Why SSD is so expensive?

[Skela]

I am pretty amused about SSD drive prices. I have an external USB 3.0 HDD 1TB 2.5" SiliconPower for 60 EUR, which runs in theory exactly the same speed as SSD drive - about 6 Gb/s. But 1TB SSD drive costs more than 350 EUR. Can anyone explain me where I am wrong?

Thanks for reply!
Have a nice day

the read an write speeds of an ssd greatly exceed the speeds of a hdd

Your HDD doesn't run that fast. It is actually slower. The connections is capable of 6 Gb/s but you not utilising it at all. Only a SSD will utilise the 6 Gb/s.
If you haven't experience a SSD, you can't say it is the same speed.
1TB is expensive as manufacturing them is costly for now. 256GB has become cheaper now.

If you interested, there a Lightning deal on Amazon uk:

Nope. That's the interface speed, only one of the many bottlenecks.

Your HDD probably won't do over 100MB/s, while an SSD can easily do 500MB/s.

The difference is larger in random I/O than in sequential, too. An HDD will typicallly get somewhere around 75 IOPS, while an SSD can easily get tens of thousands.

A SSD is way faster than an HDD, that explain the price, but you have to consider that you should not use an SSD to write alot of stuff, as it does have a 'short' life span compared to an HDD, getting really slow as you fill it up or write/delete alot of data every day on it, causing it to die after X amount of data written. Should be used for the OS and a few demanding programs/games, that doesn't write too much data on it.

For a normal consumer, the lifespan of a HDD or a SSD will probably outlive you unless some physical damage occurs then its lifespan is reduced to nil.
If for a database center, SSD is probably not that ideal yet.

Thank You very much! Now i get it, as well as i don't need SSD as the main storage, but it would be nice to have about 256 Gb for system and 1 - 2 favorite apps/games.
