The drive is capable of reaching up to 7,400 / 6,600 MB/s for sequential reads. AGI does not list the random read and write IOPS specifications, but we know this controller and flash combination tends to reach at least 700K and can reach 1,000K or more. This is comparable to other drives in this class. We wouldn’t recommend the drive at 512GB as it can’t reach peak performance. Ideally, you would go for 2TB or 4TB for the best results. The drive is backed by a five-year, 740TB of data writes per TB of capacity warranty, which is above average but not exceptional.
AGI offers no downloads aside from the spec sheet. For checking drive health information, we recommend CrystalDiskInfo . CrystalDiskMark , its sibling, is good for benchmarking your drive to make sure everything is working well. For backups and disk imaging/cloning, we recommend MultiDrive for Windows and either Clonezilla or Rescuezilla for other operating systems or for booting.

Considering it’s a high-end PCIe 5.0 drive, that’s fine – you’ll be using this in an enthusiast desktop, most likely.
There’s not too much else interesting here unless you read the PCB silkscreen lettering beneath the rear label. This gives you information after the drive and its components – it’s using the Silicon Motion SM2508 (SM2508) controller in the M.2 (M2) form factor with LPDDR4 (LPD4) volatile memory, four NAND flash packages (4) in the BGA178 (178) form factor with an SMI reference design (Y260A), manufactured during week 23 of 2025 (25.23). This information could be useful to you in multiple scenarios: when you’re looking at review photos of drives, when you are checking a drive you purchased, or when you’re comparing drives.

The Samsung memory is low-power, which is good, and is in a 16Gb or 2GB configuration, which means the drive meets the usual 1GB:1TB DRAM:NAND ratio.
