AORUS Gen4 2TB NVMe SSD

The GIGYTE AORUS Gen4 GP-AG42TB is a 2TB M.2 2280 internal solid state drive built for consumer desktops and laptops that support PCIe 4.0 x4. It uses 3D TLC NAND flash with 96 layers and a Phison PS5016-E16 controller manufactured on a 28nm process. The drive includes a DDR4 2GB DRAM cache and an integrated heatsink for thermal management.

PCIe 4.0 x4 interface limits

This SSD connects through a PCI-Express 4.0 x4 link using the NVMe 1.3 protocol. Sequential throughput reaches up to 5000 MBps read and 4400 MBps write, while random performance hits 750000 IOPS read and 700000 IOPS write. These figures represent the practical ceiling of the PCIe 4.0 x4 interface; a PCIe 3.0 slot will restrict speeds to that older standard.

Phison PS5016-E16 controller

The Phison PS5016-E16 controller is the component that determines whether this drive matches your workload. It provides eight NAND channels with 32 CE targets, LDPC error correction, Wear Leveling and Over-Provision technologies. Its 28nm design and DDR4 caching enable the rated 800MT/s NAND throughput and the 1.77 million hour MTBF rating.

Questions about this item

Is the 2TB capacity the right choice for a primary drive with room for large games and media libraries?

The 2TB capacity provides ample space for an operating system, frequently played titles and a sizable media collection while leaving headroom for future installs.

What do the 5000 MBps read and 4400 MBps write figures translate to in everyday use?

Those peak sequential speeds mean large game levels load in seconds, 4K video scrubs smoothly and file transfers between fast NVMe drives finish noticeably quicker than on PCIe 3.0 drives.

How does the PCIe 4.0 x4 NVMe 1.3 interface affect real-world throughput?

The PCIe 4.0 x4 link doubles the theoretical bandwidth of the previous generation, letting the Phison PS5016-E16 controller sustain the advertised 5000 MBps reads and 4400 MBps writes when the system and workload can feed it.
