Gigabyte GP-AG4500G AORUS 500GB Gen4 NVMe SSD

The Gigabyte AORUS Gen4 GP-AG4500G is a 500GB M.2 NVMe SSD operating on the PCIe 4.0 x4 bus, delivering up to 5,000 MB/s sequential read and 2,500 MB/s sequential write throughput — figures that require a PCIe 4.0 host to achieve but represent a genuine doubling of the PCIe 3.0 ceiling. The Phison E16 controller pairs with 512MB of external DDR4 DRAM cache and 3D TLC NAND flash: the DRAM cache is specifically what separates this drive from budget NVMe options. It stores the full logical-to-physical mapping table in fast DDR4 memory, enabling the 400K read / 550K write random IOPS figures to be maintained consistently across the drive's capacity rather than degrading under sustained mixed workloads.

This drive is appropriate as a primary system and application drive for gaming builds, content creation workstations, and professional desktops on PCIe 4.0 platforms (AMD Ryzen 5000/7000 series, Intel 12th gen and later). The 5,000 MB/s sequential ceiling fully benefits large asset transfers, game installs from large packages, and video timeline scratch performance — workloads where the bus bandwidth translates directly to wall-clock time saved. The 500GB capacity is the principal constraint: as a sole storage device it becomes space-constrained under a full game library or active media project archive, making it best paired with secondary mass storage. The Phison E16's thermal output under sustained sequential writes makes an M.2 heatsink a practical necessity rather than an optional accessory for users planning prolonged transfer sessions.
