It will be tight, but probably possible. Here are some issues...

Writing 10GB/hour to a disk is pushing the limits. Hardware RAID with buffering and striping would help.

How many rows per second? Can you batch up the rows? A batched insert of 100-1000 rows will work much faster than individual inserts.

What do you mean by 0.05s?

Indexes could kill the project; please SHOW CREATE TABLE. We need to discuss the indexes in more detail. Along with that, we need to discuss the ultimate SELECTs.

What will be done with the data? Can it be summarized _before_ inserting it? If so, let's focus on how to do that efficiently. You may not need to keep the data that long, or perhaps not in a bug table, or perhaps not at all.

Otherwise, PARTITION with either MyISAM or InnoDB, together with ALTER PARTITION to drop partitions after a few days, should work nicely.

How much disk space do you have? Sounds like you need a few terabytes!

MyISAM is usually 2x-3x smaller than InnoDB, so you may have to go with MyISAM.
