The low price tag on this ssd had me interested - but after reading some online reviews I'm definitely re-thinking on this. It sounds like many people had been running into issues of the SSD going dead after a few months of use - and that probably explains the low price to begin with. I would definitely not trust putting any irreplaceable data on it.

Best SSD on the market, will boom soon!

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.

Note that you get PCIe 3 speed with a AMD Ryzen 2 processor. To get the PCIe 4 speed you will need a AMD Ryzen 3 processor.
