The AGI AI818 1TB SSD features an M.2 2280 form factor, PCIe 4.0 x4 communication, NVMe 1.4 specification, and 3D TLC NAND flash memory, backed by a 3-year warranty. For computers designed for entry-level document handling and online installations, using a PCIe 4.0 SSD as the system disk not only delivers higher read and write bandwidth to meet the system’s frequent IOPS demands but also ensures faster access speeds, resulting in smoother computer operation.

The SSD is designed with components on one side only, while the backside simply features safety stickers.

Once the front label sticker is removed, the AGI AI818’s internal components can be seen, including the MAXIO MAP1602 SSD controller and four 3D TLC NAND flash memories that work together to provide a 1TB capacity.


The provided AGI heatsink features a 3M heat-conducting adhesive on its back. During DIY assembly, it is recommended that users utilize the M.2 heatsink present on the motherboard. In cases where the motherboard lacks a built-in heatsink, the AGI heatsink can be used instead to provide better temperature control for the SSD.

AGI AI818 1TB NVMe PCIe 4.0 SSD performance test

The test was conducted using an AMD Ryzen 9 7950X processor and a ROG CROSSHAIR X670E HERO motherboard, with the AGI AI818 1TB NVMe PCIe 4.0 SSD installed in the first M.2 slot of the motherboard using the motherboard’s heatsink for testing purposes.

The AGI AI818 1TB NVMe PCIe 4.0 SSD was inspected using CrystalDiskInfo, revealing its adoption of PCIe 4.0 x4 and NVMe 1.4 interfaces and support for SMART, TRIM, and VolatileWriteCache functions. The actual usable capacity after formatting was found to be 953GB.

Usable capacity after formatting.

“Usable capacity after formatting” refers to the amount of storage space that is available for use after the SSD has been formatted and any necessary system files have been installed. This value is typically lower than the stated capacity of the drive due to formatting overhead and reserved space for system functions.

When using the CrystalDiskMark test preset +Mix and NVMe random mode, the AGI AI818 1TB NVMe PCIe 4.0 SSD achieved impressive performance results, including a sequential read speed of 5027.85 MB/s and a write speed of 4465.48 MB/s. Additionally, the random RND4K Q32T16 read speed was measured at 2647.63 MB/s, while the write speed reached 3447.88 MB/s.


The ATTO Disk Benchmark utilizes various I/O sizes to test a device’s maximum performance. In the case of the AGI AI818 1TB NVMe PCIe 4.0 SSD, it was tested on the 8th layer of the Direct I/O queue, where it demonstrated a maximum read speed of 4.75 GB/s and a maximum write speed of 4.15 GB/s.

Using the ezIOmeter test tool and running the 1 Thread 128KB QD32 test, the AGI AI818 1TB NVMe PCIe 4.0 SSD achieved a sequential read Mean of 4828.56 Mbps and a sequential write Mean of 6240.47 Mbps. Additionally, its 4K random read and write QD32 performance exceeded 600,000 and 400,000 IOps, respectively.


The PCMark 10 storage test function, Full System Drive Benchmark, evaluates a drive’s performance in 23 typical daily storage tasks, including simulating startup, Adobe program startup, office software operation, and file copying. The results are displayed using a total score and also include details such as average bandwidth and access time.

The AGI AI818 1TB NVMe PCIe 4.0 SSD achieved a score of 2833 points in this test, with an average bandwidth of 451.67 MB/s and an average access time of only 59µs.
