Since the dimensions for an SSD should be the same for an HDD (just be
sure the SSD isn't any thicker than the HDD), I don't see why the SSD
won't fit inside the caddy used for the HDD.
But that's the problem. The SSD is 7mm typical. The drive
bays are 9.5mm or 12.5mm.
Being THINNER is okay. The mounting screw holes will still be
positioned the same on the SSD as on the HDD. The drive does not need
to fill the entire bay. The videos show the SSD getting screwed into a
cage, and it's the cage (with rubber rails pushed on) that slides into
the recess in the laptop. Unless the screws are loose, the SSD isn't
going to flop around since it isn't loose.
Width and length are fixed for the SSD to match the same-sized HDD. The
drives must fit that are the same form factor. It's only the height
that varies. So make sure the SSD isn't thicker than the HDD. Thinner
is just fine. The mounting holes in the SSD match those in the HDD.
When I go to buy an SSD, the only sizing factor by which I can choose is
different heights. Width and length are not choices. Why does the
drive bay need to get filled up because the SSD is thinner than an HDD?
No one needs a can of expanding foam sealant to fill up a drive bay.
There are 3.5" and 2.5" full, half, and low profile form factors, but
that doesn't alter width and length. Yes, a 7 mm thick SSD or HDD would
be 2 mm less thick than a 2.5" low-profile bay or cage but why does that
2 mm have to get filled up?
2.5" form factor dimensions (whether HDD or SSD or whatever drive type):
Height = 5, 7, 9.5, 12.5, 15, or 19 mm
Width = 69.85 mm
Length = 100 mm
Seems the only sizing of concern is that the SSD (new) is the same
height, or LESS, than the HDD (old).
The SSD the OP wants is, for example, listed at:
($120, free shipping)
which says the dimensions are (same for 256 GB to 4 TB models):
Height = 7 mm
Width = 70 mm
Depth = 100 mm
Samsung's own specs are at:
which uses English instead of metric measurements, which are:
Height = 0.27" (or 6.858 mm)
Width = 2.75" (or 69.85 mm
Depth = 3.94" (or 100.076 mm)
So it's a 2.5" for factored drive with 7 mm height. Apparently the HDD
in the laptop is the same 2.5" form factored drive but with 9 mm height.
So why won't a 7 mm high drive of same width and length fit into a 9 mm
bay or cage? The screw holes MUST be in the same positions; else, every
drive would need an adapter cage to fit into the standard screw
positions in the bays.
The videos show the SSD getting screwed into the cage used to hold the
HDD. Are you saying those videos are rigged and the T500 instead uses a
cage that snaps around the SSD instead of screwing onto it?
The only dimension the OP needs to watch out for is the thickness.
Since the drive cage takes up to a 9 mm high HDD, the SSD cannot be any
thicker than 9 mm. Just became Lenovo sells a 2 mm shim doesn't mean it
is required. That's for jobbers that just must stay compliant with
everything Lenovo, which means they also buy all parts from Lenovo.
That's like folks that just must get the exact same drive by brand and
model for something old, so they're willing to be a ridiculously high
storage surcharge for someone that has stored that exact brand and model
