AORUS Gen4 500GB NVMe SSD for consumers

The GP-AG4500G is an internal solid state drive built for consumer PCs that need fast storage in the M.2 2280 form factor. It uses the PCI-Express 4.0 x4 interface with NVMe 1.3 to deliver high throughput for games, applications and large file transfers. The 500GB capacity fits operating systems and active project files in a single drive.

3D TLC NAND with integrated heatsink and DDR4 cache

The drive employs 96-layer 3D TLC flash managed by a Phison PS5016-E16 controller fabricated on a 28nm process with eight channels and 32 CE targets. An onboard 512MB DDR4 cache and a pre-fitted heatsink help sustain performance during heavy workloads while keeping operating temperatures within the 0°C to 70°C range. TRIM, S.M.A.R.T., wear levelling and over-provisioning are supported for long-term reliability.

Sequential read up to 5000 MBps

These peak speeds define whether the GP-AG4500G matches the performance target of a PCIe 4.0 platform. Random read reaches 400000 IOPS and random write 550000 IOPS for responsive multitasking. Active power draw is rated at 5.9W read and 4.5W write, dropping to 13.21 mW at idle.

Questions about this item

Does the PCIe 4.0 x4 NVMe 1.3 interface cap real-world throughput at the stated 5000 MB/s read and 2500 MB/s write limits?

Yes, the Phison PS5016-E16 controller on a PCIe 4.0 x4 link with NVMe 1.3 sets the practical ceiling at the quoted 5000 MB/s sequential read and 2500 MB/s sequential write figures under ideal conditions.

What physical slot and clearance does the M.2 2280 form factor with the integrated heatsink require?

It fits a standard M.2 2280 key-M slot; the pre-installed heatsink increases the Z-height so confirm your motherboard or laptop has enough vertical clearance above the slot.

What installation step is most often missed when fitting this drive?

Removing the protective film from the thermal pads on the heatsink before securing the drive; leaving the film on blocks heat transfer and can cause throttling.
