Just confirming if i know the correct --

FAT CECHA & CECHB (hardware + card reader) have hardware based BC for the ps2, are there any other models which have the same hardware based BC with the ps2
 
Nope those are the only two models with full HW BC and these have a 98% compatibly rate. Then you have the C/E models have semi-HW and these were available in Europe. Only the US/JP got full HW PS3 trims at launch. They are about 85% when using CONFIG files to aid the SW emulation.

so means CECHEXX also has hardware based bc for the PS2.

The biggest difference is this chip, the descriptions in that links are a good resume of the differences
https://www.psdevwiki.com/ps3/CXD2953AGB
https://www.psdevwiki.com/ps3/CXD2972GB

In few words, the first retail PS3 motherboard model (COK-001) have the CPU and the GPU of the PS2
And the second motherboard model (COK-002) have the GPU of the PS2 (only graphics)

Edit:
About the card reader... take a look at this tables of components: https://www.psdevwiki.com/ps3/Talk:SKU_Models#PS3_Fat

No, thats the only, but imo from the card reader the most worthy slot was the one for the "SD" cards, the others are meh
-CompactFlash = Abandoned ? or/and expensive ?
-Memory stick = Propietary format, very expensive

Nowadays you could buy a "microSD to USB adapter" and connect it to any PS3 model. Are tiny and cheap
Edit: are also "shock resistant" and very efficient in power requirements

Whats the use of the different types cards in the card reader, can you link a site which describes the different cards slots and their uses found in the card reader.

As far i know the PS3 doesnt makes anything special with them, are just storage for general use, in OFW i guess most people was using them to store music, photos, video, etc... (the kind of content you can access from the XMB main icons)
In CFW, since some ManaGunZ versions ago, can be used to store and load game backups... are treated as another USB device

Btw, keep in mind are connected to a USB HUB... so pretty much have the same speed than the other PS3 USB connectors... or even less because the connections are like this (lets use the SD slot for the example):
Southbridge --- USB HUB --- SDtoUSB controller --- SD slot --- SD card
And in the other PS3 models, by using one of those "SDtoUSB" adaptors i mentioned like this:
Southbridge --- USB connector --- SDtoUSB controller --- SD card

As you can see we are removing a component (the USB HUB) because the newer PS3 models doesnt have a USB HUB... the 2 USB connectors are directly connected with the Southbridge

I never saw a speed comparison in between this 2 ways, anyway, they are never going to exceed the basic USB speeds because in both cases there is a "SDtoUSB controller" that needs to do the protocol conversions
