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 sand force controller. It's not clear that this meant a performance degradation but the customer wasn't pleased to get a product different from what was commonly reviewed.
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.
The Storage Bits take. The SSD market is brutally competitive and it's not surprising that some smaller players would seek to cut corners. But that doesn't make it right.
It is not uncommon in IT for individual components to change. A product design may take two years from conception to delivery and then sell for several years after that. In a five-year timeframe components have been known to come and go.
But in all the cases I've been involved in the company sought to do the right thing for customers: give them equal or better performance and reliability with the new component. And to make things clear they would usually update the part number as well.
That makes the Kingston substitution of asynchronous for synchronous NAND flash especially reprehensible. A customer reads a positive review, shops around, brings their shiny new Kingston SSD home, and get much less performance than they were expecting.
Sadly, this is human nature. What was the first thing that Adam and Eve did in the garden of Eden? Disobeyed orders and then lied about it.
We can't do anything about Adam and Eve but I for one will stay with more reputable brands than Kingston and PNY for SSDs in the future.
Comments welcome, as always. Have you encountered this problem?
