Differences between Hard disks and SSDs Explained,Advantages of Hard disksDisadvantages of hard disks

There are two types of hard disks: HDD and SSD. HDD uses mechanical parts to store data. SSD uses integrated circuits to store data. SSD drives are costly but provide higher data transfer speeds.

HDD

HDD stands for Hard Disk Drive. A hard disk contains spinning platters and a moving needle. Platters are circular disks made of a nonmagnetic material such as aluminum alloy, glass, or ceramic. They are coated with a thin layer of magnetic material on both sides that is used to store data.

The moving needle is called the head. It is used to perform read and write operations on platters. During this operation, the platters rotate at tremendous speed. The speed is measured in RPM. More RPM means more speed and cost.



Advantages of Hard disks

  • Hard disks are much cheaper than SSDs. At the price of a 256 GB SSD, you can buy a 1 TB HDD.
  • Hard disks are available in much bigger sizes than SSDs. You can easily buy an 8TB or a 16 TB hard disk from any local retailer or online store.
  • Hard disks contain mechanical parts that you can replace at any repair shop. For example, if a hard disk's head is damaged, you do not need to change the entire hard disk. You can replace only the head.
  • Hard disks provide a slower data transfer speed compared to SSDs.

Disadvantages of hard disks

  • Since hard disks use rotatory platters to save data, they make noise during reading and writing operations.
  • They are vulnerable to shock and sudden movement, which makes them a poor choice for laptops.
  • Since they contain moving parts, they are prone to damage.
  • SSD:

    SSD stands for Solid State Drive. SSDs use integrated circuits to store data. They do not contain any moving or magnetic parts. They use ICs that are fixed on PCBs. It makes them more durable, faster, and less prone to damage and corruption.

    There are two types of SSD: SATA SSD and NVme SSD. SATA SSD uses a SATA interface. NVMe SSD uses an NVMe interface. The SATA interface uses a SATA cable to connect the SSD drive to the motherboard. NVMe interfaces are directly mounted on the motherboard. You can call them NVMe slots. You need to attach NVMe SSD disks directly to these slots.

  • Advantages of SSD

    • SSDs provide much higher data transfer speeds than HDDs.
    • Since they do not contain any moving or magnetic parts, they are less prone to damage.
    • They are more secure than the traditional HDDs.

    Disadvantages of SSD

    • They are more expensive than HDDs.
    • Bigger size SSDs are not easily available. You have to purchase them directly from manufacturers or distributors.
    • Since it does not contain any repairable parts, you have to replace the entire disk if it is damaged.

Embedding Audio Files from Google Drive into HTML,Get the Streaming Link,Convert to a streaming link

 Initially I had planned to create a Sound Cloud account to host the audio. Sound Cloud isn't really used for this sort of big brain music (sarcasm), but it's a great place to put your audio files where they're easily accessible. It looks like Sound Cloud was having some kind of authentication issue at the time and I was unable to create my account. My second plan also fell through, as it seems you can't host audio files for streaming on cloud Drive. Yes, I'm a shameless Apple user. No, it doesn't always work out for me.

In the end, I decided the best proxy solution would be to host the files on Google Drive. After some digging through Stack Overflow, I found the magic sauce to get embedded audio files.

Upload Your Files

You need to get your files into Google Drive. You'll need to upload all the codecs you may want users to be able to play.


The contents of my Google Drive after uploading some audio files.

Set Up Sharing

For each audio file, you'll want to turn on "anyone with a link" access. Right-click on the file and select "Get link".


Then click the dropdown shown and select "Anyone with a link".

Get the Streaming Link

This one is the annoying one. In the above image, click the "Copy link" button to copy the link to your clipboard, and then put it in a text file. Now take a look at that link (yes, I'm comfortable with you seeing a real link):

https://drive.google.com/file/d/166jxMcfmhUAevwj7QGz5HizLJ-cRj73T/view?usp=sharing

You'll see the link includes some kind of file identifier in it. In the link here, the format is: https://drive.google.com/file/d/<THIS_IS_THE_ID>/view?usp=sharing. This link is not currently streamable, but with the id we can create the link that is.

