Performance Comparisons – Sequential and Random
Just as we did on the last page, I'll start us off with Sequentials:
Recall that all data points here are the result of cumulative sampling across multiple percentages of allocated space. If you see what looks like an outlier or a weird dip, rest assured that apparent aberration was repeatable and consistent.
The NX500 (light blue) does well here, but lower QD reads were noted to be considerably lower than competing units (more on the impact of that on the next page).
Now for random:
While typical usage rarely exceeds QD=8, we extend these charts out to 256 for PCIe / NVMe reviews (QD=32 for SATA) to evaluate manufacturers claimed performance maximums. Our exclusive burst test is the only way to properly evaluate the random write performance of caching SSDs. Note how the majority of SSDs (both NVMe and SATA) all start at a relatively low value at lower queue depths. Let's move onto the next page to get a better idea of exactly where these drives fall head to head.
This kills my Intel 750 400
This kills my Intel 750 400 GB in sequential, which matters not at all for my typical workloads. About the same or worse in random IOPS. Probably feels exactly the same in daily use. $320 price is not bad – Intel launched theirs at $400 and it’s still the same price today (luckily I got mine for $300 during a rare sale at Newegg).
I’d love to see a direct comparison review, but I’m sure these will sell better – cheaper and better looking. I’ll keep my Intel drive, because their reliability is legendary, and it just feels like it will last forever.

as nice as those are, if I had that money to spend on storage then i’d rather just get more cheap sata ssd(s), like a 1TB samsung 850evo for about ~ $340.
Funny, at the conclusion page
Funny, at the conclusion page I remembered you were reviewing the Corsair NX500, I was much more interested in the details of the new testing method. Excellent work Allyn!

gaming headsets are almost never good though. Just buy a hyperx cloud or sennheiser game zero/one
I had an old OCZ Z-Drive R4
I had an old OCZ Z-Drive R4 SSD with a bunch of unpopulated capacitor pads on the PCB too. Do you think they designed in some kind of power smoothing / filter stage or something and then figured the cost of adding tantalum caps to the BOM outweighed any noticeable benefit to the user?
Of course, that would be for
Of course, that would be for power loss protection on the enterprise version of the card, now that I read what Al wrote instead of just looking at the pretty pictures. That brings up another topic I find crazy, the UPS. Convert AC to DC to store it in a battery, then back to AC to feed it into the computer’s PSU, where it is converted again to DC to run all the circuits. Can’t make it any more better. Computers are solved, guys.
Yeah, it makes more sense to
Yeah, it makes more sense to just have a single version of the PCB, and add components as applicable for the enterprise version, etc.
Wow Allyn, that performance
Wow Allyn, that performance comparison history is legendary! Pulled out every SSD you could dig up in the office? You need to make that model list searchable so people can find this. A recent SSD review comparing sooooo many models is a rare find!

I kinda treat SSDs like Pokemon :). We definitely want to do better things with the data, but with this site design, we're limited to pics of charts.
