which brand is called "Nvme"? [Oct '20 FpsMakerProI9]

MORE DETAILS

While being priced similarly and performs similarly to competitor SSD. This PCI-E 4.0 SSD is priced little bit lower than other PCI-E 4.0 SSDs. Offering one of the fastest R/W speeds, this SSD pretty much guarantee having to wait only few seconds to transfer most (if not the entire) of your photos, videos, documents or game libraries. Random 4K R/W is slightly lower when compared with Intel 900p/905p but worth it for very fast and new PCI-E 4.0 interface and obviously 1TB of storage. Suggested to pay 10 USD extra for heatsink though. [Oct '19 ColdSpy]
