ADATA SSD

The ADATA GAMMIX S70 Blade is a 2TB PCIe 4.0 NVMe SSD that delivers near-flagship speeds at a mid-range price. It's a great pick for gaming, PS5 storage expansion, and general use, with a removable heatsink and solid endurance. Just shop around, since US prices vary by over $30 between vendors.

The S70 Blade is quick. Sequential reads hit 7400 MB/s and writes land at 6800 MB/s, which means big file transfers and game loads happen in a blink. Random performance is also strong at 750K IOPS for both read and write, putting it in the 86th percentile for random operations in our database. In practice, that translates to snappy boot times, fast level loads, and smooth scrubbing through large video files.

It uses TLC NAND with a DRAM cache and SLC caching tech, which helps keep those write speeds consistent even when you're moving a lot of data at once. The 1480 TBW endurance rating is solid for a 2TB drive, though not class-leading. For most people, that's years of heavy use before you'd even think about wearing it out. The included aluminum heatsink does its job, keeping temps in check during sustained transfers, and you can remove it if your motherboard or PS5 already has its own cooling solution.

The Samsung 990 Pro is the elephant in the room. It's faster in some workloads and has a stronger brand reputation, but it also costs more. The S70 Blade gets you within spitting distance of that performance for less cash, which is the whole pitch. The Western Digital Black SN850X is another close competitor, with similar speeds and a slightly better track record for reliability. The Seagate FireCuda 530R and Kingston KC3000 are also in the mix, but the S70 Blade tends to undercut them on price while matching or beating them on raw throughput.

Where the S70 Blade gives up ground is in the details. The Samsung and WD drives have more refined software, better warranty support, and slightly more consistent performance under heavy sustained loads. But if you're just gaming, editing video, or expanding your PS5 storage, those differences are hard to feel. The S70 Blade is the value play in this group, and it's a good one.

Pricing on this drive is a bit of a moving target. US listings range from $317 to $350, so it pays to shop around. Newegg and Amazon both carry it, and the spread between vendors is wide enough that you could save over $30 just by checking both before you buy. At the lower end of that range, the S70 Blade is a genuinely good deal for a 2TB Gen4 drive with this level of performance. At the higher end, it starts to bump up against drives like the WD Black SN850X, which sometimes goes on sale for similar money. For Canadian buyers, it's listed at CAD 480, which is competitive but not a steal. If you're patient and catch it at the right price, this drive delivers a lot of speed per dollar.

The ADATA GAMMIX S70 Blade is a 2TB PCIe 4.0 NVMe SSD that sits in that sweet spot where high-end performance meets a price that doesn't make you wince. It's aimed at gamers, creators, and anyone who wants a fast boot drive or a roomy game library without paying Samsung 990 Pro money. With a heatsink included and PS5 compatibility baked in, it's one of those drives that just works in a lot of different setups.

People searching for a fast 2TB SSD for gaming or a PS5 storage upgrade will find a lot to like here. The drive is rated for up to 7400 MB/s read and 6800 MB/s write, which puts it near the top of the PCIe 4.0 food chain. It's also backward compatible, so it'll drop into older PCIe 3.0 laptops and desktops without drama, just at lower speeds.

Our database shows this drive ranking in the 93rd percentile for features and 90th percentile for speed among all internal SSDs we track. That's the kind of placement that makes you sit up and pay attention. It's not the absolute fastest Gen4 drive on the market, but it's close enough that most people won't notice the difference outside of benchmark screenshots.

If you need a portable SSD, this isn't it. The S70 Blade is an internal M.2 drive, and our database scores it at just 26.5 out of 100 for portable use. It's also not the pick if you want the absolute fastest Gen4 drive or the best warranty support. Samsung 990 Pro buyers who value brand reputation and software polish should stick with Samsung. And if you're the type who never wants to deal with an RMA, WD's SN850X has a better support track record. For everyone else, especially budget-conscious gamers and PS5 owners, this drive is a strong buy.

Should you buy the ADATA GAMMIX S70 Blade? If you want a fast 2TB Gen4 SSD and don't want to pay Samsung prices, yes. It's fast, easy to install, and works in everything from gaming PCs to PS5s to laptops. The included heatsink is a nice touch, and the performance is close enough to the top dogs that most people won't care about the gap.

That said, it's not perfect. The portable use case is weak, and there's at least one report of an early failure with a frustrating RMA experience. ADATA's warranty support doesn't have the same reputation as Samsung or WD. But with a 4.6-star rating across over 12,000 reviews, most buyers are happy. For the money, this is one of the best Gen4 SSD deals you can find right now.
