Another lightning quick PCIe 4.0 SSD emerges, now let’s see prices come down



Teamgroup becomes the latest storage maker to roll out an ultra high-speed PCIe 4.0 solid state drive line, the T-Force Cardea A440. The appeal of PCIe 4.0 SSDs is they leverage advanced controller hardware and speedy NAND flash memory chips to nearly saturate the PCIe 4.0 x4 bus. They also carry a heavy pricing premium over PCIe 3.0 models, though at least the A440 comes two heatsinks for a bit of added value (more on that in a moment).

As to the rated performance, Teamgroup says its A440 SSDs deliver up to 7,000MB/s of sequential reads and up to 6,900MB/s of sequential writes. There are competing SSDs rated to push read operations even higher than what the A440 purportedly offers, but the claimed write speed of the A440 is tops. Here’s a look at how it slots in among the competition:
