In this article, we will take a detailed look at SSD for VPS: what it is, what benefits it provides and who benefits from it. Also, we will clearly compare SSD on SATA 3 with NVMe storage devices, which are connected via PCI-e interface.
Modern virtual servers in most cases are equipped with solid-state drives. They are about 10-20 times faster than standard hard drives, which is a definite plus for the client renting the server:
If you aim to create a fast and convenient site or an online store, you should choose only a VPS on SSD. The only question is which type is better: standard SSDs with a SATA 3 interface, or solid-state drives with a high-speed PCI Express (NVMe) bus connection.
SSDs themselves are incredibly fast, and the limitations of SSD speed have so far been limited by the connection interface. Standard Solid-State Drives connect to the server using a SATA 3 interface, which has a maximum bandwidth of 600 Mbytes per second. That is, no matter how fast the drive itself is, the data transfer rate will be limited by this value.
NVMe on VPS, on the other hand, is many times faster, since the connection is made on a high-speed PCI-Express bus. These devices can queue more data thanks to access to more PCI-e lines, resulting in huge performance gains in sequential read operations, up to 6,000MB/s. Sequential write speeds of up to 4,500MB/s can be achieved, which is 5-6x faster than SATA 3.0 SSDs.
Single line transfer speeds will already depend on the PCI Express version, but PCI Express 3.0 is most commonly used, with a throughput of 15.8 GB/s on the x16 line. No more is required for today's SSDs because even the PCI-e 3.0 version provides excessive bandwidth for them.
If we compare SSD-based VDS with SATA 3 and NVMe in terms of key characteristics, we get the following picture:
Solid-state drives with NVMe technology benefit from lower latency and increased throughput. For this reason, VDS/VPS hosting on NVMe is much more advantageous for customers who want to achieve maximum performance for their application or web resource.
In addition to greater performance, VDS servers on NVMe provide a number of other benefits:
SSD-based VPS hosting is great for multi-threaded applications, large online stores and other companies that use heavily loaded relational databases. These drives will provide unprecedented performance and responsiveness for your needs.
