Enterprise-grade 1.92 TB NVMe SSD delivering up to 7400 MB/s reads and 3300 MB/s writes for data-centre workloads
The Seagate Nytro 5350M is a 1.92TB internal solid-state drive built on a PCI-Express 4.0 interface with NVMe protocol. It uses 3D eTLC memory in a 2.5-inch 15mm form factor and delivers up to 7400 MBps sequential read and 3300 MBps sequential write speeds. Random read performance reaches 1,250,000 IOPS while random write hits 90,000 IOPS, with a rated endurance of 3500TB written.
This drive targets servers and storage arrays that need high throughput and low latency for read-intensive applications. Its 1 drive writes per day endurance rating and 2,500,000 hour MTBF support continuous operation in 0 to 70°C environments. Buyers who need higher write endurance for mixed or write-heavy workloads should look at drives with a greater DWPD rating.
The single specification that decides compatibility is the PCI-Express 4.0 NVMe connection. The host system must provide a compatible PCIe slot or backplane supporting this interface and the 2.5-inch 15mm physical dimensions. Power draw reaches 14W active average and 6W idle on the 12V rail, requiring adequate cooling within the chassis.

The drive uses a 2.5 inch 15mm z-height. Most enterprise U.2 and U.3 bays accept 15mm drives, but verify your specific server tray clearance before installing.
Install the drive in a PCIe 4.0 x4 slot or an M.2/U.2 adapter wired for four lanes. A common mistake is using a PCIe 3.0 slot, which halves the available bandwidth.
The drive is rated for 3500 terabytes written. Monitor SMART percentage-used attribute; replace when it approaches 100 percent or after five years, whichever comes first.
