Amazon S3
Chose Amazon S3 (Simple Storage Service)
I haven't been personally involved in the decision to use S3, but in comparison to Dropbox or Google Drive, this offers a less robust UI to modify things, while being a cheaper storage mechanism over the rest.
Chose Amazon S3 (Simple Storage Service)
Several issues with Dropbox where it was hard to set up in the application I was using and once it was set up it would work fine but then become disconnected for really no reason and the support from Dropbox was not that great. The one time that I had to bring back a backup it …
Chose Amazon S3 (Simple Storage Service)
Amazon S3 compared to all of these has the worst user interface. Drive and Dropbox as everyone knows is simpler and used for shared work files with a user-friendly interface. Google Cloud Storage and Amazon S3 are both in the same boat for large application files and great for …
Chose Amazon S3 (Simple Storage Service)
More robust and feature rich. Also more cost effective. However, the other options do lend themselves to be better at user friendliness. But if your technological and willing to look up help in the support knowledgebase you will do just fine and get a better product at …
Chose Amazon S3 (Simple Storage Service)
Amazon S3 has so much other functionality than it's competitors with so many more use cases. We use One Drive, Drop Box, Teams, Google Drive and other products for basic file sharing while working with partners and clients but that's kind of the extent of those products. S3 …
Chose Amazon S3 (Simple Storage Service)
S3 is still being used within our org but we have dialed it back heavily due to the inexpensive competing product CloudFlare offers. CloudFlare is basically free for the same functionality and the company has matured to the point where it is reliable and scalable, plus CDN …
Chose Amazon S3 (Simple Storage Service)
The main differences are that S3 files can be accessed publicly without having an account on the service so it is suitable for website assets, but the other services have desktop hard drive syncing applications so they are more suitable for sharing files to other staff in the …
Chose Amazon S3 (Simple Storage Service)
Since we use other AWS products, and since AWS and S3 are more familiar to developers, it is easier for us to stick with Amazon S3 over a similar solution like Google Cloud Storage.
Chose Amazon S3 (Simple Storage Service)
S3 is more of a niche product for hosting data within an IT infrastructure. The others are more end-user focused.
Chose Amazon S3 (Simple Storage Service)
Amazon S3 comes with all other services of AWS, all other services are very quick and secure with S3 storage, which is the best option for any application. Again, compared to other services like Azure or GCP, AWS provides more configuration and functions to host multi nature …
Backblaze B2 Cloud Storage
Chose Backblaze B2 Cloud Storage
Backblaze B2 Cloud Storage is the best of the bunch. It's priced better than the more expensive cloud based solutions and more robust than the file storage sites like Dropbox or Google Drive.
Chose Backblaze B2 Cloud Storage
Backblaze B2 offers more affordable storage per byte, supports the de-facto standard Amazon S3 protocol, and has free egress.

Chose Dropbox
I already answered this on the last question. Sorry.
Chose Dropbox
I think Dropbox is too expensive to be used as a high volume archive / backup
Chose Dropbox
Dropbox is my preferred software and data sync program. It excels in data storage, utility, price, and practicality. It’s universally accessible and has never caused any of my clients any issues. Automatic backup functions are limited, however, and could improve. Other than …
Chose Dropbox
Dropbox is the easiest and most straight forward of the bunch. I tried every similar service but always end up coming back to Dropbox
Chose Dropbox
Google Drive's interface is slow and clunky. Downloads take forever just to zip before you can download, and they unreliably tend to fail. Wasabi didn't seem trustworthy, and the price was too good to be true. Amazon was unintuitive and was going to require too much of a …
Chose Dropbox
Dropbox seemed to be broader and provided more storage than its counterparts. However, when compared with WeTransfer, the ability to send a very large file with a time limit would be nice, even if the recipient doesn't have Dropbox. The link feature helps, but by default, …

Amazon AWS
Amazon S3 is a great service to safely backup your data where redundancy is guaranteed and the cost is fair. We use Amazon S3 for data that we backup and hope we never need to access but in the case of a catastrophic or even small slip of the finger with the delete command we know our data and our client's data is safely backed up by Amazon S3. Transferring data into Amazon S3 is free but transferring data out has an associated, albeit low, cost per GB. This needs to be kept in mind if you plan on transferring out a lot of data frequently. There may be other cost effective options although Amazon S3 prices are really low per GB. Transferring 150TB would cost approximately $50 per month.

Providing the option of purchasing a much longer archive if desired or limiting the length of time in maintaining what's been saved is brilliant. It makes all the sense in the world. At the very least, unless the retention period is clearly mandated somehow, it causes a decision maker (especially a small business owner) to think strategically about what the storage needs truly are.

