Hi All,

I know SSD's are good for faster loading of O.S and applications, just wanted to know that does bad sectors occur in SSD's? the reason i am asking is, i format the drive very often atleast once in two weeks and the kids in the house dont know to shutdown properly, hence lot of improper shutdown, will replacing normal hard disk with SSD will solve the problem ?

thanks
Krishna
 
Re: Does bad sectors form in SSD's ?

I have never had such problems. the worst could happen is corrupted data. but it could be fixed by formatting i guess.

Have been disconnecting flash drives for a long time and also i didn't remember when did i shutdown pc last time.
 
SSD do not get bad sectors, as there are no moving parts in SSD. But it would be better to teach them how to shutdown properly, rather than getting a SSD.
 
As there are no physical sectors on a SSD, so there can't be bad sectors in them
PS: correct me if i am wrong
 
Each block in an SSD has an expected number of Read/Write cycles. For eg., the X25-M has each block rated at 10,000 read/write cycles. So yes an SSD can develop bad blocks.

However the firmware uses a few tricks to reduce this effect :

- write wear levelling by spreading out writes across blocks instead of hitting the same blocks

- a hidden spare area of blocks set aside on an SSD to be used when a block goes bad

In any case, I doubt a consumer SSD will help with improper shutdowns.

Some enterprise SSDs have a capacitor to help provide short term power to flush the buffers in case of a power cut, but obviously these aren't cheap.

Edit: On a side note, another option for your problem could be using a Live CD instead. There are some capable of booting off USB Flash drives too to speed up loading.
