Is it better to buy an SSD or a portable hard drive?

Of course, a mobile hard drive is better because it is convenient and can be taken with you, while an SSD cannot be taken away and can only be used in a fixed place, while a portable hard drive can be taken away and can be used in that place.

It depends on your own needs, general SSDs.

It is mounted on a laptop or desktop computer and is intended for fixed use. And portable hard drives.

It can be carried around, easy to use anytime, anywhere, and the interface of the solid-state drive and the interface of the mobile hard disk are generally different. It's not necessarily convenient for you to use.

If you don't move, it's faster to buy an SSD, and it's more convenient to move a hard drive if you move it more often.

Personally, I think SSDs are better because SSDs are faster and more stable to use.

If you use it all the time, the SSD will definitely be better. If you just want to back up your data, it is more cost-effective to store a portable hard drive.

I think of SSDs because SSDs have fast transfer speeds and stable properties.

It is better to use an SSD for a portable hard drive, as opposed to a mechanical hard drive, which has the following advantages:

1. No magnetic head, fast random reading, fast reading and writing speed.

Using flash memory as the storage medium, the read and write speed is faster than that of HDD, saving time for copying data.

2. No noise, low heating.

Because there is no mechanical motor and fan, the noise level is 0 dB when working, which is quieter and the power consumption is lower than that of traditional hard drives.

3. Shockproof and anti-fall, data is safer.

There are no mechanical moving parts inside, no mechanical failure will occur, and there is no fear of collision, shock, vibration. In this way, even when moving at high speeds or even with flipping and tilting, it will not affect normal use.

4. Large operating temperature range.

HDDs can only work in the range of 5 to 55 degrees Celsius, while most SSDs can work at 10-70 degrees Celsius.

5. Small and lightweight.

Compared to regular inch HDDs, SSDs are lighter in terms of weight, making them easy to carry around.

Precautions for the purchase of mobile hard disks:

1. Mobile hard disk shell.

The materials of mobile hard disk enclosures are generally divided into metal and plastic. Generally speaking, the compressive and heat dissipation performance of the metal shell will be better, while the plastic shell has relatively better advantages in terms of shock resistance and weight. Therefore, choose a metal case for mechanical hard disks and plastic shells for solid state drives.

2. PCB board control chip.

The control chip on the PCB of the mobile hard disk is directly related to the read and write performance and stability of the product. At present, the control chip is mainly divided into two grades: high and low. High-end chips** are more expensive, with excellent stability and compatibility, suitable for demanding users.

The stability and data transmission performance of the low-end chip are relatively poor, but they are also enough to cope with the daily work needs.

3. The external interface of the hard disk enclosure.

At present, the common interfaces of mobile hard disks include the eSATA interface.

How to put it, each has its own strengths.

The pursuit of lightness and speed, or solid is good, but not cost-effective.

Mechanical disk, the speed is not as fast as the solid-state, but it is cost-effective.

If you are considering the issue of data recovery, it is recommended to lift the machine.

The three major brands in the mobile SSD market, Seagate, Western Digital (WD), and Hitachi, are all more durable and are good choices, as long as you pick a style you like.

The biggest feature of portable SSDs is the slim body design, which makes them more portable. At the same time, the material is made of aluminum alloy, which is more durable and durable, and is not easy to damage. Finally, in terms of read speed, this portable SSD has a read speed of 430MB seconds and has a strong data transfer capacity.

DRAM is used as the storage medium, and the application range is narrow. It mimics the design of traditional hard disks, can be configured and managed by file system tools of most operating systems, and provides industry-standard PCI and FC interfaces for connecting to hosts or servers.

Advantages of SSDs compared to HDDs

1. No magnetic head, fast random reading, very small reading delay. According to the relevant tests, under the same configuration of the two computers, the laptop with the SSD took only 18 seconds from boot to desktop, while the laptop with the traditional hard drive took a total of 31 seconds, almost half of the difference.

2. Relatively fixed reading time. Because the addressing time is independent of where the data is stored, disk fragmentation does not affect the read time. DRAM-based SSDs have extremely fast write speeds.

3. No noise. Because there is no mechanical motor and fan, the noise level is 0 dB when working. Some high-end or high-capacity products are equipped with fans, so they still generate noise.

Western Digital, Toshiba, Patriot, Hitachi, Rice. The above five brands are all foreign brands except Aigostar, and they all have independent patents and intellectual property rights in mobile hard drives.

1. Western Digital:It is a data storage device brand from the United States, founded in 1970, and was first recommended among the eight major mobile brands, because it is excellent in the development of mobile hard drives, adhering to the concept of quality first, coupled with digitalization and professional management system, it is favored by countless consumers.

2. Toshiba:This brand is from Japan, founded in 1875, formerly known as Tokyo Shibaura Electric Co., Ltd., its products mainly include household appliances, heavy motors, communications, electronics, digital products, etc. Toshiba has always had a very good reputation in virtual space storage, and its sales are also very good.

3. Patriot:Aigostar was founded in 1993, is a well-known digital technology brand in China, to say which brand of mobile hard disk is good, this brand is worth recommending, Aigostar focuses on the research and development of IT products, so it is welcomed by many consumers, hard disk low-end to high-end product line is rich.

4. Hitachi:Hitachi was founded in 2003 as a relatively late addition to previous brands, and in terms of product categories, Hitachi Global Storage Technologies caters to the needs of the market and offers a series of industry-leading product portfolios, including 1-inch, inch-inch and in-inch hard disk storage devices and solutions.

5. Rice:Founded in 1989, it is a storage device manufacturer in France, has a certain reputation, has been known for its quality and in the industry, its mobile hard disk is also very recommended, and many of its products have won awards in the world. LESER has strong R&D strength and perfect after-sales service.

First of all, it must be noted that the internal hard disks of the mobile hard disks produced by Seagate are all mechanical hard disks, and there are no solid state drives, so there is no comparison. Generally speaking, the mobile hard disk with the mechanical hard disk as the core produced by Seagate is a very practical mobile storage product.

If you are interested in specific product information, the best way is to consult the Seagate official product introduction on portable hard drives to get the most comprehensive product information.

It is recommended to use mechanical hard disks for mobile hard disks, such as the pursuit of fashion, high speed, and a straight waist bag, and solid-state ones can also be selected.

Of course, it's a lot more solid. No matter how fast it is. It's much better than the machine in terms of volume.

Of course, it is solid-state, light, stable, fast read and write, and not afraid of falling.

What if you're after capacity? Just mechanical, because the capacity is easy to make very large, but also cheap. It's easy to make backups and store some things.

If you happen to be one of the few people who need a mobile hard drive very quickly, and it doesn't need to be too big, and you are not short of money, then buy a portable hard drive for an SSD, which is about the same as a large USB flash drive.

Hello, generally speaking, mobile hard disks belong to mechanical hard disks.

Because the large capacity and speed required by portable hard disks are basically enough, there is no need to use SSDs.

And** cheaper than SSDs.

SSDs are made of flash memory particles (i.e., memory, ***, USB flash drives, etc.), so there are no mechanical parts inside the SSD, so that even if it moves at high speed or even when it is flipped and tilted, it will not affect normal use.

It is good to use an HDD. SSDs have a small capacity, are expensive, and are completely useless.
