Routers, switches and drives, read on their published figures
A class figure is arithmetic,
never a rate on a link.
Mesh systems and routers, access points and repeaters, switches and PoE switches, adapters and network cards, NAS enclosures and the drives that fill them, solid-state drives inside and out, UPS units — and the patch cables, keystone modules, panels, cabinets and enclosures ordered the following week. Compared on the lines that settle whether a part fits and how it behaves: what a class figure such as AX3000 adds together, which PoE class a unit asks for, the length and lane count a slot accepts, the difference between a stated capacity and the one your machine will display.

Every family covered here, end to end
Pick the job you are doing
20 families of hardware, 18 of cabling, enclosures and spares. Each hub below compares one of them, opening on a plain answer to “what should I actually buy?” — followed by the published line that family is most often bought against by mistake.
- Mesh routers Node count and the link between nodes decide coverage, never the headline number
- Wi-Fi routers A single router is judged on its band plan and its port speeds, not on a class number
- Wireless access points How the unit mounts and how it is powered come before its radio
- Wi-Fi repeaters A repeater trades throughput for reach, and the listing rarely says so
- Network switches Port count, port speed, and whether the fan ever stops
- PoE switches The per-port budget and the total budget are two different numbers
- PCIe network cards The slot, the lanes and the controller settle it before the port speed does
- USB network adapters The USB link behind the socket sets the ceiling of the Ethernet port
- Powerline adapters The stated rate belongs to the standard; the wiring of the building decides the rest
- Print servers Everything here hangs on whether your exact printer is on the published list
- KVM switches Resolution and refresh rate are one figure, and the switching method is the other
- Network cable testers Continuity, wire map and length are three different instruments in one word
- NAS enclosures Bay count, drive interface and the processor behind the applications
- NAS hard drives Recording method and stated workload rating are what separate these from desktop drives
- Internal hard drives Form factor, interface and rotational speed before the capacity
- External hard drives A mechanism, a bridge and a case, and buyers compare the wrong one of the three
- NVMe SSDs Form factor code, PCIe generation and lane count, before any speed figure
- SATA SSDs One interface caps every drive on the shelf at the same ceiling
- Portable SSDs The slowest link in the chain decides it, and it is rarely the drive
- UPS units Topology first, then the gap between the VA figure and the watt figure
- Patch cables Category, conductor construction and shielding, in that order
- Patch panels Port count, termination style, and the category the panel itself claims
- Network cabinets Usable internal depth is what turns a cabinet into a mistake
- Keystone modules The category on the module has to match the cable behind it
- RJ45 connectors Solid or stranded, shielded or not, and whether a load bar is in the packet
- Crimping tools The jaws decide what the tool can terminate, and the ratchet decides how well
- SFP modules Rate, medium, reach and the vendor coding the switch will accept
- Fibre patch cables Fibre type, connector and polarity, and only then the length
- NVMe enclosures The bridge chip and the host socket set the ceiling, not the drive inside
- Drive enclosures Drive size, interface, and whether it needs a mains adapter of its own
- Drive docks Bay count, what the slot accepts, and whether it clones without a computer
- USB flash drives Nearly every listing states a read figure and far fewer state a write figure
- Card readers The host link and the slot layout decide the reader
- UPS batteries The cell rating, the terminal width and the case size, all three or none
- Surge protectors Joule rating, clamping voltage, and a light that says the protection is still there
- Rack shelves Rack units, mounting depth, and how the shelf is held at the back
- Cable trunking The internal section decides how many cables actually fit inside
- Rack cooling fans Air moved against noise made, and the direction the panel pushes
How this site works
Three rules that hold every page together
-
Ordered on the published figures, never on the commission
What a product pays plays no part in where it sits. Where an unmanaged fanless switch is the right answer for a room people sit in, that is what the page says — and where a dearer unit earns its price only because its uplinks are 2.5GBASE-T rather than 1000BASE-T, the page says that instead, in those words.

The figure that decides, quoted as the maker wrote it
A PoE class named as 802.3af or 802.3at, a slot given as PCIe 4.0 with its lane count, a drive length written 2280, a cable category with its shielding code, a per-port budget kept apart from the total budget, a TBW rating kept apart from an MTBF statistic. These are the lines that settle whether a part fits and how long its maker specifies it for, and each one appears here in the unit its maker used, credited to the document it came from. A figure nobody published is recorded as missing rather than filled in.

Sent to the Amazon store you actually buy from
One button opens the same reference on the Amazon of the country you are browsing from, priced in the currency you pay in. Where a model has no offer there — and network hardware is stocked very unevenly from one market to the next — the page says so instead of pointing at an address that leads nowhere.
