NVMe vs SATA SSD | Speed & Boot time Comparision!

NVMe denotes Non-Volatile Memory Express. NVMe, a host controller interface specification, uses a PCIe bus to connect SSDs to a server.

The primary advantage of NVMe SSD is that it is amazingly fast.


For example, the 1TB Samsung 860Pro, a 2.5-inch SSD, has a maximum read/write speed of 560MBps. Its successor, the NVMe 960 Pro, displays a top speed of up to 3,500MBps. It is thus six times faster.

SATA, aka Serial ATA, was introduced in 2000 as an improvement to the existing parallel ATA technology. It was sufficient for HDDs and SSDs, as well. While HDDs could achieve speeds up to 50 to 120MBps, the SATA SSDs maximize at 550MBps. SATA has three versions, with SATA 1.0 capable of read/write speeds up to 150MBps, and the SATA III capable of hitting speeds up to 600MBps.

Here is the NVMe Vs. SATA SSD comparison.

InterfaceIt can be used in flash environments alone. Hence, it can connect to SSDs and not HDDs.SATA can accommodate both SSDs and HDDs.
PerformanceIt exhibits a queue depth of 64,000 per command while supporting 64,000 queues.SATA has a single command queue and a queue depth capacity of 32
Use CaseNVMe is suitable for business-critical applications with transaction-heavy databases.Comparatively, SATA is suitable for high capacity, low availability, and sequential reads.
CostNVMe is expensive compared to SATA. However, the prices are stabilizing now.SATA is less expensive compared to NVMe.
