BUFFALO LinkStation 210, 6 TB review

The same one-bay machine as the 4 TB LinkStation 210 with a larger drive in it, on a page identical but for the capacity line — which makes the two prices the only thing to compare.

By Jean-Benoit Buisson

This page and the 4 TB LinkStation 210 page on this shelf are the same ten bullets in the same order, differing in one line: the seventh, which reads 6 TB where the other reads 4 TB. Everything else — the closed system, the Japanese manufacture, NAS Navigator, the macOS 15 ceiling, the recommendation of the LS 700, the two-year warranty covering the drive — is word for word identical.

So the comparison is arithmetic. $230.99 for 6 TB against $192.99 for 4 TB: $38.00 for an extra 2 TB, which is $19.00 per terabyte at the margin against $48.25 per terabyte on the smaller unit. If the capacity is wanted, the step up is the cheaper terabyte by a wide margin. That is the whole decision between these two listings, and it is a decision the pages themselves cannot help with because they say the same things.

The first bullet carries the same contradiction as its twin: “Value NAS with RAID” on a machine the seventh bullet gives as one drive bay. One drive cannot form an array. The identical sentence appears on the two-bay LinkStation 220 on this shelf, where it is true, which is what identifies it as range copy rather than a statement about this product.

The same first bullet recommends the LS 700 range as having up to seven times the performance of the LS 200, and the same second bullet caps macOS compatibility at macOS 15 (Sequoia), directing macOS 26 buyers elsewhere. On a page this short the two sentences take up a meaningful share of it.

What is published is the posture: a closed system that keeps third-party applications out, SSL on transfers, folder-level access restrictions, NAS Navigator and PC backup software in the box, 24-hour support from the United States, and “Made in Japan”. What is not published is any hardware figure at all — no processor, no memory, no socket count, no port speed, no drive size, no decibel value, no watts.

The product record carries 1,102 g (38.9 oz), the same weight as the 4 TB unit, and 150 by 175 by 45 mm (1.77 in), where the 4 TB record carries 240 by 84 by 220 mm (8.66 in). One chassis, two capacities, two sets of measurements that cannot both describe it. The forty-five-millimeter figure in particular does not fit a drive bay for a 3.5-inch disc, so the record rather than the chassis is what wants doubting.

Where it holds up, and where it stops

Strengths

The cheaper terabyte of the two LinkStation 210 listings here: $19.00 for each of the extra two, against $48.25 per terabyte on the 4 TB unit
Arrives with its 6 TB drive fitted, so the price covers the storage as well as the box
Two years of warranty covering the hard drive, with 24-hour support based in the United States
The closed-system approach is stated as a policy rather than sold as a feature list
A country of manufacture stated, which nothing outside the LinkStation range on this shelf gives

Compromises

The first bullet offers RAID on a one-bay machine, the same sentence the two-bay model on this shelf uses truthfully
macOS compatibility stops at macOS 15, with the page directing macOS 26 buyers to another range
Not one hardware figure anywhere: no processor, no memory, no socket count, no port speed
The product record gives this chassis measurements that disagree with the 4 TB version of the same model at the same weight
One bay, so 6 TB is the ceiling as well as the capacity

Specifications

Bay count	One — stated in the title as 1-Bay and in the seventh bullet as one drive bay with the drive included. The first bullet calls the unit a NAS with RAID, which a single bay cannot provide
Drive interface	Not published on the listing as a size or a bus — the seventh bullet states 6 TB of capacity with the drive included, which is the only line on the page that differs from the 4 TB version of the same model
Solid-state slot count	Not published on the listing — no M.2 slot and no cache slot is named in the title or in any of the ten bullets
Processor	Not published on the listing — no chip, no core count and no clock speed appears anywhere on the page
Memory	Not published on the listing — no memory figure of any kind appears in the title or the ten bullets
Ethernet port count	Not published on the listing as a figure — the second bullet says to connect the unit to a router and counts no socket
Port speed	Not published on the listing — no figure in gigabits or megabytes per second appears anywhere on the page
USB ports	Not published on the listing — no USB socket is named or counted
Supported redundancy levels	None possible, and RAID nonetheless claimed — the first bullet offers a NAS with RAID and the seventh states one drive bay. The identical sentence appears on the two-bay model on this shelf, which is what marks it as range copy. Carrying on through a drive failure is a different thing from holding the data in a second place
Published operating system	Not named, and described as closed — the fourth bullet states a closed system to reduce exposure from third-party applications, with SSL encryption for transfers. The fifth names NAS Navigator, with NAS Navigator 2 for macOS 15 and earlier
Stated idle power	Not published on the listing — no figure in watts appears on the page
Stated acoustic figure	Not published on the listing — no decibel value and no claim about noise appears
Stated dimensions	Not published in the bullets — the product record carries 150 by 175 by 45 mm (1.77 in) and 1,102 g (38.9 oz), where the record for the 4 TB version of the same chassis carries 240 by 84 by 220 mm (8.66 in) at the same weight. The two cannot both be right

The questions that come up before an order

What is different from the 4 TB version?

One line. The seventh bullet reads 6 TB instead of 4 TB. The other nine bullets are word for word identical, so the price is the only thing left to compare.

Which of the two is better value?

At $230.99 against $192.99, the extra two terabytes cost $19.00 each, against $48.25 per terabyte on the smaller unit. If the capacity is useful, this is the cheaper storage.

Can one bay do RAID?

No. The first bullet claims it and the seventh states one drive bay. An array needs a second drive, and this chassis has nowhere to put one.
