Patriot VIPER PV593

The Patriot Viper PV593 is a 4TB PCIe 5.0 NVMe SSD with elite sequential and random performance, backed by a 4GB DRAM cache and 3,000 TBW endurance. It's one of the fastest drives in our database, but it ships without a heatsink and carries a shorter 3-year warranty. Buy it for workstation use or if you want maximum Gen5 speed, but gamers can save money with a good Gen4 alternative.

The PV593 is fast. Really fast. Sequential reads hit 14,000 MB/s and writes land at 12,000 MB/s, which puts it in the 96th percentile for speed in our database. That's best-in-class territory for Gen5 drives. Random performance is even more impressive, with 2,000K read IOPS and 1,650K write IOPS landing at the 97th percentile. For anyone moving huge video files, running VMs, or just wanting Windows to feel instant, this drive delivers.

In practice, those numbers mean game load times shrink to near nothing and large file transfers finish before you can grab a coffee. The 4GB DDR4 DRAM cache helps keep sustained writes consistent, which is something cheaper DRAM-less drives struggle with. The SM2508 controller is also known for running cooler than some earlier Gen5 controllers, though you'll still want some airflow over the bare M.2 stick.

Against the Samsung 9100 PRO, the PV593 trades blows on sequential reads but falls slightly behind on brand trust and warranty length. Samsung's drive also tends to run cooler and has a much larger review base. The WD Black SN850X and SanDisk Black SN850X are Gen4 drives, so they top out around 7,300 MB/s, but they're often significantly cheaper and still feel fast in everyday use. The Seagate FireCuda 530R and Kingston Fury Renegade are also Gen4 options with strong reputations and longer warranties.

If you're building a new system with a Gen5-capable motherboard and want the fastest storage possible, the PV593 makes a strong case. But if you're upgrading an older system or just want a big, fast game library, the Gen4 alternatives will save you money without a noticeable drop in real-world performance. The PV593's random performance is genuinely elite though, so heavy multitaskers and content creators will notice the difference more than gamers.

At CAD 900, the PV593 sits in a weird spot. It's cheaper than the Samsung 9100 PRO at 4TB, but pricier than last-gen Gen4 drives like the WD Black SN850X or Kingston Fury Renegade that still offer excellent real-world performance. If you need Gen5 speed and 4TB of space, the value is there. But if you're mostly gaming, a good Gen4 drive will feel nearly identical in day-to-day use and save you a chunk of change. The 3,000 TBW endurance rating is solid for the capacity, though the 3-year warranty is a bit stingy compared to the 5-year coverage Samsung and WD typically offer.

The Patriot Viper PV593 is a 4TB PCIe 5.0 NVMe SSD aimed at people who want top-tier sequential throughput without paying flagship Samsung money. It sits in that upper mid-range Gen5 bracket, with a 4GB DRAM cache, TLC NAND, and the Silicon Motion SM2508 controller doing the heavy lifting. At around CAD 900 in the one listing we track, it's not cheap, but it's also not the most expensive 4TB Gen5 drive out there.

If you're searching for a high-capacity internal SSD for a workstation or gaming rig, this one checks a lot of boxes. You get 14,000 MB/s reads and 12,000 MB/s writes on paper, plus 2,000K random read IOPS. That puts it near the top of our database for raw speed. The catch is that it ships without a heatsink, so you'll want to make sure your motherboard has one built in or grab an aftermarket cooler.

We've seen a 4 out of 5 customer rating on this drive, which is decent but not glowing. The social proof percentile is low, mainly because there just aren't that many reviews out there yet. That's not a knock on the drive itself, but it does mean you're buying on specs and trust in Patriot rather than a mountain of user feedback.

Skip the PV593 if you're building a portable setup or need a drive for a laptop with tight thermal constraints. Its portable score of 23.2 out of 100 is the weakest area in our testing, and the lack of a heatsink makes it a poor fit for cramped enclosures. Gamers on a budget should also look elsewhere, since a Gen4 drive like the Kingston Fury Renegade or WD Black SN850X will deliver nearly identical real-world performance for less money. And if you want a drive with a long track record and tons of user reviews, the Samsung 9100 PRO is the safer bet.

Should you buy the Patriot Viper PV593? If you want a 4TB Gen5 SSD with top-tier random performance and you're okay with the CAD 900 price tag, yes. It's one of the fastest drives we've tested in its class, and the 4GB DRAM cache plus 3,000 TBW endurance make it a solid long-term investment for a workstation.

But if you're mainly gaming or just need more storage without chasing benchmark numbers, a Gen4 drive like the WD Black SN850X will serve you just as well for less money. The PV593 is a performance enthusiast's drive, and it delivers on that promise. Just budget for a heatsink if your motherboard doesn't have one.
