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
