Recently, I want to change a hard drive, so please help me see what kind of hard drive is better

Your motherboard is an 845 chipset, which can generally support 160G, if not, flash the BIOS, and you can bring the host when you buy a hard drive. Let the people at the computer city get it for you. No, they'll help you get it.

Hard disk is recommended to buy WestJet.,As for the copy system,You can use ghost.。。。 But I don't think you can use it.,Let the people in the computer city help you get it.,Hehe.。。。

If you do want to use it yourself, add.

Buy a Seagate's, it's estimated that it's more than 400 points, and it is recommended that you install a new system on a new hard disk, just copy the original important data to the new hard disk, ghost's system is not easy to use, and it's easy to have problems.

Don't know what chipset your motherboard is. If it's 845, there won't be sata. Seagate 160G 8M cache with IDE. The IDE also has a 2M cache. Be careful. Generally speaking, you can see it by looking at its number.

Hard drives are not very cheap these days. More than four or five hundred yuan. You look first.

Yes, if not, you can flash the BIOS

If you want to move the things from the old hard disk to the new hard disk, you can connect both hard disks to the computer.

You don't need to reinstall the system if you keep the hard disk in the past, you can set the hard disk with the system as master.

Hard drive Seagate's is better.

160g is not very large and can be supported.

Now buy a hard drive, the bigger it is, the more cost-effective it is recommended to buy a 160g Seagate.

You can use ghost to simply install the system.

It depends on your money, at least 80 g or more.

If you still have doubts about solid-state drives this year, you can only say that it may not be connected to the network in the village. Solid-state development to now, has basically replaced mechanical hard disk, even if you buy a computer now, solid-state is a little more expensive than mechanical, of course, expensive is expensive in people's performance. I don't want my computer to be reminded to start a few points, so let's honestly change to a solid state.

1.Quick start, no motor to accelerate the process of rotation.

Under the same configuration of the two computers, a laptop with an SSD took only 18 seconds to turn on the desktop and a laptop with a traditional hard drive took a total of 31 seconds, which is almost half the difference.

3.Relatively fixed read time. Because the addressing time is independent of where the data is stored, disk fragmentation does not affect the read time.

4.DRAM-based SSDs have extremely fast write speeds.

5.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.

6.Low-capacity flash-based SSDs consume less energy and heat in operation, but high-end or high-capacity products consume more energy.

7.There are no mechanical moving parts inside, no mechanical failure will occur, and there is no fear of collision, shock, vibration. This does not affect normal use, even when moving at high speeds or even with flipping and tilting, and minimizes the possibility of data loss in the event of an accidental drop or collision with a hard object.

8.Wider operating temperature range. A typical hard drive can only work in the range of 5 to 55 degrees Celsius.

While most SSDs can operate at -10 to 70 degrees Celsius, some industrial-grade SSDs can also operate in temperatures ranging from -40 to 85 degrees Celsius or even greater.

9.SSDs are smaller and lighter than HDDs of the same capacity.

SSDs are definitely better than HDDs.

At present, there are two types of hard disks used in computers: mechanical hard disks and solid state drives. A brief comparison of the two types of hard drives:

Through the mechanical structure, the mechanical hard disk is rotated by the magnetic head on the rotating platter to find the sector where the file is located when reading and writing, and the motor runs at high speed when running, resulting in vibration and perceptible noise, and the hard disk is easily damaged if used in motion or vibration, and the temperature range that can be withstood during work is smaller.

SSDs are mostly composed of master cache and flash memory, there is no mechanical structure, no seek when reading and writing, extremely fast and efficient, noiseless and shock-resistant during operation, with low-power standby function, and can withstand a larger temperature range than HDDs when working.

Through the above comparison, if ** is not a factor to consider (SSDs will be more expensive), it will be better to use SSDs.

If you really don't understand, you can directly find a brand store, and then carefully compare the parameters, so that you can see at a glance.

The hard disk is the same as the old amplifier, with a mechanical fork, so it is slow to read and write.

The inside of the SSD is the same as the USB flash drive, and it has an electronic structure, so the read and write speed is fast.

Let's change to an SSD. Solid state drive, now solid state is not expensive, speed is a cool word? Mine is an SSD laptop, powered on for 10 and 14 seconds. win7

It is recommended that you change to an SSD, which is not too big, and can be equipped with commonly used applications, so as to save money.

