Samsung MZWLO7T6HBLA-00A07 7.68TB NVMe PCIe 5.0 2.5in Read Intensive SSD PM1743

The Samsung MZWLO7T6HBLA-00A07 is the 7.68TB 2.5-inch model of the PM1743, Samsung's PCIe 5.0 NVMe SSD for data center servers. It uses a PCIe 5.0 x4 link and is rated at 1 drive write per day, which places it in the read-intensive class.

Listed performance is up to 14,000 MB/s sequential read and 6,000 MB/s sequential write, with up to 2,500,000 random 4K read IOPS and 300,000 random 4K write IOPS. That random write figure is higher than the 3.84TB PM1743, which is typical as more flash dies work in parallel at larger capacities. The 7.68TB size suits servers that need both Gen5 speed and capacity in the same bay: AI training data and feature stores, large analytics tables, media processing scratch space and software-defined storage nodes on current Intel Xeon or AMD EPYC platforms. At 1 DWPD you can write about 7.68TB per day, so constant heavy rewriting such as write caching is better served by a mixed-use drive.

The drive needs an NVMe bay. In a PCIe 4.0 bay it will negotiate down and run at Gen4 speeds. The resellers we checked list it only as a 2.5-inch drive and do not say whether it uses the U.2 or U.3 connector, so confirm the connector and bay type with your server documentation or with us before ordering. Gen5 drives run warmer than Gen4 drives, so check that chassis airflow is rated for them. HPE, Dell and Lenovo servers also need the matching carrier and may report a generic Samsung drive as third-party.

Before you order, confirm:

• NVMe bays wired for PCIe 5.0 if you want full speed
• Connector and bay type (U.2 or U.3)
• Cooling rated for high-performance NVMe
• Daily writes within about 1 DWPD
