light speed ssd [Feb '21 tester4678]

MORE DETAILS

The entry level NVMe PCIe 4.0 SSD as this PCIe 4.0 SSD comes cheaper than any other PCIe 4.0 SSD in the market but you'll get half the capacity of regular Sabrent Rocket 4.0 1TB and performs a little slower than the mentioned SSD. This SSD appeals to niche market as use case for this PCIe 4.0 SSD is limited outside of application requiring high sequential R/W and 4K R/W so consumers (or prosumers, in storage hungry cases) may be looking for higher capacity SSD at same price instead. [Dec '19 ColdSpy]
