Now there is that kind of big portable hard drive, how many gigabytes does it generally have, what i

Forehead. Landlord. All right.

Portable hard drives have much more storage space than USB flash drives.

And the USB flash drive is flash.

Portable hard drives are physical memory.

It's like the hard drive on your computer (actually inside the portable hard drive.

It's the kind of hard drive you have in a laptop).

Due to the large storage space.

Therefore, the speed of transferring data will also be much worse.

Usually.

The same brand of mobile hard disk or USB flash drive.

The larger the storage space.

The faster the data is transferred.

The largest USB flash drive should only be 10 G now.

Portable hard drives need to have hundreds of gigabytes

Or even 1 t (1t is about equal to 1000g).

2 t so.

Portable hard drives are used to store or transfer large amounts of data.

For example, some big games and so on.

And what about the USB flash drive. It is usually used to transfer some relatively small data.

hard disk words. Except for the fear of falling.

There shouldn't be anything else special.

Then there is it. It's just like ordinary electrical appliances.

I'm afraid of getting into the water or something.

I think the landlord should know about this...

I hope the landlord understands.

There are still words that I don't understand.

Just ask. I know the words.

will do their best. Forehead. Upstairs said 500g USB flash drive.

Really? Maybe I'm Martian again.

Yes, IBM's 40G mobile hard drive is estimated to be about 500 yuan.

Like a computer connection and a USB drive, the internal structure is different.

You can also right-click in the "My Computer" window: view the details, and the total size of each disk is the total.

Now there are a lot of mobile hard disks, and the capacity is also large, the difference between it and U is: U disk has a small capacity, but it is convenient, because it is small? Although the mobile hard capacity is large, the volume is also large, inconvenient, and there are many lines, which is the same as the hard disk in the computer!

To the hard disk capacity of your computer: Open My Computer, right-click all areas, properties, and you can see the capacity!

OK, that's it.

They are not stored in the same way.

A hard disk is a primary computer storage medium consisting of one or more discs made of aluminum or glass.

These discs are covered with ferromagnetic material. The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive.

U disk is a kind of flash memory, also called flash disk, USB disk, the biggest feature is: small, large storage capacity, cheap. It is one of the removable storage devices.

The hard disk is relatively large, the USB disk is relatively small (size), the unit capacity of the hard disk is much cheaper than the USB flash drive, the mainstream USB flash drive is about 1G, and the mainstream mobile hard disk is 160G.

Summary: Large capacity** cheap but more afraid of vibration than USB flash drive, size and weight are also larger, U disk is small and easy to carry but expensive capacity is also limited, hard disk can store a lot of things.

Hard disks have a large capacity and are relatively expensive. Slow down.

U disk, small capacity, relatively fast speed, cheaper.

In terms of volume, mobile hard disks are large, U disks are small, and mobile hard disks consume more power than U disks.

It's a big U disk, the difference is that the U disk can be dropped, and the mobile hard disk may be finished if it falls.

It is said that it is equivalent to a large USB flash drive, and if there is more knowledge, the disk on the computer can be stored on other computers at any time.

A new level of storage capacity, security, confidentiality, and more.

He is not even as good as the big USB flash drive in some aspects.

Merit; Portable hard drives have large storage and fast speeds.

Shortcoming; Fell to the ground and broke.

Merit; U dribbling is convenient and slow.

Shortcoming; Storage is inadequate.

The difference in material, the U disk uses flash memory, and the mobile hard disk uses a glass platter.

Essentially, mobile hard drives are easy to break... The USB flash drive is not easy to break and is easy to carry.

The other is a mobile hard disk is n USB flash drives...

USB flash drive access speed is faster than that of portable hard drives! And its.

USB flash drive is more convenient to carry!

You can see what you use them for first.,If you consume a lot of storage, buy a hard disk.,Just use some small things for the office.,Just use a USB flash drive.

USB flash drives and portable hard disks are not stored in the same way.

Mobile hard disk is essentially a hard disk, and the USB disk is essentially a flash memory EEPROM bar, and the mobile hard disk is relatively large, the USB disk is relatively small (size) The unit capacity of the mobile hard disk is much cheaper than the U disk, and the largest U disk is now only 2G, and the mobile hard disk is simply 40G or larger.

Summary: Large capacity** cheap, but more afraid of vibration than USB flash drives, the size and weight are also larger, and the U disk is small and easy to carry, but expensive and has limited capacity.

The minimum capacity of the mobile hard disk is generally 20g, you can have a lot of things, it can be partitioned, the U disk is only used more in the initial stage of using the computer, you can save some small files, such as word, even PowerPoint may not be able to save, as for **, you can only save some small ones, but you can store quite a lot of things with the hard disk, the hard disk in our computer is generally 80 to 120g, and the mobile hard disk can also reach this extent if it is large, so it is very applicable, Now the price is not too high, the area is smaller, 40G mobile hard disk is about six or seven hundred, the kind that is inconvenient to carry, about six hundred can be bought 80g.

Portable hard drives have a large capacity and are relatively expensive. Slow down.

U disk, small capacity, relatively fast speed, cheaper.

For example, 40G, mobile hard disk is about 500 points.

And more than 500 RMB, you can only buy less than 1 G USB flash drive.

In terms of volume, mobile hard disks are large, U disks are small, and mobile hard disks consume more power than U disks.

A portable hard drive is a portable hard drive.

A few more chips than normal.

The USB flash drive is just a memory, at least it doesn't have to be rotated.

Portable hard drives (60---250G) usually have a much larger capacity than USB flash drives (128M---1G).

The transfer of mobile hard disk is more troublesome, and the USB flash drive is faster.

If you're engaged in design, it's good to use a USB flash drive.

I use USB flash drives for school design.

It's convenient

U disk is flash memory, generally speaking, the capacity is relatively small, now it is about 2G, 4G, 8G, etc., **Cheap, easy to carry.

Mobile hard disk capacity is large, 160g, 250g, 320g, 500g, etc., **slightly expensive, easy to carry without U disk.

It depends on your personal preferences.

The memory of the USB flash drive is smaller. Convenient to bring .........The portable hard drive has a large memory and is as large as an old-fashioned word translator.

1.The size is not the same.

The disk is solid-state, and the general portable hard disk is dynamic.

Due to too much content, it can't be published here, you can see the link below for details:

What is a portable hard disk?

What is a USB flash drive?

What is flash memory.

The function of the mobile hard disk is the same, but the data stored is somewhat different, and the mobile hard disk is safer than the U disk (referring to the storage of data). Be sure to keep your hard drive clean when it comes to use.

Moreover, the speed of mobile hard disks is mostly at 5400 rpm, so the speed is much faster than that of USB flash drives. If it is only used to store your own data, you can buy a U disk, mainly because the storage medium used is different, the U disk uses a flash chip, and the mobile hard disk uses a hard disk as a memory. In terms of volume, the U disk is smaller, and the mobile hard disk is larger; USB flash drives are relatively better than portable hard disks.

You can buy SSDs! Large capacity, faster than USB drives and hard disks! Very expensive...

If you just save data, it is recommended to use a USB drive if you need to back up a large amount of data. It is recommended to have a hard disk, in fact, you can buy a mobile hard disk for one or two or three hundred yuan, and then buy a 4 or 8G USB disk for dozens of dollars!

I should not have a portable hard disk without 2G. A 2G USB flash drive should be more than 100 points.

A 2G USB flash drive is better. **Approximately $100.
