What does HDD 7200 11 or 7200 12 mean?

The higher the 11 or 12 in the back, the faster the speed, anyway, when you buy it, you buy the back value is larger! ~

It is highly recommended that LZ buy, there is a serious problem with this batch of Seagate, most users will have the problem of not being able to find the hard disk, the quality is not guaranteed, LZ should have heard of it.

12 denotes the algebra of the Seagate hard drive.

7200 rpm per second, the reading speed of the general belt behind, I have only seen 8m, 16m, 32m, I don't know where your 11 and 12 come from.

a) The main difference between Seagate 500G and Seagate 500G is in the tab and HDD edge sections.

2) 500g is significantly higher than 500g because the former has a double platter design, which requires more space to store the platter; The latter is a single platter design, which is very thin and light, and at the same time, the heat dissipation and power consumption are also somewhat lower than those of double platters.

c) The 500G model is ST3500320AS, while the 500G model is ST3500410AS. As you can see from the models, the models of the two hard disks only have the middle "320" and "410" parts, and "32" represents the 32M cache and dual platter design; "41" indicates a 16M cache and a single platter design.

4) Both 500G and 500G are designed with anti-PCB boards, but the back circuit can be seen that the PCB wiring of the two hard disks is obviously different.

5) The lower left corner of 500g is designed with circular trimming, while 500g is a straight trimming design, and each corner has a small triangle with protrusions.

It is advisable to choose the latter!

The 7200rpm of the hard drive means 7200 (revolutions per minute). The time required for each rotation is 60 1000 7200 = milliseconds, then the average rotation delay is milliseconds (on average, half a revolution is required).

For a 5400 (revolutions per minute) hard drive, the average rotation delay time is 60 1000 5400 2 = milliseconds. 7200 rpm is theoretically 15% faster than 5400 rpm.

7200 rpm means 7200 revolutions per minute.

Common hard disks are mainly 5400 rpm, 5900 rpm, 7200 rpm.

5400 rpm like most laptop hard drives, earlier inch IDE disks. Seagate's new monitor panel is 5900 rpm. The common inch SATA disk and high-end notebook disk 7200 rpm.

Most of the SCSI and SAS hard disks used by servers are 10,000 rpm and 15,000 rpm.

The high rotational speed brings better performance and faster seek to the hard drive, but it also increases noise and power consumption.

A long time ago, Quantum's big hard drive was 4200 rpm.

7200 rpm, some hard disks are 5400 rpm, which is a parameter of the hard disk.

The speed at which the hard drive spins per minute.

r=round.

p=per each.

m=minute points.

Do you understand the transfer?

Upstairs, not every second, it's every minute.

7200 rpm, of course.

The rotational speed of the hard disk, in rpm minutes.

The rotational speed of the hard disk The previous hard disk had 4800 5200

Upstairs is right, the labeling method of Seagate hard drives, the front is the speed, and the back is several generations of products, usually the higher the number, the newer the technology.

The estimated 7200 is the RPM.

10 11 12 means how many generations of hard drives, right? I guess.

First, your hard drive is Seagate.

Second, did you buy your hard drive in the last 2 years?

Third, you're not using the IDE hard drive of the past, are you?

Fourth, on the surface of the hard drive, a sticker, in the upper right corner, is printed with the word Seagate, and below is the model number, in the past, the old Seagate did not have, I remember it should be to start.

The main reason is that the single-disk capacity and the maximum capacity are different, and the cache capacity is also different.

It is the first product in the Barracuda series to feature vertical recording technology, with a maximum capacity of 750GB, a single disc capacity of 188GB, and a single disk capacity of 160GB for capacities of 500GB and below. The maximum cache size is 16MB.

Yes, the next generation has advanced in vertical recording technology, with a maximum capacity of 1TB (1000GB), a single disk capacity of 250GB, and a cache capacity of 16MB and 32MB.

All are Seagate desktop computer hard drives, and 7200 represents a hard drive speed of 7200 rpm** per minute).

And the following 11 and 10 represent algebra.

11 is the next generation of 10, mainly because the capacity and cache size of a single hard disk have been increased.

The 11th generation has newer products, with a single disk capacity of 320GB, and products with a cache size of 1TB use this. The 500g product has a single disc capacity of 250g.

The 10th generation capacity includes 200GB, 250GB, 320GB, 400GB, 500GB, and 750GB, of which the 200GB model is equipped with 8MB cache, the 250GB model is equipped with 8MB 16MB cache, and the other higher capacity models are all 16MB. The maximum single-disc capacity is only. Smaller than the 11th generation.

So the speed difference between the two is quite large. The top speed of the 11th generation can even reach 110mb s, and the 10th generation has less than 70mb s.

The 12th generation is the latest generation of Barracuda. Generally speaking, other standards are the same, which is the case of Min Zao than the other to bridge the slow bird advanced, the speed is slightly faster, and the technology is updated.

There is a difference, but it is not very obvious. Specifically, it depends on the parameters of the hard disk cache.

It represents the twelfth generation of products, and the most important thing is that it is a single disk, and a single disk means that it is faster to read and write data. Therefore, it is certainly good. You can also go and take a look at this**, there is data on it, and you can see which one is faster at a glance.
