At the risk of speaking too soon, the Great Memory Price Spike of 2026 just might be over. At least that’s what we’re getting from this new Amazon deal that is dropping the price of Samsung’s 990 PRO PCIe 4.0 internal solid-state hard drive by 39%. The 2TB model has gone from $640 to just $390. This is Samsung’s flagship PCIe 4.0 drive, and it seems like it’s been ages since we’ve had a deal this good on it.
The 990 PRO delivers sequential read speeds of 7,450 MB/s and sequential writes of 6,900 MB/s, which is about as close to the theoretical ceiling of the PCIe 4.0 interface as any drive gets. That means large file transfers finish in seconds, game assets stream fast enough that load screens become a background event, and demanding workloads like 4K video editing or data analysis stop bottlenecking on storage. Samsung rates the 2TB model at 1,200 TBW endurance and backs it with a five-year limited warranty, which is the kind of confidence you want from a primary system drive.
Random Read Turbo Boost
The improvement in random performance is what you actually feel during everyday use, and that is where the 990 PRO makes its case most clearly. Samsung cites more than 55% better random read performance over the previous 980 PRO, which shows up in system boot times, application launches, and multitasking under load. For gaming specifically, it translates to faster level loads and smoother asset streaming in open-world titles that pull data off the drive continuously rather than in bursts.
The 2TB model hits a sweet spot. It’s enough room for a sizable game library alongside a working project folder or a heavy application suite, without the constant file management that 1TB forces on you. The drive scales up to 4TB if your workload justifies it, but 2TB is where most high-end builds land, and it is where this deal lives. The M.2 2280 form factor is standard, so it drops into most modern motherboards and laptops without an adapter.
Cooler Heads Prevail
Power efficiency is also a factor here. The 990 PRO delivers up to 50% better performance per watt than the 980 PRO it replaced. Less power draw means less heat, which means less thermal throttling during sustained workloads, which matters most for compact builds or laptops where thermal headroom is limited and throttling can pull sequential speeds down considerably under load.
The $640 Amazon list price on the 990 PRO is on the high end for this generation of PCIe 4.0 storage, but the current $390 sale price may be a sign of things to come. If you are building a high-end gaming rig or a workstation that needs fast, reliable primary storage and you have been watching prices climb on flash memory, the current deal at Amazon is worth moving on.
