Why are there so few laptops with 2TB or more hard drives?

Because people who buy computers buy on demand, they will choose the right or sufficient configuration according to their needs to reduce their budget, and they are not willing to spend more money where they are not needed. In general life, home computers and game computers, as long as there are no special needs, 1T hard disk can fully hold all files, and even a lot of big sisters (manual funny) and movies that are not particularly pursuing picture quality are quite enough. So why do users have to spend more money to buy space that they can't use, it's better to add some solid state with this money, and manufacturers also take this into account, so they generally have built-in 1t hard disks to meet most customer needs.

Taking a step back, if the user feels that it is not enough, it is not difficult to upgrade it by himself in the later stage, so it is not necessarily necessary to have a large hard disk capacity when purchasing. As a result, there are laptops on the market that do not have large hard drive capacity. <>

Because the average person can't use so much capacity at all, many people use 500g is enough, and the hard disk capacity is large, the money is expensive, who will buy it. And some people have this large-capacity demand can buy a 2TB hard disk and install it, and the merchant is not stupid, how can he sell a computer with more than 2TB. At present, the largest capacity of the hard drive is Seagate's ST5000LM000, but this one is 15mm and cannot fit into a laptop.

The largest capacity hard drive that can fit into a laptop is Seagate's. ST2000LM015 (ST2000LM007), 7mm thickness, ** is not expensive, retail is only in the early 600s. Manufacturers are reluctant to use it, mainly because of insufficient demand, and 1t without special needs is definitely enough, and there is no need to be larger.

Custom configuration ** is definitely expensive, users are not stupid, the same thing, why not buy it yourself. <>

2t=2024g。According to the algorithm, 1t=1024g=1024*1024m=1024*1024*1024k. But in fact, if you buy a 1TB hard drive, it should be about 931g, because it is calculated by an order of magnitude of 1000.

1。Hard disk is one of the main storage media of a computer, consisting of one or more aluminum or glass discs. The disc is covered with a ferromagnetic material.

2。Hard disks include solid-state drives (SSD disks, modern hard disks), mechanical hard disks (HDD traditional hard disks), and hybrid hard disks (HHD is a new hard disk born based on traditional mechanical hard disks). SSDs use flash memory chips for storage, HDDs use magnetic disks for storage, and hybrid hard disks (HHD:

Hybrid Hard Disk) is a type of hard disk that integrates magnetic hard disk and flash memory. The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive.

1 x 2TB hard drive is good. This is necessary if you have important data that needs to be backed up to another hard drive. Plug in the backup disk when it is in use, unplug it when it is not in use, and never run it all the time, otherwise the value of the backup disk will be lost.

In terms of power consumption:

If the power consumption of a 1TB HDD is 50W, two are 100W, then if a 2TB HDD is 80W, a 2TB HDD will have an advantage.

In terms of storage speed:

1 2TB hard disk still wins, why, the smallest storage unit of the hard disk is the block (block), but from the hardware alone, if from the hard disk control software, the smallest unit is the section (bit), if the block of the 1TB hard disk is arranged like this: 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0, then the 2TB hard disk is arranged like this: 0101010101010101, because his capacity is higher than 1TB, Therefore, the density of the 2TB hard disk must be very large to install 2TB, the higher the density, the shorter the time for the hard disk to read a block, and it is naturally faster.

The calculation result of calculating the capacity of a 2T hard disk is as follows, if it is partitioned, the actual capacity may be slightly reduced, but not too much, and the partition table will only occupy a small amount of space.

2t = 2000g = 200000m

200000m*1000/1024*1000/1024*1000/1024=

The actual display size of the computer after formatting:

Take a 120GB hard drive as an example:

Vendor capacity is calculated using the following method: 120 GB = 120,000 MB = 120,000,000 KB = 120,000,000,000 bytes.

Converted to operating system: 120,000,000,000 bytes 1024=117,187,500KB 1024=114,.

According to the above conversion, the actual capacity of 2T hard disk is: 2*1000*114 120=1900G.

In the computer, binary system is adopted, so that the calculation of capacity in the operating system is based on 1024 as a base, 1KB per 1024 bytes, 1MB per 1024KB, 1GB per 1024GB, and 1TB per 1024GB; In terms of computing capacity, hard disk manufacturers use every 1000 as a base, 1KB per 1000 bytes, 1MB per 1000KB, 1GB per 1000MB, and 1TB per 1000GB"Shrinkage"。So the actual display size of the computer after 2t formatting:

2TB HDD actual capacity = 2000 1024 1024 1024 * 1000 * 1000 * 1000 = 1862GB.

Generally, 500GB is sufficient. If you want to play games and watch movies, 1TB is the minimum requirement.

Look what you're doing, hehe.

Generally, the mainstream is now 500g.

If you have a lot of movies, you can consider a large hard drive, hehe.

I heard that the current 2T is not very stable, and the technology is not very mature.

Buy one, now 2TB is also cheap, Seagate LP 2TB is only more than 500.

There are some movies that you watch once and you won't move again, unless you want to collect unpopular things, which is generally enough. I still use 80g.

Rich children, 160g can't be used up...
