Read here, you may have a rough understanding of the Seagate st500lt012-1dg142. What advantages and disadvantages it has compared with other similar hard drives? The next part will talk about this topic.

Strengths and Weaknesses of Seagate ST500LT012-1DG142

The professional hard drive analysis website UserBenchmark concludes some results. The average benchmark of Seagate Momentus Thin st500lt012 1dg142 is 59.6% lower than the average hard drive benchmark.

It has an average consistency. The range of scores (95th - 5th percentile) for the Seagate Momentus Thin 5400.9 2.5" 500GB is 48.7%, which is a relatively wide range. That indicates the Seagate Momentus Thin 5400.9 2.5" 500GB performs inconsistently under varying actual conditions.

Its sequential mixed IO speed is only 38.2MB/s, while the 4k random write speed is 0.67MB/s. This is not good enough compared with other similar hard drives. In fact, this is a weakness of the drive. However, it works well in other aspects. For instance, its average 4k random mixed IO speed reaches 0.5MB/s and the average sequential read speed reaches 75.8MB/s.

Tip: You can perform a disk benchmark via MiniTool Partition Wizard. The Disk Benchmark feature of this software enables you to check the sequential speed of your disk with ease.

In fact, each hard drive has its own strengths and weaknesses. The key point is that what you need. For example, you need fast write/speed but you have to forgive other flaws of the drive. It is suggested that you make a comparison before purchasing one. After that, pick one that satisfies your demands at most with least flaws.
