Formatting a disk for use by an operating system and its applications typically involves three different processes. [e]Low-level formatting (i.e., closest to the hardware) marks the surfaces of the disks with markers indicating the start of a recording block (typically today called sector markers) and other information like block CRC to be used later, in normal operations, by the disk ...
The Secure Digital Ultra Capacity (SDUC) format, described in the SD 7.0 specification, and announced in June 2018, supports cards up to 128 TB [b] and offers speeds up to 985 MB/s, regardless of form factor, either micro or full size, or interface type including UHS-I, UHS-II, UHS-III or SD Express.

Same build as SD/SDHC, but greater capacity and transfer speed, 32 GB and higher. Standard goes up to 2 TB (not compatible with older host devices). microSDXC: 2009 2 TB [6] Same build as microSD/microSDHC, but greater capacity and transfer speed, 32 GB and higher.

I am a bit confused over this low level format. As per this article, low level format erases all data and this data is irrecoverable. But i had a discussion with the "Geeks" of "Best Buy", who told me that there data recovery software can retrieve up to 600 GB of data (including over written one) from a 120 GB HD even if a low level format is ...
Format unit: Prepares a storage medium for use. In a disk, a low level format will occur. Some tape drives will erase the tape in response to this command. Read: (four variants): Reads data from a device. Write: (four variants): Writes data to a device. Log sense: Returns current information from log pages.

When a soft-sectored disk is low-level "formatted", each track is written with a number of bytes calculated to fit within 360 degrees at the highest expected motor speed. Special bit patterns are written right before the location where a sector should start, and serve as identifiers, similar to the punched holes used by hard-sectored disks.
