Spending $200 or more on a single drive might seem to be a daft thing to do when there are some great to be found. But these two offers are a bit special because you're looking at 4 TB of NVMe storage, for a price that's as low as $0.05 per GB. Yes, that's right—just five cents per gigabyte. The mind boggles.

• We're curating all the right here.

What I've got here is a nice choice of big-but-not-super-fast and big-and-super-fast, and there's only a $21 difference between the two. So just go for the latter, yes? Well, it's not quite as simple as that.

Prime Day 4 TB SSDs

The cheaper offer is for a Silicon Power UD90 SSD. It's hard to tell exactly what NAND flash and controller chip is used in this model because Silicon Power uses a variety of suppliers for its parts. No matter what's underneath the label, though, it's not the fastest PCIe 4.0 SSD you'll see and the lack of DRAM means it won't be able to sustain its performance when handling hundreds of GBs of files.

But for general storage, be it a backup, documents, or games, it will be fine and it will serve you well for many years. Just make sure that you fit [[link]] it into a motherboard that has heatsinks on its M.2 slots to prevent the drive from getting too hot.

Silicon Power does have a full-speed 4 TB SSD and it's the larger version of the . It's ridiculously fast and stable, thanks to the chunky pre-installed heatsink, though it doesn't offer hardware encryption. It's also suitable for use in a PlayStation 5, should you want to max out the storage on one of those.

For gaming PCs, it's a near-perfect storage solution. It uses Micron's TLC flash memory chips and a Phison controller, so performance won't be an issue. You can use it as an expansion drive, just to store games, but it's perfectly fine in the role of a sole SSD, hosting the operating system, applications, and games.

That big heatsink is quite easy to remove, so you can install it in motherboards that come with M.2 slot heatsinks. Personally, I quite like how it looks with its cooler, as it's quite understated in design.

Out of the [[link]] two Silicon Power SSDs, I'd go with the XS70—for just $21 more, you're getting much better performance and probably better longevity, though it takes some serious amount of data writing and erasing to ruin a modern SSD in a short space of time.

It wasn't that long ago when SSDs were considered big at 1 TB. Now you can get one four times that size, big enough to store over 25 copies of Baldur's Gate 3. That's progress for you.
