Show us your SSD performance 2

I think you have misunderstood TRIM, multiple articles say the same thing even the wiki one you linked to.

It notifies the drive where invalid data is, thats it, nothing more. TRIM doesnt do any erasing. Its GC that does that.

Okay it deletes it. Semantics.

Third section down the page.> TRIM - Wikipedia, the free encyclopedia

Operation
The TRIM command is designed to enable the operating system to notify the SSD of which pages of data are now invalid due to erases by the user or operating system itself. During a delete operation the OS will not only mark the sectors as free for new data, but it will also send a TRIM command to the SSD with the associated LBAs to be marked as no longer valid. After that point the SSD knows not to relocate the data from those LBAs during garbage collection. This will result in fewer writes to the flash, reducing write amplification and increasing drive life. Different SSDs will act on the TRIM command somewhat differently so the final performance can also be different between different SSDs.
The command irreversibly deletes the data it affects.

That last line is misleading. what it means is because TRIM is going to mean deleted files are actually going to be erased much quicker than without TRIM then deleted files are unlikely to be recoverable. The bit you pasted clearly states that TRIM is telling the drive where deleted files so during GC they can be deleted, it doesnt say TRIM itself actually erases the files. We going to have to agree to disagree if we never going to agree with each other, to me it seems very clear tho.

TRIM = SSD knows where deleted files are and can erase before the pages are needed again for writes.
NO TRIM = SSD doesnt know where deleted files are until the OS tells it to overwrite those pages with new data. However manual trimming would still work in maintaining the SSD inactive pages.

Samsung 830 is the champ so far. Post #5104 last update.> SSD Write Endurance 25nm Vs 34nm - Page 205

(GiB) 3,718,760

For those that followed my earlier posts.
The Kingston 40MB (Intel X25-V rebranded) has topped 1PiB as of August 7, 2012.
It is one of the original SSD's and has been running since May 16, 2011.
I don't have the most recent write total.

It sure isn't the fastest but just keeps on working.

any thoughts on why the samsung 830 is doing so well with its apparent high write amplification which should increase wear? and sandforce doing poorly on the same tests with its compression decreasing wear?

Samsung makes everything in their SSD's, and they hand pick the components that go into them. They make the controller, as well as the firmware. It's no surprise these drives work as good as they do......it's Samsung
