Memory got expensive in 2026, and this site holds no history of its own to show it: the tables below are today's prices only. The trend is TrendForce's. It reported contract prices for conventional DRAM up roughly 93% to 98% in the first quarter of 2026 over the quarter before, and on September 30 projected a further 10% to 15% rise for the fourth quarter. Which table applies to you is a matter of the NAS: of the models recorded here, 20 take DDR4 SO-DIMMs, 9 take DDR5, and 3 have memory that cannot be changed.

Contract prices are not shelf prices
TrendForce's figures are what manufacturers charge their largest customers. A retail module follows later and by a different amount, so the percentages above describe the direction, not what a given module costs today. For that, use the tables.
The practical point for a NAS is that a memory upgrade is no longer a small add-on to the purchase. Check your model's limit and slot count before pricing one: several models here have a single slot, so an upgrade replaces the module you already paid for.