Dropbox
Dropbox is well suited for sending File Requests to clients to upload documents, and for me to send File Transfers to clients with documents for them to download. I can create separate files for each client, and also create files within files, which is very convenient and useful for my business purposes. In Dropbox I can also see all of the File Requests that I have sent and it shows me how many times they've accessed it and how many files they uploaded. I can also see all of the File Transfers that I have made and whether how many times the client has accessed it and how many documents were downloaded. It also sends me notifications if the clients haven't downloaded their files yet so I can remind them. Dropbox Sign has been very easy to use, and I have already stated what could be changed with it

Amazon AWS
  • Fantastic developer API, including AWS command line and library utilities.
  • Strong integration with the AWS ecosystem, especially with regards to access permissions.
  • It's astoundingly stable- you can trust it'll stay online and available for anywhere in the world.

  • I can share projects I need feedback on.
  • I can make projects available to editors so that they can do their work.
  • Dropbox is a place where I can store files that I can access from anywhere, even if I don't have my laptop with me at the time.

Cons
Amazon AWS
  • Web console can be very confusing and challenging to use, especially for new users
  • Bucket policies are very flexible, but the composability of the security rules can be very confusing to get right, often leading to security rules in use on buckets other than what you believe they are

  • Deleting the data is not simpler and requires manual intervention
  • Integration with third party tools needs much improvement as there are very less tools that can be integrated.
  • Fewer data centres presently that restrict options to meet specific geographic redundancy or data sovereignty requirements.

Dropbox is a user-friendly, easy tool which requires little to no skill and they offer a free version with a good amount of storage available. There are other file sharing tools available however at a cost. Dropbox free version I have used for years and it serves every purpose I need.

Usability
Amazon AWS
It is tricky to get it all set up correctly with policies and getting the IAM settings right. There is also a lot of lifecycle config you can do in terms of moving data to cold/glacier storage. It is also not to be confused with being a OneDrive or SharePoint replacement, they each have their own place in our environment, and S3 is used more by the IT team and accessed by our PHP applications. It is not necessarily used by an average everyday user for storing their pictures or documents, etc.

Since Backblaze added S3 compatibility a few years ago, it's become the most perfect online backup solution.
I also like their transparency in describing their platform and the reports of hard drive reliability are very interesting.
The free egress is priceless, too.

It works extremely well, and we have never had any issues with connecting or sharing files. It's very easy to use, and any team member can share, add, and delete files to a virtual drive. This is extremely helpful, and it's an amazing tool to use, ensuring everyone can connect and work together effectively.

Dropbox is really useful, you can access any file from anywhere and you can upload and even edit files online, but, sometimes it can be slow. Downloading, uploading, and syncing is a bit slow, it can take several minutes. Furthermore, the search engine for large amounts of data can be slow too and it is not powerful.

AWS has always been quick to resolve any support ticket raised. S3 is no exception. We have only ever used it once to get a clarification regarding the costs involved when data is transferred between S3 and other AWS services or the public internet. We got a response from AWS support team within a day.

Overall, we found that Amazon S3 provided a lot of backend features Google Cloud Storage (GCS) simply couldn't compare to. GCS was way more expensive and really did not live up to it. In terms of setup, Google Cloud Storage may have Amazon S3 beat, however, as it is more of a pseudo advanced version of Google Drive, that was not a hard feat for it to achieve. Overall, evaluating GCS, in comparison to S3, was an utter disappointment.

Backblaze is definitely the cheapest and most cost effective out of the 6 other services I've used in the past. For personal use, they are by and away the best service available. For business use, I believe they are a very strong contender to be the #3 guys behind AWS and Linode.

Return on Investment
Amazon AWS
  • It practically eliminated some real heavy storage servers from our premises and reduced maintenance cost.
  • The excellent durability and reliability make sure the return of money you invested in.
  • If the objects which are not active or stale, one needs to remove them. Those objects keep adding cost to each billing cycle. If you are handling a really big infrastructure, sometimes this creates quite a huge bill for preserving un-necessary objects/documents.

Backblaze
  • Difficult to quantify the peace of mind Backblaze B2 Cloud Storage services provides.
  • Based on the reported experiences of other Backblaze B2 Cloud Storage clients, recovery has been smooth. We have not yet had the need to use that function.
  • Because Backblaze B2 Cloud Storage's service has been seamless, I feel much more confident in their ability to deliver what they promise when we have the need to expand or enhance what we are purchasing from them.

  • When it works (usually if a client already has Dropbox, so they don't get the solicitation to sign up), it works flawlessly.
