Solid state hard disc?

Question

i want to know about solid state hard disc.

as far as i know they don't have any motor or read write heads.so does that mean they are crash proof?

i mean i guess they wont gonna develop bad sector or so because they are not so sensitive as present hard disc are as they have motors and read write head/header.

Am i right or wrong?

somebody please enlighten me about this.

Answer 1

SSD are much more faster and less power hungry, it beats a regular HDD or maybe even a Raptor HDD, it has less thing working on the drive.

Answer 2

I'm not so sure if any hard disk is crash proof. But they are really small and really fast, their in most UMPC's (Ultra Mini Personal Computer).

Answer 3

No they aren't crash proof, just like USB drives and RAM, they will go bad eventually.  Like anything else made with 100s of differnt parts, anyone of them can go bad at anytime.

Not a matter of if, but when.

Solid state hard drives are not discs, so yes you are right when you say they do not have motors or read write heads.  Because of this, solid state drives have a smaller tendency to break down due to mechanical reasons.  This is also because solid state drives do not have any moving parts.  Solid state hard drives are very much like RAM, and in fact some are actually made from DRAM.  This is very similar to RAM, but is not what you want in a hard drive.  This is because while RAM/DRAM can be read and written extremely fast, during a power outage, your storage will be lost, as in gone for good.  This is why solid state hard drives are usually built with flash memory, which is similar to what flash drives use with one exception: they are hdd (hard disk drive) emulators, which means they can effectively take the place of an hdd.  THIS DOES NOT MEAN SOLID STATE HARD DRIVES ARE CRASH PROOF.  Like any human invention, it does not last forever.  Solid state hard discs have a number of "write cycles" they can complete before they fail, which basically means you can no longer write memory to your solid state drive.  Of course, this number of write cycles can be in the millions for well-built solid state hard drives, but it does not mean you can last on one solid state hard drive for the rest of your life.  Also, they cannot develop a bad sector like an hdd can, but yes they can stop working; unfortunately, they are also extremely expensive compared to hdd's.
