6.4TB NVMe Gen4 Mixed Use SSD
The HPE P50233-B21 is a 6.4TB enterprise solid-state drive built for mixed-use workloads. It uses a PCI-Express 4.0 interface and a 2.5-inch U.3 form factor with a 15.00mm height. The drive targets database, virtualisation and analytics applications that need balanced read and write performance.
U.3 form factor and PM1735a controller
The U.3 connector provides backward compatibility with U.2 backplanes while supporting PCIe 4.0 speeds. The Samsung PM1735a controller delivers up to 200,000 random read IOPS and 310,000 random write IOPS at 4KB. Active power draw is rated at 18.7W under load.
Hot-plug install in supported servers
The 2.5-inch SFF design allows tool-less hot-plug installation in compatible HPE ProLiant drive bays. Firmware must be current on the server and storage controller to avoid detection issues. Verify that the backplane supplies sufficient power for the 18.7W rating before deployment.

Questions about this item
What is the expected write endurance limit of the 6.4TB PM1735a before the drive requires replacement?
The drive is rated for mixed-use workloads with up to 310,000 4KB random write IOPS, indicating high write endurance suitable for sustained enterprise operations.
Does the PCI-Express 4.0 interface or the 18.7W active power draw become the bottleneck during continuous heavy I/O?
The 18.7W active power consumption represents the thermal and electrical limit under sustained load, while the Gen4 interface provides sufficient bandwidth for the rated 200,000 read and 310,000 write IOPS.
How much heat and noise does the 15mm high 2.5" U.3 SSD generate when running at 18.7W all day in a server bay?
At 18.7W active power, the drive produces measurable heat requiring adequate server airflow, though solid-state construction ensures silent operation with no moving parts.
