What aspects of performance do you pay attention to when buying a mobile hard drive?

I think the first is the brands, like Seagate, Western Digital, Hitachi. Seagate focuses on performance, although it is expensive, but it is really good. The characteristics of Western Digital are not too prominent, and they belong to the comprehensive type.

Hitachi's main focus is close to the people, cheap, but it is not necessarily easy to use, and many people have used it and reflected well. Choosing a good brand can save you a lot less things.

The second is the interface, which is an inevitable trend.

And then there's the capacity!

Computer City. Most of them are fakes. Anyway, it's all fake, the quality is not necessarily bad, it's better to spend 200-300 to buy those so-called brand goods.

It is recommended to directly take the HDTUNE software (Baidu is everywhere) and run 1 time. Look at 1 time for the core and motor of the coil.

Western Digital (WD) has the best core. This is followed by Samsung and Seagate, Hitachi.

I said well, mainly in terms of whether the core is a parallel import. Western Digital has fewer parallel imports.

The motor motor time is less than 100 hours, and it should be a new platter. That's it.

hdtune sweeps 1 bad sector. Quickly scan 1 time. Slow sweep 1 time. If the merchant allows you to run hdtune scan. No problem, just buy it and take it home.

Take good care of yourself, and you'll be fine.

Look at the brand, but I don't recommend Hitachi, I just use Hitachi's after-sales super garbage! I'm still arguing with him! It's okay to use Seagate's.

Summary. The advantages of portable hard drives are:

1.Convenient for the pure world, especially when there are large-capacity storage requirements, it is not necessary to connect to the computer, I do only a mobile hard disk on the router, ** very convenient. It is also convenient to share resources in the mountains.

It can be used for emergencies and some system maintenance, and there are many PEs that can be directly placed in the hard disk, and the system is very easy to use.

Save space on your computer.

Carry it directly when you use it, reducing the weight of the computer.

As for the two models you mentioned above, the parameters are about the same.

The more discs, the worse because they consume energy and thicken or add weight to the entire drive.

Avoid heavy impacts or drops from heights on daily portable hard drives. Just pay attention to these two aspects.

When choosing a mobile hard disk, you need to look at the parameters and functions of the mobile hard disk, some of the more distinctive functions may be slightly more expensive, and the choice of mobile hard disk is divided into original and assembly, the original is that some manufacturers have installed the mobile hard disk and mobile hard disk box, and the original is warranted. Assembling is to buy a mobile hard disk + mobile hard disk enclosure by yourself, and then ask the master to help you install it at the place where it is sold, or you can install it yourself if you have strong do-it-yourself ability. The original one is a bit more expensive than the assembled one.

But the original ones are guaranteed by quality. The better brands are: IBM, BenQ, Samsung, and the domestic Yijie are also good.

You can go to Pacific Computer City** to see and filter.

One is the model of the original portable hard drive, and the other is the model of the bare disk. This means that the freeagent go is 500g

The hard disk model inside the portable hard disk is staa500301 2 3 4

A single disk is a hard disk with only one disk, and a double disk is a hard disk with two smaller capacities added together, of course, the fewer disks, the better.
