SSD vs. HDD??

[BronyPie]

Whats the Difference?

[AlwaysFSX]

Man Googling is hard.

 

 

[Shiv78]

SSD = usually costs more per GB, but get MUCH more pperformance (ideal for boot drive, important apps and sometimes games) Limited reads/writes and so needs to be replaced in maybe 5-10 years depending on SSD and usage

 

HDD = cheaper per GB, but slower. Better for mass storage (music, videos, pictures) and doesn't fail for a very, very long time.

SSDs are much more reliable than hdds.

[pagani123]

ssd are fast but expensive and its hard to recover storage off of them if they die, hdd are less expensive but slower and are better for documents that you dont need to access or want to loose in case of a failure.

But, aside from hardware failure, good quality HDDs last longer and data is easier to recover if they fail versus SSDs, which WILL fail eventually, due to a limited life cycle.

I seriously doubt a hard drive could take nearly the same amount of read/writes an SSD of equal quality can endure. The hard drive is mechanical, thus its mechanical arm is prone to wearing out.

But very few people are writing tons of data to their drives(and even if your writing 24/7 it will still last a few years)

 

Most people will drop their laptops, which will kill many more hdds than ssds.

The amount of data you could write 24/7 to an SSD is far greater than the amount of data you can write to a hard drive 24/7.

 

Laptops often turn off the hard drive momentarily upon moving them, nowadays.

SO other than failure, hdds don't fail. 

 

You just said hdds fail. SSDs are more reliabe http://www.zdnet.com/article/ssd-reliability-in-the-real-world-googles-experience/

nah man, flash memory - SSDs have a limited number of R/W IOs before the cell is useless. HDDs have no limit to the number of times they can be read or written. that being said, many high-end hard drives run 24/7/365 for YEARS with no loss of performance or capacity. 

And as somebody said earlier, depending upon how the drive failed, you can get data back from a HDD - not possible with a SSD

The mechanical parts of the hard drive can wear out, too, so yeah, they do have a limit. Also, flash memory is limited to the number of times a block can be erased/written (also known as program-erase cycles), where reading has little effect, if any.

You can say the same exact thing about SSDs.

Why aren't you backing up your data, then? External hard drives aren't expensive at all, and neither is cloud storage. Data recovery should be the last thing you should rely on, because that can cost way more money than just backing up your data.

Hi there

 

As the guys pointed out, there's a lot of information on the Internet regarding this. @AlwaysFSX  posted a very good video with an explanation so I'd check that.

 

There are a few main differences between the Hard Disk Drive and the Solid State Drive:

- Price: HDDs currently cost far less per GB and thus are preferred for massive and secondary non-demanding storage purposes.

- Moving parts: SSDs don't have any moving parts and thus produce far less heat and no vibrations or sounds and are smaller and lighter and are preferred for mobile computers and smaller builds. 

- Principle: HDD store data on a magnetic platter and read/write from/to it via a moving arm with a read/write head on it and use the magnetic forces to do this while SSDs store data on NAND cells located on chips on a small motherboard and use the electrical forces to work. 

- Performance: Generally, SSDs, due to the nature of the way they store data, have significantly higher performance compared to HDDs. as they have nearly instant access and seek times and perform much faster when it comes to read/write speeds (depending on the bus they are using (SATA or PCI)).

 

Having one over the other isn't always the best option so the choice would depend on the purpose the drive will serve.

 

Let me know if you have any questions!

The issue is that Googling is not difficult, but the forum is here so people can ask questions and get help from people without effectively repercussions. By stating that one can just Google it, you are potentially turning them off to the forum, and making them become part of another community that actually helped them with their issue, stalling the growth of this community.

 

And of course, when someone does use Google, they can find this as a resource, giving them more answers and more options, and perhaps more confidence in their answer.

ssds are way faster, but hdds are cheaper and can store more data

1) agreed, but in an intensive environment like a deduplicating SAN node, SSDs are a TERRIBLE idea

2) I can't say the same - most vendors who make storage solutions with SSDs won't even touch a full-SSD array - they will do a tiered deployment that allows for data to be moved off of the SSDs onto a more resilient media...HDDs.

3) I never said anything about not backing up my data...and when I do back up, it isnt to SSDs - it's to a RAID 1 array and offsite RAID 6 array. and those are just my personal backup repositories.

 

all of that being said, on the whole, HDDs are more resilient than SSDs when it comes to actually using the device. if you are constantly reading/writing to a disk, you will destroy an SSD. HDDs wear out, but that is not a guarantee - a SSD reaching its R/W limit is a guarantee.

Why don't i just throw my real life example to the mix.

 

owns a 15 year old 500mb hdd and it still runs flawlessly in my current computer.

 

3 samsung 850 evo died on me after 4/3 years of use.

 

 wala all answers solved?

No. It's not solved at all. Hard drives fail every day, and what you experienced is known as "anecdotal." You are also comparing 15 year old tech(or older) to modern-day tech.

Back to OP's OP - 

A Solid State Drive or SSD is a storage device made up of flash storage chips (much like those found in a flash drive) although interfaced to the computer with a SATA or SAS interface (for higher performance than the USB flash drive mentioned earlier)

 

A Hard Disk Drive or HDD is a storage device that consists of a series of metal "platters" (the "disk" in HDD) that have tiny sections that can be magnetized to store the data.

SSDs can also interface through M.2 or PCIe.

As for the lifespan of HDD vs SSD 

 

 

HDDs wear out over time. SSDs wear out over writes.

 

Your HDD doesn't really care how much you write into it, it will wear out over time almost the same as if you were barely writing anything in it or just reading. It can just keep on writing and writing 24/7. Great for mass storage and server applications.

 

SSDs can only be written a certain amount before they start to wear down and go bad. So for uses where you will write tons of data onto them 24/7 they will die fast. But we are talking hundreds of GB per day, nothing regular consumers need to worry about.

I have to disagree with this. An idling hard drive will likely last longer than one that is constantly reading/writing because the arm is moving around much more with a drive under stress. A drive under strain will see the most wear-and-tear.

Can't agree more with this! 

 

Reading/writing causes more wear on a drive compared to plane idling. if a drive is most often on idle it would eventually enter safe mode and will spin down. On the other hand, constant read/write will not only wear the actuator arm, but it will also cause the spinning parts to work more and will put the rest of the electronic parts such as the PCB under more load.

[carsonwen]

Well yea I guess I didn't quite word that well. My point is that with SSD you know that writes will eventually kill it. With an HDD it may wear more under load but there is no hard cap to how much you can write onto it, it may survive a long time it may not.
