What is the difference between FREE and Professional versions? What is the difference between the Site and Enterprise license?Ī Site License allows for unlimited usage of the program at one physical location, whereas an Enterprise License allows unlimited usage at any of the purchasing companies locations worldwide. This complies with the US DoD 5220.22-M security standard. KillDisk Professional version suggests several methods for data destruction.įor example, in US DoD 5220.22-M method it overwrites all addressable storage and indexing locations on the drive three times: with zeros (0x00), complement (0xFF) and random characters and then verifies all writing procedures. To erase data it overwrites all addressable locations on the drive with zeros (FREE version). It uses Logical Block Addressing (LBA) access if necessary to clean FAT32 drives more than 8 Gb in size. How is the data KillDisk communicates with the system board Basic Input-Output Subsystem (BIOS) functions to access hardware directly. To update or re-download your KillDisk software go to the link below and follow the instructions: How to update my current KillDisk software online? If you want to use the program to wipe 5 computers concurrently, you would need 5 USB / floppy or CDs and therefore need a 5 user license. Each license allows you to use the program from a separate USB / floppy or CD. The software is licensed on a per USB / floppy or CD basis. Our tests give the results: 10GB in average per minute per pass on average computer configuration and disks which age is up to 5 years old.įor example, 2TB Toshiba disk has been erased on Windows platform with one pass within 3 hours and 32 minutes, 14TB WD disk - within 18h 53m.Īttached are real-test certificates for erasing:ĢTB Toshiba (manufactured in 2015 year) SATA III (6Gbps) 7200rpm disk with and showing the average speed of 9GB/min per passġ4TB WD (2019 year) SATA III (6Gbps) 7200rpm disk with and showing the average speed of 12GB/min per passĬertificate-X5G677ATS-Success-04-33-53.pdfĬertificate-X5G677ATS-Success-13-36-47.pdfĬertificate-Z2H2VXGT-Success-12-42-03.pdfĬertificate-Z2H2VXGT-Success-02-34-48.pdf HDD speed: RPM and SATA/SCSI/SAS type - the most important factorĭisk Controller speed: SAS (6Gbps/12Gbps), SATA III (6Gbps), SATA II(3Gbps), SATA I(1.5Gbps)įor most modern computers and disks (manufactured within the last 5-7 years) SATA III standard is supported, so erase speed is limited by HDD throughput (disk write speed) only.
