970 pro raid 0 diskmark3/1/2023 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. QuickBench is another great test to show bandwith.Popular Now: UFO expert says new 'alien' sightings will soon erupt across UK Insight: I had back surgery a week ago and time at my standing test bench is limited. QuickBench is another great test to show bandwith. Highpoint 7101A 2xSM951 ** FASTER THAN 3X SM951 in 7101A**Īmorphous Disk Mark (FREE - GO GET THIS ONE) Perhaps I need to reformat the array with a different block size. Using a Software RAID 0 setup for the Amfeltec Squid, the Highpoint 7101A is about 25% SLOWER than the Squid. Allowing near PCIe 3.0 speeds from our aging mac pro. Moving them across to the 7101A, some interesting results came to light:Īddressing a single SSD at a time, the Highpoint 7101A is MUCH FASTER than the Amfeltec Squid. I was able to tear down the Amfeltec Squid 2.0x4 this morning, removing 3 SM951's and their heatsinks that are setup in a software raid. It’s clear the HighPoint 7101a brings a new level of PCIe NVMe / AHCI Sata Express performance to the 4,1/5,1 that’s unattainable with any other controller. Whilst the 7101a usually costs $400, a qty can be found at enthusiast pricing on Amazon for $275.
