XPG Mars 980 Blade

Insane Gen5 speed for the money, but boot detection gremlins on some boards keep it from being a no-brainer. Buy it for the speed, keep the receipt for the headaches.

The numbers here are genuinely wild. Sequential reads hit 14,000 MB/s and writes land at 12,000 MB/s, which is best-in-class territory. Random performance is just as strong at 2,000K read IOPS and 1,650K write IOPS, so this thing shreds through everything from game loads to 8K video scrubbing. The SMI SM2508 controller paired with DRAM cache keeps sustained writes from falling off a cliff too. What surprised us most is that a drive this fast doesn't cost a fortune. But those boot detection complaints on Gigabyte and AMD boards are a real buzzkill, and one owner said benchmark scores felt more like PCIe 4.0 territory in some scenarios.

The Samsung 990 PRO is the obvious rival, and it's still the safer bet if you want zero drama. It's a Gen4 drive, so it tops out around 7,450 MB/s, but it's bulletproof and widely compatible. The Crucial T500 is another Gen4 option that trades blows with the 990 PRO and often costs less. If you want Gen5 speed without the XPG's boot quirks, the WD_BLACK SN8100 is worth a look, though it typically costs more. The Kingston Fury Renegade is a solid Gen4 fallback if you just want reliable speed without the Gen5 tax.

At USD 180 to USD 200 across US listings, this drive undercuts the Samsung 9100 by a meaningful margin while delivering similar headline speeds. The best deal we're seeing is at the low end of that USD 20 spread, so shop around before you pull the trigger. For Gen5 performance, this is aggressive pricing. The value story gets murkier if you end up fighting boot detection issues, but on paper and in most real-world use, you're getting flagship speed for mid-range money.

The XPG Mars 980 Blade is one of the fastest Gen5 drives you can buy right now, and it does it without the usual early-adopter tax. We're talking 14,000 MB/s reads and 12,000 MB/s writes, which puts it in the top tier of our database. But there's a catch: some owners are reporting boot detection issues on certain motherboards, and that's not the kind of problem you want from your boot drive.

If you're building a system where stability matters more than raw speed, this isn't your drive. The boot detection issues on some boards are a real concern, and the last thing you want is a drive that plays hide and seek with your BIOS. Go grab a Samsung 990 PRO or Crucial T500 instead. They're Gen4, so you'll leave some speed on the table, but they just work. And if you're on a tight budget and don't need Gen5, the Kingston Fury Renegade is a solid pick that won't keep you up at night.

If you want Gen5 speed and you're willing to roll the dice on compatibility, the Mars 980 Blade is a screaming deal. The raw performance is undeniable, and the price makes it tempting. But if this is going to be your boot drive, the detection issues reported on some boards give us pause. Test it immediately, update your BIOS, and if it misbehaves, return it fast. For most people, the Samsung 990 PRO remains the safer recommendation, but the XPG is the value play for speed junkies.
