Hard drives on backorder for two years as AI data centers trigger HDD shortage — delays forcing rapid transition to QLC SSDs

The race to achieve AGI (artificial general intelligence) has pushed constituents to invest in and build data centers at a pace far outstripping our ability to make them. Manufacturers are struggling to keep up with AI demand, and the ongoing DRAM shortage is proof of this, with memory kits costing more than double what they did just a few months ago. Now, DigiTimes is reporting that storage is taking a hit, too, with delivery times for enterprise-grade HDDs delayed by two years.

That means if a firm wants to buy large-capacity hard drives, the backbone of nearline storage, it has to wait 24 months due to long lead times. As the news cycle suggests, AI money doesn’t wait for anyone, so hyperscalers are now switching to QLC NAND-based SSDs to avoid these backorders. Picking QLC over TLC allows them to maintain costs while achieving sufficient endurance for cold storage.

However, hoarding QLC NAND creates its own shortage, since every cloud provider in North America and China is now lining up to buy it. This could lead to SSD prices rising worldwide, as most value-oriented models use QLC to save costs. In fact, DigiTimes claims that production capacity for QLC is completely booked through 2026 at some NAND manufacturers.

Therefore, given the current situation, QLC NAND is expected to overtake TLC in popularity by early 2027, marking a significant shift in the storage landscape. While enterprise-grade QLC SSDs would entirely power this pivot, Sandisk has already raised NAND prices by 50%, according to another DigiTimes report, after initially warning of a 10% increase two months ago.
