ssd's

Post by hawkeye »

i am curious as to ssd's(solid state drives).

1.can they be partitioned?
2.is it true you can only rewrite over them a certain number of times?
3.can they be defragged like a normal drive?


i ask because i am thinking of installing one in my laptop and dual booting xp pro 64 bit with kubuntu linux.

I think it should be easy enough to gather the info from these links.

1. Yes.
2. Yes, but the number is large and some filesystem types can be configured to reduce overall write fatigue.
3. Yes, but with modern Linux filesystem type,s manually initiated defragging is unnecessary.

Wait a few months if you can; SSDs are getting cheaper all the time.

1. yes.

2. no

3. yes but there is no point since any "sector" can be accessed instantly without regard to where it is on the SSD device.

SSD's advantage is that you have very quick access time and they are very quiet. They can do everything a normal HDD can do and with the new ones they can do it better. Some of the older Transcend SSD's were terrible and much slower than a normal HDD (although faster access times). The new Samsung drives though are fantastic ... albeit very expensive. SSD's are a godsend when it comes to EGTB's ... their incredibly fast access times reduce dramatically the EGTB performance hit on engines. At the moment the price is not yet reasonable ... but soon I would expect 512 GB drives to be cheap and within reach of everyone. 2 of those drives in RAID 0 would make the ultimate 6 piece EGTB system. Personally I think that for EGTB's USB drives still make more sense. You can get a fast 32GB EGTB drive for around $85 ... that is more than enough for 5 piece EGTB's ... the rest of the 6 pieces still has to go on HDD, but the cost is reasonable.

...
Each cell can be rewrite only 10 000 to 100 000 times.

That's already a lot ... and some internal system can move the "weared out" area to safe area ...
