SSD Write Endurance 25nm Vs 34nm

Also, the average speed went UP by 1.5mb/s since the big change in reallocated sectors...

Interesting... Personally, I am trying to understand what are the tradeoffs that have been made for these SSDs and this seems to be another clue. Assuming the SSD does not have any wear level algorithm, if you throw some write requests, you might get either a very high or a very low write speed depending on the state of the page and also a high WA. Now, if you add an advanced algorithm for wear leveling, this would add an overhead and will decrease the throughput because it would need to keep an updated list of pages that could be written. This seems easy at first sight but is not, because if you keep an ordered list based on least written pages, any free page gained would need to be inserted in a sorted order and this is a compute intensive task. Now spare area decreased significantly and the wear level algorithm is taking less time to execute and this would explain a sudden increase in write speed.
