Unlike Adata, Crucial has kept the P2’s SSD controller the same, but swapping TLC flash for cheaper, slower, and less durable QLC can be even more detrimental to performance.Ĭhanging components in any product can happen due to a variety of reasons, like to assure component supply or cut costs, but now even the more reputable SSD manufacturers are becoming more aggressive. Sound familiar? Just as Adata has been under fire for deceptive tactics, Crucial is now in the hot seat for doing the same. But those specs don’t match the performance you’ll see in numerous reviews of the originally-shipping drives, resulting in yet another misleading component swap from an SSD manufacturer. Crucial claims that the P2 will live up to its specs because the company baked the performance of QLC flash right into the spec sheet at launch. Unfortunately Crucial made the change without altering the product name or number or issuing an announcement. For instance, the QLC version of the drive performs at roughly one-quarter the speed of the original when transferring files, read speeds are half as fast in real-world tests, and sustained write speeds have dropped to USB 2.0-like levels of a mere 40 MBps. Recently, Crucial decided to swap out the P2’s TLC flash with slower and less-endurant QLC flash, making the new P2 much worse than the original version. Crucial’s P2 wasn’t much of a contender for the title of the Best SSD when it first launched, but now it’s firmly on our do not recommend list.
