2025: QLC-Based NVMe SSD Rollout Results

ITGLOBAL.COM summed up the implementation of drives based on QLC NVMe SSD in its own infrastructure. In the year since the launch of the current disk policy, more than 30% of all new cloudy projects for data storage customers have been implemented using this technology. QLC drives have made it possible to optimize customer costs and increase the efficiency of processing tasks with intensive reading. data This was announced by ITglobal.com on August 20, 2025.

From 2008 to 2019, ITGLOBAL.COM used hybrid systems based on HDD SAS with a speed of 10 thousand revolutions, accelerated by an SSD cache for hot data. Then the provider completely switched to All Flash architecture based on TLC drives, introducing deduplication and data compression technologies, as well as Quality of Service systems for load management and solving the problem of "noisy neighbors."

The introduction of QLC NVMe SSD was a natural development of DSS and allowed to create a three-level architecture for different types of loads. Capacity Flash layer based on QLC technology provides cost-effective storage for tasks with moderate IOPS requirements. QLC (Quad-Level Cell) stores four bits of data in one memory cell, which increases storage density and reduces terabyte cost. Storage systems on the TLC continue to serve high-load applications.

In the cloud infrastructure, ITGLOBAL.COM QLC NVMe SSDs are used for read-dominated tasks - development and testing environments, VDI environments, Kubernetes clusters, CI/CD pipelines, as well as for storing backups, logs and. media content These loads have moderate IOPS and latency requirements, but require cost-effective, scalable storage. Drives with QLC technology are used as part of. storage systems ITPOD

The results of the year show that the QLC NVMe SSD has successfully occupied a niche in our cloud infrastructure. A tiered storage architecture allows each type of load to reside on an optimal infrastructure. For high-load databases and critical applications, we use TLC drives, and for development environments, analytical systems and less demanding tasks, we use more affordable QLC solutions. This gives customers the opportunity not to overpay for excess productivity, "said Evgeny Svidersky, director of the ITGLOBAL.COM cloud business, ITG Corporation.
