PNY CS2340 2000GB

The PNY CS2340 2000GB uses the Phison PS5027-E27T controller, a 4-channel, DRAM-less design on a 12nm process node. It leverages Host Memory Buffer (HMB) to use system RAM for address mapping tables and is paired with high-density 3D TLC NAND, enabling high sequential throughput that approaches PCIe 4.0 saturation when the SLC cache remains available. The single-sided PCB and lower power draw make it thermally compatible with restricted-airflow environments (for example, ultrabooks or the PlayStation 5 expansion slot). Note that PNY may revise the bill of materials without changing model numbers, which can alter the specific NAND supplier, and the absence of onboard DRAM can reduce sustained random write performance under heavy, extended workstation workloads.

Hardware Alternatives

• Corsair MP600 ELITE 2000GB: Shares the Phison E27T reference design and delivers nearly identical performance characteristics.
• Sabrent Rocket 4: Specific E27T revisions exist; similar reference-design performance in some revisions.
• Inland TN470: Reference-design drive with comparable performance characteristics using the E27T architecture.
• Lexar NM790 2000GB: Uses the Maxio MAP1602 controller and offers similar peak sequential speeds and power efficiency.
• Western Digital WD_BLACK SN770 2000GB: Uses a proprietary Western Digital controller; competes in the same architectural bracket but typically tops out at lower sequential read speeds (around 5150 MB/s) compared to the CS2340.
