You don't. If you have a hotswap chassis, or cables that support hotswap, you can hot-plug a drive. The difference is that in a hot plug cable, the ground pins stick out further than the 5v and 12v pins, so the ground lines make connection first. Once the drive is grounded, it can have power applied and not have an issue. All my sata 2 drives in my file server can be hot plugged at-will.

Does this hold true for external SATA drive too?

One other note that everyone has failed to mention is Bandwidth sharing.

 

A SATA port that's included on the mother board does not have bandwidth sharing with other SATA ports.

 

USB 2/3 when using a USB 2/3 hub does have bandwidth sharing. IE.... You have a USB 3.0 hub, and 4 devices connected to the hub. If all 4 devices are in use at the same time, then total USB 3.0 bandwidth is shared between the 4 devices. They are also not shared equally. It is possible that if 3 of the USB devices are "Slow" devices, and you have one faster device, more bandwidth will be devoted to the faster device.

 

Even with all that said. You still get total bandwidth sharing. Its not to big of an issue, if your plugging a keyboard or mouse into it. Although if you ever notice your mouse freezing, or keyboard lagging and its plugged into a USB hub, 9 out of 10 times, its due to bandwidth sharing. My real life is example is I had a USB 3.0 hub, 3 hard drives a key board and a mouse. I had some very heavy data transfer going on between the three drives and internal drives to the computer. Needless to say, but during the process my mouse lagged, and so did the keyboard. When all the data transfers completed. The keyboard/mouse lag vanished.

 

So keep that in mind When deciding.

P.S. 2 of the drives I was using that were plugged into the USB 3.0 hub were SSD drives that I was cloning.

      What? They aren't removing the disc drive and charging $800 for questionable performance upgrades that are better suited to a new generation console? How outrageous!

      Bummer it's only 1TB instead of 2. I had one of those - the "Halo Special Edition" OG Xbox. This looks like a cool update.

    • Google's NotebookLM gets some useful features you may have been waiting for

      By Aditya Tiwari · Posted

      Google's NotebookLM gets some useful features you may have been waiting for by Aditya Tiwari It's been three years since Google introduced its AI-powered note-taking and research app, NotebookLM. Just when Apple is about to kick off WWDC 2026, the search giant has announced a platter of new NotebookLM features that add agentic capabilities in chat and more advanced reasoning. For starters, NotebookLM now draws its fuel from Gemini 3.5 and Antigravity to improve accuracy and reliability. One of the things people have been asking for a long time is more transparency into the thinking steps. NotebookLM now shows expanded thinking steps in chat, providing better visibility into the thinking process. Google compared the upgraded NotebookLM with prior versions and found that it "achieved an average win rate of over 65% — a 15% point margin above parity — across our top five core evaluation dimensions," including accuracy & quality, multilingual support, large document analysis, document creation, and advanced research. It showed substantial improvements in analyzing large documents, achieving a 69.9% win rate. The system also delivered "exceptional performance" in advanced web research and source discovery with a 78.2% win rate. The AI research tool now generates outputs in more formats. You can give instructions to guide the outputs and download the generated files from the studio panel. Here are the newly supported formats: PNG and SVG for data visualizations and charts PDFs, docx, markdown, and text files for documents PNG, JPG, and GIF for images JSON and CSV for structured data XLSX for Microsoft Excel PPTX for Microsoft PowerPoint You can make edits after the outputs are generated. The feature is available globally; therefore, you can provide directions in one language and create outputs in another. Google said that it's also making it easier to get started with a project in NotebookLM. Instead of having a list of sources beforehand, you can even start with loose ideas, and NotebookLM can help build the repository of sources through the chat. For instance, you can find primary sources in other languages to get new perspectives or explore related works of an author. All of these new features are rolling out globally for those who can loosen up their pockets. They are available to users with Google AI Ultra and all Workspace business customers with AI Ultra access. Google has plans to expand them to more users in the future.
