[Lex Computer & Tech Group/LCTG] Vera Rubin Observatory Update

The compromise that I do on my PCs is to use an SSD for drive C and an HDD for the other drives. I use the C Drive only for installed programs and use HDDs for the "system defined" directories, such as Documents, Pictures, Desktop, Downloads, Music, Videos, Contacts, Saved Games, Favorites, Links and Searches Directories.

There is no better speed boost to a slow PC than booting off an SSD.

This also has the advantage that I can reinstall a fresh copy of Windows and my data is preserved. I would still have to reinstall all my programs but their data in still present.

Of course, this requires a PC that accepts multiple drives. Some PCs, such as all-in-one HPs, can be configures with an SSD and an HDD.

One aspect that hasn't received sufficient attention is the ability to record and manage vast amounts of data. I haven't checked recently, but I believe HDDs still outperform solid state memory in terms of cost and storage density. Although they are slower, that may not be the most important thing. I suspect this is also the case for AI LLMs.
HDDs are the unsung heroes of large data science and engineering, without which large data science would not be possible.
