SSD Write Endurance 25nm Vs 34nm

Groberts101, have you actually read more than the last few pages of this thread? You seem to be completely unaware of Ao1's testing. And your description of throttled states doesn't sound right at all to me.

As Tony states on the OCZ forums a "fresh" state is mostly irrelevant. You always have to assume garbage collection and possibly TRIM on these drives. It's just part of the process. A direct result of one of the drawbacks of flash NAND. It might make sense to call that a "settled state" since the drive has settled in to where it should stay in the long run. IOW it has to start dealing with garbage collection and TRIM. Your claim that this is the Duraclass "life throttle" seems a bit silly to me. It isn't any kind of throttle. It's just the normal garbage collection process making itself known. What you called a "hammered state" didn't seem to exist in Ao1's testing, although I believe that Tony claimed that there is such a state. It again just sounds to me like inadequate garbage collection needing extra time to catch up. Perhaps this would equate to the TRIM pauses Ao1 noticed. Brief stutters essentially.

Despite what you claim, according to both OCZ and Sandforce there is supposed to be an (optional) genuinely throttled state which exists solely for warranty purposes. If you don't like the term "life throttle" perhaps you could think of it as "warranty throttling" instead. The only reason for this slowing down of writes (to around 6 MB/sec in the case of Ao1's drive) is to make at least some effort to prevent warranty claims for non-consumer uses or 24/7 writing. In Ao1's case it sometimes seemed to slow down reads as well. Did you see that in your testing?

You also claim that secure erase will reset life throttling. I am curious about exactly what data you are basing this on. In Aoi's testing it took about 30 TB of writes before life throttling started to rear its ugly head. Once throttling did appear secure erase had no effect with the tools he was using. What tools did you use for your secure erase and what were your before and after write speeds?

[Note: I find your rather unusual method of trying to quote someone by adding your own red colored text to the quote extremely confusing and difficult to read. I had to check back a couple of times to make sure that Ao1 himself had not actually written what you wrote. There is a quote tag for a reason you know. Even italics would be easier to read than text color changes.]
