The 512 GB variant offers sequential transfer rates of up to 7000 MB/s reads with up to 3000 MB/s writes, and random-access throughput of 200k/500k (read/write) IOPS. The 1 TB variant, on the other hand, does up to 7400 MB/s sequential reads, up to 5800 MB/s sequential writes, and 400k/750k IOPS.
Endurance of the drives is rated at 250 TBW for the 512 GB variant, and 500 TBW for the 1 TB variant. The 512 GB variant is expected to be priced at 99€, and the 1 TB variant at 179€.”
