XPG GAMMIX S70 Blade 1TB PCIe 4.0 x4 NVMe M.2 2280

The XPG GAMMIX S70 Blade is a 1TB PCIe 4.0 NVMe SSD with 7400 MB/s reads, excellent random performance, and a 740 TBW endurance rating. It's a great value at the lower end of its price range and works perfectly as a PS5 expansion drive thanks to the included heatsink. Just don't try to remove that heatsink, it's not meant to come off.

The headline numbers are 7400 MB/s sequential read and 5500 MB/s sequential write. In practice, that means a 100GB game install copies over in roughly 18 seconds if the source drive can keep up. Random performance is where this drive really shines though. 740K random read IOPS and 740K random write IOPS put it in the 90th percentile for random workloads, which translates to snappy boot times, fast level loads, and responsive application launches. It's not just a benchmark queen, it feels fast in daily use.

Our database shows the speed lands in the 82nd percentile overall, which is strong but not chart-topping. Drives like the Samsung 990 PRO and Crucial T700 will edge it out in certain synthetic tests, especially sustained writes. But for real-world gaming and general productivity, the S70 Blade is close enough that most people won't notice the difference. The DRAM cache helps keep things consistent under load, and the heatsink does its job keeping thermals in check during long transfers.

The Samsung 990 PRO is the elephant in the room. It's faster in sustained writes and has a more polished software ecosystem, but it typically costs more and doesn't include a heatsink on the base model. The Crucial T700 is a PCIe 5.0 drive that absolutely demolishes this thing in sequential benchmarks, but you need a compatible motherboard and it runs hot. For most people on PCIe 4.0, the S70 Blade is the more practical choice.

The Kingston Fury Renegade is probably the closest direct competitor. Similar speeds, similar endurance, similar price bracket. The Kingston drive has a slightly better reputation for firmware stability, but the XPG drive's included heatsink gives it an edge for PS5 users. The Team Group MP44 undercuts the S70 Blade on price but gives up some random performance and endurance. If you're building a gaming PC and want to save a few bucks, the MP44 is worth a look. If you want the heatsink and the higher TBW rating, the S70 Blade justifies its premium.

Pricing on this drive is all over the place. We're seeing USD 190 to USD 274 across two US listings, which is a spread of USD 84 for the exact same product. That's wild. If you're shopping, the lower end of that range is a genuinely good deal for a drive with this feature set. At USD 190, you're getting 99th percentile features and 92nd percentile endurance for budget drive money. At USD 274, you're creeping into territory where the Samsung 990 PRO and other premium options start looking more attractive. The CAD 377 listing in Canada is harder to judge without local context, but it's worth comparing against local alternatives. Shop around before you pull the trigger, because the same drive can cost dramatically different amounts depending on where you click.

The XPG GAMMIX S70 Blade is a 1TB PCIe 4.0 NVMe SSD that sits in that sweet spot between budget drives and flagship screamers. It's marketed as a do-everything drive for gaming, content creation, and even PS5 expansion, and the spec sheet backs that up. You get 7400 MB/s sequential reads, 5500 MB/s writes, TLC NAND, a DRAM cache, and a pre-installed heatsink. The Innogrit IG5236A1 controller is a known quantity at this point, and it's a solid pairing for this class of drive.

People searching for a fast 1TB NVMe SSD for gaming or a PS5-compatible drive will find this one popping up a lot. It's not the cheapest option out there, but it's not trying to be. The feature set lands in the 99th percentile for this category, which means you're getting hardware encryption, a heatsink, and a 5-year warranty all in one package. That's a lot of box-ticking for a drive that often sells in the mid-$200 range.

We've seen this drive used as a boot drive, a game library, and a scratch disk for video editing. It handles all of those without breaking a sweat. The 740 TBW endurance rating is well above average for a 1TB drive, so you won't be burning through write cycles anytime soon.

If you're running a motherboard with a built-in M.2 heatsink and you want to use it, skip this drive. The pre-installed heatsink is not designed to be removed, and trying to pry it off can destroy the drive. If you're on a tight budget, the Team Group MP44 offers similar real-world performance for less money, though you'll give up some endurance and the included heatsink. And if you're building a PCIe 5.0 system and want maximum sequential throughput, the Crucial T700 is the obvious choice, assuming your board supports it and you can handle the thermals.

The XPG GAMMIX S70 Blade is a genuinely fast, well-equipped PCIe 4.0 SSD that delivers on its promises. The 7400 MB/s reads are real, the random performance is excellent, and the 740 TBW endurance rating means you won't have to think about wearing it out. For PS5 owners, the included heatsink makes this a plug-and-play expansion option that just works. For PC builders, it's a strong choice for a boot drive or game library.

Should you buy it? If you can find it at the lower end of that USD 190 to USD 274 range, absolutely. It's a lot of drive for the money. If it's sitting at the top of that range, you should seriously consider the Samsung 990 PRO or Kingston Fury Renegade instead. The one real caveat is the heatsink. If you have a motherboard with its own M.2 heatsink and you're planning to remove the pre-installed one, don't. It's not designed to come off, and forcing it can destroy the drive. Buy the bare version if you can find it, or just use the included heatsink and call it a day.
