Silicon Power XS70 2TB PCIe 4.0 NVMe M.2 2280

The XS70 hits 7,300 MB/s read and 6,800 MB/s write, landing in the 91st percentile for speed. It's backed by a 1,400 TBW endurance rating and a 5-year warranty. The built-in heatsink makes it a great PS5 upgrade, though the USD 570 price means it's not for budget builds.

The headline numbers are 7,300 MB/s sequential read and 6,800 MB/s sequential write. That's top of the charts for PCIe 4.0 drives, and it translates to faster game loads, quicker file transfers, and snappier overall system response. The DRAM cache helps here, especially with random reads and writes, which sit at the 81st percentile. Not the absolute best for random workloads, but still well above average.

For a workstation, this drive scores 84.1 out of 100 in our testing. That's a strong showing, driven by the sequential speed and endurance combo. The console score is 82.6, which makes sense given the PS5 compatibility and the heatsink. The weak spot is portability at 22 out of 100, but that's expected for an internal M.2 drive with a heatsink. You're not tossing this in a laptop bag.

Against the Western Digital Black SN850X, the XS70 trades blows on sequential speed but gives up some ground on random performance. The Samsung 9100 PRO is a PCIe 5.0 drive, so it's in a different league for raw speed, but it costs significantly more. The Kingston FURY Renegade G5 and Crucial T500 are closer competitors, with the T500 often coming in cheaper while offering similar endurance. The Seagate FireCuda 530R has a comparable heatsink design and endurance rating, but the XS70's 1,400 TBW edges it out on paper. If you're building a PS5, the XS70's built-in heatsink and 82.6 console score make it a solid pick against all of these.

At USD 570 for the 2TB model, the XS70 is not cheap. But you're paying for the endurance rating and the heatsink, not just the speed. The 1,400 TBW rating means this drive will likely outlive your current system. The CAD 923 listing in Canada is a different market, so don't try to compare those numbers directly. For a PS5 upgrade or a workstation that sees heavy writes, the price per terabyte is justified by the longevity. For a casual gaming PC, you could save money with a slower drive and never notice the difference.

The Silicon Power XS70 hits 7,300 MB/s read and 6,800 MB/s write, which puts it in the 91st percentile for speed in our database. That's the kind of number that makes a PS5 or a heavy workstation feel instantly more responsive. The 2TB capacity and DRAM cache mean you're not just getting burst speed, you're getting sustained performance when you're moving big files or loading massive game worlds.

Endurance is another strong point. 1,400 TBW and a 5-year warranty put this drive at the 89th percentile for longevity. The built-in heatsink, with those shark gill slits, is actually functional, not just a gimmick. It keeps thermals in check during long sessions, which matters more than most people think for a drive this fast.

Skip this drive if you're building a thin laptop or a small form factor PC where the heatsink won't fit. The portable score of 22 out of 100 is a real limitation. Also skip it if you're on a budget and just need a boot drive for everyday tasks. The USD 570 price is hard to justify when a mid-range PCIe 4.0 drive without a heatsink will feel nearly identical for web browsing and office work. And if you need the absolute best random performance, the 81st percentile ranking means there are faster options for database or heavy multitasking workloads.

The Silicon Power XS70 is a data-backed winner for anyone who needs a fast, durable PCIe 4.0 drive with a heatsink. The 7,300 MB/s read speed and 1,400 TBW endurance put it near the top of our charts, and the 4.7-star rating from over 2,200 buyers confirms it's not just spec sheet hype. If you're upgrading a PS5 or building a workstation that handles large files regularly, this drive earns its price. If you just need a boot drive for light gaming, you're overspending.
