Pictured below you can see the OEM version of the 980 SSD, which sports impressive performance:
The performance, according to the seller's listing, looks very good. The 1TB model delivers up to 3,200 MB/s sequential read and 2,400 MB/s sequential write performance. Random 4KB numbers run up to 380,000 IOPS read and 440,000 IOPS write. We've already seen a CrystalDiskMark result with even higher performance but have yet to verify the legitimacy of the image.
