Okay, just a quick question, I already know all the basics behind these two storage systems, the question I have, is why does it appear some people are rabid about SSDs? Am I the only one who notices this? Like there are some people that will automatically say the HDD is causing problems and need to be replaced with a SSD, or they treat the HDD as the devil, and will recommend a SSD over any other component for overall improvement. Is SSD really as great as some people make it out to be?

Some people are easily impressed. Yes, the SSD is faster than the HDD, but the HDD is more dependable. And SSDs have a finite time they can be written to. HDD don't have an infinite life, but they generally will outlast a SSD in daily use. Personally, I have a SSD in every PC I own or have recently owned. I won't be w/o one now. But unless you are always in a hurry, the HDD is still relevant. And at the dropping prices now, Terabytes are cheap.

It's the best thing since any sort of sliced pastry you can think of. It's MUCH faster, more reliable, no moving parts. I honestly couldn't go back from using an SSD from this point.

In terms of speed there is no comparison; SSDs are much faster.

In terms of noise there is no comparison; SSDs are completely silent.

In terms of price, it's whether or not you're willing to pay $2/1 GB (approximately), whereas a HDD costs about $.07/1 GB.

You will get more perofrmance gain from an SSD drive then from any other upgrade even more memory. While the SSD has tripple the read/write speeds of HDD its huge gain is in its almost 0 seek time, while the HDD has to spin to file 1, then spin to a diffeent part of the drive for file 2, etc, etc.

Now as to why people would "treat a HDD as the devil" it is either perception or in that specific instance the HDD was the issue. The HDD still has its place for large storage and will it will be a while before SSD can meet HDD in storage size or espically in $ per GB. There are plenty of legitimate failures for hard drives and an SSD is not nearly as fragile as a HDD but it does not make a HDD automatic garbage. Some people once they hear Y is better then X they imediatly just trash X even if X does a fine job doing X but just not as good as Y in situations; look at peoples opinions on phones, computers, TVs, cars, almost anyting.

For any consumer to reach the write-end of an SSD is extremely unlikely. With this test Tech Report is doing here http://techreport.com/review/26523/the-ssd-endurance-experiment-casualties-on-the-way-to-a-petabyte you could write 100GB of data to the disk per day and it would take 13 years to reach the 500TB "half-life" of a lot of drives. I don't see many 13 year old hard drives still puttering around with heavy daily read/writes. Not saying there aren't any but the chances of a HDD failure over an SSD failure, especially from use, you're coming out waaaaay on top with an SSD.

Reliability - SSD vs HDD

Current consumer grade SSDs are proving to be more reliable than current HDD's.
Write level of hundreds of GB per day, for years, before they start to fail. Hundreds of GB per day is waaaaay outside a typical use case.

Yes, price per GB is more than HDD. But personally, I would not build a new main use PC without one as the boot + application drive.

You know the song "You don't know what you got till it's gone... " well after you have used SSDs for OS and applications this will be blatantly obvious to you. Go to any computer store & try one out ... you will notice the difference!!!

SSD endurance tests have gone to and beyond 1 petabyte of write actions. On regular consumer grade SSD's.
The equivalent of hundreds of GB writes, per day, for several years.

For real world comparison, my 24/7 Kingston boot drive is around 5TB total writes in ~2 years of use.
My SanDisk secondary SSD is around 4TB total writes in that same time period.


EDIT: change "hundreds of TB writes, per day" to "hundreds of GB writes, per day"
The concept still stands.
