fanxiang 4TB SSD PCIe 4.0 x4 NVMe M.2

The fanxiang S790R 4TB is a PCIe 4.0 NVMe SSD with a PS5-ready heatsink, RGB lighting, and 7350 MB/s read speeds. It's a solid pick for gamers and console owners who want 4TB in one slot without paying flagship prices. Random performance is average and it's DRAM-less, so heavy workstation users should look elsewhere.

Sequential speeds are the headline here. 7350 MB/s read and 6250 MB/s write put this drive in the 86th percentile for speed, which translates to one of the faster PCIe 4.0 drives on the market. In practice, that means game loads, large file transfers, and video scrubbing all feel snappy. The dynamic SLC cache and HMB buffer help maintain those speeds during bursts, but this is still a DRAM-less design, so sustained writes can dip once the cache fills.

Random performance is more middle of the pack at the 62nd percentile. That's fine for gaming and everyday use, but if you're hammering the drive with database workloads or heavy multitasking, you'll notice it's not a top-tier performer. The endurance rating lands at the 57th percentile, which is about average for a TLC drive in this class. The 1.2mm aluminum heatsink and adaptive thermal control should keep throttling at bay, which matters if you're running it in a PS5 or a tight laptop bay.

The Samsung 9100 PRO is the obvious elephant in the room. It's faster, has DRAM, and carries Samsung's reputation, but you'll pay a premium for it. The WD_BLACK WDS800T2XHE is another strong competitor with better endurance and random performance, though it's also pricier. The Kingston FURY Renegade SFYRDK/4000G is probably the closest rival in terms of speed and capacity, and it has a better track record for sustained writes thanks to its DRAM cache.

The Crucial T500 and Micron T710 are both solid alternatives if you want better random performance and don't mind giving up the RGB heatsink. The fanxiang's main edge is that it bundles a heatsink and hits 4TB at a price that undercuts Samsung and WD. But with only 6 reviews and a 24th percentile social proof score, you're taking a bit of a leap of faith on a brand that's still building its reputation in the enthusiast space.

At around $600 USD, the fanxiang S790R 4TB is not a bargain. The affordability percentile of 13th means it's priced near the top of the market. But you're paying for capacity and a heatsink, not raw speed. If you need 4TB in a single M.2 slot and want PS5 compatibility out of the box, this is a reasonable option. If you can live with 2TB, the Crucial T500 or Kingston FURY Renegade will give you better random performance and stronger brand backing for less money. The value proposition here is really about the 4TB capacity in one stick.

The fanxiang S790R 4TB is a PCIe 4.0 NVMe SSD aimed at PS5 owners, gamers, and anyone who wants a big slab of fast storage without paying Samsung or WD prices. It's a DRAM-less drive with TLC NAND, a chunky RGB heatsink, and rated speeds of 7350 MB/s read and 6250 MB/s write. The 4TB capacity puts it in the 93rd percentile for storage space, which is the main reason you'd look at this thing in the first place.

Pricing is all over the map depending on where you live. We're seeing it around $600 USD, 660-673 EUR, and 895 CAD. That's not cheap in absolute terms, but for a 4TB drive with a heatsink and PS5 compatibility, it's positioned as a value play against the usual suspects. The affordability percentile sits at 13th, which tells us this is not a budget drive by any stretch, but the capacity-to-price ratio is where fanxiang is trying to win.

Is the fanxiang S790R good for PS5? Yes, on paper it checks the boxes. It's a 2280 M.2 drive with a pre-installed heatsink, meets the PS5's speed requirements, and supports AES-256 encryption plus TRIM and S.M.A.R.T. The RGB lighting is a nice touch if your motherboard software supports it, though it's wasted inside a PS5 since the console won't light it up.

Skip the fanxiang S790R if you do heavy sustained writes, video editing with large file transfers, or database work. The DRAM-less design and average random performance will frustrate you. If you want a drive with stronger brand recognition and better endurance, the WD_BLACK WDS800T2XHE or Kingston FURY Renegade are safer bets. And if you don't need 4TB, you can get faster 2TB drives for less money.

Should you buy the fanxiang S790R 4TB? If you need 4TB of PCIe 4.0 storage in a single drive and want a PS5-ready heatsink without paying Samsung or WD prices, it's a solid choice. The sequential speeds are genuinely fast, the capacity is huge, and the warranty is decent. But the DRAM-less design and average random performance mean it's not the best pick for heavy workstation use.

For pure gaming and console storage, this drive does the job. For anything more demanding, you're better off with a DRAM-equipped competitor like the Kingston FURY Renegade or WD_BLACK. The fanxiang S790R is a good drive, not a great one, and the lack of customer reviews means you're trusting the spec sheet more than real-world feedback.
