We have already looked at a number of PCI Express based drives, with wide ranging price points and performance levels. Some of the drives use proprietary technologies, while others are simply SATA RAID configurations, bridged to PCI Express. Intel, however, recently released a whole new family of PCI Express solid state drives, the SSD DC P3x00, featuring an NVMe controller. NVMe is a low-latency, scalable host controller interface designed specifically for PCI Express-based solid state drives. NVMe (Non-Volatile Memory Express) offers a number enhancements over legacy interfaces, like support for parallel operations and support for up to 64K commands within a single I/O queue to the drive. NVMe also offers many enterprise-targeted features like end-to-end parity data protection, enhanced error reporting, and virtualization, among other things. All in all, NVMe can provide up to 6x the throughput of a SATA 6Gbps interface.
We’ve been testing one of the higher-end Intel DC P3700 series drives for a few days now and have all of the details for you here. Check out the drive and its specifications below, and then strap in as we profile its performance on the pages ahead...
