SSD will eventually fail though, just the rate is unjustified at the moment cause SSD just being adopted in recent years, < 5 years, HDD has been for quite sometimes.

Reliability? There's no such thing as reliability, otherwise those makers will build 1 time then close business (100% guarantee??). Which is why redundancy is being used, this is reliability and backup, yes backup is important as well.

Dirt cheap drive now allows users to RAID without spending more so, you want reliability? RAID + Backup then, since it's "dirt cheap" that you can afford more.

At first, I used to think SSD has no moving part, it should be significant reliable than HDD, and this is many people perception as well, I reckon

But to my disappointment, after reading many complaint about SSD, and search through, SSD also subjected to failure as well despite no moving parts in it.
http://www.tomshardware.com/reviews/ssd-re...ate,2923-3.html

SSD failure % can be on par with HDD as well.

Just HDD being mass use around, that's why we see many complaint about dead HDD.
For eg. There are 500 million of HDD in the market, a 1% failure means we see 5 million dead HDD, and complaints around.
While there may be only 1 million of SSD, even at failure rate of 2%, we only see 20k dead SSD.

5 million dead HDD vs 20k SSD, the figure look huge difference, but it doesn't say SSD is more reliable or not.

Oh my! Nowadays HDD are not trustworthy as a matter of fact when its gonna fail you sooner or later. I think when SSD was introduced, HDD are going damn cheap and cheaper until its robustness or Quality Control (QC) acts like nobody business. I am not saiding that i will give up HDD but i am sad that their inspection are getting worse and worse if the price of HDD is getting dirt cheap nowadays. So, by the time HDD is around a few bucks imagine the reliability of it. Sign!

HDD become cheap, doesn't mean QC also must become "cheap".

So those product that sold in few buck which is cheap in cost, so QC also no bother to check?
Unrelated.

HDD is not going to be sold at few buck, (can keep on dream for it, but won't happen), same like just like processor, ram and other hardware.
Manufacturers will opt to obsolete the product, once it get too cheap that not viable to produce in term of cost.

Also expensive doesn't mean QC is top notch, and consumer won't get a defective product.

And the reason for those failures are... surprise; firmware issues.
Sandforce controllers has been notorious for their BSODs, it's not on a hardware layer either it is more towards the firmware. So, techcnically it has nothing to do with the hardware.

Intel can create reliable firmware for their Sandforce based SSDs (330 and 520).

That article is over a year old, and over the last year the SSD market and industry has changed considerably.

That being said, we do need another 2-3 years to tell if SSDs are as reliable as HDDs or not. Intel's first generation X-25 SSDs are still running strong today.

Whether firmware or not, or hardware itself or firmware, once the computer BSODs, cannot boot up again, be it HDD or SSD even physical is not damaged, as a consumer, we facing the same consequence, a dead computer that cannot function. smile.gif

Reliability is about we can continously using the computer without any problem/glitch.


Added on July 18, 2012, 10:52 pmYes, it is premature to judge on SSD.

Still think SSD tech is far more maturing, especially on firmware issue.

Saw those experience suddenly SSD cannot function due to firmware issue in the SSD thread or a sudden SSD malfunction, my company still decide to use HDD for the latest purchase of office computer.

Fyi, my company office still got computer using a 80GB HDD (which is largest at that time), still functioning strong.

It doesn't matter which manufacturer it was. Very few 3.5" HDDs will survive a proper fall, and it is still chancy even with 2.5" HDDs. When handling HDDs, it is best that you treat them like glass, eggs or any other fragile goods, because they are in fact fragile.

As for repairs, the original manufacturers won't do it for you. For them, it is far cheaper to give you a brand new HDD. For you, it is also far cheaper and quicker to accept a brand new HDD. If you do want to attempt to retrieve the data, you'll need to fork out a lot of money, wait a long while, and still face the possibility of some partially recoverable data or absolutely no recoverable data.

Moving on from this disaster, it would be cheaper to buy two or more HDDs and duplicate your data between the two.

Just a discussion, a "fall down" or "dropped" HDD, shouldn't be the data on the disk itself is still intact? or electromagnetism on the disk itself (that storing the data) will be loss on the disk due to the fall?

As I reckon, when the HDD is not in operation (when carried along), a dropped could means damage the mechanical part of the HDD, as head is parked during idle (non-operation), there shouldn't be any scratches on the disk.

SSD reliability is still a myth. This is a new technology, it has yet to be proven >10yrs. HDD is definitely capable to run 5-10yrs without problems. I have 10 of them over 5yrs old, 2 out of the 10 is already >10yrs old.

SSD? they still need to prove themselves first b4 only to claim more reliable than HDD. SSD more reliable in theory only, in real world will be diff story, dont be so quick to jump into marketing gimmick tongue.gif

I say stick to HDD until SSD price get lower. Thanks to Windows 8, now ur boot time isnt an issue anymore.  tongue.gif

I tested on an very old 80GB WD sata 1 HDD. win8 boot <30 secs

I have the same taught that SSD should be very reliable since there is no mechanical part, but after I read this article, I only realised SSD may be as super reliable than I taught previous.
Yes, it may be better, but SSD is not without failure as well.

http://www.tomshardware.com/reviews/ssd-re...ate,2923-3.html

From the stat posted on SSD failure rate, the failure rate is about just slight better with HDD or a notch better than HDD.

talking about importancy, I think even if they give me life time warranty and it keep spoil in few years time will keep on destroying our data. It's bad.

If worry about data, the always and better solution is backup or RAID.

hi. may I know is there anyone try putting a WD RED 3tb into Hotway 3.5" USB3.0 K32-SU3 external enclosure? I've tried the combination in lowyat(the technician there help me to assemble) but it only manage to detect 2tb..the technician have no idea what to do... luckily can refund.. then i contact the Hotway support and he told me need to change the GPT format... but I am skeptical to go buy and test it myself.. especially the drive is for my Athlon X2 PC usage... thank you for your replies...

Yes, you need to format in GPT to see the 3TB.
2TB is the limitation of MBR format.
