The article for today.

While I was looking at Serial ATA comparison with other buses, I noted the following table in the form of the textual rows.


    Memory type; internal devices; external devices
    HDD, hard disk drive, hard disk, hard drive, fixed disk; internal devices; external devices
    SSD, solid-state drive, solid-state storage device, solid-state device, solid-state disk; internal devices; external devices
    flash drive, flash memory-based CompactFlash (CF), card (including CFast card), XQD card, Memory Stick (MS), MultiMediaCard (MMC), Secure Digital card (SD, SDHC, SDXC), SmartMedia card (SM), Solid-state drive, SSD, using flash memory (a few SSDs use DRAM or MRAM), USB flash drive (UFD), xD-Picture Card (xD); ; external devices
    DDR SDRAM, Double Data Rate Synchronous Dynamic Random-Access Memory; internal devices; 
    GDDR SDRAM, Graphics DDR SDRAM; internal devices; external devices
    central processing unit(CPU) cache; internal devices; 
    tensor processing unit(TPU) memory; internal devices;

I mean some devices are only internally installable and some devices are only externally connectable.

There are some devices which are both internally installable and externally connectable.

I mean I did not find big external central processing units (CPUs) with changeable CPU caches as memories for other devices. On the contrary some central processing units (CPUs) are in the order of nanometers in computer devices.

Moreover some solid-state devices(SSDs) and hard drive devices(HDDs) have hot pluggable capabitity meaning that they are connectable and disconnectable with certain conditions while computer is active by processing those events and handling those device connections with no restarts. I did not find whether some central processing units (CPUs), CPU caches and double data rate synchronous dynamic random-access memories have such hot pluggable capabitity.

So that I as a user would extend the internal memories with external ones similar to solid-state device(SSD) and hard drive device(HDDs) process.

Probably such option is in direct connection with the buses, boards where the memories are installable and connectable and their capabilities to support such connections.

Some of the memories are connectable via cords, cables, wires. Some of the memories are connectable via solid connectors and adaptors. Some of the memories are connectable wirelessly, cordlessly, cablelessly.

При доступній наявності можливості для дампа це особливість.

On available dumpability it is a feature.
