Reminder that just a few weeks ago DigitalOcean rolled over on one of their customers and took down 38,000 websites after receiving a claim of infringement from the NRA against a parody site hosted on surge.sh: http://motherboard.vice.com/read/nra-complaint-takes-down-38...

I haven't forgotten about their little "we don't automatically zero-out SSDs, it's a feature, the customer is wrong" issue.

I also haven't forgotten about their private blog censorship debacle.

DO is not a serious player and should not be trusted.

What should be used for I/O throughput tests instead?

I usually use Bonnie++ when testing disk performance. http://www.coker.com.au/bonnie++/

Bonnie++ is heavily CPU limited and should not be used for disk benchmarking

It's the same price as AWS's General Purpose SSD EBS volumes. https://aws.amazon.com/ebs/pricing/

Yep.... Digital Ocean is much more competitive for instances though and out going bandwidth.

At the cost of significantly worse networking (VPC is fantastic), no object storage mechanism, no equivalent to IAM for instance permissioning, and no autoscaling (seriously? in 2016? I had to go look to make sure I wasn't misremembering--that they recommend something like DOProxy should make the lot of them faintly embarrassed).

DigitalOcean may have some value at the basement level of compute, but as a professional in this area there is literally no situation where I would use DigitalOcean right now because I value my time. AWS is already laughably cheap, the tooling is overwhelmingly superior, the resources available are better, and you aren't duct-taping together half-solutions and reinventing every wheel. (This is less an endorsement of AWS and more an endorsement of Not DigitalOcean; GCE is more than fine, Azure has some ugly bits around autoscaling that I don't like but you can get by.)

Spun one up and ran some quick numbers on a 100GB volume: root@ubuntu-1gb-nyc1-01:~# time dd if=/dev/disk/by-id/scsi-0DO_Volume_volume-nyc1-01 of=test.dat bs=1024 count=10000000 10000000+0 records in 10000000+0 records out 10240000000 bytes (10 GB) copied, 58.0655 s, 176 MB/s real 0m58.248s user 0m2.608s sys 0m41.604s Some quick observations: * Easy to add one when creating a droplet; by default they let you create v…

Thank you for telling us these details. I can't help but I note that you benchmark the drive with a block size of 1024. Minimum block size of a modern SSD is 4096, anything lower would just cause unnecessary load. Also if you want to benchmark a drive/block storage I highly recommend using fio.

Thx for the tip, I'll give that a try!

The same is true of "violation of the copyrights, trademarks, patents or trade secrets of third parties".

hence when a DMCA takedown is received, i don't see how DO is in a position to assess that something is or is not a violation. they simply follow the process outlined in the legislation.

> But that also assumes DMCA which, if memory serves, was not in play here.

Remember the old joke that I can't be a Democrat because I want to spend my own money, and I can't be a Republican because of what I want to spend my money on? If you chuckled at it, you should check Gary Johnson out. For real.

Does not support net neutrality. Game over for me.

But does support undoing NSA surveillance. If I'm going to pick tech issues to vote on, I care more about that one than net neutrality.

How many hours does it take to load 10TB and then reduce it to 5GB? ;)

Actually because I use the DO API and lots of small instances that work together, not that long. Right now I use S3, which blows because I hate the S3 cli and API, so I would love a better solution.

Not sure if it's much better for you use case, but Backblaze introduced an S3 competitor called B2 a few months ago.

Price calculation is straightforward:

- $0.005/GB/month for storage

- $0.05/GB download

- $0.004 per 10k downloads

There is a base free tier as well.
