SSD vs HDD

[Yelets]

My question is very simple. I want to ask by what aspects is a ssd better than a hdd. I want to know all the pros because I already know the cons (high price and low storage capacity). And all the reviews just dont tell everything. So please help

An SSD uses flash chips instead of a spinning platter to save data to the drive. While they are more expensive, they have much faster read and write times and are in a smaller form factor than a standard desktop hard drive,

ones fast small and expensive, the other is large cheap and slower. get a small ssd for your OS and then a 1tb hdd for everything else. the prices are dropping so its easier to get both

Benefits for a laptop would be less battery usage, reduced heat on your palms ( depending on where your hardrive is located on your laptop. ) as well as no moving parts so it will/may last longer.

SSDs are also limited by write life and data recovery options

While they are limited by write life, they have been shown to last drastically longer than advertised, and will still likely outlive any traditional hard drive, even if the HDD is put under a lesser workload.

I'll add to the others, SSD's are more durable than HDD's as they don't have any moving components.

Another advantage of SSDs these days is physical size.  The latest Ultrabook and ultra-portable form factors really can't accommodate hard drives.

 

Also, SSDs have now exceeded HDDs density-wise due to 3D flash.  Samsung is shipping a 15TB SSD.

Hey guys

 

Most pros and cons are pretty much listed already, but I wanted to add a couple more:
- As a con to SSD I must say that getting data off a failed SSD is nearly impossible due to the nature of storing it while recovering data  from a failed HDD is far easier both for end users and for data recovery companies, so in terms of data safety I would go with a HDD. 

 

- As a pro to SSDs, besides fast transfer speeds SSDs also have nearly instant access times which contributes to great responsiveness of the computer and boosts the overall performance of the system if you have the OS installed on it. Operations such as malware checks, booting and file search are dramatically improved.

Thanks for the replies!

To put numbers to the things people are saying I googled some benchmarks for mobile HDDs and SSDs. I tried to pick some of the more popular drive SKUs for each category. Obviously there are higher performance and lower performance drives in each. But they're not that much different. Also higher RPM HDDs aren't anywhere near as popular now that SSDs exist:

 

Desktop HDD (2TB WD Green)

Access time: 15ms

Read speed: 123MB/s

Write speed: 123MB/s

Power usage under load: 5.8W

Power usage at idle: 5.2W

 

Mobile HDD (1TB WD Blue)

Access time: 16ms

Read speed: 110MB/s

Write speed: 110MB/s

Power usage under load: 3W

Power usage at idle: 0.32W

 

SSD (250GB Samsung 850 Evo)

Access time: 0.04ms

Read speed: 536MB/s

Write speed: 391MB/s

Power usage under load: 2.2W

Power usage at idle: 0.03W
