Chosen Solution

Hello, My SSD has just crashed (after 2 years and 4 month…) It seems that the corresponding SSD is the AData xm11 but i didn’t find a replacement easily. But does a equivalent exist ? I don’t know very well but it seems that the ones on the MacBook Air looks like quit similar. Could someone tell me which SSD i could put in my UX31A ? Thank you very much.

Hi, The ux31a has its own proprietary 18 pin connector. Only 2 hard disks were produced for this model, Sandisk U100 and ADATA XM11. Both can be found on eBay (but are quite expensive) or aliexpress (but I’m concerned about the genuinity and reliability). A good alternative is to buy an adapter, from m.2 to this 18-pin thing, so that you can buy a much cheaper m.2 ssd on your own. This is available from Chinese vendors on both amazon and eBay. I’m currently waiting for my own to arrive, but amazon reviews are pretty good. Hope this helps!

Have the similiar problem with my UX31E (mainly poor performance of the Sandisk 256GB rather than the SSD dying) and recently upgraded to a Samsung EVO 850 M.2 with a very small adapter on eBay which fits inline with the SSD. This means there is no problems with the back cover. I know alexandremadurell posted the link, but it’s well worth checking for anyone looking at changing/upgrading: https://jure.tuta.si/?p=40 There is a lot of information there and links to the different adapters including the slim-line adapter I used.

Sorry for the slow response. My boss modified the case during Christmas vacation. I haven’t seen the work myself, but he said he cut a u-shaped slit in the case near the SSD. He then bent that section out & then flat again so that it would be parallel to the rest of the case but slightly further out. He said he plans to tack weld it into place later & seal with JB Weld, but is just closing it with tape for now. I haven’t seen the results myself, but he seems to be happy with it. The bent piece still sits close enough that it doesn’t touch when the laptop is on a table, but apparently the clearance is minimal. In his words, had he known this would be the solution from the beginning, he would have settled for the OEM 256GB SSD, but having already purchased the drive & adapter, he is happy with the result. UPDATE

It appears to be a Phillips or similar. I think I just used a driver from a watch repair kit. It wasn’t installed tightly enough for me to worry too much about stripping it out.

I had a 120gb sandisk ssd in my ux31a zenbook, and it was quite slow and space wasnt nearly enough for me. So I went ahead and installed a Crucial MX300 275GB M.2 (2280) ssd using the full length adapter. In addition to that, I’ve also put some electrical tape on the back side of the cover there the ssd is just to create a “cushion” and/or barrier with it and the aluminum body. No issues since the install and very pleased. edit: You could essentially put any m.2 sata ssd, but it needs to be sata and not nvme (pcie).

I’m debating myself, which way to take. From one hand, I can find 256G SSDs with original 18-pins for about $100-120 (shipped from China). On another hand, I found an adapter (small one, without long PCB) for $10. But then I have to hunt and bid for M.2 SSDs to get it cheaper than $60-80. Plus, it should be “older” SSD that supports SATA, not just M.2…

could the new ssd M2 samsung 970 Pro also work (with adapter)?

It will be a waste even if it can. My guess it it will convert to SATA inferface & tops 550 mbytes/sec. So its pointless. there is no way such old laptop posess NVME PCIe tech which was developped much later. I wish it could because I have 3 UX31A & 1 UX32 laptops. Btw my question is similar: Would it a new NVME SSD work with UX31A or UX32 with adapters? It was said that it might not be supported by MB Bios. (UX32 uses a standard SATA SSD 7mm tall)

I am a fabricator of Custom Models and I looked long and hard to find a way to upgrade my Zenbook UX-31a to 1 Terabyte. Most people were satisfied with 256 and 500G, but not me! I have LOTS of Graphic Files and nothing less than 1 Terabyte would suffice. Finally, the Wait is OVER !!!!

. There is NOW some 3rd Party Vendors out of China that realize the significant demand for Hardware Drive Upgrades for the UX21A UX21E UX31A UX31E Zenbook platforms. You can google the following company below. I recently purchased the 1 TB made specifically for the Zenbook UX21A UX21E UX31A UX31E 500 G is now the norm for laptops and 1T will eventually be the standard. 128 and 256 Gig are no longer tollerable. I will post more about my finding after this initial post is published. NEW 1TB XM11 V2 SSD For Asus ZenBook TAICHI 21 TAICHI 31 UX21A UX21E UX31A UX31E Item priceUSD 166.99 Regards, Herman

Hi herman i bought 1 tb from this site but the problem is copying large files its take long time. in starting its copy file speed is 80-90 mb/s but after 5-10 minutes the speed is goes down 15-20 mb/s. its seems the speed getting reduce coz of heating the ssd and the speed goes low to avoid crash ssd . i had before original 128 adata ssd in my asus laptop but the space is not enough. so i bought 1tb ssd from this site. is any soloutation to bost and speed for this ssd ?

Hi shiny happy people. My father’s UX31A hard drive has died and I need to replace it. I can see that I need the m.2 to 18 pin adapter to use a standard m.2 drive, but what type of m.2 drive should I be looking at? I imagine there’s no point getting the latest as it will be too fast for the UX31a interface and will run slower, but what should I be looking for? And do I need to be wary of the length of the m.2 (with is having an adapter on it that might affect the length of it?) I’m just looking to replace it with another 256GB one (and I’m in the UK!) Thanks

Hi there,I just wanted to share, that I managed to replace the drive in UX51 using a regular SATA SSD and an adapter.Adapter: Kalea-Informatique© - adapter M.2 (M2 NGFF B Key SATA)  Disk: WDS500G2B0BThe installed disk looks like this:

(I added the electrical tape on the cover just in case).Some details of the disk here:

Hope it helps :)

I store a lot of images on my laptop and needed more space. I had to upgrade 2 times. 128G to 500G. Most recently 500G to 1TB. There is now a 1TB (1 Terabyte) option without the need for an Adapter on eBay. Just search for the UX Version along with the keyword NEW 1TB XM11 V2 SSD For Asus ZenBook TAICHI 21 TAICHI 31 UX21A UX21E UX31A UX31E

https://www.ebay.com/itm/223789789943 This solution does NOT require an Adapter, as a result, you don’t need to worry about the Thickness issue that others have mentioned. Regards Herman Bongco Modelworks Direct 1-844-8MODELS
