Hello everyone, today we are going to learn about the SSD on Apple mainboard

2

00:00:07,233 --> 00:00:09,600

SSD is a solid state disk

3

00:00:10,266 --> 00:00:14,300

It is a hard disk made of solid state electronic memory chip array,

4

00:00:15,900 --> 00:00:19,600

consisting of a control unit and a memory unit

5

00:00:22,833 --> 00:00:26,766

There are two types of solid-state drives in today's Apple laptop

6

00:00:27,266 --> 00:00:31,533

One is pluggable, like this one, with a hard drive slot

7

00:00:32,766 --> 00:00:36,533

This slot is different from the slot on a regular PC

8

00:00:37,766 --> 00:00:42,233

It is neither an M.2 nor a Mini PCIe slot,

9

00:00:46,166 --> 00:00:48,366

which is an Apple-only interface

10

00:00:51,266 --> 00:00:55,100

So Apple's solid-state drives don't work on regular PCs

11

00:00:57,133 --> 00:00:59,066

The second is the onboard hard drive,

12

00:00:59,300 --> 00:01:04,200

that is, the memory chip of the hard drive is directly welded to the mainboard

13

00:01:05,933 --> 00:01:08,133

For these two types of hard disks,

14

00:01:08,533 --> 00:01:12,400

it is easier to replace and upgrade a hard disk that is pluggable

15

00:01:15,200 --> 00:01:19,066

However, it is difficult to replace the onboard hard disk,

16

00:01:19,766 --> 00:01:22,500

which requires certain welding ability

17

00:01:24,966 --> 00:01:28,166

For example, like this solid-state drive

18

00:01:31,000 --> 00:01:34,933

On the hard disk, the largest chip is the hard disk master,

19

00:01:36,100 --> 00:01:39,733

which is managed by the CPU through the PCIE bus

20

00:01:43,300 --> 00:01:46,966

A damaged SSD causes unrecoverable data loss

21

00:01:48,433 --> 00:01:50,300

The data is stored in the chip,

22

00:01:51,300 --> 00:01:56,733

and once the chip is damaged, the data is devastating and cannot be recovered

23

00:02:00,766 --> 00:02:04,166

Okay, so that's an introduction to solid state drives
