Update 8/16/21 5:30am PT: Crucial has swapped out the TLC flash that powered the initial P2 SSD we tested with QLC flash, severely reducing performance. We've written an investigation into that matter, which you can read here, with our results showing that the 'new' drives are nearly four times slower at transferring files than the original, 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. That’s slower than most hard drives. Unfortunately Crucial made the change without altering the product name or number or issuing an announcement. 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. But those specs don’t match the performance you’ll see in numerous reviews of the originally-shipping drives.
As such, we do not recommend purchasing this drive. In this article, we have also inserted additional albums in each test category to reflect the real performance you'll get when purchasing this drive today.
