenty of newer regular and also other decent notebooks that still offers spinning 9.5mm HDs since SSD are still expensive option.
I wasn't referring to SSDs. Most newer spinning drive models seem to be 7mm so they aren't rare or hard to find. Many of the 9.5mm drives on Newegg are tagged with 'newer model available' and that newer model is 7mm. None of Seagate's current models are 9.5mm although WD still has a couple (and not any higher capacity than their 7mm models). I'll grant you that 7200rpm drives are disappearing because of SSDs becoming more common but you can still get 500 GB 7200rpm 7mm drives for around $50.
Not true. 9.5mm is more common at any given capacity that is the reason I gave few models that are true 7mm hard drives.
To Tankpad: are you sure you have a 7mm rubber rails?
