![]() All this works in unison to provide not only lower read and write latencies and boosted throughput, but also improved reliability and endurance. When compared to the company’s previous-generation 96L TLC, the new replacement gate flash replaces the polysilicon gates with metal and takes advantage of a different etching method, resulting in greatly reduced cell-to-cell capacitive coupling issues, lowered resistance levels, and allows for increased program pulse ramping. Micron’s replacement gate architecture combines both charge traps with the company’s CMOS-under array technology, allowing for a 30% smaller die size when compared to competitors’ flash. We went into detail about this new flash on our Phison PS5018-E18 preview, but for those who want the gist, instead of taking advantage of a floating gate architecture, the company’s B47R flash leverages a replacement gate architecture. This flash is different from that of the previous-generation that we’ve seen produced by Micron. There are two NAND packages on our 1TB sample, each crammed with eight 512Gb dies. Rated for interface speeds of up to 1,600 MTps, Micron’s B47R 176L TLC is some of the fastest NAND on the market. The main performance improvement behind the P5 Plus is the flash, however. You also get integrated power loss immunity due to the way Crucial programs the flash. It also sports NVMe autonomous power state transition (APST) and adaptive thermal protection that kicks in at a temperature of 80 degrees Celsius and hotter to protect data. The 500GB model and 1TB model utilize 1GB of DRAM, while the 2TB has 2GB. Regardless, the controller is still an 8-channel design that leverages LPDDR4 DRAM to accelerate FTL management. There is the possibility that the company has cut the number of cores or opted for a smaller process node to manufacture the controller, based on its lower heat output in relation to the P5. The controller is designed in-house, and we speculate that it is very similar to the six-core controller powering the P5, save for the new Gen4 PHY. But while in such a pivotal position, the company was less than forthright when it came time to open up about the hardware secrets behind the P5 Plus. 1 hi, my cpu i5-4670k, gpu - zotac 1050ti mini, mobo- gigabyte z87x-ud3h, bios version F10b, psu corsair cs650m, ram 4x4gb 1600 mhz, MX 500 500gb ssd, WD 1TB sata internal hdd, AHCI,windows10. Micron is one of the few vertically integrated SSD vendors. In terms of its performance, it’s rated to deliver sequential speeds of up to 6.6/5.0 GBps read/write and can manage upwards of 720,000/700,000 random read/write IOPS when tasked to full load, thanks to dynamic write acceleration (Crucial’s SLC caching implementation). After the second reboot, works as before. It'll reboot your machine, then you can go back and re-enable it. If you upgraded from Windows 10 without doing a clean install, you'll have to go into Storage Executive and disable Momentum Cache. At MSRPs of $107.99, $179.99, and $367.99, the P5 Plus delivers on value for sure. Crucial Storage Executive, Momentum Cache. Crucial’s P5 Plus comes in capacities of 500GB, 1TB, and 2TB and is priced aggressively low for a PCIe 4.0 SSD. ![]()
