> The Crucial drive has no problem doing at least 100MB/sec for the entire capacity of the drive, if that's your thing.
That's quite slow to be frank, as stated slower than an HDD and that's quite disappointing for an unsuspecting consumer who does want to transfer larger files.
P.S. see the footnote where after 1 hour or about 300 GB the transfer speed start to collapse entirely.
> Consider the 240GB ADATA in the article. It can write over 400MB/sec for over 150 seconds before throttling kicks in. That's 1/4 of the entire drive.

It's not specifically about the small 120/240 GB SSDs, the 1TB Crucial shows that larger drives exhibit the same problem. If your SSD is 1TB or 2TB, that 50GB transfer doesn't feel so enormous anymore as compared to drive size.
I'm going to agree that most people won't have a use case for transferring large files. I've actually repurposed the Kingston as an OS drive for my lab server.
But the key objective of my blog post is to show that cheap SSDs exhibit this behaviour in the first place. Many people are not aware / don't know. They can still decide that it's no problem for them. But for some, it will be an issue.
This is not about the smal <$20 SSDs, but about the concept of cheap SSDS often having terrible sustained write speeds, regardless of capacity. And many review sites don't highlight this issue or actually show when the throttling kicks in.
