M1330 harddrive...All have Free Fall sensor?

Do all the harddrives in the M1330's have the free fall sensor?
Does it make a difference?

 

Errr...I have the Samsung SSD on my M1330 and I'm not sure about whether it has the free fall sensor or not...

 

Without the same moving parts, I don't think the SSD drive needs free fall sensor. How do you like the drive? I wanted this, but at $900 it seems like a pricy upgrade. If I can buy 2 x 32mb cf cards or 32mb flash drives, for about $300, why would a 64gb be so much?

 

I just LOVE it. May be it doesn't relate, but the time needed to defrag and to scan for virus is much less than the 60GB traditional HDD that is on my desktop.

 

I don't think it is a good idea to defrag a flash drive. You don't gain because the access time is not slowed by physically moving heads to the next sector - and the extra writing to the drive shortens it's lifetime.

 

Naladas right in that the drive may be lessened from 149 to 148 years at its maximum potential or 49 to 48 years at its minimum tested calculation by several so far.

She is also right that there is negligible gain with the defrag, in that.... hmm how to explain this best....

Ok... the SSD has a sort of index and knows where to go for the info no matter what. There is no search involved. A typical HD does have to search for info and then wait and position the needle and so on. It is why the access time of the SSD is .1ms while the HD is 150 longer at about 15ms.

Still, there is no harm and, actually, because of the advanced wear leveling of most SSDs, defragmenting (if you want to call it that) is done automatically. Information is constantly moved and reorganized on a SSD , without your knowledge, as the SSDs controller ensures that each cell of an SSD wheres equally in comparison to the others. This is why there is so much less fragmentation and partially why an SSD can last so long. Much information on a HD remains there, in that spot from day one, defragmenting bit by bit as it is continually read from that spot. This is why you experience bad sectors in a HD whereas, you would never experience such in a SSD.

The scientific explanation is much more complicated but, suffice it to say, this was my best attempt at a laymens explanation.

 

Can anyone explain why if I can buy 2 x 32gb compactflash cards for about $300, a 64gb SSD drive should cost $900 - $1700? Don't they use the same NAND technology?

 

Nalada and flamenko, thanks for the info! repped
Maybe I should do more research on SSD...btw, does this mean that I can uninstall my AusLogics Disk Defrag?

 

I think just 7200RPM hard disks have the free fall sensor !

 

uhhh...same reasons why a 750GB and 1TB HDs have a MUCH higher price per GB than smaller drives....same size container, they need to fit more into the same size, so they have to shrink the memory, which takes more research and development, which is far from free.

That, plus, you always have to pay a premium for newer, rarer technologies...soon the 64GB will drop to the 'reasonable' pricepoint, and the newer 128GB will then have that 'new' huge premium over the others...and the cycle will continue to cover the costs of further R&D so that companies can keep pumping out new technologies for nerds like us

 

yes, you are correct, as of now, only the 7200RPM models have free-fall sensors...

 

Schmitty..Thanks for your reply. However 2 cf cards are much smaller than an SSD drive. Since CF drives are such old technology, and SSD drives are essentially the same technology in a different package, why the tremendous price difference?

 

Yes you can. hey lots o' articles in my sig block!

 

SSD & CF ???
