NVMe (PCIe Gen4 x4) technology with up to 5000MB/s sequential reads, random read/write 650K/800K IOPS. Spacious storage up to 4TB. Performs up to 43% faster than the fastest Gen3 NVMe SSDs. Rated at MTTF greater than 1.5 million hours for extended longevity and reliability. Backward compatibility with Gen3. Capacity – 500GB Sequential Read – 4700 MB/s Sequential Write – 1900 MB/s SSD Endurance (TBW) – 110 Terabytes Capacity – 1 TB Sequential Read – 5000 MB/s Sequential Write – 3600 MB/s SSD Endurance (TBW) – 220 Terabytes Capacity – 2 TB Sequential Read – 5000 MB/s Sequential Write – 4200 MB/s SSD Endurance (TBW) – 440 Terabytes. Typical I/O performance numbers as measured using CrystalDiskMark with command queue full and write cache enabled. Fresh out-of-box (FOB) state is assumed. For performance measurement purposes, the SSD may be restored to FOB state using the secure erase command. System variations will affect measured results. Some of the storage capacity is used for formatting and other purposes and is not available for data storage. 1GB equals 1 billion bytes. Not all capacities available at initial launch.
