Product Overview

AI-generated summary

At £260.83 ex-VAT for a single 4GB DDR4 SO-DIMM, this is one of those “it might be correct, but it’s pricey enough that you should question it” purchases. Synology-branded modules for specific appliance models tend to be marked up, and while you’re buying certainty (right type, right compatibility for that NVR/DVA3219), the cost-per-GB is hard to justify unless you *must* match Synology’s part for a supported deep-learning/NVR workload. If you’re troubleshooting stability or trying to get a specific configuration back to spec, it’s a sensible, low-risk fix.

Who should buy: teams running the Synology DVA3219 and only needing a small top-up, or anyone who values “plug it in and support stays clean” over shopping around for cheaper generic DDR4. Who should not: if you’re trying to improve performance broadly, 4GB is usually a limited uplift for modern camera/analytics workloads—at this price, you’ll often get better value by moving to a larger capacity kit (or upgrading the overall memory configuration as your platform supports). If you tell me the current installed RAM and your typical camera count/resolution, I can give you a more grounded view on whether this £260 module will materially help or just stop a warning light.
