These SSDs use LDPC and an internal RAID ECC
error correction system.
This isn't the first Flexxon SSD which uses
special measures to ensure data integrity.
Even the company's low
capacity SD cards include a more called Auto Read refresh. This solves a subtle
problem which can occur in other embedded SSDs which is that ECC is typically
acticated in write mode. Auto Read refresh provides protection so that
applications which perform read operations for most of their life and duty cycle
do not build up a significant risk of uncorrectable read errors. This type of
data healing has been used for over a decade in high end enterprise SSDs but
it's unusual to see it in such small form factor drives.
positioning in the SSD market is unusual because they specialize in the
unglamorous end of the capacity and performance spectrum and focus (small
capacity and long product availability upto 10 years for some medical
custo,ers). I wrote about that in an article -
who's who in SSD? - Flexxon.
