When it comes to the subject of SSDs, you always hear a wide variety of opinions. With or without DRAM? The SLC cache must be large and, above all, an SSD must be able to do everything. From simple office to gaming to total servitude in the workstation sector. The latter in particular places extreme demands on the SSD and this is then reflected in the price. But do you really need such an expensive SSD?
Kingston advertises the Kingston NV3 as a price-performance SSD. The question remains: How well can a PCIe 4.0 SSD with QLC memory – without DRAM – really deliver? Kingston provided me with a 2 TB NV3 for this test. I have summarized the technical data in a table so that you can draw any conclusions about the other variants from today’s test.

Before I really stress the NV3, let’s take a quick look at the circuit board. Please understand that I can’t take the high-resolution pictures and analyses that you’re used to from Igor. For today’s test, however, this will suffice, because in the end it’s the performance that counts and it doesn’t matter what was soldered onto the board.
A note in advance:
Kingston is playing with open cards here and has pointed out to me that they have deliberately calculated with a mixed BOM (Bill of Materials) for the NV3. This means that they are keeping an open mind as to who the components will ultimately come from. Be it memory or the controller, this is to counteract possible supply bottlenecks. I really appreciate this openness on Kingston’s part. I have also been assured that the specified values (read/write) are always adhered to. Of course, I can’t test this here and now, as I only have this one model.
