We feel Futuremark's Consistency Test is the best test ever devised to show the true performance of solid state storage in an extended duration heavy workload environment. (Internal drive maintenance: Garbage Collection (GC)) The test reports the performance level at the start, the degraded steady-state, and the recovered state, as well as the number of iterations required to reach the degraded state and the recovered state. In the second part, the recovery of the system is tested by allowing the system to idle and measuring the performance after 5-minute long intervals. In the first part of the test, the cycle continues until a steady degraded level of performance has been reached. Between each repetition, the storage system is bombarded with a usage that causes degraded drive performance. We partition the drive/array as a secondary device for this testing. Each test runs twice for 30 seconds consecutively, with a 5-second ramp-up before each test. Disk response times are measured at an industry accepted standard of 4K QD1 for both write and read. We use Iometer to measure disk response times. Version and / or Patch Used: Iometer 2014 Now let's see what performance looks like at the opposite end of the spectrum, QD1, with our disk response testing. At enterprise queue depths, Intel's 750 delivers superior write performance. This is the effect of RST write-back caching and is a very good example of why you want to enable it. We notice that in the case of our dual 512GB 950 Pro array, the array is capable of pumping out nearly three times the performance of a single 512GB 950 Pro. We do this just to see what the maximum attainable IOPS from our configuration actually is. We run this test at QD256, which is a queue depth that a consumer SSD will never see. The third run is a Vantage HDD test with the test drive attached as an empty secondary storage device. Steady state testing simulates a drives performance similar to that of a drive that been subjected to consumer workloads for extensive amounts of time. The second run is with the OS volume written into a "Steady State" utilizing SNIA's guidelines. The first run is with the OS drive 75% full to simulate a lightly used OS volume filled with data to an amount we feel is common for most users. An example of a marked difference in scoring on the same drive would be empty vs. This allows us to see a marked difference between scoring that other trace-based benchmarks do not exhibit. What we see is the raw performance of the drive. The reason we like PCMark Vantage is because the recorded traces are played back without system stops. We categorize these tests as indicative of a moderate workload environment. Benchmarks (Trace-Based OS Volume) - PCMark Vantage, PCMark 7 & PCMark 8 Moderate Workload Model With our synthetic testing out of the way, let's take a look at our moderate workload testing. We will briefly go over the settings we used to create a bootable PCIe array: We would like to thank ASRock, Crucial, Intel, Corsair, RamCity, IN WIN, and Seasonic for making our test system possible. Drivers: Intel RAID option ROM version 14.OS: Microsoft Windows 10 Professional 64-bit - Buy from Amazon.Power Supply: Seasonic Platinum 1000 Watt Modular - Buy from Amazon / Read our review.Case: IN WIN X-Frame - Buy from Amazon / Read our review.Memory: Corsair Vengeance LPX DDR4 16GB 3200MHz - Buy from Amazon.Cooler: Swiftech H2O-320 Edge - Buy from Amazon / Read our review.CPU: Intel Core i7 6700K 4.7GHz - Buy from Amazon / Read our review.Motherboard: ASRock OC Formula Z170 - Buy from Amazon / Read our review.Test System Setup and Drive Properties Jon's Consumer SSD Review Test System Specifications When it comes to random performance, which translates to better real-world performance, Z series systems have a clear advantage as illustrated by these benchmarks run on an Intel P3608.įinally, a close-in view of the drive's 512MB LPDDR3 Samsung DRAM cache package. X99 delivers excellent sequential performance, but that isn't nearly as important as random 4K performance. So why not just go with X99 and utilize some of X99's 28-40 CPU lanes for your PCIe SSDs? First, you can't have a bootable PCIe array and also because X99 cannot deliver as good of SSD performance as Z170 whether it be a SATA array or a PCIe array. Second, when routed through the Z170 chipset, you don't give up any of the very limited number of PCIe lanes (16) available on a Z170 based motherboard. First and most importantly, you can have a bootable PCIe array. While DMI 3.0 doesn't deliver enough bandwidth to fully exploit all the performance available from three 950 Pro's, it does have a clear advantage over standard PCIe slots in two ways.
