Dropbox vs SkyDrive vs Google Drive

For the last few years I’ve been using Dropbox, a service that offers online file storage (often called ‘cloud storage’) and synchronisation. But in the last few weeks two new services have been launched by a couple of big names: Microsoft SkyDrive and Google Drive.

I’ve been looking into these two services and trying to decide for myself whether I should move away from Dropbox or use SkyDrive and/or Google Drive in addition to Dropbox.

For me the important things are:

  • Storage space for the price
  • Speed of synchronisation
  • Ability to choose which files to synchronise on which devices

I am assuming here that the terms and conditions of each of these three services is similar. And as that linked article to The Verge concludes: “what’s most important is how much trust you’re willing to give away as your data moves to the cloud”.

Here are a few of my findings and thoughts.

What is cloud storage and synchronisation?

For those who don’t already understand what Dropbox, SkyDrive or Google Drive are. A brief explanation.

So, if I save a file in my Dropbox folder it automatically gets uploaded to an online account From any web browser I can then log in to my Dropbox account and download any file that I’ve uploaded. That’s the ‘cloud storage’ bit.

Not only that, any other device (such as my laptop or work PC) that is connected to my Dropbox account automatically downloads that file into its Dropbox folder. That’s the ‘synchronisation’ bit.




Storage Month Year
2GB+ Free Free
50GB+ £6.25 £75
100GB+ £12.50 £150

(All prices are in US dollars, converted using Oanda, and rounded to the nearest 5p.)

Earn extra space: Dropbox users can earn more space for free by referring new users to Dropbox up to (I think) 32GB.

File limits: Files uploaded to Dropbox via the desktop application have no file size limit. Files uploaded through the website must be 300 MB or less.

Speed: When I drop a new file into my Dropbox folder it takes only a few seconds before the sync starts. Synchronisation time is fairly quick (you can customise whether bandwidth is limited or not for both upload and download).

Dropbox also supports LAN sync, which is brilliant! Basically, it speeds up synchronisation across computers on the same network by transferring files across the network rather than downloading them from the Dropbox servers.

Customisation: Which folders and sub-folders are synchronised can be fully controlled, which for me is essential. Dropbox calls this “Selective Sync”.

The desktop client offers a lot of options and tweaking. It is rather a joy to use, as is the website interface.

Integration: There is no built-in office application support with Dropbox. But there are a number of online apps and browser extensions that will sync with your Dropbox account.



Storage Month Year
7GB (or 25GB†) Free Free
+ 20GB £0.50 £6.00
+50GB £1.33 £16.00
+100GB £2.66 £32.00

(All prices are in GB sterling, paid yearly; monthly prices are shown for comparison.)

† Existing SkyDrive users were given the option to keep their existing 25GB when the service was revamped and relaunched in April 2012.

File limits: Files uploaded to SkyDrive via the desktop application are limited to 2GB. Files uploaded through the website must be 300 MB or less.

Speed: When I drop a new file into my SkyDrive folder it seems to take quite a while before the sync starts, noticeably longer than either Dropbox or Google Drive. Synchronisation time is fairly quick (you cannot customise bandwidth limiting).

Customisation: The only options that the desktop client offers are “Make files on this PC available to me on my other devices” and “Start SkyDrive automatically when I sign in to Windows”. When my PC first starts up it seems to take ages for SkyDrive to go through its initial checks and synchronisation.

Selective synchronisation is not available, which means that whatever you upload will always be available on each computer you synchronise with. For me this is a problem, I only want certain files to be available on my work PC, for example. Perhaps this will be made available in a future release.

Integration: What is really nice about SkyDrive is that I can open, edit and create Microsoft Office files (including OneNote) directly within SkyDrive using the Web app versions of Microsoft Office, which makes the experience feel familiar.

Google Drive

Google Drive

Storage Month Year
5GB Free Free
25GB £1.50 £18.00
100GB £3.15 £37.80
200GB £6.25 £75.00
400GB £12.50 £150.00

(All prices are in US dollars, converted using Oanda, and rounded to the nearest 5p.)

File limits: Files uploaded to Google Drive via the desktop application are limited to 10GB. Uploaded document files that are converted to Google documents format can’t be larger than 2MB.

An important point to note is that Google Docs (that is any file that is created as in Google’s proprietary format for documents, presentations, spreadsheets, forms or drawings or is uploaded and then converted into a Google Doc format) do not count against your total storage. So, you could effectively use a 5GB free account but also have, say, 10GB of files in Google Doc format.

Speed: When I drop a new file into my Google Drive folder it takes only a few moments before the sync starts; comparable with Dropbox, which is a good thing. Synchronisation time is fairly quick (you cannot customise bandwidth limiting).

Customisation: The only options that the desktop client offers are “Make files on this PC available to me on my other devices” and “Start SkyDrive automatically when I sign in to Windows”. When my PC first starts up it seems to take ages for SkyDrive to go through its initial checks and synchronisation.

