Well, we've started the quest to find out how long an SSD can last. I'm using the Kingston SSDNow 40GB, a rebranded Intel X25-V and One_Hertz is using the new 320 Series 40GB SSD. I'll be posting updates every day, well, thats my intention at least :) This is the status of my SSD just before the test started. 114380
No one is ever going to write that much on an SSD on a daily basis that you exceed 1 PB host write.
A very common SSD (Crucial M4) has surpassed 750 TB host write. Spread it over 10 years (3650 Days) and you'd have
to write over 200 GB (the drive itself will have either 128 or 256 GB capacity) per day every day for 10 years and it will still function.
SSDs can take a lot of shit contrary to popular belief.

Originally posted by mark45 View PostWell frankly, sometimes it's even worse, it might take 3-4 seconds to delete a few files worth of like 6GB, while on a window$ system it takes less than a second to do the same thing, often in a blink of an eye.
The default FS is more tuned to small files and the usual day-to-day work.
(JFS and XFS are the usual recommendations for handling big files, but do benchmark.)

Originally posted by blackout23 View PostI never heard of anyone running into problems because his router wrote to much data to often to its flash storage.
Plus, with the transition from 3x nm to 2x nm, flash P/E cycles took a nose dive. From 10k to 3-5k. Who knows how things will be in the future?

btrfs will not do that. Any generic fs will not do that.

this is my first post. <3
just what android needs. a new filesystem for those cheap flash storage inside the phones and tablets, some of them aren't even extendable. SSD is a very different case since the controller chip itself have a mechanism to *minimize* wear and tear, thus needing the filesystem to only support the features such as TRIM to work properly, that is why there's no need to have a proper filesystem made for them.
