Yes, it is true that upload could be very fast dependent on the type of files and the specific files you are uploading.
DriveHQ Online Backup and FileManager software has many technologies to speed up uploading and downloading. Among these technologies are: (1) Compressed data transfer. If your file can be compressed, e.g. Text, Word, Excel or Database files, upload speed can be generally 3 to 9 times faser. (2) Caching: when files have been uploaded or downloaded before, the can be cached and skipped, so it results a super fast performance; (3) Resuming of interrupted uploads and downloads. When uploading/downloading a very large file, this feature makes it very reliable. (4) MagicUpload: upload could be extremely fast in some special cases when MagicUpload can be used. MagicUpload is a patent-pending technology developed by DriveHQ.