Selective synchronisation is available, but not to the same degree of granularity as Dropbox offers. It would appear from the Google Drive preferences that only top-level folders can be selected or deselected. So if I want to sync my “Reference” folder, for example, with my laptop then I need to synchronise everything within it; with Dropbox I could select which sub-folders to sync. Perhaps this will be made available in a future release.

Integration: What is nice about Google Drive is that I can convert a lot of formats into Google Docs format, admittedly mostly Microsoft Office formats but that suits me fine. I can then view, edit and print them. I can also open PDF files directly in Google Docs, and I can attempt to use OCR to convert a PDF into an editable document.


Based on a 100GB+ account, on price per gigabyte Dropbox is by far the most expensive (SkyDrive 32p/GB per year; Google Drive 38p/GB per year; Dropbox £1.50/GB per year). Plus Dropbox doesn’t offer any integration with office applications in the same way that Microsoft SkyDrive and Google Drive do.

However, Dropbox has been in the game since September 2008 and has built quite a strong reputation for its stability, its ease-of-use, its speed and the features it offers. The drill-down selective sync and the LAN sync, in particular, are very useful for me.

While SkyDrive was officially launched in August 2007 it didn’t enjoy the same level of uptake or success that Dropbox did. One reason may have been due to the lack of desktop client.

The relaunch of SkyDrive in April 2012, only days apart from Google’s launch of Google Drive may change that but as it stands I think neither Google nor Microsoft’s desktop clients come anywhere close to the polish that Dropbox offers.

It will be interesting to see if Dropbox will continue to rely on its reputation and on the quality of its platform clients (remember Dropbox is also available for iPhone, iPad, Android and BlackBerry) or whether it will lower its prices as the competition from Google and Microsoft grows.


Truly selective sync: What a shame is that none of these three services allow me to select which folders on my PC (regardless of where they are) I can synchronise. I can only synchronise the contents of my Dropbox folder, and my SkyDrive folder, and my Google Drive folder.

What would be really nice is to be able to say: I want to sync everything within:

  • D:\Music\
  • E:\Photos\Family
  • F:\Code\Personal
  • etc.

Maybe in the future…

Encryption: And what about encryption? Currently none of these services offer any kind of data encryption

Your files are stored somewhere out there, in the cloud, completely unencrypted. Which means that if someone else got hold of them then they could read them with the minimum of effort.

While I don’t store any state secrets on my PC, it’s still the principle of the matter: ideally, I want my data to remain only mine and for me to choose with whom to share it.


A few months ago I upgraded to the 50GB account (approx. £6.25 per month) which meant that I kept my 4.75GB that I’d accumulated from my 2GB free account plus referrals and added an extra 50GB.

If either Microsoft SkyDrive or Google Drive allowed me to select which folders and sub-folders to synchronise, allowed me some control over the upload/download throttling speeds, and allowed me to synchronise files across my LAN (I often use my desktop PC and laptop at the same time) then I would likely move to a cheaper option.

If that was the case now then I’d move to Google, simply because of the lag time associated with the SkyDrive synchronisation. If they fixed that… well, I’ve already got 25GB free with them. That would save me £1.50 per year that I could otherwise spend on… I don’t know, a chocolate bar.

I use Dropbox a lot, and for now I intend to continue to use Dropbox as my primary cloud storage/synchronisation service.

I trust Dropbox.

Dropbox offers me the combination of speed and customisation at a price that I can afford.

But I will keep a close eye on both SkyDrive and Google Drive.

What have you decided about these, and perhaps other cloud-based services such as Apple iDrive?

  1. Hey Gareth,

    This is a hot topic right now and although I haven’t done the in-depth comparison you have conducted, I have used all of these applications, as well as Box.com.

    I am also a big fan of Dropbox and use it for pretty much everything. It is by far the most flexible application and I currently have 16GB all for free!

    Here is my little blog about Dropbox…http://www.chrismarr.co.uk/2011/07/27/dropbox-why-you-should-join-up-now/

    Thanks for this blog, it is good to know I’m still using the right application!



    1. Thanks for the comments. Good effort too for getting a massive 16GB for free. That’s a lot of referrals. I still do carry portable media, I’ve got a 16GB and a 32GB USB drive that I use mostly for carrying application installers, music files (quicker than synchronising with Dropbox for me), and a various snippets of code.

  2. Have you tried sugar sync? If so, what do you think of it? I changed from drop box to sugar sync because you get 5GB free rather than 2GB. Also, if you share a folder with someone it won’t use your storage space, it only uses the storage for the person who created the folder, unlike Dropbox.

  3. Rev, you are full of dropbox – way to far up your own tree – you need to re-evaluate your blog to include honest opinion, rather than selling something that is limited to personal opinion. And you pay for it too £75 pa is one hell of a lot of of chocolate bars.

    Skydrive and google can both sync folders, the former giving 25gb (free). Considering you are a user of cloud services, you should be well aware of the advantages of other free services over paid.