Convert to a streaming link

Take your existing link:

https://drive.google.com/file/d/<THIS_IS_THE_ID>/view?usp=sharing

And change up everything but the ID:

https://docs.google.com/uc?export=download&id=<THIS_IS_THE_ID>

You now have a streamable link!

Add Your Audio

You now have all the tools necessary to craft your embedded audio player. All modern browsers support the <audio> HTML tag, which gives you a player without having to create an iframe or anything else more complicated. Now, inside the HTML of your site, put the following code block (remember to substitute the id of the file in Google Drive):

<audio controls>

    <source src="https://docs.google.com/uc?export=download&id=<THIS_IS_THE_ID>" />

    <p>Your browser doesn't support the audio HTML tag.</p>

</audio>

1234

What will this do? It'll create a simple audio-playing interface for the user, pointed at your audio file in Google Drive. If the user's browser doesn't support the <audio> tag, it'll instead display the text in the <p> tag. I found the Apple documentation website the most useful for understanding how the tag works.

You should now have a working audio player on your website!


I performed the above steps 3 times to get 3 different audio players.

Advanced Audio

It turns out not every browser can support every audio format. The format you record in is not necessarily a format that your user's browser can play.

From some very brief digging, there seem to be 3 basic categories of web browser

1.      Supports AAC, MP3, and MP4 audio

2.      Supports audio, but probably only WAV files

3.      Doesn't play audio files

We don't actually care about the last category, because they'll figure it out on their own. And the first category is very, very small. All the mainstream browsers on mainstream operating systems fall into the first category.

So while you may see that I have multiple encodings of the same audio file in my images above, I really only have to attach one to my post to get the most traction with my users: the m4a file (which is an audio-only MP4 file).

But if you think you may have some nonstandard users on your site, you may want to encode your audio in a few other codecs. Ogg Vorbis and WAV files should typically capture all the users out there.

Working with multiple formats

If you do want to give your users a choice of audio format, you can encode that into your <audio> tag in the HTML.

<audio controls>

    <source src="<MY_OGG_FILE>" type="audio/ogg" />

    <source src="<MY_MP4_FILE>" type="audio/mpeg" />

    <source src="<MY_WAV_FILE>" type="audio/wav" />

    <p>Oops, something went wrong</p>

</audio>

123456

The browser will go through the list of audio sources in order and find the first one that it thinks it can play. If I load up the page in Safari, it'll see the type="audio/ogg" in the first source and know to not even try to download it. But when it encounters the type="audio/mpeg" source, it'll try to load that.

Generally you should keep your largest files the furthest down the list: your users will appreciate it if they don't have to download massive files to play your audio.

Transcoding audio

To get your audio into different formats, you'll need to download a program to do the conversions for you. I'm using MacOS, but I've been using freac for my transcoding needs even though it looks like a horrific early-2000s Windows program. I think the program is pretty self-explanatory, and it should give you the ability to pretty quickly create new files in different formats.

Recycle Bin Tricks and Tips for Windows 11/10 :Restore deleted items from Recycle Bin

The Recycle Bin in Windows! It’s there; we need it, but we hardly ever notice it. Some of us don’t even empty it, letting Windows do the job once it starts overflowing. Well, let’s change that, and let’s take a closer look at it today! Let’s see how it works and how we can get the best out of it in Windows 11/10.

Windows Recycle Bin Tricks and Tips

The Recycle Bin is just that! It lets you recycle deleted items. Once you delete any file or folder from the Windows File Explorer, it is moved and placed into this bin. It is not deleted as such.



To delete an item, you right-click on it and select Delete. This will move the file or folder to the Recycle Bin. If you press the Shift key and Delete, then the item will not be moved into the Recycle Bin. It will be directly deleted permanently.
