Please note DriveHQ has virtually unlimited network bandwidth and our servers are extremely fast. However, upload/download speed varies from time to time based on the Internet traffic. There are several things that can affect your speed:
(Please understand DriveHQ uses Bytes/sec, which is 8 bits/sec. Your 1.5mb upload bandwidth means the Max Upload speed is only about 180 KBytes/sec.)
(1) The network speed from your computer to your ISP; (local Internet speed)
(2) From your ISP to our data center; (Please test at different times/location as this speed is un-predictable and changes all the time)
(3) DriveHQ server speed and bandwidth; (which we can guarantee to be very fast)
(4) The size and types of files being transferred -- uploading large files are usually faster; Uploading large text, html, word, excel, bmp, tiff, pdf files are usually much faster than uploading JPG files. JPG files cannot be compressed and DriveHQ servers will also create thumbnails and preview images while uploading.
Please be assured that DriveHQ has massive servers and unlimited network bandwidth. The speed issue is almost never our problem.
Note cable/DSL service is asymmetric, meaning the upload speed is much slower than the download speed. Assume you have DSL / Cable modem with 384Kbps upload bandwidth, the maximum upload speed is about:
384K bps = 384/8 KB/sec = 48KB/sec. This is the maximum upload speed achievable with your broadband connection. (Note your download speed can be 5-10 times faster)
With a 48KB/sec maximum, usually you can only get a speed of 40KB/sec.
DriveHQ FileManager and Online Backup have implemented a lot of technologies to increase the upload/download speed:
(1) Data compression during upload. If you upload text/html/pdf/doc/bmp/wav/tiff/xls files, the speed can be 5+ times faster.
(2) Magic Upload: if you upload some common software files, tax forms, public files, the speed can be many many times faster.
(3) Extensive caching: DriveHQ client software never uploads/downloads files that has been uploaded/downloaded, so if you are backing up your files, it can supports incremental backup.
(4) Automatic resuming: if network is disconnected during uploading/downloading a very large file(s), then it can automatically resume if network re-connects.
Finally, DriveHQ Online Backup tries not to use all your bandwidth so as not to affect your other work. We believe it is more important to be reliable than the raw performance.
