With today’s Flash storage devices, the legacy block sorting function used in previous data reconstruction is no longer adequate due to the reasons listed below. Sorting must now be performed in units of multiple sectors, most commonly 8 sectors (4096 bytes):
TLC/QLC flash memory suffers drastically reduced reliability, which demands fine-grained bad block management at the sector level.
Multi-Bank parallel architectures have become mainstream, requiring fine-grained sector splitting to maximize read/write performance.
Optimizations for FTL page mapping and garbage collection reduce write amplification and extend flash lifespan.
Logical alignment of host LBAs, to conform to the standard disk sector model used by PCs.
Fragmented storage requirements for encryption information, serial numbers (SN), firmware logs, and OOB metadata.
This shift in sorting units can cause the volume of objects to be sorted to surge from several thousand to tens of millions. As a result, most existing software either lacks full sector sorting support or only works with one or two specific controller types.
NFT has undergone in-depth development to address this challenge. Its sector sorting feature features customized solutions tailored to the characteristics of various controllers. It now delivers comprehensive sector sorting compatibility covering the vast majority of controllers from the brands below, with support for hundreds of unique sector sorting variants in total:
Sandisk
SiliconMotion (SM)
AlcorMicro (AU)
Innostor (IS)
Asolid (AS)
JMicron (JM)
Silicongo (SG)

I use large numbers of hard disks for SSD backup for the reasons I have seen so many dead ones in my studio

Yes, this situation does exist. We are also developing features related to SSDs and have achieved groundbreaking progress. We will make an official announcement at a later date.
