THE GM7 4TB

Unlike past GM7 models the 4TB variant comes with a somewhat thick sticker on top which has the line name on it.

This sticker is probably graphene laced to reduce temperatures from the controller and flash.

Right under the sticker we find the MAP1602 DRAM-less NAND flash controller and four 232-layer 3D TLC NAND flash modules by YMTC.

The opposite side is empty and just has a sticker with the model serial name, barcode, capacity and certifications.

Thanks to the MaXio identification software you can see some details about the drive.
