Important Notice

• 4K QD32 write test may conflict with Norton and Avira security software, so please stop real time scanner before runnning test temporarily.
• “MB/s” means 1,000,000 byte/sec.
• The result depends on Test File Size, Test File Position, Fragmentation, IDE(PATA)/SATA/RAID/SCSI controller and CPU speed etc…
• In a part of SSD, the result depends on test data(random, 0fill, 1fill).
