Update 8/16/21 5:30am PT: Crucial has swapped out the TLC flash that powered the initial P2 SSD nosotros tested with QLC flash, severely reducing operation. We've written an investigation into that affair, which y'all can read here, with our results showing that the 'new' drives are nearly 4 times slower at transferring files than the original, read speeds are half as fast in real-earth tests, and sustained write speeds have dropped to USB 2.0-like levels of a mere 40 MBps. That'south slower than most hard drives. Unfortunately Crucial made the change without altering the production name or number or issuing an annunciation. Crucial claims that the P2 will alive upwardly to its specs considering the visitor broiled the performance of QLC flash right into the spec sheet at launch. Merely those specs don't match the operation you'll see in numerous reviews of the originally-shipping drives.
Equally such, we do not recommend purchasing this bulldoze — instead, consult with our latest recommendation in our Best SSDs article. In this article, nosotros accept also inserted boosted albums in each test category to reflect the real performance you'll get when purchasing this drive today.
Original article :
Crucial's P1, the company'southward first M.2 NVMe SSD, was a bit of a disappointment with tedious performance and amidst the everyman endurance specifications on the marketplace. It surely didn't scream value equally we had hoped information technology would. Crucial'southward new P2 aims to exist a better value with Phison's entry-level E13T NVMe SSD controller and Micron'southward latest 96-Layer TLC flash under the hood, though. Crucial's P2 may not exist the Best SSD on the market, but information technology offers multi-gigabyte throughput at low toll points, blowing SATA SSDs out of the water.
The SSD market place is quite crowded, and if y'all're on the hunt for a new SSD for your system, you probably detect there are innumerable options. If you've got the dough, you may want to consider one of the newest PCIe iv.0 x4 options, say the Seagate FireCuda 520 or Sabrent's Rocket NVMe four.0. Simply, if you're a bit strapped for cash, and so one of the many low-toll SSDs, like Crucial's MX500 or P1, might be upward your alley…until y'all suddenly realize that Crucial'south new P2 is now available, potentially offering significantly more operation at the same price. Overall, the P2 is perfect for a cheap 1000.2 NVMe boot bulldoze, making it a clear contender for the top spot amongst value SSDs, but it appears Crucial will make the bulldoze with a variable build of materials, pregnant the internal components could change over time. That means you'll need to do your enquiry before y'all plunk down your difficult-earned dollars.

Crucial's P2 is the visitor's latest M.2 NVMe SSD for the low-upkeep crowd. In fact, the P2's pricing might cannibalize the visitor'south MX500 sales just as much as information technology competes with other companies. The 250GB and 500GB capacities are well-suited for basic boot and application requirements, but although Crucial lists a 1TB SKU, it isn't available at the time of publishing. The entry-level P2 SSDs are priced at $50 for the 250GB model and just $65 for the 500GB model, though.
The P2 features Dynamic Write Acceleration, which essentially programs a pool of TLC flash every bit faster SLC for faster write performance. Afterward it fills, write performance will dethrone, which we volition cover in greater item on the next page. Crucial rates the P2 to deliver sequential performance of up to 2.4/1.eight GBps read/write and up to 170,000/260,000 read/write IOPS, simply functioning suffers a flake with the smaller 250GB and 500GB capacities. The 500GB'south sequential write functioning is even rated below the 250GB model at just 940 MBps.
The drives come with RAID ECC and Phison'southward fourth-gen LDPC that has multiple levels of adaptation. As a result, Crucial's P2's endurance ratings, though they are low for TLC SSDs, aren't as offensive as some of the QLC SSDs nosotros've looked at. The company rates the 250GB P2 up to 150TB of writes within its five-year warranty, and adds another 150TB of write endurance with each doubling of capacity.
Crucial P2 Software and Accessories
The drives come up with Crucial's SSD Toolbox, Storage Executive, and Acronis True Prototype (via download). Crucial Storage Executive is quite handy and characteristic-packed. With it, you can optimize performance, manage data security, or even merely update the firmware, among other features. Acronis True Prototype for Crucial lets y'all clone your data or brand system images for free as long equally y'all have a Crucial SSD plugged in, just some of the backup features aren't included unless you buy the full version.
A Closer Look at the Crucial P2
The Crucial P2 comes in an One thousand.2 2280 form factor. The PCB is black, but the quality of the finish is rather defective. The edges of the Grand.2 lath are rough, and unlike other SSDs, the black end doesn't make it all the mode to the edges..
The P2 interfaces with the host over a PCIe three.0 x4 link with the Phison E13T, a DRAMless 4-channel NVMe 1.3 SSD controller. Phison fabs the E13T on the 28nm process node and the scrap operates at 667MHz. The controller is a single-core blueprint with a coprocessor optimized for NAND management chore offloading. Speaking of which, there are four NAND packages on our 500GB P2, with 9% set aside equally factory overprovisioning for groundwork tasks like bad cake management and garbage collection. Each package contains two dies of Micron's latest 512Gb 96-Layer TLC flash that interface with the Phison E13T NVMe controller at 800MT/s.
The P2 lacks DRAM, meaning that it doesn't accept a fast buffer space for the FTL mapping tables. Instead, the P2, like most modern DRAMless NVMe SSDs, uses NVMe'southward Host Memory Buffer characteristic. With it, the SSD can use a few MB of the host system's retentiveness to provide snappier FTL access, which improves the feeling of 'snappiness' when y'all utilise the drive.
Additionally, the controller supports APST, ASPM, and L1.2 power saving modes for better power efficiency in mobile devices. There's an adaptive thermal throttle protection congenital-in, then if the controller and NAND go too hot (70 degrees Celsius), the SSD will throttle performance or even shut downward (85C), so information technology doesn't damage data. Furthermore, the P2 comes with integrated power loss 'amnesty,' and so data is fairly protected in the example of a ability outage. The controller likewise supports Southward.K.A.R.T. data monitoring, TRIM, and secure erase capability to completely wipe the data make clean off it, as well.
