128GB fills up quickly. A 1TB 5400RPM 2.5" drive is $45-50 on pricewatch.

1TB HDDS are generally the most expensive. At such a low capacity it makes more sense to just get a 500GB SSD for $50. Alternatively if you really need the capacity of an HDD: for just $90 you can get a 3TB HDD. triple the capacity, less than double the price.

Edit: Apparently 3TB HDDs cost as low as 60€ nowadays...

Pricewatch is still around? I used it back in the early 2000s but forgot about it.

For EU prices also check https://geizhals.eu/ they got acquired by Heise Gruppe some years ago and are my goto-service for model comparison and extended filtering, also very useful outside EU. Haven't seen a comparable service yet for US with price trend and consistent feature tagging.

It'll cost the same but your 5400RPM drive will have about 30x more storage.

I think you meant 3x, 30x may have been true when SSDs were first brought to market.

I was talking about the price of a 128GB SSD vs. what you could get in an HDD for the same price. Not "what is the maximum size SSD available".

A cheap 128GB SSD would be around $40-50 while you can get 3TB HDDs for that price.

Both storage types will have comparable prices at 128GB, and their cost per GB will decrese at different rates as you increase storage capacity. It's not fair to compare pricing between different storage capacities across different storage types, that is why I have shared 1TB drives from the same vendor.

Also, a cheap 128GB SSD is way less than the price you have suggested, even a 120GB Kingston SSD is only $20.
