SP 2.5" SSD 512GB Bought to replace a 7-year old 512GB HHD. Instantly improved the bootup time from 1~2 minutes to 10 seconds. The other app startup is also super fast, especially from the 2nd bootup from SSD and on. Had a minor problem with the partitions on the original HHD. I have two main partitions on HHD mapped to drive C: and X:. I just wanted to clone drive C: and exclude X: to SSD. Wth NTI Echo 2019 coming the SSD, I've tried all 3 options on the C: partition, but after cloned C: to SSD, there's a partition of 210GB (which correspond to partition X: on the HHD) on SSD that I cannot map it to a drive, nor I can access it from anywhere. Eventually I have to download the free version of another partition management tool named "MiniTool Partition Wizard" to merger this blocked 210GB partition into the primary C: partition. All in all, the SSD is great; absolutely worth to buy. The next thing is wait and see how long it can last.
