The Samsung PM9E1 will be a solid-state drive in the M.2 2280 form factor, that is expected to launch in 2024. It is available in capacities ranging from 512 GB to 4 TB. This page reports specifications for the 4 TB variant. With the rest of the system, the Samsung PM9E1 interfaces using a PCI-Express 5.0 x4 connection. The SSD controller is the Presto (S4LY027) from Samsung, a DRAM cache chip is available. Samsung has installed 236-layer TLC NAND flash on the PM9E1, the flash chips are made by Samsung. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. Thanks to support for the fast PCI-Express 5.0 interface, performance is excellent. Performance characteristics of the drive are unknown.
We have no information regarding the price at release. The TBW rating for the Samsung PM9E1 4 TB is unknown, too. New information will be added to this page as soon as it becomes available.
