With the development of SSD solid state drives today, the popularity has been very high. Even those who are new to computers know to choose solid state drives with original particles. But it’s really unreliable to only look at the original particles, because merchants have mastered the refurbishing technology, which is more than enough to deceive newcomers.
So how do merchants turn recycled inferior pellets into "original pellets"? Today we will talk about the refurbishment of Shanzhai solid state particles.
In order to reduce costs, chip manufacturers will leave the particles that fail the test on the wafer for sale. After being tested by third-party manufacturers, they will pick out the good particles, which are called "white flakes", and the remaining particles, called "black flakes", will be sold to copycat storage manufacturers.
In addition to purchasing black chips, copycat storage manufacturers will also recycle particles from damaged SSDs, sort these particles, and officially begin to refurbish "original particles".
The first is polishing. On the one hand, the quality of the pellets recycled by merchants is inconsistent with the brand. On the other hand, some of the stored pellets are specially supplied, so it is necessary to polish them to make the appearance of the pellets consistent.
The polished particles will be re-marked, and some manufacturers will put their own labels or not mark them at all. However, in order to facilitate shipment, most manufacturers will still put fake storage particle marks on them.
In addition to marking, flash memory particles also need to be tested to keep the particles in a usable state by shielding bad blocks. Some particles with poor quality will downgrade the capacity, that is, 512GB is shielded to 256GB. The quality of such particles is already very worrying.
There are also some second-hand recycled SSDs that are relatively new, so you don’t have to go through the trouble of removing the particles. You can directly flash the product’s firmware information, reset the power-on duration, and then power on for a short period of time to pretend to be a factory test, and you can transform it into a brand new solid state.
Finally, I need to remind everyone that the quality of black chips and refurbished chips is very unreliable, and SSD data is not stored continuously, which means that once one chip is damaged, all data on the disk will suffer, so don’t take chances and buy knockoff SSDs just for the sake of a temporary advantage.
Although many copycat SSDs also provide a 3-year warranty or 600TBW of reading and writing, the warranty only covers the product, not the data. Once damage occurs, you need to pay for shipping and provide proof. As the saying goes, hard drives are valuable and data is priceless. You should not trade data security for the so-called "cheapness".
