Edit3: Remountable/movable flexible storage for DO instances is what this gives you and it's kind of pricey. The comparison to B2 is not valid. Leaving the original mess for posterity. --- TWENTY times (edit) the price as B2 from Backblaze ($.10 vs $.005 per GB per month). It is one of the more expensive ones. But that gets you two things: * (moot See edit 2) SSD! (significant iops improvement) * (moot See edit 2) No…

Isn't it $0.10/GB/month? That would make it 20x the cost of B2.

This has been a much requested feature and I'm sure it will be very popular. I'm still reminded of this quote though:

"He was a bold man that first ran a production database on a brand new block storage service!"

Don't be confused: the article makes the mistake of comparing DOs new block storage service with other companies object stores. EBS is the competitor to this, not S3. Same for gce persistent disks and azure drives. Unfortunately this means the pricing comparison is just wrong.

Ohh

I like their straight forward pricing. $0.10 USD per GB per month. No IOPS limits. That said, how do you prevent a rogue droplet from going crazy and hogging up all of the SSD I/O?

They might limit IO speed (based on usage of previous 24h for example). Like how most cheaper AWS EC2 instances get their CPUs throttled after you're running CPU heavy stuff.

B2 is blob storage, like Google Cloud Storage or Amazon S3. What they have launched is SSD block storage, like Google persistent disks or Amazon EBS. (The TechCrunch article also got this confused.)

> Amazon EBS.

Not more like amazon EFS?

A bit pricey for the long term but great if you just need to add some disk space to your vm and don't need the other improvements more expensive vms give you.

I use DO mostly to compile stuff on Linux when i don't have access to a physical server, and storage size is always a problem.

This helps me with a nicer deployment setup. I was always keen on 'rebuild from scratch' rather than 'update stuff and hope you're idempotent and have captured all changes' but transitory data was always the problem. Now I can start building a new updated droplet and the only downtime will be that needed to detach and reattach the block storage containing the db etc.

Anyone see a flaw in this? (I know there are other ways to achieve similar benefits - my files could be on S3 and the database could be a separate droplet etc but these introduced various drawbacks and added complexity)

Unless I missed it, I saw "no need for complicated formulas to determine the overall cost for transactions or IOPs limit," which I do not read as "no IOPS limit." I was looking but could not find any word on performance.
