Need some info in hard drives

Recommended Posts

Posted · Original PosterOP

So as you can see in the image, each hard disk has its own height, and i don't know which one is adequate for my laptop. I can't find my own hard drive specs. I was looking at the 3TB version, but it has a height of 15.5mm. I currently have a 1TB HDD, with intel Optane, and the only thing i could find is that the serial number of the hard drive is F6651718. I have tried looking this up but nothing came up. Is there anyway to find out which height I need? My computer is the Acer Nitro 5 (AN-515-52). I have also included my dxdiag.

Edit:  Wrong info.

 

You needed to look up HDD dimensions, not just height.

The 15.5mm Drives are the 3.5" full size HDDs.  The 7mm (or 7.2) are the 2.5" laptop sized ones.

No they're not.  The standard size for 3.5" drives is 146 x 101.6 x 25.4 mm, whereas 2.5" ones come in various thicknesses.  For laptops it's either 7.2mm, 9.5mm or 12.5mm, for external drives it can indeed be up to 15.5mm. 

 

Anyway,  I did a quick search for "AN-515-52 disassembly" and found a teardown guide with a video and photos of the internals, clearly showing a 1TB Western Digital Blue, a WD10SPZX to be precise.  That's a 7.2mm thick drive. 

 

 

After identifying the drive and its size, I had a quick look on my local store's site.  I can't find any 7mm drives over 2TB there either.

 

If you want higher capacity, there are 2 options :

  1. get one of the 4TB SSDs.  Unfortunately that's quite an expensive solution.
     
  2. Dremel a hole in the bottom cover exactly where the HDD sits.  That way you can install a thicker HDD which sticks out a bit.. 
    Of course you'll need to be able to live with the idea that the HDD is sticking out of the bottom.  You may also need to get some rubber feet to have the necessary clearance when putting the laptop on a flat surface. 
    The HDD itself is bolted into a HDD cradle using the side screws, and the cradle itself is mounted solidly to the chassis, so you don't have to worry about the taller HDD getting loose and falling through the hole in the bottom.

Quick google search showed 0.8 inches tall for a HDD, roughly 16mm or so.  

 

Sorry if I took  gave wrong info.

That's weird, because it's definitely 25.4mm, or 1" exactly.  I even put my calipers on one of my spare 3.5" drives to double-check.

 

No worries, the internet is full of wrong info.

This should usually be available in the specs sheet but if you cannot find it directly from the manufacturer website you should better open a ticket and contact technical support.
