Jon's Consumer Z270 PCIe SSD Review Test System Specifications




Jon's Consumer X299 PCIe SSD Review Test System Specifications



We would like to thank ASRock, Crucial, Intel, Corsair, RamCity, IN WIN, and Seasonic for making our test systems possible.



WD SSD Dashboard







SanDisk SSD Dashboard






Both Dashboards function the same. You can monitor drive status, performance, secure erase by making a bootable USB device, update firmware and monitor temps. The Dashboard is very functional, but we do not like the incessant ads rotating on the right side of the Dashboard, or that you need to make a bootable USB device to perform a Secure Erase. The 98% of drive life we have remaining shows that we wrote 12TB of data to each drive during our testing.



Drive Properties


WD Black 1TB M.2 NVMe SSD OS Disk 75% Full




SanDisk Extreme Pro 1TB M.2 NVMe SSD OS Disk 75% Full




The majority of our testing is performed with the test subject as our boot volume. Our boot volume is 75% full for all OS Disk "C" drive testing to replicate a typical consumer OS volume implementation. We feel that most of you will be utilizing your SSDs for your boot volume and that presenting you with results from an OS volume is more relevant than presenting you with empty secondary volume results.


System settings: Cstates and Speed stepping are both disabled in our systems BIOS. Windows High-Performance power plan is enabled. We are utilizing Windows 10 Pro 64-bit OS (Build 14393) for testing except for our MOP (Maxed-Out Performance) benchmarks where we switch to Windows Server 2008 R2 64-bit. Empty Windows 10 benchmark screenshots will also be shown on our MOP page.


We benched the WD Black on our X299 test system and the Extreme Pro on our usual Z270 test system.


Please note: When comparing our results to those of other review sites, look at page 10 Maxed Out Performance-Windows 10 which is done with the disk empty.


Benchmark screenshots will be shown WD Black (X299) first followed by SanDisk Extreme Pro (Z270).
