Putting the speed of NVMe SSD into perspective

If storage devices were cars, in the amount of time it would take for a 15K HDD to travel the length of a 100-meter dash, a NAND Flash SSD could traverse the length of a marathon (26.2 miles). NVMe could travel from New York to Los Angeles and back in the same amount of time.

Don’t be fooled by NVMe SSD modules that run in SATA mode.

The Non-Volatile Memory Express technology on our servers takes advantage of PCIe’s bandwidth to create incredibly fast SSDs that blast SATA-based drives out of the water, fully exploiting the performance of high-end SSDs.

NVMe modules like the 960 EVO are engineered to take advantage of the unique properties of pipeline-rich, random access, memory-based storage. NVMe also reflects improvements in methods to lower data latency.

hddWhy settle for slow servers?

Dictionaries define “slow” as SCSI, SAS, PATA and SATA. Why? These are protocols that date back decades! They were based on hard drives that spun like tops – very mechanical in nature, thus prone to all sorts of failures and limitations based on rotation speeds and read/write heads.

NVMe SSD reduces I/O overhead

NVMe doesn’t just take advantage of lower data latency, it reduces I/O overhead, giving it the ability to process multiple long command queues. It only needs a single message for 4KB transfers compared to two, which increases server speed when processing tons of concurrent disk I/O requests.

NVMe logoNVMe SSD is a performance based solution

Traditional storage requires an ACHI (SATA) or SAS controller to connect mechanical hard disks to the PCIe bus, but NVMe eliminates that bridge and instead makes a direct connection.

SSD was a performance based solution because the latency or response time of the storage media improved drastically over mechanical drives, by as much a thousand times. Conversely, the bottleneck with under-performing NVMe is the SATA interface. When establishing a direct connection to PCIe, NVMe outperforms SSD by 6 times. This equates to server performance that the user can see and feel.

NVMe SSD modules running in SATA mode don’t deliver optimal performance

The Advanced Host Controller Interface (AHCI) is widely compatible with different softwares, but doesn’t deliver optimal performance when used with SSDs connected via the PCI Express bus. Why? SSD devices behave much more like DRAM than like spinning media, resulting in inefficiencies introduced by AHCI.
