Can Lenovo T500 laptop accept a Samsung SSD to replace the HDD?

Will it fit ?

Looking at Samsung 860 PRO 256GB 2.5 Inch SATA III Internal SSD
(MZ-76P256BW) .

How do I open the T500 to do installation ?

Overview here.

Seems to use a "storage converter". Good lord, what
will they think of next.

Normal laptops, there's a cover on the bottom of the
laptop you remove, to access the drive bay.

The drive bay may be 9.5mm deep. Or on an older
machine, maybe 12.5mm or so. The list of actual
drive heights for 2.5" drives is here.

https://en.wikipedia.org/wiki/List_of_disk_drive_form_factors

5mm SSD (they only need to be as thick as a PCB+chip)
7mm Drive bay on a thin machine, but also SSD height
9.5mm Drive bay
12.5mm Drive bay
15mm WDC Passport external (not inside laptop), around 5TB max capacity
19mm No idea

SSD drives are 7mm. If there are 5mm ones, I don't
own one yet.

To keep an SSD secure in a regular drive bay, plastic
(rectangular) spacer rings can be obtained, to take
up the "slack space" and prevent the drive from
rattling around and busting off the SATA connector.

In your machine, it looks like there is an adapter
of some sort, to fulfill the same function. Your
machine appears to allow "sliding" insertion of
a drive, with one screw for retention.

You might have to go looking for an adapter, making
sure the adapter is for a 7mm drive. Then verify the
SSD is also 7mm. All of this care and attention
is intended to allow the SATA connector to mate
properly (one requirement), plus keep the drive
secure when the bay is larger than the drive
(the second requirement).

IBM Lenovo T500 Hard Drive Replacement Installation ThinkPad


That shows replacing the HDD (with another). The drive fits into a
caddy (because it slides into the case from the side) instead of just
getting inserted into a recess to hold the drive (as with a backpanel
plate to access a recess for the drive). No idea why the rubber rails
are needed. Maybe they're vibration insulators. The ribbon is a grab
handle to make easier the extraction of the drive+caddy. A recess
accessed via a backplate just has the drive sit in the recess. No caddy
required. For sliding in the drive, yeah, I can see they'd want to use
a caddy to ensure proper alignment of the drive's and laptop's
connectors. I suspect the cage keeps the drive aligned when sliding the
cage into some rails inside the laptop; however, seems there would be
some slop in alignment due to the rubber rails that slide over the cage.

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.

The video never did show the connectors on the HDD to check if they were
standard SATA connectors.



That video shows replacing the HDD in the T500 with an SSD. The cage
gets reused for the SSD, along with the rubber rails. That's what I
would expect because the SSD cases are made to the same size as the HDD
cases. Just watch for thickness of the HDD and the SSD to match.

But that's the problem. The SSD is 7mm typical. The drive
bays are 9.5mm or 12.5mm.

All the SSDs I've bought so far, *none* had the 2mm spacer.
A couple of the products, were supposed to have spacers,
and there was no spacer in the box. (A box with a sticker
type "seal".)

The rubber rails may seek to "center" the drive, rather than
reference one surface of the drive to the chassis. If the
drive slid along the plastic chassis, all you'd need is the spacer
on top to prevent it from flopping around.

If it's centered in the rubber rails, the alignment could
be off. Just a warning that the project might not go
as planned (unless you had a carrier intended for the
purpose).

Especially if (like me), the SSD box has no 2mm spacer.

And the 2mm spacer is prefaced on all (deserving) laptops
having a 9.5mm bay. If the bay was 12.5mm, chances are
the laptop would use an "old slow" processor, and a
customer (apparently) would not seek to improve
the performance of an older laptop product. So if
the bay was intended for 12.5mm, you'd need some
other kind of spacer.

If you push the assembly back into the laptop, and
it won't go in the last eighth of an inch, that
means the connector could be binding and not
capturing properly.

So this is basically a "dimensional" warning. Yes,
you can buy an SSD. Yes, the SATA connector on the
2.5" drives matches a 2.5" HDD. But if the laptop
manufacturer makes a "clever" method for mounting
the storage device, there could be challenges while
inserting it, or challenges protecting it
from mechanical shock while in there. An
unsupported SSD, if the laptop was dropped,
there's a (very small) risk the PCB could
be damaged. While SSDs nominally have a
high shock rating, this really only applies
if the assembly is well supported, so
nothing gets flexed too much.

My laptop has a metal tray and four drive screws,
and they confine the drive and provide the
correct alignment. It really needs the spacer
ring, to be fitted properly, but I've been running
it without the spacer.

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.

https://www.snia.org/forums/sssi/knowledge/formfactors

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:

https://www.newegg.com/Product/Product.aspx?Item=N82E16820147685
($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:

https://www.samsung.com/us/computing/memory-storage/solid-state-drives/ssd-860-pro-2-5--sata-iii-256gb-mz-76p256bw/?redir=MZ-76P256BW#specs

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
for decades.
