AGI 1TB SSD PCIe 4.0 x4 NVMe M.2

The AGI AI828 is a 1TB PCIe 4.0 NVMe SSD with impressive 7400 MB/s read speeds and a monster 3000 TBW endurance rating. It includes a heatsink and works great in a PS5, but the DRAM-less design and premium price make it a tough sell against the Samsung 990 PRO or WD_BLACK SN850X. Buy it on sale, not at full price.

The sequential speeds are the star here. 7400 MB/s read and 6700 MB/s write put the AI828 near the top of the PCIe 4.0 charts. In our database, this drive lands in the 92nd percentile for speed, which means it's faster than the vast majority of drives we've tested. Game load times, large file transfers, and video editing scrubbing will all feel snappy. The SLC cache helps with burst writes, so copying a 50GB game folder won't immediately tank performance the way it does on cheaper QLC drives.

But the random performance is more middle of the pack. At the 62nd percentile, it's fine, but not exceptional. That's the DRAM-less design showing through. Everyday tasks like booting Windows, launching apps, and loading game levels rely heavily on random reads, and while the AI828 handles those fine, it doesn't have the same instant responsiveness as a drive with dedicated DRAM. The heatsink does its job though. AGI uses a dual-sided thermal design with fins on top and a heat-spreading back cover, which helps keep temperatures in check during long gaming sessions or sustained writes.

Against the Samsung 990 PRO, the AI828 actually holds its own on sequential reads, 7400 MB/s versus the 990 PRO's 7450 MB/s. But the 990 PRO has DRAM, better random performance, Samsung's Magician software, and a track record that spans millions of units. The Crucial T500 is another strong alternative, often priced lower than the AI828 while offering similar speeds and better all-around performance. The Kingston Fury Renegade and WD_BLACK SN850X are both excellent choices too, with the SN850X being a particularly popular pick for PS5 expansion.

The AI828's one clear advantage is endurance. 3000 TBW dwarfs the 600 TBW rating on the 990 PRO and the 600 TBW on the SN850X. If you're doing heavy write workloads, like constant video recording or running a cache drive, that endurance headroom matters. But for gaming and general use, most people will replace their entire system before they hit even 600 TBW. The Micron T710 is another competitor worth mentioning, though it's less common in consumer retail channels. None of these alternatives include a heatsink at the 1TB capacity as standard, so if you need one for a PS5, factor in that extra cost.

Here's where things get tricky. At $240 USD for 1TB, the AGI AI828 is priced right alongside the Samsung 990 PRO and WD_BLACK SN850X, both of which are established flagships with DRAM caches and years of proven reliability. The AI828 does include a heatsink, which those drives sometimes don't at this capacity, but that's not enough to justify the price gap in brand trust. The endurance rating is a genuine selling point, 3000 TBW is exceptional for a 1TB drive, but most users will never come close to hitting even a third of that. If you can find this drive on sale for meaningfully less than the big names, it becomes a lot more interesting. At full price, you're paying flagship money for a drive with budget-tier internals and a fancy heatsink.

The AGI AI828 is a 1TB M.2 PCIe 4.0 NVMe drive that sits in a weird spot. It's priced like a premium drive in most markets, around $240 USD or 224 EUR, but it comes from a brand most people haven't heard of. AGI is a Taiwanese company, and this drive is aimed squarely at PS5 owners and PC builders who want fast storage without thinking too hard about it. The headline numbers are solid: 7400 MB/s read and 6700 MB/s write, with TLC NAND and a heatsink included.

So is the AGI AI828 good for gaming? On paper, yes. It hits the speed requirements Sony lists for PS5 expansion storage and the included heatsink means you don't need to buy a separate one. But the drive is DRAM-less, which is unusual at this price point. Most drives charging this much include a DRAM cache. Instead, the AI828 relies on HMB, or Host Memory Buffer, which borrows a chunk of your system RAM to handle the mapping tables. That works fine for gaming and everyday use, but it's a corner cut you don't expect to see when the price tag matches a Samsung 990 PRO.

For a 1TB internal SSD, the endurance rating is genuinely impressive. AGI rates it at 3000 TBW, which is triple what most 1TB drives offer. That's the kind of number that makes you wonder if they're being optimistic, but if it holds up, this drive will outlive most of the systems it gets installed in.

Skip the AGI AI828 if you're building a workstation or doing heavy random I/O workloads. The DRAM-less design means database operations, virtualization, and sustained small-file transfers will feel less responsive than on a drive with dedicated DRAM. If you're spending this much money, the Samsung 990 PRO or Crucial T500 are better picks for productivity. Also skip it if you want a drive from a brand with a proven support network. AGI's warranty is standard on paper, but with almost no customer reviews and limited retail presence, getting a replacement could be a headache. For a boot drive in a daily driver PC, we'd rather have the peace of mind that comes with a WD or Samsung drive at the same price.

Should you buy the AGI AI828? If you find it on sale for 20-30% less than the Samsung 990 PRO or WD_BLACK SN850X, sure. The speed is there, the endurance is outstanding, and the included heatsink makes it a drop-in PS5 upgrade. But at full retail price, it's hard to recommend over the established flagships. You're giving up DRAM, brand reputation, and software support without saving any money.

The 4.4-star rating from just 4 reviews doesn't tell us much. That's a tiny sample size, and AGI doesn't have the same retail presence or support infrastructure as Samsung, WD, or Crucial. The 365-day warranty is standard, but the real question is how easy it is to actually get a replacement if something goes wrong. For a drive that costs this much, we'd rather have the peace of mind that comes with a brand we know will still be around in five years.
