GRAUGEAR single-slot M.2 dock for NVMe and SATA, RTL9210B, 2230 to 22110, active fan

The one dock in this hub with no SATA bay at all: a single M.2 slot with active cooling, the only listing anywhere in this lot to accept a 22110 module.

GRAUGEAR single-slot M.2 dock for NVMe and SATA, RTL9210B, 2230 to 22110, active fan

The one dock in this hub with no SATA bay at all: a single M.2 slot with active cooling, the only listing anywhere in this lot to accept a 22110 module.

Bay count
One — a single M.2 slot. No 2.5-inch or 3.5-inch bay exists, which makes it the only dock on this shelf that will not take a conventional drive at all
Supported drive sizes
M.2 modules only — the third bullet names all common M.2 formats from 2230 to 2280 and adds 22110, which no other listing in this lot mentions
Supported drive interfaces
NVMe M.2 SSDs in M-key and SATA NGFF SSDs in M+B key — stated in the second bullet, which credits the RTL9210B chipset with the dual support
Solid-state slot support
The whole device is one — the M.2 slot is the only position, and it accepts both the NVMe and the SATA protocol. Every other dock on this shelf has SATA bays and, in one case, an M.2 slot alongside them
Offline cloning
Not published on the listing — no clone button and no copy function is named in any of the five bullets. With a single slot there is no second drive to copy to
Interface standard
USB with the RTL9210B chipset — stated in the second bullet. The USB generation is not named in words; the first bullet gives the rate instead
Stated link rate
Up to 10 Gbit/s for a PCIe 3.0 x2 NVMe SSD, and up to 6 Gbit/s for a SATA SSD — both stated in the first bullet, which is the only listing in this lot to publish a separate figure for each protocol
Connector type
Not published on the listing — no Type-C, Type-A or cable is named in any bullet
UASP support
Not published on the listing — UASP is not named anywhere. Fourteen of the nineteen listings in this lot publish it
Power supply
Not published on the listing — no adapter, voltage or current is named. An M.2 module and a small fan are a modest load, and the page does not say whether the dock runs from the lead
Per-bay controls
Not published on the listing — no switch and no indicator is named. The third bullet supplies an acrylic cylinder for storing and protecting an M.2 drive, which is a case rather than a control
Amazon reference

  • A fan inside, which nothing else in this lot has
  • Accepts 22110 modules, the only listing here to name that length
  • No SATA bay at all, so a 2.5-inch or 3.5-inch drive will not go near it

Best for: A desk where M.2 modules are read and imaged one after another and the drive has to stay cool while it happens.

On the listing

An M.2 SSD docking station for M.2 NVMe PCIe and NGFF SATA drives, with transfers of up to 10 Gbit/s for a PCIe 3.0 x2 NVMe SSD and support for SATA SSDs at up to 6 Gbit/s; an RTL9210B chipset supporting NVMe M.2 SSDs in M-key and SATA NGFF SSDs in M+B key; a tool-free installation accepting all common M.2 formats from 2230 to 2280 and additionally 22110, with an acrylic cylinder supplied for storing and protecting an M.2 drive; an integrated quiet fan for heat dissipation, said to reduce thermal throttling and keep performance stable through long transfers and heavy load; and a general statement of quality from the maker.

The only fan in this lot

Nineteen listings. One of them moves air.

The fourth bullet names an integrated quiet fan and names what it is for: reducing thermal throttling, the behaviour where a drive that has become too hot slows itself down until it cools.

That is the central problem of the M.2 shelf of this site, and every enclosure there answers it passively — aluminium, sometimes a thermal pad, sometimes nothing but the word aluminium. Passive cooling works until the transfer is long, and then it does not.

A dock is open rather than sealed, so a fan is easy to fit and easy to justify. For anybody who spends time copying large volumes off M.2 modules, this is the device on which the rate should hold rather than sag.

No SATA bay, and that is deliberate

Six docks on this shelf take 2.5-inch and 3.5-inch drives. This one takes neither.

It is an M.2 instrument: one slot, two protocols, five lengths. A conventional hard disc has nowhere to go on it.

That makes it a different purchase from everything beside it, and one worth being clear about before ordering. If the drawer of drives waiting to be read is full of laptop discs, this is not the tool. If it is full of M.2 modules pulled from machines being retired, nothing else on this shelf will read them properly.

Twenty-two-one-ten

The third bullet names the M.2 lengths and includes 22110.

Every other M.2 listing in this lot stops at 2280. A 110 mm module — the kind that comes out of servers and some workstations — has effectively nowhere to be read, and this is the one product here that names it.

It is a small constituency and it is completely unserved otherwise.

A rate for each protocol

The first bullet gives 10 Gbit/s for a PCIe 3.0 x2 NVMe drive and 6 Gbit/s for a SATA one.

That is the only place in this lot where a listing separates the two figures instead of printing one headline number and letting the reader assume it applies to everything. It is also a more careful claim than most: naming PCIe 3.0 x2 says which class of drive the ten gigabits assumes, which is a step towards the condition that most rate figures on this shelf never carry.

What is missing

No clone function, which follows from having one slot. No connector named. No power arrangement named. No UASP.

The connector is the awkward one. Five bullets describe the chipset, the formats, the cooling and the storage cylinder, and none says what plugs into the computer or what cable arrives.

Before ordering

Be clear that this reads M.2 modules and nothing else. Ask what socket and what cable, because neither is on the page. And if the drives are 22110, this is the only listing in this lot that will take them.
