<n​inoni:matrix.org> During Monero Gui installation when I chose the advance mode the node will be downloaded on my computer disc .

<n​inoni:matrix.org> Can I downloaded that on the external drive ? I do not have 250GB free space on my computer fot the node right now .

<o​frnxmr:xmr.mx> Change the storage location

<n​inoni:matrix.org> Could someone explain in few words what the node does ? What is it for ?

<n​inoni:matrix.org> I see. So there is no problem to run the node on external drive ?

<o​frnxmr:xmr.mx> It stores and verifies the history of the network and relays transsctions

<o​frnxmr:xmr.mx> No problem with it being external. An ssd is preferred as an hdd will be slow.

<n​inoni:matrix.org> I see. Thank you for explanation what the node is and what it does.

<n​inoni:matrix.org> I think on this time I need to use a HDD external drive until I find out how I can use the SSD internal drive. For now SSD has not enough space .

<g​ingeropolous:monero.social> you can also find the --prune option, whic will reduce the need from 250gb to almost 1/3rd

<g​ingeropolous:monero.social> there might be a checkbox setting somewhere in the GUI, but if not: monero.stackexchange.com/questions/…runing-in-the-gui-monero-wallet-gui

external drive is slower than internal and an HDD is very slow for downloading the blockchain due to it being poor with random I/O

see you in a month or 2 0_o

<n​inoni:matrix.org> Even with prune option there is not enough space on SSD drive.

<n​inoni:matrix.org> So the best is to have the node on an internal drive. I see. I need to find a solution then for my computer back up as the back up fills up my SSD drive right now .

an external SSD should not be too bad, depends on the interface

an HDD is bad for initial sync but will keep up once synced without issue

having an HDD on external gave me a visceral reaction :D

<n​inoni:matrix.org> I see. I need to find a solution for my computer back up then to get SSD internal drive free space.

<o​frnxmr:xmr.mx> Best is use an ssd, whether internal or external

<n​inoni:matrix.org> Could you please explain it to me in few words why is that ? What is the difference between SSD and HDD that SSD is better ,faster , more reliable then HDD ? Is it because HDD do not have the same mechanism which moves the disc itself ? I am just guessing ?

<o​frnxmr:xmr.mx> "HDD is very slow for downloading the blockchain due to it being poor with random I/O"

<o​frnxmr:xmr.mx> (Thx nioc)

<o​frnxmr:xmr.mx> aiui, lmdb (the database) does a lot of ramdom i/o

<n​inoni:matrix.org> Ok . Thanks . Now I know what you mean by random I/O :

<n​inoni:matrix.org> condusiv.com/sequential-io-always-o…ndom-io-on-hard-disk-drives-or-ssds

<n​inoni:matrix.org> Thank you .

<n​inoni:matrix.org> So actually I could have Externall SSD which will be almost the same speed and performance for Monero Gui Node as internal SSD drive ?

<n​inoni:matrix.org> Do I understand it right ?

not sure what the difference between an internal vs external SSD is but it will be significantly faster than a HDD
