We Disassembled Samsung PM1725B — Enterprise PCIe x8 SSD Revealed! | ServerFlow
In this video, the ServerFlow team takes apart the Samsung PM1725B — a high-performance enterprise SSD built on the PCIe Gen3 x8 interface. Designed for data centers, this drive offers significantly better throughput and reliability compared to consumer-grade M.2 or U.2 NVMe SSDs.
We explore its internal components, including:
Samsung EPIC ARM-based 32-bit controller
16x 96-layer TLC NAND chips (K90MGY8H5A-CCK0)
9x DDR3 1866 MHz DRAM chips (K4B4G0846D-BCMA) totaling 4.5 GB of cache
Power-loss protection capacitors
A mysterious service/debug port — let us know in the comments if you know what it’s for!
We also discuss endurance ratings (up to 3 DWPD), custom firmware configurations, and how this drive can be reprogrammed to increase capacity at the cost of durability.
