NVMe technology More IOPs With PCI express bus, NVMe drives are able to provide more IOPs (input/output operations) than the ATA interface used in early-gen drives. SATA interfaces provided 6Gbps throughput, whereas the later serial-attached SAS-3 interfaces were designed to offer 12Gbps throughput.
Now, NVMe technology is better than SATA and SAS regarding throughput as its PCIe interface offers a theoretical maximum of 32GBps (or a whopping 256Gbps) throughput with the latest PCIe 4.0 interface. No SSD currently saturates this connection (or even half of it), but this is a future-proof interface that has room for growth.
A good SSD drive, if connected to a fast SAS or SATA interface, might be able to read/write around 550 MB/s of data. Additionally, this same SSD might handle up to 10,000 IOPs per second.
But a good NVMe will be able to read/write around 3000 to 3200 MB/s of data and handle up to 640,000 IOPs.
In short, NVMe delivers up to 60X better IOPs performance and around 6X faster data transfer speeds.
High Queue Command Depth
NVMe drives use various queuing processes, whereas the SATA SSDs can only look after one command at a time with 32 queue command depth.
SAS interface offers 254 queue command depths. But the most incredible fact is that the new NVMe technology can look after a whopping 64,000 queues, and allow 64,000 entries per queue.
The greater the queue depth, the more requests for reading/writing can be queued up to be performed, allowing for better system responsiveness.
Scalable Technology
Since NVMe technology relies on the PCIe lanes and NOT a controller interface, it is scalable. As of now, the NVMe SSDs utilize 4 lanes, but they are able to potentially use all 16 PCIe lanes, which is forward-thinking.
Greener technology
As compared to traditional technologies, NVMe is much greener as it is able to use low-power mode to considerably reduce power consumption. This standby mode can reduce the power consumption down to 97% when the system is idle.
Industry-standard Security
NVMe technology’s command set is designed to support all the security container commands present in ACS, SAS, and ATA interfaces. This is the reason why NVMe is exceptionally compliant with industry-standard security measures.
Reduce Server Bottlenecks
Enterprises significantly rely on data for their websites, web-based apps, various SaaS products, and more. If your servers run on SSDs, you are likely to experience bottlenecks due to too many user connections or requests at a time, saturating your storage connection. This further leads to slower access to data, a slower loading time of web pages, and a degraded UX. Businesses might even lose customers due to inferior UX caused due to traditional SSDs.
NVMe servers address this problem with their high queuing abilities and faster read/write speeds.
Overall, it delivers excellent server performance and a seamless experience for both users as well as enterprise employees. We all know, better server performance eventually results in higher rankings in SERPs, a reduction in bounce rates, and an increase in conversions.
