NVMe also offers performance across multiple cores for quick access to critical data, scalability for current and future performance and support for standard security protocols. 2014.)īy taking advantage of PCIe, NVMe reduces latency, enables faster access, and delivers higher Input/Output per Second (IOPS) compared with other interfaces designed for mechanical storage devices. (Source: “All About M.2 SSDs,” Storage Networking Industry Association. For sequential workloads, NVMe delivers 2X the performance of SAS 12 Gb/s, and 4X of SATA 6 Gb/s. As a result, NVMe delivers 2X the performance of SAS 12 Gb/s, and 4-6X of SATA 6 Gb/s in random workloads. This streamlines the storage device stack, completely eliminating much of the complexity and layers present in SATA protocol stacks. One great feature of PCIe is its direct connection to the CPU. This interface leverages existing PCI Express ® (PCIe ®) technology to efficiently support the growing bandwidth needs of enterprise and client systems.Īlthough PCIe basically functions as an interconnect linking motherboard-mounted peripherals like graphics or wireless network cards, its suitable high-bandwidth bus technology is ideal for today's fastest SSDs. NVMe™ is an interface specification developed specifically for NAND flash and next-generation SSDs. To narrow the widening gap between fast CPU/DRAM and slow storage, Non-Volatile Memory Express or NVM Express ®, also known as NVMe ™, was developed by leading technology manufacturers. SATA does not support high levels of expansion, as most servers can accommodate fewer than six SATA devices. AHCI was optimized for rotating media, resulting in high latency when used with faster storage solutions that do not have mechanical parts, such as SSDs. SATA uses the legacy protocol Advanced Host Controller Interface (AHCI), to connect the CPU/memory subsystem. However, its latest generation is already almost a decade old, and its transfer rate is capped at 6 Gb/s. Serial ATA (SATA ™ ) is generally the least expensive and most extensively used SSD interface today. Compounding the problem is that the faster, higher-capacity solid state drives (SSDs) today still widely use interfaces designed for slower mechanical drives. Mechanical storage drives such as hard disk drives and the interfaces connecting them, however, have trailed behind. Over the years, CPU and DRAM technologies have been continually improving and increasing speeds to meet escalating data-hungry requirements. As users create more and more data, we will not only need space to store it, but also higher throughput and faster response times to access data. The deluge of data being created every day shows no sign of abating. SATA: It's Time for NAND Flash in the Fast Lane Once I install it, I'll probably come back and ask for help in the transfer process, as it's something I've never done before.NVMe vs. While there probably won't be a noticeable difference in load times (as you mentioned), it won't be any worse, plus it will give me a lot more space to work with. So I plan to make it my dedicated gaming drive and transfer all my games, game launchers, and mods to that drive. A highly rated 2TB NVMe drive, with a heatsink, at $220 off the normal price, so it seemed like the perfect time to upgrade (I can rationalize just about anything when it comes to gaming). So I splurged and bought that Seagate 2TB NVMe drive listed in the PCG Article last night. There are also some games that I like to mod and those mod folders often contain more data than the game itself. I like to keep some games permanently installed, and some games, especially newer games can easily take up 60+ GBs of space. I would never have thought a few years ago that I would ever need to worry about drive space with a 1TB drive. Click to expand.Drive space has become an issue.
