Connectivity

The method of connecting a pocket with an installed drive to a computer, provided for in the design.

Note that this parameter is specified only in cases where the connection interface differs from the drive interface (see above). A similar feature is typical for all external models and docking stations (see "Type"): nowadays they most often use USB 3.2 gen1, less often — USB 2.0 or USB-C of one version or another (see below). In internal solutions, the drive connector rarely differs from the pocket connector, although there are exceptions.

It is also worth mentioning that in external models, the connection method is usually determined by the type of bundled cable; moreover, such a cable is often made removable, with the possibility of replacing it with a “cord” with a different type of plug.

As for specific connection methods, here are their main features:

— USB 2.0. USB is used to connect external peripherals, including pockets; this is the most popular modern interface of this purpose. And version 2.0 is the oldest USB standard in use today. The possibilities of such a connection are very limited — in particular, the power supply through the connector is 2.5 W, and the maximum data transfer rate does not exceed 480 Mbps. This is noticeably slower than even SATA 2 (3 Gbps), not to mention SATA 3 (6Gb/s); so in general this stan...dard is considered obsolete, and in pockets with this type of connection, the overall speed is limited just by the capabilities of USB 2.0. However, maintaining this interface is inexpensive; for simple tasks that are not associated with large volumes of information, it often turns out to be quite enough; in addition, USB 2.0 devices are fully compatible with newer USB ports. So nowadays you can still find pockets with this type of connection — these are basically the simplest and most inexpensive models.

— USB 3.2 gen1. Full size USB connector (not USB-C) compliant with version 3.2 gen1. This version (formerly known as USB 3.1 gen1 and USB 3.0) is the direct successor to USB 2.0, delivering up to 10x faster data transfer rates—up to 4.8Gbps—and more power. The mentioned speed is almost one-on-one with the capabilities of the popular SATA 3 internal interface; therefore, pockets with this type of connection are extremely common nowadays.

— USB-C 3.2 gen1. Connecting to a USB-C connector that complies with version 3.2 gen1. In terms of capabilities, this method is identical to the “normal” USB 3.2 gen1 described above, the difference lies only in the type of connector. USB-C is a relatively new standard used in both fixed and portable electronics. This connector is noticeably smaller than the standard USB A (slightly larger than microUSB), while it has a convenient double-sided design. However, specifically in computers and even laptops, USB-C ports are used much less frequently than full-sized USBs, so this option is relatively rare in pockets.

USB C 3.2 gen2. Connecting to a USB-C connector that complies with version 3.2 gen2. See above for more details on USB-C in general. And USB 3.2 gen2 (formerly known as 3.1 gen2 or simply 3.1) is the successor to 3.2 gen1, with even more advanced features: the maximum connection speed in this standard is 10 Gbps. On the other hand, for SATA drives, such speed is unnecessary, support for this version is quite expensive, and USB-C 3.2 gen2 connection ports are still relatively rare. Therefore, this option has not received distribution in pockets either: it is provided only in individual models for M.2 SSD with PCI-E connection, where the speed of the internal interface is already measured in tens of gigabits per second.

— PCI-E. Connect to a standard PCI-E slot on the motherboard. In other words, such pockets are connected to the computer in the same way as video adapters, sound cards, and other expansion cards. This design is used in select internal models for M.2 SSD drives; using such a pocket, you can connect a similar drive to a desktop PC even if the native M.2 ports on the motherboard are busy, unavailable, not suitable for connection (for example, they use the SATA interface, while the drive is made for PCI-E), or absent altogether.
Note that such pockets are usually compatible with M.2 PCI-E SSD modules without problems, but compatibility with M.2 SATA should be specified separately (although such functionality is also found). It is also worth mentioning that PCI-E slots and devices for them can have a different number of lines, and the general rule here is this: the number of lines in a slot on the motherboard must be no less than that of the connected board. However, in pockets with such a connection, usually less than 4 lines are provided, so they can be connected to PCI-E connectors starting from 4x.

— IDE. Outdated interface for connecting internal drives. It is extremely rare in modern pockets — in separate models designed to install modern or HDD / SSD in outdated computers without SATA and other relevant connectors.

Max. drive size

The maximum storage capacity supported by the pocket. In models with multiple disks/SSDs (see "Drive Slots"), this item indicates the largest total volume supported by the device; by dividing this capacity by the number of slots, you can determine the maximum allowable capacity of each individual drive.

The limitation on the maximum volume is relevant mainly for external models, including docking stations (see "Type"). This is due to the fact that fundamentally different interfaces are used for the drive and for connecting the pocket itself in such models (most often SATA and USB, respectively, see above for details). For the normal interaction of such interfaces, an electronic controller is required; and the larger the volume of the installed drive (s) — the higher the requirements for the performance of such a controller.

Note that, other things being equal, supporting large volumes is more expensive, and capacious drives themselves are not cheap. Therefore, when choosing according to this indicator, it is worth considering real needs, and not chasing the maximum numbers.
