![]() ![]() The sticker design is clean and classy, but the controller IHS bubbles through, taking away from the clean looks. The finish quality on the P5’s black PCB is very good too, especially when compared to the rather rough finish of the PCB on the P2. With all components on a single side of the PCB, the P5 is compatible with almost any mobile device that fits an M.2 2280 NVMe SSD. Like WD’s Black SN750 and Samsung’s 970 EVO Plus, Crucial’s P5 comes in an M.2 2280 single-sided form factor at all capacities. The company also provides Acronis True Image cloning software so you can clone over your existing operating system and user data over to your new Crucial SSDl. This speeds performance and writes data to the drive in a less-damaging sequential manner. It can also enable/disable the Momentum Cache, which buffers random writes to the SSD in a portion of the host system’s DRAM. ![]() You use this software to update your SSD’s firmware when a new version is available, adjust the security settings, or monitor your drive. ![]() However, you can download Crucial’s Storage Executive, the company’s SSD toolbox software. Software and Accessories of the Crucial P5Ĭrucial ships the P5 bare of any accessories. The drive will not shut down until it hits roughly 85 degrees. Adaptive Thermal Protection will throttle performance when the NAND exceeds 70 degrees Celsius. Crucial’s P5 comes with AES 256-bit hardware encryption supporting the TCG Opal 2.0 and IEEE 1667 feature set and is also configurable with Windows BitLocker since it is eDrive-compliant.įurthermore, Crucial’s P5 features NVMe Autonomous Power State Transition (APST) like most competing solutions for better efficiency and there is Adaptive Thermal Protection that is linked to the temperature sensors in the NAND components themselves rather than the controller. data reporting functioned as expected, too. However, after downloading the latest 2020 version of Parted Magic, we successfully secure erase the P5 without fail. We couldn’t get the P5 to complete a secure erase with both our motherboard’s UEFI or the 2018 version of Parted Magic’s secure erase tool, at least at first. Additionally, during testing, we saw that it can simply remap its cache on the fly to ensure fairly consistent performance after hammering it time and time again, which is quite clever. It also adjusts in size not only based on the amount of capacity used, but also based on the workload so it can optimize write amplification and performance. Micron’s P5, on the other hand, retains parts of both OS and user data in portions of the cache for read requests. Most Phison-based SSDs recover their SLC cache quickly, so it acts more like a buffer. The Dynamic Write Acceleration (SLC cache) works a little bit differently than most SLC caches we have come across in the past – Crucial built some new tech into the P5. The drive also features Integrated Power Loss Immunity, but the SLC caching helps in many cases, too. The parity ratio at 2TB is 128:1, and this ratio halves as capacity halves. Additionally, Crucial also overprovisioned the P5, setting aside 9% of the overall NAND capacity for controller use, including RAIN (Redundant Array of Independent NAND), which dedicates some of the NAND strictly to parity rather than user addressable space. Similar to WD’s approach, the stronger and less efficient correction capabilities are typically used for high bit-error pages as the SSD reaches its end of life, thus optimizing for performance and efficiency during its full lifespan.įor those needing assurance on write life, these algorithms ensure that the Crucial P5 sustains up to 150TB of writes per 250GB of capacity, which is a solid 1.2 PB of writes for the 2TB model. Endurance shouldn’t be much of a concern because the P5 has a half-dozen layers of adaptation, retry, and correction in its multistep data integrity algorithms, as well as LDPC Error Correction Code (ECC). The P5 comes backed by a five-year limited warranty, or up to the rated write endurance per capacity. At the 500GB capacity point, write performance is rated for up to 1.4 GBps. All capacities can hit the read spec, but write performance degrades as capacity decreases. Crucial says the P5 delivers sequential performance of up to 3.4 /3 GBps read/write as well as up to 430,000 / 500,000 random read/write IOPS when hammered to the max. Crucial’s P5 comes in capacities of 250GB up to 2TB, and current street prices range from $0.15-$0.22 per GB. ![]()