    Keep your eyes on adrive, mediafire and others offering 50gb and more for sync, folder management, share, release, encryption and macro access. (Single key stroke to you)

    Read more Rev, please

    Me 🙂

    1. Ah! Anonymous comments slagging me off for my own opinions – isn’t that what the internet was designed for. 😉

      You said, “[…] you need to re-evaluate your blog to include honest opinion, rather than selling something that is limited to personal opinion”.

      That sentence is quite honestly laughable. I’m not selling anything: this is my personal blog for my personal opinion. And for me, for my needs, at the moment, Dropbox works for me. I am happy with it.

      I did also say that I would keep an eye on the other products that I mentioned, and asked for opinion about other, perhaps lesser-known services.

      As for your patronising “[…] macro access. (Single key stroke to you)” comment that’s not a particularly accurate description of a macro. That sounds like a shortcut key, macros can offer so much more and can be mapped to a sequence of characters not just one.

      And who calls me “Rev”? Certainly nobody that knows me. A little more politeness please in future wolfblass. Thank you.

  4. One question interesting to me:

    In Dropbox a shared folder with other users counts as used disk space for you and each of the other users. How is this in Google Drive and SkyDrive?

    I know Wuala does not assign disk space to the users you share a folder with (it’s only you consuming space). Wuala encripts data. But only gives you 1GB and does not synchronize unless you turn Pro (by paying or offering space on your computer. Mine is not always up, so, I would have to turn to pay).

  5. Thanks for this comparison. I just wanted to add something that I had noticed after working for a while on converting several pdfs in google docs. For some reason the file limit isn’t the only limiting factor in that conversion.

    Quite often I’ve found that the OCR doesn’t get done over the entire document. Instead it stops at some point between 1/4 and 1/3rd the way through. Not sure why this is, but I do know it can’t be relied upon to take care of the whole conversion. Im thinking Im going to have to continue to rely on desktop based conversion, the cloud just doesn’t seem up to the task yet.

  6. Have you done any research on upload speed among competing cloud storage? I have been over 24 hours uploading 75 G of photos from my pc to a new skydrive account (Not even to 10 Gs yet).

    I went with microsoft skydrive based on the idea they would have the most secure none advertisement based service. Also, thinking that they would not go through my data and sell the information to advertisers. Anyway, would like to know what upload speeds are and if the services vary depending on their servers load. Again thinking that Microsoft would have great servers and would put forth a great effort in order to compete with Google. Obviously, Microsoft should have an edge for enterprises that use sharepoint, windows servers, and now windows 8 tablets and phones. I would like to know your thoughts on this.


  7. @José María Román I’m not sure, to be honest. It’s not something that I’ve considered as the people I need to share documents with all use Dropbox.

    @david b An interesting point about OCR. I must admit that I’ve never noticed any of the documents that I’ve converted being incomplete, but again it’s not a feature that I use myself, very often at least.

    @Jeff At the moment on Dropbox I’m using 11.1% of 107.1 GB (they upgraded me for free a few months back). It took me a good few days of leaving my PC on before the files were all uploaded. I’ve not done any research into upload speeds, but I know from experience that my ADSL connection isn’t too fast uploading, even if I get around a 6 meg download.

    I was impressed that Microsoft introduced selective folder sync in SkyDrive (they had to, really, to compete with other services). I may be tempted to move to SkyDrive, with whom I have 25GB free, and save myself £6 per month on Dropbox. Time for some testing, me thinks.

  8. I use SkyDrive for offsite backup – at £6 per annum for 20GB you just can’t beat it. But as noted there are two problems – having to have a special synchronisation folder on the hard drive, and security. I solve both with a single tool – I use SyncBack SE, which allows me plenty of options for selecting which folders I want to backup, and creates zip files in the synchronisation folder, encrypted with AES-256 and a long random key. Only changed files are updated and then uploaded. I expect other backup tools would do the same job. Note the Ts&Cs on SkyDrive make it pretty clear that if you don’t encrypt your files they will read them, if only to protect themselves from unsavoury content. So much for privacy.

    1. Yes, I was considering trying SkyDrive again, now that the sync client allows you to choose which folders to synchronise. I have 25 GB free with SkyDrive because I had an account before they remodelled the service. I also use SecondCopy which sounds like a similar tool to SyncBack SE. The only thing that’s holding me back, however, is the issue you raised about the Ts&Cs.

      I’ll see… it would certainly save me six quid a month.

  9. It seems no one here has heard of SpiderOak. It has *true selective backup and sync* and encryption. You should take a look. It’s also very competitive on price.

  10. Also SpiderOak is US based and that means that the laws of the US are applicable on the agreement you enter when you start using SpiderOak. Not saying that you should not but you should be aware of the differences in national law when it comes to your private data.

  11. Just forgot, SkyDrive also caused problems with my internet connection, bandwidth. Even my download speed decreased to around zero when SkyDrive was actually uploading files ???? Even more dissapointing is that Microsoft on it’s own forum does not take the problem serious. Even when I cancelled my SkyDrive subscription there was no motivation to improve the service. Furthermore, I can subscibe through the internet but when I want di-subscribe the procedure is not friendly at all. Shame on MS.
