Where is the SSD Located

Help for my Zen AiO 24 ZN242 Special Edition

Hello - My SSD crashed in my ASUS All-In-One and would like to replace it but I can’t seem to locate the SSD. This computer has a dual drives SSD / HDD I got the HDD out but can’t see where the SSD location…and the memory. Anyone?

Update (03/31/2022)

What is the exact name of this type of SSD card, I see on Amazon, Crucial sites the “one notch” cards but it’s hard to find the “2 notch”. I know the notches are not showing With this pic, but the 2 notches are located where you plug in the card. Thx

And here's the front of the card. I am seeking a replacement + 256 or as high as 512

Update (04/06/2022)

I will upload pics for the front and back sides of the card.

They may be on the backside of the motherboard. This is the case with iMacs 2012-now.

@guardian10 You were right! My issue now is trying to find the replacement SSD Card.

@sdotraffic Can you add a picture of the SSD to the question?

Hi @sdotraffic ,

Here’s a video that may help. SSD is seen at 8:00 minutes into the video

Not the exact same model as yours but hopefully it is close enough to be relevant as it also has an M.2 SSD drive.

Update (04/01/2022)

Hi @sdotraffic

Usually when inserting sata or nvme M.2 SSDs, a two keyed socket is known as a B+M socket (or slot) whereas a single keyed socket is an M socket. Other types of devices can also connect to these slots so the placement of the keys is important. See the link below for more details

A B+M card will fit into a M keyed socket but it may not work. It depends on how it is wired on the card.

An M card will not fit into a B+M keyed socket

Here's a link that explains it all

An option is to search for a B+M (insert physical size and capacity) M.2 sata SSD and ensure that it has the two keys (B + M) cutouts.

For example you could get a B+M 2280 1 TB M.2 sata SSD and it will work in a B+M slot

The card physical sizes are

2280 -- 22 mm x 80 mm. - most common size

2230 -- 22 mm x 30 mm.

2242 -- 22 mm x 42 mm.

2260 -- 22 mm x 60 mm.

22110 -- 22 mm x 110 mm

Unfortunately it seems that your model can't have nvme SSDs (for even better performance). These can be used on motherboards supporting PCIe 3.0 x4 lane and up, and are M-keyed only. Maybe the motherboard doesn't support it and that is why the slot is B+M.

@jayeff, Yes! I viewed the video and removed the motherboard - Bam! Both the SSD card and Memory were there. Thak you.

@jayeff, thank you for the explanation. I uploaded pics of the front and back of the ssd card.

@sdotraffic

It's not really that hard to find what you want.

For example, just search for an M.2 2280 500GB sata SSD and find the ones that show that they have a B+M connector in the image and chose the one you want. The same with a M.2 2280 250GB sata SSD.

The specs on your original SSD show that it is size 2280

@jayeff sounds good,, thank you for your help. I have not read that article about the B+M, but if understood you it's the card with the two notches, correct. Or is labeled B+M?

Really - thanks

@sdotraffic

Yes they're the ones with two notches.

Sometimes it is also marked on the card next to the notches but not always it seems as it is not shown on your original card, front or back. Here's an example where it does show the type. Hover your cursor over the image to zoom in and then move it to the connector end and you can see the B and M printed beside the notch

With SSDs (sata & nvme) there's no worry because the convention (at the moment anyway) is that they're either M (1 notch) or B+M. (2 notches)and not some other key (notches) or key combination - see key types in Article in my answer above.

But as I said earlier not all B+M type cards will work in an M slot even though they can be inserted. This is if you have an M slot that is, which you don't. So it is simpler just to match the card to the slot, M to M or B+M to B+M to avoid any potential compatibility problems.

Problem with all of this is you have to know what type of slot there is first before ordering the SSD, So you have to open it up to find out.

the slot type is not usually mentioned in the specs, just M.2 and perhaps that the motherboard may support an nvme SSD as well and not just sata. Although if it supports nvme it will be an M slot as that's all nvme SSD come as, at the moment anyway

Mostly reputable suppliers of SSD get it right so you don't have to check, but not in your case it seems. Although to be fair to Crucial, they don't list your model in their ram/SSD checker. The closest one - ZN242GD doesn't even mention M.2 sata SSD as an option only 2.5"sata SSD. Obviously yours is different again. Not only has it got M.2 it is M.2 B+M
