Why is a 2000G hard drive so expensive?

Because his memory is large, the technical support that people need, or the materials they need, will definitely be expensive.

Because the memory of the hard disk of 2,000 gigabytes is too large and the production cost is high, it will be sold very expensive.

If you have two or two cars, this hard drive, so there's a lot of space, and God he's coming up, because it's loaded a lot, so it's expensive.

Because this capacity is quite large, generally. It is used more in industry.

A hard drive of more than 2,000 is very expensive, because the bigger the hard drive, the more capacity it has, so it will be expensive.

Of course, this is because of the problem of capacity, this thing is expensive is large capacity, the bigger it is, the more expensive, and there is also the problem of brand.

The main reason why it is expensive is because of his large memory, and this memory is on top of a lot of mobile phones and computers.

Because this thing is particularly expensive now, generally speaking, things that exceed one g are more expensive.

Actually, the bigger it is, the more expensive it will sell, because the one he makes will be different.

This is for sure, because two or two thousand g don't know this memory, so one of its ** must be very expensive.

That memory is sold so expensive, it should be that the taboo card is very expensive.

Hard drives are sold at cost plus brand, how much does it cost to sell with profit? It is necessary to look at the comparison of similar products in the market.

Hard drives that sell 20 2000 g are so expensive, and you have to look for some introductions to hard drives.

The 2000 g hard drive is so expensive because of its better quality.

Equal. 2000G is 2000GB, in the hard disk capacity unit T this unit is 1000 times that of the G unit, 2000GB = 2TB, it should be noted that the hard disk capacity has a reserved part for error correction, so the 2TB hard disk bought in the computer to view the capacity should be about, as shown in the following figure:

The difference between a 500G hard drive and a 1000G hard drive is that the capacity of 500G is twice as small as that of a 1000G hard drive.

The specific performance is as follows:

1. The capacity is different: 1m 1024kb, 1g, 1000g hard disk is twice as large as 500 hard disk g.

Now if you want a mechanical hard disk, it must be recommended to choose the most cost-effective one with a capacity of 1t, and the hard disk has nothing to do with the size of the hard disk capacity.

The capacity of 1000G is twice that of 500G, and the amount of data stored is also twice as large. If the brand and type are the same, it's just a difference in capacity.

2. Different categories: SSD is a hard disk made of solid-state electronic memory chip array, composed of a control unit and a storage unit. The read and write speed is fast, the computer boots up and is noiseless, and the weight of the solid state is also very light, only 20 30 grams.

But the capacity is small, expensive, and the life is short. The ** of a 500g HDD is almost equal to the price of 128g of Good.

Mechanical hard disks are also the ordinary hard disks that we usually refer to. At present, the vast majority of computers still use mechanical hard disks, such as 500G, 1T, and so on.

Advantages: large capacity, low price, long life. Cons: Runs too slowly.

From the ** point of view, the 1T hard disk is now about 700 yuan and nearly 800.

A 500g hard drive costs about 400 yuan.

Therefore, there are more than two 500g ones on ** than one 1t one.

In addition, in terms of use.

Two 500G hard disks require two search car positions and two lines in your chassis to supply power.

And the data exchange between the two.

It's also inconvenient. The power consumption of one 1T hard disk is obviously less than that of two 500G.

Other than that. It's also easier to store data.

Swapping between two physical devices is avoided.

Of course, if you need to use disk array technology, it is RAID technology.

Then two 500G can only provide 500G capacity after forming a RAID, but it must be better in terms of data security, because if one of the hard disks is broken, another hard disk can restore the data intact.

As for whether you want to ask whether it is good or not, it mainly depends on the area where you use them, if it is a general household.

Then I recommend you to choose 1t

If it's a data server.

Store some important data.

You can consider RAID technology.

But generally at home.

RAID technology makes it not very widely used.

I don't know if you're satisfied.

2 500 is good, because the life of the hard disk is limited, and the first hole is rented for fear of bumps.

If a hard drive is damaged, all the data will be lost.

2 hard drives can also be raided.

PS: 2 x 500 ** >> 1 x 1000.

1TB hard disk is good for wild rent.

1. Power saving. 1TB only has one hard disk, two 500s are two, and two hard disks definitely cost more power than 1 Fanzhao hard disk.

2. Fast speed. Today's desktop hard disks, a single disk is 1T, and the larger the capacity of a single disk, the faster the speed. The two 500g may be the old hard disks with a small single disk capacity, or they may be made by 1T with a problematic reduced capacity, which is definitely not as fast as 1T.

3. The probability of failure is high. 2 hard drives are definitely more likely to fail than 1 hard drive. Moreover, in the case of the above principle, 1T is the mainstream single-disk capacity, and the stability of 500G is somewhat questionable.

When many customers have problems with the hard disk, they will always consult a professional data recovery company through **or QQ**, when the customer hears the hard disk opening**, the first reaction is why the hard disk is so expensive, and the following data center will solve your doubts:

1. The hard disk is opened to replace the head, and a matching head of the same model is needed as a spare part, this is the cost, and now the general situation is to recover the data charge, and the failure is not charged, and the merchant will lose a disk if it fails. Cost analysis behind the opening: the accessories of the common disk are generally between 200-500 yuan, according to the severity of the hard fault loss of the amount of accessories will be different, on average, the loss of two accessories is normal, plus the cost of labor, equipment, etc., the starting price of 500 yuan is reasonable, the larger the capacity, the higher the opening.

2. Technology: Skillful operation is required to open the disk, and it takes more time, energy, and spare parts to be in a dust-free environment (many domestic data recovery companies use dust-free workbenches) and many hard disks can not be replaced with head data, and some firmware areas are damaged and scratched on the disk surface (here is a reminder that when the hard disk is powered on, it cannot be powered on repeatedly).

To sum up: hard disks are valuable, data is priceless, remember to back up often.

What kind of hard drive needs to be recovered on the disk.

Open disk data recovery is a special case of hard disk physical failure data recovery. When any part of the magnetic component of the hard disk (such as the head, preamplifier, voice coil, drive arm, etc.) is damaged, aged or deviated, the hard disk will not be recognized normally, and the phenomena manifested are: there is obvious abnormal noise, the motor does not rotate, or everything behaves normally but does not recognize the disk, etc.

For such failures, it is necessary to disassemble the hard drive for data recovery.
