Read the page and right after we’re gonna do some brain activity by clicking the link below. Today’s lecture is about computer’s External Memory. If you are not satisfied with the RAM, you can replace it with a better one.Hello there! Welcome to my Site. Of course, some people also think that external RAM is unnecessary, because the RAM in laptop is usually replaceable. At present, there is no external port reaching these speeds. However, some DDR3 RAM can be up to about 15 GB/s and some DDR4 RAM can be up to 25 GB/s. Nowadays, we usually use DDR3 or DDR4 RAM. These interfaces are incompatible with USB or Thunderbolt port.īesides, although the data transfer speed of USB 3.0 can be up to 5Gbps (about 600MB/s), and Thunderbolt 3 interface's speed can be up to 40Gbps (5GB/s), these speeds can't match that of RAM. However, RAM should use DDR, DDR2, DDR3, or DDR4 interface. This is very inconvenient.Īs we all know, nowadays, common external ports include USB port and Thunderbolt port. There is no method that can be used to deliver power supply to external RAM, except that you use a chassis like eGPU box. Read More Why Is the External RAM for Laptop Impossible Now?Īccording to the above content, we can know that the external RAM for laptop is impossible now for the following reasons: After all, RAM's speed is much higher than hard drive's, and therefore it will consume more power. However, there is no such a power delivery protocol that can supply enough power to external RAM. With this protocol, you can use the USB or Thunderbolt ports to supply power to the external hard drive. The power delivered can reach up to 100W. It can increase power transmission through USB cables and connectors to expand the power supply capability of the USB cable bus. This protocol is one of the current mainstream fast charging protocols. One of the reasons is the USB PD (Power Delivery) Protocol. To connect an external hard drive to a laptop, you just need a cable. These ports can be used to connect external hard drive. In general, the laptop will come with one or more external ports like USB ports, Thunderbolt (PCI-E) ports, etc. How Is an External Hard Drive Added to Laptop? To figure out this problem, we should first know how the external hard drive or external GPU is added to the laptop. Some people may wonder whether it is possible to have external RAM for laptop. Nowadays, we have external hard drive and external GPU. Why Is the External RAM for Laptop Impossible Now?.
