    February report:

    At 78% capacity the drive's write speeds (particularly ones like 4K Q32T1 in CDM) have fallen off the face of the Earth. Absolutely massive drops in performance in some cases. Another anomaly to note is that CDM's sequential read speed is up ~100MB/s which happens on some days for some reason which I haven't been able to isolate. Really, I've tried, but haven't been able to find out why.

    February update:

    OS wipe and format. Due to some troubleshooting.
    I started to tinker with all kinds of things again :D
    Kept 16GB overprovisioning .

    @Steppzor

    Not to alarm you, but whats with your 4k Queued writing results (both 32 and 64 depth)?

    They're not much bigger than 4k writing itself. And I see that they used to be in line with whats expected.

    February Update - Everything has been running smoothly this past month. :)

    I've noticed some lower results from some of the testers, but you're at 94-95% capacity. Perhaps try moving some stuff to a different HDD and retesting?

    Compared to my first test, yes they are much lower, but i've kept the drive around 90%+ since then almoste and it's almoste been two years.

    My drive is also have no over provisioning. I think it is expected.

    I will try the suggestion from Elder and see if the results go back up :) Will post update later tonight.

    March report. If I'm not mistaken this is the 24th report making it just about 2 years. I'll continue with the benchmarks as long as needed.

    This month I deleted some contents dropping the drive usage to 70%. Benchmark results were abnormally abysmal so I did a manual trim and reboot. Now everything is as expected, and with the reduced capacity usage the performance is back to higher levels as well.

    So with the monthly benchmarks reaching 2 years I suppose I should share my thoughts. Overall I have little to say, the performance is good as expected, and the drive has aged relatively well; performance is very directly correlated to how full the drive is. That brings me to the only negative, as the drive goes over 70% capacity the performance falls off a cliff. I don't know if such a drop is normal for an SSD, but I know any SSD has performance drops as it reaches full capacity, particularly without over-provisioning.

    Over-provisioning will help sustained performance. Some drives it doesn't make a difference(i.e. sandforce) but 460 will definitely see a nice boost from 10-15~% OP.

    I usually OP around 20% if space isn't an issue.

    Windows 8/10 defrag = optimize drive. That runs trim command.

    March update:

    OCZ Vertex 460A already comes with 12% overprovisioning(up from 7% on 450). To which I add 16GB of my own overprovisioning.
    With these settings I am not seeing strong correlation of drive usage and its performance.

    March Update time. All has been well this past month. It hardly seems to have been almost 2 full years already. ;) the benchmarks are a little bit lower this time, but I believe that was due to having some extra background processes running at the time of testing.

    You can also do it directly through OCZ SSD GURU under the Tuner tab.

    I'll be updating tomorrow.

    March (+February) 2017 update.

    My apologies for skipping February update, but I could have sworn I did it. My bad. :(

    Anyway, the SSD is still good, after all this time, you can see life dropped to 97 and I'm pretty sure I have the biggest usage of it from all testers, so yeah, great endurance.

    If needed, I will keep posting updates of course.

    Also, there's a Trim button in the Maintenance tab of SSD Guru.

    April update:

    The performance breaking point for this thing really seems to be anything above 70%, even 71% results in notable performance drops.
