Performance Comparisons – TRIM Speed
Thanks to the plethora of data we have at our disposal from the new suite, I can derive some additional interesting data that nobody seems to have been paying any attention to yet. Have you ever deleted a large file and then noticed your system seem to hang for some time afterward? Maybe file moves from your SSD seemed to take longer than expected?
That's your problem right there. In the above capture, a 16GB file was deleted while a minimal level of background IO was taking place. Note how that IO completely stalls for a few seconds shortly after the file was deleted? That's a bad thing. We don't want that, but to fix it, someone needs to measure it and point it out. Enter another aspect of our new testing:
Latency Percentile data was obtained while running a 'light' (1000 IOPS) workload in the background while files of varying sizes were deleted. The amount of latency added during the deletions was measured, compared with a baseline, and correlated with the sizes of the deleted files. The result is how much latency is added to the active workload per GB of file size that was deleted. In short, this is how long you may notice a stutter last after deleting a 1GB file.
760p did well, offering a marked improvement over the 600p, but it lagged behind the 960 EVOs, which have a near-negligible performance impact from TRIM.
This is another result sourced from a different segment of data. While our suite runs, it issues a full drive TRIM several times. Some of those times it is done on an empty SSD, while other times the SSD was full. Any difference in time taken is measured and calculated, normalizing to a response time per GB TRIMmed. In short, this is how long an otherwise idle SSD would hang upon receiving a TRIM command for a 1GB file. These times are shorter than the last chart because the SSD controller does not have to juggle this TRIM with background activity and can throw all of its resources at the request.
The 760p turned in similar results here – measurable, but relatively small, and thankfully an even better improvement over the 600p.
Finally, it crazy how long
Finally, it crazy how long it’s taken to get a reasonable competitor to the Samsung NVME juggernaut! At least it’s competitive price and performance wise with the 960evo.
This is a very interesting
This is a very interesting NVMe M.2 drive but the 960 evo is barely any more expensive at this point. 10% cheaper isn’t going to make up for the large performance delta.
960 EVO offers only 3 year
960 EVO offers only 3 year warranty which is quite a difference. Yet I will not buy a single intel product anymore unless the performance delta favours them immensely, good bye asshole corp.
That’s why it didn’t get
That's why it didn't get Editor's Choice. It would need to have outperformed the 960 in more ways than it did for me to go that far in the recommendation. If the price delta is $10-20, I'd personally still buy the EVO today. Still a good showing from Intel through – the 960's needed some healthy competition.
“I’m awarding gold to the
“I’m awarding gold to the 256GB and 512GB models of the 760p. These products nearly match the current M.2 NVMe class leader, and win in some of our more critical metrics, all while coming in at a lower cost.”
Totally corrupt /s
Dude go get your tinfoil hat and play in the corner.
A white paper doesn’t lie about a product, it put the strengths on display and show when it would make sense to choose one product over another. Allyn is one of the best storage editors out there, of course they would go to them to write a third party paper. You wouldn’t go to LTT for this kind of in depth reporting, they aren’t geared for that type of work. Also why duplicate work or not use work you gained in the research of a product in your own sites review?
You seemingly don’t
You seemingly don’t understand how conflict of interest pertains to journalism. A conflict of interest exists regardless of whether this conflict ends up influencing Allyn’s review at PCPer. Ultimately, it is the responsibility of any proper journalist to keep a professional distance (read: financial independence) from the subject of their coverage.
This has nothing to do with whether Allyn should have been chosen over some other youtube reviewer (hint: no reviewer should conduct paid work for a vendor whose products they review). If you are a journalist/reviewer, you have the responsibility to ensure that you are not in any position where you stand to personally benefit from your professional conduct. It is absolutely unacceptable to be paid by a company (for real work), and fail to disclose this financial relationship to your readers.
This is such a blatant example of COI that I’m shocked they thought it would go unnoticed. To answer your question: if you were paid by a company (Intel) to perform work for them, you stand to benefit from them continuing to pay you, or provide you with other benefits (like privileged access to products, or early access). Adored’s video discussed how PCPer’s access to optane did not reflect the relative size and reach of their outfit (read: they were given privileged access to hardware that was not available to the rest of the press). This (indirectly) has monetary value, since it allowed PCper to produce content that other outlets could not feasibly produce. Unique content results in views, and therefore money. Readers have the right to know that this relationship existed, and PCPer knowingly chose not to disclose any such relationship. It’s extremely disappointing, and this is coming from a frequent consumer of PCPer content.
To be clear, we duplicate the
To be clear, we duplicate the work regardless. It would be extremely unlikely for any possible white paper work / other research work to use an identical test configuration as the test suite used for reviews, and even if it were, I'd do separate work for both sides anyway.
Shrout Research’s commercial
Shrout Research’s commercial conflict of interest makes this site in best case questionable. Sorry Allyn and Ryan, your credibility is in the gutter for now. 🙁
PCPer is now dead to me. In
PCPer is now dead to me. In nearly 35 years of IT work I have never seen such a serious conflict of interest as this one. Everything that now comes out of PCPer’s so-called journalists mouths will be nothing but meaningless blablabla to me. PCPer needs to be served with a Class Action Lawsuit, at the very least.

The only surprise is that the AMD fanboy community still watches AdoredTV after all his BS from the previous two years. You guys are seriously in love with siege mentality.

It doesn’t appear there is any spare area on these drives. Would it be worthwhile to overprovision them to say 250GB, 500GB etc ?
