Amazon S3 and Wuala hard facts

Since 2 years I’m using Amazon S3 as cloud storage services and I’m quite happy with it. From time to time Wuala comes into my focus checking how stable the service becomes. Both differ in every technical aspect of their service but in the end they store files in the cloud.

This time I made a small test, to compare just the performance and technical aspects of the services. The simple test scenario was to copy a folder with 50 MB, containing 20 files over a DSL connection with 16MBit/s download and 1MBit/s upload bandwidth. The result was not a big surprise.

Upload 50MB:

Time (min:sec) Total (MB)
Amazon S3 7:24 52
Wuala 13:47 82

Download 50MB:

Time (min:sec) Total (MB)
Amazon S3 2:14 50,5
Wuala 2:27 54,1

The figures are simple to enough to see that Amazon S3 stores files in half the time compared to Wuala. Interestingly not because it has a higher performance (average transfer rate about 20% higher) but the total amount of data send over the net. Wuala uses P2P technology which stores encrypted file segments redundant on several clients (plus a central backup server) which results in more traffic. You can surely produce advanced performance tests, but they won’t get you something very different.

The price is compareable. For 10 GB you pay for both services per year about 15 GB though the comparison is distorted by the fact you get 2 GB free from Wuala per account and additional space for inviting friends or sharing your hard disk on one side and that you pay as you go with Amazon (wuala smallest offer is a 10GB package).

The reason why I’m still attracted by Wuala is the client. You have nothing like that for Amazon S3. Yes, JungleDisk is a good client software, but it

  • doesn’t work offline
  • needs a connection to the JungleDisk gateway to access Amazon S3 which makes me curious about security & privacy
  • nothing about sharing files with friends, notifications etc.
  • no security features like verify the integrity of my file

Wuala doesn’t have the write performance like Amazon S3 but you won’t mention the difference because the upload happens with both tools in the background. Wuala client provides:

  • perfect offline functionality
  • clear concept to ensure privacy (I trust it)
  • Swiss company with connection to university which has been bought last year by Lacie
  • collaboration features like group spaces, notification when someone added a file etc.
  • integrity check to your files
  • access to public cloud storage content published by other Wuala users

My personal conclusion is to give Wuala a try to exchange data with my family and friends.

  1. Luzius here, cofounder of Wuala. This is an interesting comparison, thanks. The additional upload volume comes indeed from the redundancy we already create on the client side. Feel free to send any additional feedback to support@wuala.com or file feature requests at bugs.wuala.com .
