Regardless of speed, price, noise, and heat, i heard that SSD has a write limitation compare to mechanical drive, meaning after certain amount of write execution, the drive is no longer good.

True?

It is new tech and there are many questions, my overriding one is bad chip?
so what happens if a chip goes bad like memory chips on 3d graphics cards often do? will you get corupted data (like you get corrupted image)? The positives out weigh any negitives and the chances are it will be upgraded before it dies anyway like most PC hardware…

Samsung launches its 1.8” 64GB flash replacement for portable hard drives

“Factoring wear leveling with commonly stated 1,000,000 write cycles can give you a pretty good estimate ... let’s say it really is only 100,000 write cycles and assume wear leveling is distributing writes perfectly evenly. That means you can write 6,400,000GB to this drive before it fails.

Now let’s assume you’re writing to the drive at 45MB/sec constantly. That means you could write to the drive constantly for 142,222,222 seconds or 4.5 years. I’d say that’s pretty damn good considering you’re going to want to take a break from all that writing and do a little reading once in a while.”

It has a limited number of write cycles, yes, but the life of an SSD will generally exceed the life of a standard mechanical hard drive, which has a limited motor duration. SSD also has something called “wear leveling” which balances the number of write cycles out over all the chips such that you don’t just kill one chip by constantly writing to it.

Also, both technologies (HDD AND SSD) “map out” defects so even if you do burn a few thousand bits out, you won’t even notice it. now, if an entire chip goes offline, you’ve got some problems, but this is equivalent to saying “what if only one of the platters dies on my HDD?” well, my friend, then you’re f**ked. Time to buy a new one in either case.

But your concerns seem to be about the reliability of SSD, which generally exceeds the reliability of regular HDD. It isn’t a new technology at all, really. SSD has been used in military/industrial applications for years. Because it came from this world, most of your concerns have already been dealt with.

i guess that a hard drive magnetic surface would theoretically have a higher life time than a SSD due to the wearing out effect of NAND memories or whatever they use in SSD drives.
But in any case a hard disk and especially a mobile harddisk is usually exposed to physical shock in everyday usage, and this is where the SSD scores, thousands of broken Ipod Harddisks and Notebook drives prove it :D, generally moving parts arent the top of it, if it comes to mobile usage

how about the storage limitation? If the data is not used for a long time (like few months), will the data get lost?  I plan to use my TR as my DVD player so planning to upgrade to SSD however I heard from a friend if the PC is not used for few months, the data will be all gone?

True?
