160G, 250G hard disk capacity is different, what else is different? except price .

Hard disk, in addition to capacity, there is a single disk capacity, the higher the capacity of a single disk, the better the performance of the hard disk, the same capacity of the hard disk, one is a single disk, one is a multi-disk, then the performance of a single disk is much better, and there is the speed, but now the desktop hard disk speed is 7200r m, there is no comparison, and what is the cache, 1 The larger the cache, the better, because the things in the hard disk are transmitted to the cache first,

The speed is basically the same now, it should be 7200 rpm.

The difference is probably caching. There are 2m, 8m, 16m, 32m, the bigger the better. Writing and reading is fast, simply put, loading things fast.

There is also a brand. However, the hard disk is only these brands, and WD's are recommended. Relatively stable.

If the number of disks used in the hard disk is the same, the larger the capacity, the higher the disk density, and the faster the read and write speed.

The speed of the hard disk is the speed of reading and writing, and theoretically, the read and write speed of a small hard disk may be a little faster than that of a large one, but it depends on what brand it is, and you should ask clearly when you buy it.

Your question is a bit unreasonable, it's the same brand, the same interface, I just say that it's been produced recently, it's basically the same, to say that it's different, maybe the thickness is different, and now the number of revolutions is the same, and the interface is different.

Everything else is the same, depending on the brand and model, some are 16m, some are 8m

A 200G hard drive represents a capacity of about 200 billion bytes.

Hard disks have solid-state drives.

SSD), hard disks.

HDD), hybrid hard disk (HHD, a new hard disk based on traditional mechanical hard disk). SSD uses flash memory particles for storage, HDD uses magnetic disks for storage, and hybrid hard disk is a kind of hard disk that integrates magnetic hard disk and flash memory. The capacity of a hard drive is measured in megabytes (MB MIB), gigabytes (GB gib), or terabytes (TB TIB), and the common conversion formula is 1TB equals 1024GB, 1GB equals 1024MB, and 1MB equals 1024KB.

However, hard disk manufacturers usually use GB, that is, 1G is equal to 1000MB, while Windows system still uses the word "GB" to represent the "GiB" unit (1024 conversion), so the capacity we see in the BIOS or when formatting the hard disk will be smaller than the manufacturer's nominal value. The capacity metric of a hard disk also includes the capacity of a single disk of the hard disk. The so-called single-disk capacity refers to the capacity of a single disk of the hard disk, the larger the single-disk capacity, the lower the unit cost, and the shorter the average access time.

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.

1TB = 1024GB, so 1TB is larger than 240GB. At present, hard disks are divided into mechanical hard disks and solid state drives, if it is a 1TB mechanical hard disk and a 240GB solid hard disk, then it is more expensive than a solid hard disk.

SSD Introduction:

An SSD is a computer external storage device based on persistent memory, such as flash memory, or non-persistent memory, and synchronized dynamic random access memory.

Differences Between Solid Hard Drives and Hard Disk Drives:

Solid hard disks do not have the rotating medium of mechanical hard disks, so they are extremely shock-resistant, and at the same time, they have a wide operating temperature, and electronic hard disks with extended temperatures can work at -45 +85. It is widely used in military, vehicle-mounted, industrial control, first-class monitoring, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields.

SSD Advantages:

Durable; Faster;

Easy to carry; More efficient.

Because 240GB is an SSD, it runs fast and currently costs more.

1TB is a mechanical hard disk, which has a large capacity, slow running speed and low cost.

1TB = 1024GB >240GB, that's for sure. 240GB is more expensive than 1TB There is a situation, 240GB is an SSD, and 1TB is a mechanical HDD, these are two different types of hard disks, the same capacity of the solid state is definitely more expensive than the mechanical one, and the different capacities, depending on the specific situation. If they are all mechanical hard disks, 240GB cannot be more expensive than 1TB, and when mechanical hard disks were released, there may not be such a capacity as 240GB, so the largest possibility of 240GB is a solid-state drive.

Let's look at the specifications and models.

Who said that 240g is cheaper than 1t.

Look. <>

1TB is 1000g 2TB is 2000g Please give points. Thank you.

A hard drive with a nominal 100G format will show 93G.

The root of the problem lies in the different base systems of the counts. The decimal system of the vendor logo is in decimal format, while the operating system is binary. If you are interested, you can take a look at the related entries on the encyclopedia.

In short, there is a fixed proportion of the difference. For example, the formatted capacity of a 500G hard drive is, and so on.

1000000000000 1024 1024 1024 = about 93g, but the difference caused by different base systems.

The actual capacity of the 250G hard disk after formatting is:

320g, the actual capacity is 298g

That's it. 400g*1000=400000m400000mDivide 1024=

Hard disk merchants use 1000m=1g, and the system is 1024m=1g

About around.

You can convert it to 240*(1000 1024) 3=

This is due to the fact that the manufacturer's production label is 1kb = 1000b, but the actual is 1kb = 2 10b = 1024b, so there will be an error. Of course, the above values are only theoretical, and the actual situation is related to the manufacturer's manufacturing process, but it is also around that value.

According to the conversion standard, the actual space of the hard disk is the representative space, so the actual size of 250G is. View the original post" for adoption.
