ExtremeTech.com has discovered that Kingston and PNY are changing the components in their SSDs once the initial reviews of their devices go online.

According to a report, one user bought a new PNY SSD expecting a Silicon Motion controller, but when they checked their new SSD found that it now had a Sandforce controller.

Another case involving Kingston they switched from synchronous to asynchronous NAND flash. This rendered the revised Kingston V300 SSD much slower than the version that was widely well reviewed.

It is not uncommon in IT for individual components to change during a product's life cycle. However,
customer should be fiven at least equal or better performance and reliability with the new component.

We have contacted both Kingston and PNY seeking for a comment.
