In computer networks, jumbo frames refer to Ethernet frames whose payload exceeds the limit of 1500 Bytes by the IEEE 802.3 standard, and are specifically designed for Gigabit Ethernet. Generally, the segment from 1500Byte to 9000Byte is called: jumbo frames, and then from 9000Byte to 64000Byte is called Super jumbo frames. Jumbo frames improve data transmission efficiency by sending a bigger frame of data instead of the standard one. The standard data frame has 1500 MTU size and the jumbo frame is typically set at 9000 MTU value size when enabled. Each manufacturer has different settings. For example, Ankmax UC31G2 USB 3.1 to 2.5GbE adapter has 4088Bytes, 9014Bytes, 16128Bytes and so on.Jumbo frame improves data transmission in two ways. First each frames sent have “overheads” or information regarding those frame. By sending out a jumbo frame instead of standard, you end up sending out more data with the same amount of overhead. The second way is that by sending a bigger amount o...
M.2 not only supports SATA, but also PCIe (Peripheral Component Interconnect Express), although not at the same time in a given M.2 SSD. It even supports USB 3.0, Bluetooth, Wi-Fi and Near-Field Communication (NFC) in certain configurations. Upon closer examination of an M.2 module, users may notice that there are notches, or keys, where the connector pins are located, yielding asymmetrical pin configurations. These determine which interface the M.2 module uses and the bus (PCIe, USB 3.0, etc.) that it can connect to. It’s also a design that prevents slotting an M.2 card into an incompatible interface or placing it in a reverse configuration. M.2 SSDs are capable of attaining high data transfer speeds, but it all hinges on the type of storage interface used. A SATA-based M.2 SSD is limited by SATA’s maximum limit of 600 MB/s (megabytes per second). An M.2 SSD that supports PCIe enables it to use NVMe (Non-Volatile Memory Express), a low-latency host controller interface specification t...
