Intel DC P3520 450GB enterprise SSD

The Intel DC P3520 is a 450GB enterprise solid-state drive built for servers and storage arrays that demand consistent low-latency performance. It uses MLC NAND and a PCI-Express 3.0 x4 interface in a 2.5 inch form factor. This drive targets administrators who need reliable mixed-workload endurance in a standard drive bay.

PCIe 3.0 x4 interface limits

The PCI-Express 3.0 x4 link caps maximum sequential throughput at 1200 MBps read and 600 MBps write, so workloads that require higher bandwidth will saturate the bus. Random performance reaches 145,000 IOPS read and 19,000 IOPS write with 20 µs latency, which suits transactional databases and virtualisation. Systems limited to PCIe 2.0 or x2 electrical width will reduce these figures further.

450GB MLC capacity decides fit

The 450GB MLC capacity determines whether the drive can hold the working set for write-intensive applications such as logging, caching or online transaction processing. Larger datasets or long-term retention needs will exceed the available space, while read-heavy archives may find the cost per gigabyte less efficient than higher-capacity alternatives.

Perguntas sobre este artigo

Should I pick the 450GB model or a larger capacity in the DC P3520 series?

The 450GB model provides up to 1200 MBps sequential read and 600 MBps sequential write. Larger capacities in the same series typically increase write IOPS and endurance, so choose based on whether your workload is read-heavy or write-intensive.

What does the 1200 MBps sequential read figure mean when the drive is installed in a server?

In a PCIe 3.0 x4 slot the drive can sustain up to 1200 MBps on large-block reads. Real-world throughput will depend on queue depth, CPU overhead and the application's I/O pattern, but the interface itself does not cap below that number.

How does the PCIe 3.0 x4 interface limit performance compared to newer standards?

The x4 lane width on PCIe 3.0 delivers a theoretical maximum of roughly 4 GBps. This drive's rated 1200 MBps read and 600 MBps write sit well within that ceiling, so the interface is not the bottleneck for this model.
