Two hard disks, a single disk capacity is 80G, which seek time is faster?

Now the 80G hard disk is mostly the old model, and the seek speed is slightly slower than the new model of the hard disk, but it is almost not felt. The 250G hard disk on the market should also be a single disk, and the 320G one is a double disk, so the 250G hard disk is slightly faster than the 320G hard disk seeking speed (the computer newspaper has been evaluated), and the old 80G hard disk should be slightly faster or about the same. If you want to buy or don't buy an 80G hard disk (unless commercial), the capacity is too small, and there is no cost performance, buy a larger capacity.

Seagate's performance is slightly better, Western Digital is more cost-effective (Western Digital's heat dissipation has been very good recently), Hitachi, it's a bit noisy. Take your pick. If you often ** movies or something, buy a hard drive with a larger cache, which is good for performance and hard drive life.

I can't say, depending on the specific indicators, if a brand of unified series of hard disks, it should be 80G a little faster. Barely felt.

The smaller the number of disks, the faster (80GB). With more disks, the number of heads will increase, and so will the weight.

80's. The one below says that 250 cache is large?

Now 80 250 160 320 are not all 8m cached?

It is essential to know the specific model.

Two discs, three heads.

The capacity of a single disc is fixed, so the integer result of the total capacity divided by the capacity of a single disc + 1 = number of platters 120 80 + 1 = 2

A platter has two sides, so the integer result of the total capacity divided by (single disc capacity divided by 2) = the number of heads will be +1 if the total capacity is not divided

Two disks with two heads.

Although a single disk is 80g, there are problems in some areas and it is blocked, so you have to buy a single disk to buy a hard disk.

HDDs are available in single-disc and multi-disc versions.

Nowadays, the commonly used hard disks, less than 1TB are mostly single-disk, and more than 2TB are multi-disk.

SSD hard disk storage principle is different, there is no disc!!

That's right, the fewer hard drives, the better, even if it's a hard drive, a single platter is better than multiple platters.

80's good.

Now there are 250g single-disc dishes.

With 2 hard disks, the data will be copied very slowly in the future.

Yes, the upstairs (technician) is particularly right, saving electricity is the last word! There is also a small dry sound of Western Digital.

No, some drives will block part of the capacity of one of the platters in order to reach a certain capacity. For example, HTS725032A9A364, with a capacity of 320G, is packed with two discs, and has a single disc capacity of 250G, shielding part of the capacity of one of the discs, according to your formula, 2 320 3 = So, your formula does not apply to all hard disks.

WD is good, LZ to speed, buy a single disc is good, the cache is 16M, consider the price, buy a double disc, but only cheaper than more than 30, in general, a single disc is better than a double disc in all aspects!

, the capacity of a single dish is estimated to be 125g

RE16 is a 16M cache, and Hitachi is an 8M cache, which theoretically says that the caviar read and write speed is faster.

。。Of course, the lower the better. The seek time of different types of HDDs is also different, that is, the average value of the time it takes for the head to move from the initial displacement to the track where the data is located after the HDD receives the instruction, which is one of the important performance parameters to characterize the read and data rates of the HDD.

Seek time refers to the average value of the time spent by the hard disk after receiving the system instruction, the head moves from the beginning to the track where the data is located, which reflects the ability of the hard disk to read data to a certain extent, and is an important parameter that affects the internal data transmission rate of the hard disk.
