Advanced load bench-marking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting. TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features. The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Transfer speeds are displayed on the left with IOPS results on the right.Īnvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. so these are incredible speeds and you might want to use them in your database, especially the parts that requires too much. Also, there are many people using raid 0 on nvme drives and some of them has reached 33GB per second read and 28GB write speed. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Current NVME disc drives has around 3500 read and 3000 MB per second which is extremely high. The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. This just might result in a slightly faster system operation. Many might not notice but the low 4K random read of 86.97MB/s is very high in comparison to the norm and something very good to see. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.Ĭrystal DiskMark shows that throughput is very close to the money although we aren’t seeing anything close to the 1 mil IOPS as per spec. Check your wallet (and PCWorld’s guide to the best SSDs) and make the call.Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. But a 35 percent premium is hefty for a drive that’s not all that much faster than its rivals. After that i have 1000000X installed windows again and still. If you want the fastest M.2 NVMe SSD available, that’s the Samsung 970 Pro-no ifs, ands, or buts. Samsung magician performance test shows my 960 pro 500 GB read speed at 1800 and write speed at 1635 when its supposedly rated and tested at 3500 read and 2500 write. And the CrystalDiskMark 4K results with various thread and queue depths clearly indicate that performance is well-balanced for most end-user workloads. It was hardly a blow-out, but the Samsung 970 Pro proved fastest in nearly all the tests we ran. There is a very large margin of variation in this test. The 970 Pro was a bit slow in the folder write, but dominated in all the other tests. Would it generally be better to install 2x 250GB Samsung 970 Evo drives in RAID 0, or 1x 512 GB 970 Pro standalone Price is about the same. This allows for insane bandwidth when pairing two NVMe drives in RAID 0. Our real world copy tests, shown below, are designed simply to back up the conclusions of the synthetic benchmarks, and spot if there are any major drop-offs during heavy end-user scenarios. I'm building on an ASUS Crosshair VII AMD board which has two M.2 slots with a direct connection to the CPU. The 970 Pro didn’t win all the AS SSD tests, but it proved the better drive overall. Unfortunately for the 970 Pro, the 970 Evo’s street price is also lower too now with the 500GB drive at $200 and the 1TB version at $400. If you’re bargain hunting, stop teasing yourself with this review and go read about those. 2x 970 Pro m. The good news is the 970 Pro’s actual street price is a good clip lower at $250 for 512GB and $500 for 1TB. That’s a difference of around 35 percent. The Samsung 970 EVO, also announced today, and the WD Black NVMe, cost around $100 less per 500GB of capacity. So if you want the 970 Pro (admit it, you do) you’ll be choosing from the $330 500GB version or the $630 1TB version. With SSDs, fewer chips means fewer paths to shotgun data across, often resulting in slower write and read performance. There’s also no 250GB version, though that’s likely for performance reasons. But the upshot of using faster, less data dense (compared to 3-bit TLC) MLC NAND is that there’s no 2TB version of the drive. The drive uses Samsung’s 64-layer MLC NAND, and the company’s new Phoenix controller to make good use of it. Don’t bother with this drive unless you have those four lanes. “Up to” means it’ll use them if you’ve got them, but can still function with two, albeit at about half the speed. The 970 Pro is a M.2 2280 (22 millimeters wide, 80 mm long), NVMe drive that can utilize up up four PCIe 3.0 lanes.
