An Overview Of Gen4 SSDs

Before we compare the P44 Pro and 990 Pro directly, let’s first understand what makes Gen4 SSDs special. Gen4 refers to drives that utilize the PCIe 4.0 interface, which essentially doubles the bandwidth compared to PCIe 3.0 SSDs. This allows Gen4 drives to reach sequential read/write speeds of up to 7,000/5,000 MB/s respectively.

In addition to raw throughput, Gen4 SSDs also offer significantly lower latency and higher IOPS (input/output operations per second). This makes them perfect for tasks like 4K video editing, 3D modeling, data analysis and other productivity workloads. The combination of speed, responsiveness and endurance offered by Gen4 SSDs enable next-level performance.

Now let’s see how the P44 Pro and 990 Pro aim to push the limits of what Gen4 SSDs can deliver.

Introducing The Solidigm P44 Pro

The P44 Pro is Solidigm’s latest flagship consumer NVMe SSD. Solidigm is a new brand spun off from Intel, focusing exclusively on data center and client SSDs. The P44 Pro aims to beat Samsung’s best by offering:

Solidigm P44 Pro
  • Sequential read speeds up to 7,000 MB/s
  • Sequential write speeds up to 6,800 MB/s
  • Up to 1.2 million IOPS for random reads
  • Support for the PCIe 4.0 x4 interface
  • Available capacities of 1TB and 2TB

The P44 Pro is the spiritual successor to Intel’s previous flagship, the 670p. It uses 144-layer TLC NAND flash and is powered by Solidigm’s proprietary SSD controller and firmware. The drive also features the latest NVMe standard (version 1.4) and has an endurance rating of up to 2,800 TBW (terabytes written).

With its excellent combination of throughput, IOPS, capacity and endurance, the P44 Pro aims to be the fastest consumer Gen4 SSD available. But the Samsung 990 Pro won’t go down without a fight, as we’ll see next.

Introducing The Samsung 990 Pro

Here are the key highlights of the Samsung 990 Pro SSD:

  • Sequential read speeds up to 7,450 MB/s
  • Sequential write speeds up to 6,900 MB/s
  • Up to 1.55 million IOPS for random reads
  • Uses PCIe 4.0 x4 interface
  • Available in capacities of 1TB and 2TB

The 990 Pro uses Samsung’s latest V-NAND flash paired with an updated custom controller.

  • 990 Pro: Up to 6,900 MB/s

Random Read IOPS

  • P44 Pro: Up to 1.2 million IOPS
  • 990 Pro: Up to 1.55 million IOPS

Random Write IOPS

  • P44 Pro: Up to 1.55 million IOPS
  • 990 Pro: Up to 1.55 million IOPS

Interface & PCIe Version

  • Both use PCIe 4.0 x4 interface

NAND Flash & Controller

  • P44 Pro: 144-layer TLC and Solidigm E20 controller
  • 990 Pro: Samsung V-NAND and Updated Samsung controller

Capacity Options

  • Both offer 1TB and 2TB options

Form Factor

  • Both use the M.2 2280 form factor

Endurance Rating

  • P44 Pro: Up to 2,800 TBW
  • 990 Pro: Up to 1,200 TBW


  • Both support NVMe 1.4, SMART monitoring, TRIM, etc.
  • 990 Pro has redesigned heatsink for better cooling

Real-World Performance Comparison

Synthetic benchmarks provide an overview of drive capabilities. But how does real-world performance compare when using these drives to boot Windows, launch games/apps or transfer files?

Several expert reviews have tested the P44 Pro and 990 Pro in real-world scenarios. Here’s a summary of their findings:

  • OS & App Loading: Both drives deliver nearly identical boot and load times. The 990 Pro was marginally faster in a couple of game launches. But we’re talking about a difference of 1-2 seconds at most.
  • File Transfers: Again, both drives are evenly matched. Transferring a 50GB game folder or 4K video files showed negligible differences. The drives maintained transfer speeds of 5,000 – 5,500 MB/s in testing.
  • Full Drive Performance: When benchmarking the entire drive capacity via tools like CrystalDiskMark, the 990 Pro scored about 2-5% higher than the P44 Pro. But this doesn’t affect real-world use.
  • Power Efficiency: Both drives are rated at 6.5W power consumption during active use. The 990 Pro supports a deeper low-power state, but this has minimal impact during everyday use.

So for all practical purposes, the P44 Pro and 990 Pro deliver equivalent real-world performance. The minor differences observed are largely academic and don’t provide a tangible benefit.
