This flash is different from that of the previous-generation that we’ve seen produced by Micron. 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. COVERAGE: The plan covers all defects & malfunctions under the original manufacturer’s warranty. The plan starts the day after the manufacturer’s warranty ends. It does not cover physical or liquid damage, accessories, consumables or parts that are not covered under the standard manufacturer’s warranty. Validity : Extended Warranty will start after the Brand warranty ends & continues for 1 or 2 years as per plan. Plans valid only for products with a maximum of 2 years brand warranty. Products with more than 2 years brand warranty are not eligible. What's covered : The plan covers all defects & electric malfunctions as covered under the original Brand warranty. 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. 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. All this works in unison to provide not only lower read and write latencies and boosted throughput, but also improved reliability and endurance. Some of the storage capacity is used for formatting and other purposes and is not available for data storage. 1GB equals 1 billion bytes. Not all capacities available at initial launch.

Micron is one of the few vertically integrated SSD vendors. 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. 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. 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. But we can’t confirm any of this. Typical I/O performance numbers as measured using CrystalDiskMark® with a queue depth of128 and write cache enabled. Fresh out-of-box (FOB) state is assumed. For performance measurement purposes, the SSD may be restored to FOB state using the secure erase command. System variations will affect measured results. When installed in a Gen3 system, typical read/write speeds are 3300/2700MB/s.Calculated by comparing P5 Plus’s sequential reads of 6600MB/s to the previous generation’s (P5) speed of 3400MB/s, or to the SATA’s (BX500) speed of 540MB/s.
