Intel SSD 750 PCIe SSD Review: NVMe for the Client
by Kristian Vättö on April 2, 2015 12:00 PM ESTATTO - Transfer Size vs Performance
I'm keeping our ATTO test around because it's a tool that can easily be run by anyone and it provides a quick look into performance scaling across multiple transfer sizes. I'm providing the results in a slightly different format because the line graphs didn't work well with multiple drives and creating the graphs was rather painful since the results had to be manually inserted cell be cell as ATTO doesn't provide a 'save as CSV' functionality.

AS-SSD Incompressible Sequential Performance
I'm also keeping AS-SSD around as it's freeware like ATTO and can be used by our readers to confirm that their drives operate properly. AS-SSD uses incompressible data for all of its transfers, so it's also a valuable tool when testing SandForce based drives that perform worse with incompressible data.
TRIM Validation
The move from Windows 7 to 8.1 introduced some problems with the methodology we have previously used to test TRIM functionality, so I had to come up with a new way to test. I tested a couple of different methods, but ultimately I decided to go with the easiest one that can actually be used by anyone. The software is simply called trimcheck and it was made by a developer that goes by the name CyberShadow in GitHub.
Trimcheck tests TRIM by creating a small, unique file and then deleting it. Next the program will check whether the data is still accessible by reading the raw LBA locations. If the data that is returned by the drive is all zeros, it has received the TRIM command and TRIM is functional.
And as expected TRIM appears to be working.

Does the Plextor use NVMe?Sushisamurai - Saturday, April 4, 2015 - link
I mentioned this on twitter with you already, but Dead Rising 3 on a HDD versus a NVMe SSD comparison would be nice :) would save me the work of doing it and testing it on my own :pAntonAM - Monday, April 6, 2015 - link
I don't understand why both drives have the same endurance if one of them have 3 times more flash? Is it endurance of something else?emn13 - Monday, April 6, 2015 - link
The endurance figure is also *really* low compared to other drives - it works out to around 128TB of total writes - that's on the order of 50 times less than an 850Pro (which is slightly smaller).I'm hoping this is just a really stingy guarrantee, and not representative of the actual drive - otherwise I'd really, recommend against using it.
I mean, running the anandtech destroyer benchmark with its close to 1TB of writes would use up your write-allowance for the next two weeks (put another way, it's cost around 10$ in relation to the 1k drive cost).

So how does this compare to the Kingstone HyperX Predator that was recently reviewed and I recently purchased?!eliz82 - Tuesday, April 7, 2015 - link
any chance of testing Kingston HyperX Predator PCIe SSD ?SanX - Tuesday, April 7, 2015 - link
Put down the drain all flash trash and start making full power loss protected ramdrives with flash/harddrive backup. Would be cheap by this time if not slow selfdedtroying flash garbage lying on the way.gospadin - Tuesday, April 7, 2015 - link
In other words, 100x the cost for a marginal improvement in performance?Rustang - Wednesday, April 8, 2015 - link
1) Why would you post a review of a Intel SSD 750 PCIe SSD solution without benchmarking it against the other state of the art Intel PCIe SSD Intel DC P3700 solution?2) Why would you put up sequential/random read/write graphs with pull-downs to display the different hardware results instead of efficiently putting all of the hardware results on ONE graph?
