 These SSDs have read speeds of up to 5.0 GB/s and write speeds of up to 4.4 GB/s.Due to their high speed operation, these SSDs use large heatsinks, and if they do not receive sufficient cooling airflow will typically thermally throttle down after roughly 15 minutes of continuous operation at full speed.Samsung also introduced SSDs capable of 8 GB/s sequential read and write speeds and 1.5 million IOPS, capable of moving data from damaged chips to undamaged chips, to allow the SSD to continue working normally, albeit at a lower capacity.
