This is different from full entropy tests which use 100% of the drive and take them into a steady state. Our testing process for these benchmarks fills the entire drive surface with data, then partitions a drive section equal to 1% of the drive capacity to simulate how the drive might respond to application workloads. This allows us to repeat the same workloads across a wide range of storage devices, including flash arrays and individual storage devices. These workloads offer a range of different testing profiles ranging from “four corners” tests, common database transfer size tests, to trace captures from different VDI environments.Īll of these tests leverage the common vdBench workload generator, with a scripting engine to automate and capture results over a large compute testing cluster. While not a perfect representation of actual workloads, synthetic tests do help to baseline storage devices with a repeatability factor that makes it easy to do an apples-to-apples comparison between competing solutions. When it comes to benchmarking storage devices, application testing is best, and synthetic testing comes in second place. To keep the results within the family and to show scale, will be comparing to the WD SN770 and WD SN850X.
We are reviewing the 1TB version of the SN580. For our added BlackMagic Disk Speed Test performed in Windows, we use our self-built StorageReview desktop. We do this because many of the common consumer benchmarks don’t adequately capture end-user workload profiles. A large focus is put on drive latency across the entire load range of the drive, not just at the smallest QD1 (Queue-Depth 1) levels. NVMe is tested natively through an M.2 to PCIe adapter card in the edge-card slot. ✓ Western Digital® SSD Dashboard constantly monitors the health of your SSDįor database and synthetic testing, we leverage the Lenovo ThinkSystem SR635 server, equipped with an AMD 7742 CPU and 512GB of 3200Mhz DDR4 memory. ✓ Western Digital®-designed controller and firmware for optimized performance We will be looking at the 1TB model for this review. The SSD comes with a 5-year limited warranty. The mean time to failure (MTTF) rating is specced at 1.50 million hours. It also upgrades your firmware when available. To help with management, the SN580 comes with the Western Digital SSD dashboard which monitors the health, capacity, and temperature of the drive. For random reads and writes, WD claims up to 600k IOPS in reads and 750k IOPS in writes. This beats SN570 performance by 14 to 21 percent in sequential reads and 18 to 66 percent in sequential writes depending on the size of the drive. WD claims a sequential read and write speed of up to 4,150 MB/s (for 1TB and 2TB models).
#Blackmagic disk speed test results update#
This makes the interface update an improvement from the SN570’s PCIe Gen 3 interface, especially for OEMs trying to offer flash-based systems at an affordable price point. While most new SSDs coming to market on are a Gen5 interface, the bulk of the systems in the world still use a Gen4 interface. The SN580 features a PCIe Gen 4 interface and offers capacities from 250GB up to 2TB. The SN580 is part of the WD blue line, which features mainstream value SSDs for users who are on a budget that don’t need a lot of storage power. The WD Blue SN580 is the successor to the SN570 SSD.
