Now, we are basically using solid-state drives. As the price of solid-state drive (SSD) continues to decrease, it is no longer difficult to buy a SSD to install the system or even store files. The advantage of mechanical hard disk seems to be that only data is more secure and files are not easy to lose. So I studied the current hot selling hard disk products, hoping to get whether the price gap between the two hard disks is really no longer obvious. < / P > < p > with the increasing game capacity and the volume of files and videos, many friends don’t consider products below 1TB when buying hard disks. Today, let’s study how many terabytes of mechanical hard disk can be bought for the money of 1TB ordinary solid-state disk? < / P > < p > the author first studies the standard price of 1TB SSD, which generally ranges from 600 yuan to 1600 yuan. The price gap between them is huge, and the performance gap is also obvious. < p > < p > in the past, 500GB was still the mainstream capacity of mechanical hard disk, and about 500GB solid-state hard disk was even more expensive, which could be regarded as a luxury in the computer case. Today, 500GB mechanical hard disk is hard to find in the market, almost all brands of mechanical hard disk are 1TB take-off. < / P > < p > the author has found the 500 GB version of the blue disk of western mathematics, which is familiar to everyone. Its speed is 7200 rpm, the size is 3.5 inches, and the cache size is 16MB. As the main force for a long time, the Western Digital Blue disk 500GB is used by many friends. Now the price of Jingdong is 155 yuan. < p > < p > at present, the price performance ratio of 1TB mechanical hard disk is higher than that of Toshiba P300 series. Its cache size is 64MB, and the current price is 279 yuan. If the cache size is relaxed to 32MB, there are mechanical hard disks with lower prices to choose from, but it will lose some performance and experience a little bit. < / P > < p > 2TB western mathematics blue disk is very cost-effective. It only costs 359 yuan per second. Do you feel friendly when you see familiar faces again? This hard disk has 256MB cache. However, seeing this huge cache capacity, we need to be clear that this is a SMR mechanical hard disk, and the speed will be slow when a large number of data are modified. < / P > < p > 3TB continue to choose Toshiba, 4tb Seagate cool fish is very cost-effective. The selling price of Toshiba P300 3TB version is 499 yuan, while that of Seagate cool fish 4tb version is 609 yuan. < / P > < p > skip the rare 5TB, the price of 6tb mechanical hard disk of each major brand is relatively close, basically floating around 1000 yuan. You can directly choose your favorite brand when purchasing. < / P > < p > fast forward, fast forward to 8tb. Generally speaking, ordinary individual users do not need such a large capacity, so they have entered the range of enterprise level products. So the price of hard disk is higher, and there is less choice. The price of the 8tb version of Seagate Galaxy exos enterprise hard disk is 1549 yuan, which is basically the price of a very advanced 1TB SSD. < / P > < p > as for the mechanical hard disk with larger capacity, it is no longer the price range of 1TB SSD. Therefore, the money to buy 1TB ordinary solid-state hard disk can roughly buy 4 to 8tb mechanical hard disk.
