PNY CS2140 PCIe Gen 4×4 NVMe SSD Review – Both the 500GB and 1TB Models are Using Phison E19T Controller

Overall, the PNY CS2140 series of PCIe Gen 4×4 NVMe SSDs are pretty decent. They are indeed DRAMless to cut cost – and that is the most important point to take note of – the price.The SSDs themselves do not have any heatsinks or heatspreader stickers. If we peel it back a little, we can see that the SSD controller used on both the 500GB and 1TB models are using Phison E19T controller. This controller supports TLC NAND chips but DRAMless cache.
