CrystalDiskMark results different on HDD seagate barracuda

[Rebdevl]

Hi all, i was testing my hdd with crystaldiskmark and i have at first very bad results in sequential read 19MB/s and 18MB/s on first try; second run i had always in sequential read 70MB/s and 71MB/s; then at third try the results returned to normal (like 212MB/s both). Is this normal? In other tests before it always displays 200MB/s+ speed. Can be due to the cold? Thanks for answers. PS i've ran crystaldiskinfo and it says that is good the hdd
