Comparison Ugreen UG-60718 vs BASEUS Metal Gleam Series 8-in-1 Multifunctional Type-C Hub

— Card Reader. Devices designed primarily for reading various types of memory cards. They may have USB ports (see "USB inputs"), but usually less than one (very rarely two). There are both external and internal (see "Purpose").

— USB hub. He's a "splitter". A variety of peripheral devices designed to increase the number of working USB ports in the system. The hub has several own USB inputs (usually at least 4), and only one such port is used to connect it to a computer. Thus, by connecting, for example, a 4-port hub to a computer, you will get 4 instead of one USB port. Such devices can be useful for those who have to use many USB devices at the same time, as well as for owners of compact laptops where there are few standard connectors. However, keep in mind that the power of one port may not be enough to power all the peripherals connected through the hub, for more details see "Connecting the power supply". Models of this type are only external(see "Purpose").

— Card reader / USB hub. External (see "Purpose") devices that combine the functionality of the two types described above: they have both slots for memory cards and USB ports, which allows them to be used as both card readers and hubs. However, it is worth noting that USB ports in such models are usually fewer than in full-featured hubs, and some even h...ave only 1 USB input.

The number of USB Type C ports for connecting peripherals provided in the design of the hub (or card reader with the hub function — see "Type").

The port itself is small — only slightly larger than microUSB — and has a reversible design, thanks to which the plug can be inserted in either direction. That is why he has exacted respect and is actively replacing the classic USB port.

Despite its small size, USB Type C is used both in portable technology and in desktop PCs and peripherals for them. However, there are still few such devices available; because of this, hubs usually provide 1 USB-C port or 2 type C inputs.

The presence of a micro USB port for connecting peripheral devices in the design of the hub (or a card reader with a hub function — see "Type").

The main scope of microUSB is portable equipment — smartphones, tablets, etc. Accordingly, it makes sense to purchase a hub with such a connector if you want to connect peripherals that were originally designed for mobile gadgets to a PC — for example, flash drives for smartphones with USB OTG function. Usually there is only one microUSB connector — more is simply not required.

HDMI is the most popular of today's multimedia digital interfaces. It is specifically designed for HD content and delivers high-definition video and multi-channel audio over a single cable. HDMI outputs are found mainly in hubs connected via USB Type C and compatible with the Thunderbolt interface (see "Connection"). Actually, to use HDMI, you will need to connect the device to the Thunderbolt v3 connector — "pure" USB Type C does not provide video transmission. This feature can be useful if the external screen is designed for HDMI connection, but there are no such connectors in the PC or laptop itself, they are busy or unavailable for another reason. At the same time, HDMI can be a different version, which affects the throughput. So to transfer video in 4K at 60 fps, you must have HDMI v 2.0 or 2.1.

— SD(from Secure Digital). One of the most common modern memory card standards, widely used in photo and video equipment, laptops, tablets, etc. The media has a size of 32x24x2.1 mm. A design feature is mechanical write protection in the form of a slider (however, its correct operation depends on the functions of the card reader, and not on the card itself). Support password protection and DRM technology. To date, there are three generations of cards of this standard: the original SD (up to 4 GB), SD HC (up to 32 GB) and SD XC (theoretically — up to 2 TB). Their physical size is identical, and the card readers support earlier generations, except for the main one. So, the device under SD HC will “understand” the original SD, and the reader under SD XC reads all three generations. At the same time, a "later" card will not be able to be read correctly by an "earlier" card reader.

— miniSD. Smaller version of SD cards (see above). It is identical to them in almost everything, except for the size (22x20x1.4) and write protection, due to which it can also be read in SD-card readers when using a special adapter.

