Crucial P310 1000GB

The Crucial P310 1000GB uses the Phison PS5027-E27T controller paired with Micron 232-layer 3D QLC NAND in a DRAM-less design that leverages Host Memory Buffer (HMB). This configuration, built on a four-channel controller, can saturate the PCIe 4.0 interface and achieve read performance comparable to high-end TLC drives while offering improved power efficiency and thermal characteristics versus older controller generations.

Key Specifications

• Interface: PCIe 4.0 x4 (NVMe 2.0)
• Controller: Phison PS5027-E27T (4-channel, DRAM-less)
• NAND Flash: Micron 232-layer 3D QLC
• Sequential Read/Write: 7,100 MB/s / 6,000 MB/s
• Random Read/Write: Up to 1,000K / 1,200K IOPS
• Endurance: 220 TBW (Total Bytes Written)
• Physical Characteristics: Single-sided M.2 2280 PCB

Hardware Alternatives

• Crucial P3 Plus 1000GB: Direct architectural predecessor, moving from 176-layer QLC to 232-layer QLC and updating the controller generation.
• Corsair MP600 ELITE 1000GB: Shares the Phison E27T controller but typically uses Kioxia BiCS6 TLC NAND, which provides higher write endurance and better sustained write performance.
• Sabrent Rocket 1000GB: An updated Sabrent Rocket variant that shares controller lineage; alternatives commonly use TLC rather than QLC.
• Western Digital WD_BLACK SN770 1000GB: A high-performance DRAM-less competitor that matches peak sequential throughput while generally offering superior sustained write consistency due to TLC flash.
• Lexar NM790 1000GB: A performance competitor (Maxio MAP1602 controller) that matches peak sequential read speeds and typically delivers more consistent sustained writes because of TLC NAND.
