Pardon my ignorance, but does this mean that the web interfaces -- and that includes the presently slloowww RoundCube interface -- are going to be faster overall for users?

No, The webmail only goes to disk when you open a message. The rest is stored in a database.

We will also be upgrading our database servers, so you will get a difference there. We are going to keep the whole database in RAM.

The storage on SSDs is included in the current subscriptions, yes.

Yes, RoundCube is a IMAP client, so that will be much faster.

It´s well known that SSD,s are better in performance but less secure if you delete something. In fact, as I know, it´s almost impossible to delete them without leaving some trace.

Great news about Dovecot

I am not sure that is true. You don't overwrite data if you delete something on spinning disks? You just delete the table that references the data?

Quite the opposite, it seems: http://en.wikipedia.org/wiki/Solid-s...ecure_deletion

We can ask our sysadmins for details, but this has never been raised as a concern in our thorough discussions leading up to this acquisition.

I read about it in many places some time ago, as something already tested.

http://nvsl.ucsd.edu/index.php?path=projects/sanitize

Some post about it:

Concerning the security of "erased" data:

The logical destruction of files isn't correctly done in some drives, even using the built-in commands. You can take a look at this site, from some group at USCD. They've published some papers about it.

The problem is somehow old: in SSD, you can't be sure you're overwriting the old information. So, manufacturers have implemented commands to do that. But not all them work as expected, especially if you can have access to the Flash chips.

So, if your question was about security (and not reliability), I would concern a bit more about SSDs.

jl66: Thanks for the link. It is somewhat theoretical however, as data will typically be deleted and overwritten multiple times as a normal consequence of data migration -- and the older data will eventually be unrecoverable.

In any event, our sysadmins are quite paranoid about data security and would never let a drive leave our facilities without making sure it is beyond recovery.

Thank you Geir.

I now remembered the first time I read about it, using Tails live-cd, in the Tails documentation.

Erased is something else than deleting. When you secure erase data on a SSD, you are using a built in function to wipe all data on the drive. Specifically in mobile phones running Android (they use NAND, and not complete SSDs), it did not work as well as expected. That is not true for most modern SSDs. There has been many technical papers about that issue after that report.

Also you dont secure erase a drive in a production environment with customer data on it. When a customer deletes some or all of their data, you delete that data, not secure erase the whole drive.