You can prepare another mobile hard disk.,Install games or something.。。。

As long as it is SATA port, it is supported, but it does not exceed 2TB, 1T is good, I think it is WD black disk, followed by Seagate. In addition, let's talk about it, look at the warranty WD3Y, ST's 2Y, think about it yourself, in fact, the one with good performance is Seagate.

Samsung, Hitachi can be, the main focus is on cache size, as well as spin speed. Of course, the higher the speed, the greater the heat, and the current hard disk, there is no noise.

It is not recommended that you change, 250G is enough for normal use, and the speed and SSD should not be blindly pursued, if you want to store it directly with an external mobile hard disk.

Cloud technology financial all-in-one machine to help you answer:

Choosing a good portable hard drive for personal use is recommended. 1. Pay equal attention to quality and performance, the set of mobile hard disks is more worry-free, the characteristics of mobile hard disks are that the quality guarantee coefficient is high, and different manufacturers often add additional functions such as software and hardware encryption to their products, in order to improve the practicability and application scope of the hard disk, this kind of product can enjoy a complete set of product warranty services, which makes users worry a lot, as long as there is a problem with the hard disk, the whole thing can be taken back to the relevant businessmen, manufacturers, and maintenance points. The disadvantage is that the price of this type of product is higher.

2. To save money, mobile hard disks can also be DIY, buy a mainstream performance, price of notebook hard disks, and then with a large factory hard disk enclosure, the assembly will be completed. At present, in the category of notebook hard disks, well-known manufacturers such as Hitachi, Western Digital, Seagate, and Samsung are all supplied, and the mainstream capacity is 500G, 1T, 2T and other levels. In terms of speed, the current market is the coexistence of 5400 rpm and 7200 rpm products, such as Seagate's Momentus series, Hitachi's 5K series, and Western Digital's VT are all very popular 5400rpm 500G products, and in terms of 7200 rpm, Hitachi's 7K series, Seagate's Momentus series, and Western Digital's KT series, ** have become reasonable, and users with performance requirements may wish to consider more.

3. Pay attention to the big and small places, keep in mind the use skills, the equipment is bought, and treat it well, so that it can fully play its functions. Including do not implement hot swapping during data transmission, try not to let the hard disk body bumpy, prevent external interference such as electromagnetic, dust, water vapor, etc., do not frequently format the operation, etc.

The mainstream brands on the market are Western Digital and Seagate, and there are also niche brands such as Samsung and Sandisk, which are also the most expensive. As for how to choose, each has its own advantages and disadvantages, for example, Lenovo and ASUS computer 7200 rpm hard disks are generally used by Seagate.

I am a wholesaler and retailer of computer accessories, and you can find me if you need anything, and all kinds of brands of hard drives are used, absolutely licensed.

If you want to change it, you have to see what port of hard disk your machine motherboard supports.

Such as parallel port or serial port.

Generally buy Seagate, from 200 to higher.

The new hard disk can query its usage time through the software HD tune, which is to see the power-on time. 0 for new hard drives

Generally, it is 160g or 250g, and at present, these 2 models** are around 300 yuan and 360 yuan.

Please take the trouble to list your computer configuration first, and then it is easier to get everyone's help.

If you want speed, buy an SSD. Samsung, Pucot, Micron, if the computer is older, buy Intel and Kingston.

More than 128, more than 300.

If you want capacity, buy Seagate and Western Digital hard disks of more than 2T. Around 500.

120g for home use is sufficient.

This is a very old hard disk about 10 years ago, and the interface is also SATA II generation, so you should replace the backup as soon as possible, otherwise if it can't start that day, important data will be very troublesome; Now there are 3 options to replace this hard drive:

1. If you are making an operating system disk, you can directly change to a solid state drive, with a capacity greater than 256G, the current price is about 700 yuan, and the capacity is slightly smaller 128G (about 400 yuan). According to your other hard disk situation, the size of the choice, 2, if you are just a storage disk, you can replace it with a larger capacity of mechanical hard disk, first consider 500g (about 300 yuan) or 1t (400 yuan) or so.

3. If you want to optimize the model, you can consider the combination of solid state drive + mechanical hard disk, and the capacity is determined according to the amount of money you want to invest.

While your motherboard may not be compatible with SATA III connectors, you should prioritize mainstream and advanced accessories (no one is buying new SATA II connectors right now).

Now the mainstream is a 1TB mechanical disk, such as Seagate's, **330 or so.