— microSD. Another smaller version of the SD standard, 15x11x1 mm in size. Almost completely identical to the original, except for the dimensions and write protection. Due to its compactness, it has become widespread in portable technology, espe...cially mobile phones. It can also be used in SD card readers when using an adapter, and in some models even without it. — CompactFlash. This standard appeared one of the first and has survived to this day in a slightly modified form due to its good capacity (up to 512 GB) and high write speed — which is especially important in professional digital photography and video filming, where these cards are still quite widely used. The disadvantage is significant dimensions: 42x36 mm with a thickness of 5 mm (CompactFlash Type I) or 3.3 mm (CompactFlash Type II). The compatibility of both types in fact is directly related to the size: the Type II card simply won't fit in the Type I reader, but vice versa is quite possible. In addition, Type I and Type II differ in speed.

— XQD. A format developed by the CompactFlash Association as a potential replacement for CompactFlash and intended for devices with high requirements for read and write speeds. Actually, the data exchange speed, depending on the version, can reach 1 GB / s in the original XQD and 2 GB / s in cards supporting the CFexpress standard, with the prospect of further increase to 8 GB / s and even higher. At the same time, the cards themselves turned out to be smaller than СompactFlash, although they are still quite large — 39 x 30 mm with a thickness of 3.8 mm.

— MemoryStick. Sony's proprietary memory card format is used primarily in its devices, such as camcorders and handheld consoles. Such cards have a size of 50x21.5x2.8 mm (original version) or 31x20x1.6 (various Duo modifications), and the volume can reach 32 GB. Although cards are produced not only by Sony, the standard is officially closed, and therefore only cards of the original production can be guaranteed to comply with it.

— Memory Stick Micro (M2). A smaller version of Memory Stick cards (see above), have dimensions of 15x12.5x1.2 mm and a capacity of up to 32 GB. Compatible with readers for original Memory Stick using special adapters.

— xD-Picture. A specialized format jointly developed by Olympus and Fujifilm for their own digital cameras. They are distinguished by the absence of their own memory controller, which, on the one hand, ensures compactness and reliability, on the other hand, reduces performance. In addition, according to Olympus, using this card allows you to work with some of the camera's own effects. The theoretical volume of such cards is up to 8 GB. Another disadvantage is their high price. Due to this, xD-Picture is used quite rarely, and even manufacturers themselves transfer their products to other standards.

— MMC. Universal memory cards, similar in size to SD — up to the point that they are compatible with SD readers, and on some modern devices (cameras, camcorders, laptops ...) "SD / MMC" is directly indicated. At the same time, SD cards simply won't fit in MMC card readers. MMCs have low power consumption, but are expensive and not very fast in operation. Their maximum volume is 4 GB.

— MMC micro. A smaller version of MMC standard cards (see above) — they have dimensions of 12x14x1.1 mm, otherwise they are almost identical.

— cfexpress. Incredibly fast high-capacity drives with an eye for long continuous recording in intensive mode. They are the best suited for shooting video in 4K resolution and higher with a frame rate of 120 fps. So far, they are not so common in photo and video equipment. There are two types of CFexpress drives: Type A with dimensions of 20x28x2.8 mm and Type B with dimensions of 38.5x29.8x3.8 mm.

— SIM cards. Ability to use a card reader to work with SIM-cards used in mobile phones. In modern mobile phones, the SIM card is responsible not only for the number on the network — it can store a lot of different information, such as contacts, messages, settings profiles, etc.; as a result, the loss of a SIM due to loss or theft can turn into serious difficulties. The SIM card reader is designed primarily for such situations: with its help, you can save a backup copy of the data from the SIM card on a computer or external media, and later, if necessary, restore them without any problems.

The technology allows you to work at higher voltage, thereby increasing the transmitted power. USB hubs with Power Dlivery can not only charge smartphones faster, but also power more power-hungry devices, such as laptops.

A special compartment on the case of the card reader or hub (see "Type"), in which the USB cable is placed during non-working hours. Such models are compact and easy to transport due to the fact that the wire, which tends to get confused and interfere, is hidden inside the device. For objective reasons, only devices with an external connection can have a cable compartment(see "Intended use").

Light indicator, indicating that data is currently being exchanged between the memory card and the computer to which the card reader is connected. This allows you to avoid disconnecting the card reader during operation, which is fraught not only with data loss, but even damage to the device.
