How much storage space do you need for your game library? So, thanks to the Amazon Prime Day SSD sale, here's a 4TB SSD for only $159, the TeamGroup MP34 4TB, at only 4 cents per GB. Amazing.

And this is no ordinary SSD. While certainly not the ultimate in cutting-edge solid state storage, this is a proper M.2 NVMe drive with TLC NAND memory, not a cheap horror product with QLC memory that drops off a performance cliff when it runs out of SLC cache. It also has a Phison controller and DRAM cache, but the amount is unknown.

But the point is that a proper SSD - one that you want to use as your main boot drive, not bulk storage - absolutely needs both TLC memory and DRAM, not QLC. And this drive delivers both. [It is a very old model with a quad-lane PCIe Gen 3 interface and Phison's much older E12 controller chip. As a result, peak throughput is relatively modest at 3.5GB/s read and 2.9GB/s write.

However, IOPS performance is there, around 450,000 times, and it has a 5-year warranty and 2,400TB write endurance.

So here's the thing. In most cases, you won't feel the difference between this drive and the latest 12GB/s PCIe Gen 5 monster that costs three times as much. Compared to any SATA SSD, this is a quantum leap. And it completely destroys older HDDs.

We have not reviewed this particular TeamGroup SSD, but according to the Reddit hivemind, it is a decent drive from a reliability standpoint.

To put this in perspective, the 4TB version of our favorite current SSD, the WD SN850X, is currently on sale at Prime for $229.99. If you're not so price-sensitive, this might be a safer bet. And for such a large version of such a great drive, it's a real bargain.

But honestly, there is no question about pulling the $159 trigger on this TeamGroup drive. It has adequate specs and comes with a five-year warranty.
