Reference pages for these Synology models

CMR or SMR - the recording technology, with the manufacturer document it rests on
HAS5300-12THAT5300-16T

For first-party Synology drive decisions, HAT5320-24T covers the 24TB SATA HDD, HAS5320-24T covers the 24TB SAS HDD, and HAT5320 versus HAS5320 explains why interface and system class matter. If you are deciding between first-party qualification and a general enterprise drive, start with HAT5320 versus HC590 and the Synology drive policy.

What Synology covers here

We track 32 active Synology products, 26 of which have a buyable offer right now, across 4 categories: 8 hard drives, 7 NAS enclosures, 7 nas-upgrade and 1 home-switch. Capacities run from 4TB to 20TB, which is the practical range to plan around rather than whatever the manufacturer's full line-up contains - a capacity nobody stocks is not a capacity you can buy.

On interface, the catalogue is SATA-6G (6) and SAS-12G (2). That matters more than it sounds: a SAS drive needs a host bus adapter, a U.2 drive needs a backplane or an adapter, and neither will work in a machine expecting the other. Check the interface column on every row before you buy on price alone.

Where Synology sits on price

The cheapest Synology listing we can currently price works out at $58.33 per terabyte, which is well above the $43.70 median across every hard drives brand we track. That comparison is the useful one. A headline price tells you what a drive costs; the rate per terabyte against the category median tells you whether this manufacturer is where your money goes furthest today.

Concretely, that entry point is the HAS5300 12TB SAS at $699.99, while the largest thing they have in stock is the HAT5300 16TB NAS at 16TB for $999.99. Those two rows bracket the range: one is the cheapest way in, the other is the most capacity on a single unit, and the right answer is usually neither extreme.

New, recertified, or both

Synology appears here in both conditions - 17 new listings and 9 recertified or used - and they are genuinely different purchases rather than the same product at two prices. New carries the manufacturer's own warranty term. Recertified carries a reseller's, which is a different promise from a different company, and the discount is the compensation for that. Our recertified guidance covers what to check on arrival.

The seller matters as much as the condition, and the two are shown separately for a reason. A listing fulfilled by Amazon can still be sold by a third party, and in a market where prices have risen sharply that distinction is worth the thirty seconds it takes to read. Our channel and counterfeit guidance covers what to look for at the point of purchase.

Where to go from here

If you have settled on Synology, the table above is the whole picture and the cost-per-terabyte column is the ranking that matters. If you have not, the category pages are the better starting point, because they put this brand beside every other one we track at the same capacity rather than in isolation.

Frequently Asked Questions

On price, the cheapest current listing (HAS5300 12TB SAS) works out at $58.33 per terabyte against a $43.70 median across every brand we track in the same category. That is the comparison we can make from live data. Whether it suits your workload is a question the table cannot answer for you.

8 hard drives, 7 NAS enclosures, 7 nas-upgrade and 1 home-switch. Only products with a real listing appear; the catalogue is not the manufacturer's full line-up.

Both - 17 new and 9 recertified or used in stock right now, labelled per row (the cheapest overall is the HAS5300 12TB SAS). They are different purchases: new carries the manufacturer's warranty, recertified a reseller's, and the price gap is the compensation.

From 4TB to 20TB across what we currently track; the largest in stock is the HAT5300 16TB NAS. Availability at any single size moves week to week, so the table above is the authority rather than the range.
