Year for 2007 Hard disk Storage It can be said to be a flat year. But it is quiet in this year, 3.5-inch hard drive has finally broken through TB mark. Already three companies have introduced a 1TB-capacity 3.5-inch hard drives. Seagate although not in time lead, but the 1TB capacity of more mature products, and also introduced two levels of products for different applications, can be said to Accumulate. Also, because business users on the growing demand for storage performance, Seagate recently launched high-end enterprise applications for the new SAS hard drive - CheetahNS. Performance Test We conducted a routine performance testing products, testing instruments are primarily used I / OMeter and HD-Tach. But for CheetaNS, we did not test for HD-Tach-related, because as a product for enterprise applications, HD-Tach test results did not make much sense. In addition, we use FlukeTi20 Thermal Imager On the Barracuda 7200.11 and BarracudaES2 operating temperature tested; and selected a 5 disc capacity of 10 head of products for the 1TB the same temperature testing. Test results from the point of view, this 3 products are quite good performance: CheetahNS called powerful performance; designed for near-line storage and hygiene BarracudaES2 shown in the stability test is satisfied; Barracuda 7200.11 While In the I / OMeter test performance is not stable, but its overall performance was satisfactory, after all, it is only a desktop-oriented products, such as stability and performance to meet the needs of general users, and users should be more concerned about its capacity. Although the temperature test as power test so intuitive, but a hard drive to operate at full load the temperature is precisely the power The most direct expression. Therefore, a IR Picture than a set of data to the visual. All thermal imaging pictures are hard at full capacity (for I / OMeter test) during the shooting. Which, Barracuda7200.11 temperature of 39 degrees Celsius full load; Barracuda 7200ES2 full temperature of 37.2 degrees Celsius; and our fully loaded for comparison 1TB hard drive temperature is 42.2 degrees Celsius. From the picture we see the color far BarracudaES2 contrast the color of the hard disk light. Can say, with second-generation perpendicular recording technology, Barracuda 7200.11 and BarracudaES2, in power, temperature control of very good terms, thanks in density and internal disc simplified mechanical structure. Of course, BarracudaES2 it, PowerTrim the role technology can not be overlooked. Sorry about that, since the CheetahNS using 2U Frame Type Server And can not take to the Cheetah NS work at full load temperature performance. Summary This 3 Seagate's products represent the maximum current drive product design and manufacturing standards. Clear line of demarcation, for different application modes of product positioning, whether individuals or business users can easily make a choice. For individual users, Barracuda7200.11 is a very good choice, 1TB capacity of the higher prices will not prevent users from selecting it; For enterprise-class users, BarracudaES2 or CheetahNS can well meet their storage needs, established Massive near-line storage can be used BarracudaES2; structures Network Server platform, you can choose Cheetah NS, which is owned BarracudaES2 high cost, low capital investment allows users to use mass storage space.
