Is it really a deal?
Enclosure discounts are easy to verify but say nothing about the total build cost, which the drives now dominate. Price the bays and the disks together before deciding whether a chassis cut is a saving.
For the cheapest row on this page we have recorded a low of CA$285.99 on 2026-07-21, across 14 days of our own checks.
2026 is a shortage year for both hard-drive platters and NAND, and several list prices were raised earlier in the year before being discounted during this event. A percentage off a raised list price is not the same as a low, which is why every row here is compared against what we recorded for that exact item instead.

Diskless enclosures from UGREEN, Synology, QNAP and TerraMaster, costed per bay rather than per terabyte, because an empty chassis holds nothing. Cost per bay is the number that actually compares a two-bay box against a six-bay one. The 2026 complication is that the drives to fill it have risen faster than the enclosures have, so a cheap four-bay unit can commit you to a far larger spend on disks. Synology's recent policy of restricting some features to its own branded drives is worth checking per model before buying.
Frequently asked questions
Why does this page show cost per bay?
Because a diskless enclosure has no capacity to divide by. Cost per bay compares a two-bay unit against a six-bay one directly, and the drives you add are priced on our capacity pages.
What will the drives cost on top?
Usually more than the enclosure in 2026. Large hard drives absorbed the supply squeeze while chassis pricing stayed flat, so a four-bay box filled with 20TB drives is overwhelmingly a drive purchase.
Do Synology units still accept third-party drives?
It varies by model and firmware, and some recent units gate features or health reporting behind Synology-branded disks. Check the compatibility list for the exact model before committing, because it changes the real cost of the build.
Why does this page rarely enter the index?
The gate needs at least three in-stock new enclosures sitting at or near a low we have tracked ourselves. The diskless field we price is small, so that threshold often is not met and the page stays out of the index until it is.
