Hitachi 2TB Hard Disk Evaluation
Hitachi Global Storage Technology (HGST) may be unfamiliar to many new DIYers, because the domestic hard disk market has long been occupied by Seagate, Maxtor, Western and other companies, while the knowledge of Hitachi hard disk appears more on laptop hard disk. But Hitachi's hard disk product line is very rich, from 3.5 inch desktop hard disk, 2.5 inch notebook hard disk, to enterprise hard disk, high-end server 10,000-turn hard disk, Hitachi is a giant storage company that can directly talk to Seagate in various fronts and hard disk industry, even the recent dynamic western data is only gradually close to them. With the acquisition of Blue Giant IBM eight years ago and the then technologically leading hard drive division, Hitachi's storage technology strength is beyond doubt.
At present, the hard disk brands that are relatively easy to buy in the domestic market are Hitachi besides Seagate and West Number, which makes Hitachi's hard disk famous as the king of performance-price ratio HDS721010KLA330-1TB hard disk in the previous period. The ultra-low price makes the storage of many users swell instantly. Now, due to the shortage, this Hitachi 1TB hard disk has retired from the throne of the king of cost-effective. However, you need not worry, Hitachi has launched a larger 2TB product - HDS722020ALA330. When it went on the market, the price of 1299 was much better than the price of 2TB green market in the west. Not only that, after only two months, the price of this 2TB product dropped another 200 yuan, and hit the market at the price of 1000 yuan, which shows that the price of performance is lower than that of the king again.
After Seagate and West Number, Hitachi finally launched its 2TB flagship hard disk with the largest capacity, and the speed is still the mainstream 7200 RPM, and this one. However, Hitachi's 2TB hard disk is a true 7200-turn mainstream 2TB hard disk; before that, Xishu first introduced 2TB hard disk, but only a low-speed green disk series products, followed by Seagate launched 5900 RPM LP series 2TB products, although both manufacturers later launched 7200 RPM 2TB products, but the output is very low enterprise-level RE4, black disk and SATA6Gb/s Barr. Acuda XT products.
As the last of the three major hard disk manufacturers to launch 2TB capacity hard disk Hitachi, the flagship hard disk HDS722020ALA330 unexpectedly did not use the latest single-disk 500GB technology, but used the exclusive five-disk packaging technology to achieve.
From the label data identification of hard disk, it can be seen that this is a 2TB capacity with the largest capacity of single hard disk at present. The main speed is 7200 RPM. It uses SATA 3Gb/s interface and its origin is Thailand.
From the groove on the back of the hard disk, the cavity of the motor part is one section higher than that of the PCB, which can not be seen on the packaged hard disk with 3 or 4 disks. if you want to partition recovery, you can use some data recovery software.
This Hitachi 2TB PCB is still in the formal mode. All the components on the circuit board are bare. Although the PCB of hard disks used to be packaged in this way, many of the current ways of purchasing computer hardware have been by e-mail. Some users still work by "naked running" directly without the hard disks being packed into the chassis (although not recommended, who is called DIY)? Exposure of components can easily cause damage in transportation and daily use. Here, we also strongly recommend Hitachi to use the most popular PCB flip mode as soon as possible.
From the hard disk cavity, it can be seen that Hitachi's 5D 2TB hard disk is not unreal. The location of the disk is almost full of the maximum thickness of the 3.5inch hard disk. It also brings Hitachi's unique 5D packaging technology into full play.
