I haven't heard of any problems with Adata in particular. I double-checked with the NUC team and they said they've used Adata mSATAs in the NUCs without issues.
Does the NUC have a thermal pad in place? If not the problem could be related to the drive overheating.
I am using the 256G version of the Adata SX300 and have not had any problems at all but it has only been a couple of weeks. But I have also not had any unexpected power loss either.
I have about 40 NUC DC3217IYE in use since 3 months. They are equiped with Adata SX300 SSD 256Gb.
Of the 40 SSD's in use I have had allready 15 of them which have failed. All NUC's are equiped with the thermal pad and the fan has been set to fixed 100%.
Is this a problem with the SSD's running to hot, or is there another problem ? My vendor talked to Adata and they asked my to firmware update the SSD's which I did but this did not help. Has anyone had a similar experience ?
I'm currently testing other brands of SSD's ( Samsung / Kingston / Micron ) to see if they also have the same problem.
