It also contains a Gigabyte GC-Alpine Thunderbolt 3 card, and Softperfect Ramdisk 3.4.6 for the 48GB read and write tests. The PCIe 3 tests utilize Windows 10 64-bit running on a Core i7-5820K/Asus X99 Deluxe system with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (Nvidia) GT 710 1GB x2 PCIe graphics card, and an Asmedia ASM3242 USB 3.2×2 card. Buying a PCIe 4 drive for a PCIe 3 PC is a waste of money unless you plan to take it forward with you to a newer PC. I’ve included it because, well, I’ve been asked to by readers. Note that the lighter gold is the KC3000’s performance over PCIe 3. Still, as you’ll see below, the KC3000 is the fastest of the three in CrystalDiskMark and our 48GB transfer tests-though only by a gnat’s eyebrow. It’s so close, you should buy on price and other factors. Indeed, the difference in speed between the KC3000, Corsair, and Seagate FireCuda 530 is hardly worth mentioning.

The numbers rolling out of the benchmarks and off the stopwatch for the KC3000 were hauntingly familiar-I just saw them from the aforementioned Corsair MP300 Pro XT. The only fluctuations of note were exceedingly minor and occurred during the 450GB sustained write. How the amount of TLC as SLC required is determined wasn’t disclosed, but whatever is being done, it’s being done extremely well.

Secondary caching is the main TLC employed as SLC, i.e., data is written to it as a single voltage level (one bit), rather than one of fifteen (three bits).
