Galaxy and hc550

Answer 1

If the Galaxy here referred to the Seagate Galaxy hard drive, there were many comparisons with the HC550 (Western Digital's hard drive):
1. ** Appearance **
- ** Front label **: The front label of Seagate Galaxy shows the capacity of the hard disk (such as 18T), and the series name (such as X18) below. It contains multiple models with the same capacity, as well as information such as model number, origin, production date, etc. The 18T capacity of Western Digital's HC550 is also in a prominent position. It belongs to the HC550 series and only has 18T and 16T capacity. It also has information such as model number, origin, production date, etc. The power supply information on both sides could not be used as a basis for selecting a power source.
- ** Side and back **: The Seagate Galaxy X18 has an additional hole in the middle compared to the HC550, and the bottom is the same. You need to pay attention to compatibility when installing the case. The compatibility of the two is not good for consumer-grade hard disk shelves.
2. ** In terms of parameters **
- ** Single disc size, number of discs and magnetic heads **: Both discs are 2T in size, with 9 discs and 18 magnetic heads. They are full-capacity discs. A non-full disk might reduce its capacity due to the bad area of the disk being shielded, but a full disk might not necessarily have a lower failure rate than a non-full disk.
- ** Speed **: Both are 7200 revolutions. After all, they are all enterprise hard drives.
- ** Caching **: Seagate Galaxy's Caching is 256mb, while the HC550's is 512mb. The size of the Caching depends on the manufacturer's technical route and strategy. You can't judge it based on the size alone.
- ** Stable parameters **: The average trouble-free time is 2.5 million hours, and the annual failure rate is 0.35%. These two indicators are among the top in their respective hard disk products. Consumer-grade products such as Cool Wolf Pro are far lower than them in these two indicators.
- ** Power supply requirements **: The maximum power supply requirement of the Galaxy X18 is 36.74W at the moment of starting, and the 4K random write can reach 34.35W at some moments. The maximum power supply requirement of the MC550 is 28.5W at the moment of running, and 26.8W at the moment of starting. The power consumption of the hard disk can be adjusted according to the maximum power consumption.
3. ** In terms of performance testing (hdtune-ordered and random performance testing)**
- ** Sequential Reading Test **: The maximum speed of the Seagate 18T is 270.4MB/s, and the maximum speed of the HC55018T is 278.1MB/s. Western Digital is 2.8% faster than Seagate.
- ** Average Reading Speed **: Seagate's reading speed is 207.5MB/s, while Western Digital's reading speed is 214.7MB/s. Western Digital leads by 3.5%.

If the Galaxy here referred to the Geely Galaxy E5, it had nothing to do with the HC550. The Geely Galaxy E5 was an A-class car with a length of 4615mm, a width of 1901mm, and a wheelbase of 2750mm. It had a large rear seat space. The rear seat could be adjusted by two gears. It had a panoramic sunroof that could be opened on 1.18 square meters. Some of the interior designs were convenient to use, such as small drawers, easy to take care of materials, and a small refrigerator. The rear seats could be folded to form a big bed. The interior was unique. It uses the Flyme auto, and the comfortable configuration includes the front seat ventilation heating massage, the main driver's pillow sound, the co-driver's leg support, etc.
