No longer worry about data recovery from damage to solid state drives. Samsung has recently developed a technology that can detect NAND chip failures, which can improve the life and reliability of SSDs, and announced that it will be used in the upcoming PCIe 4.0 SSD products. Samsung plans to use it in data centers first, and then consider transitioning to consumer-grade products.

This technology is called FIP (Fail in place) fault location technology, which can detect faulty NAND chips on the SSD, and avoid SSD scrapping through this operation. This technology can abolish a piece of NAND when it is broken, instead of throwing away the entire disk. Although the overall capacity of the disk is smaller, it is better than the entire disk.
FIP scans the faulty area of the storage device, and then puts the bad part of the stored data slices in other normal places. This process is completed automatically. This is a data recovery solution embedded in the SSD.
As a chip-level data recovery solution, FIP is called undead SSD by foreign media.
Generally speaking, the probability of disk damage is about one in hundreds of thousands. After it is broken, it can only be thrown away. You need to spend money to buy a new one, which will cause downtime.
How practical is it?
This technical solution is not particularly valuable on an ordinary SSD of several hundred GB, but if it is on a 30TB super-large SSD with 512 NAND, this technology is very valuable. Once the NAND chip is broken, the FIP will automatically The chip level starts the error correction algorithm.
Will such an error correction algorithm bring performance loss?
Samsung said that if it does not exist, the performance will be very stable.

Up to now, FIP technology has only appeared in two PCIe 4.0 SSDs in Samsung's data center: PM1733 and PM1735. Among them, the sequential performance of PM1735 is 14 times that of SATA SSD
