What do I need to pay attention to when buying a portable hard drive?

Buy brand goods, have an invoice, and ask for a national warranty, because 80% of the mobile hard drives on the market are assembled goods, and it is easy to pretend to be ** licensed.

Pay attention to the read and write speed, whether there are bad sectors, power supply problems, capacity, and seismic performance. Be sure to have a warranty!

It depends on the size of the capacity, and if possible, check whether there are any bad sectors. See if the actual capacity is as large as the one on the outside. Then there is the brand.

If you don't know it, don't make a move. Finally, look at the warranty period. Generally, it is not good to be too long, and it is not good to be too short.

A year or so is fine.

Generally speaking, buy the ** of the big factory brand, use it carefully, pay attention to maintenance, and use it for a few years is not a problem. As for whether to be portable or desktop, according to your actual needs, choose yourself, the difference in ordinary use is not so big, that is, the desktop type generally has an external power supply, and the volume is larger, but the work is more stable, the adaptability is stronger, and the heat dissipation is relatively better, while the portable mobile disk is mainly easy to use and carry, but it is more picky power supply.

Personally, I suggest that if you buy Western Digital and Seagate, after all, they are more professional and focused, and the use of their own products is more secure in design and craftsmanship. I have a few mobile disks (as well as MSI, Lenovo, Toshiba), the most satisfying thing for me is these two, low noise, low heat, easy to use, quite fast, there has been no problem so far, of course, Western Digital is a little more cost-effective, Seagate said that the new technology and high material, in addition to good looks, does not give people a special feeling. If you buy, you can buy it in the computer city, it is best to buy it in the authorized **, remember to invoice and check the packaging (note, check whether the sequence of the packaging and the mobile disk shell and the hard disk detection software is consistent, as well as the use of the hard disk, the power-on time, generally not more than 3 hours), otherwise it is likely to be pitted, however, it is recommended that you go to Newegg, excellence, these reputable ** see, I generally buy it here, convenient (free shipping), rest assured (guarantee**),** also relatively cheap, It's up to you to choose.

Also, most brands of mobile disks have a relatively good after-sales service, but as far as my experience is concerned, as long as it is used and maintained properly, there will be no problem, that is, the oldest, MSI V3 120G that thinks it is relatively the worst, so far, there has been no problem with the mobile disk itself.

By the way, there is also hope to note that the data cable problem, the hard disk can often be a few years without problems, but the data cable is likely to be replaced once a year, especially in humid areas, it is easy to occur rust phenomenon, directly is poor contact or insufficient power supply, affecting the normal use of the mobile disk, long-term will also damage its life, so, the data line should still pay attention to protection, conditions permitting, with good quality is the best.

Here's a ** for you.

This is the most authoritative mobile hard disk in the country****.

RPM capacity.

And be careful not to buy parallel goods.

Capacity, speed, and interface are the three major elements.

Now it's basically a capacity of more than 250G, SATA interface, preferably 7200 rpm.

Calendar, Seagate, Western Digital are all good brands. Well-known e-shopping items such as JD.com and Newegg** are available for express delivery.

Attention should be paid to the use of mobile hard disks:

1. Try not to buy products that are too cheap.

2. It is best not to have more than 2 mobile hard disk partitions.

3. It is best not to plug in the computer for long-term work, the mobile hard disk is used to temporarily exchange or store data, not a local hard disk.

4. Do not defragment the disk of the mobile hard disk, otherwise it will easily damage the hard disk. 5. The mobile hard disk is not recognized or the copy will be disconnected, and the above content does not know that it has played a due role in the correct use of the mobile hard disk?

Don't shake it or cut off the power during operation, nothing else is special.
