[Flashbench] Who is behind manfid 0x27?

Hi,

I know this is a bit off-topic, but I've recently bought a 256GB SD card with the following properties:

name: SD256 manfid: 0x000027 oemid: 0x5048 date: 05/2015 preferred_erase_size: 67108864

The device seems to support random access for up to 5 allocation units, judging from the erease-size I guess this is a TLC device. All in all the controller performs rather miserably when used as root-filesystem - I am actually a bit surprised such a weak controller is paired with flash amounting to > 40-50$.

As I have several cards with manfid 0x27 and phison controllers, I started to wonder which company is actually behind this 0x27 id?

Thank you in advance, Clemens
