i need a recommend to get a ssd. - Page 3

post #21 of 97

Actually, there are couple of ways to lengthen the life expectancy of the flash chips soldered on SSD boards. 1. Reassign pagefile to a hard drive. 2. Cool it as much as possible (write cycle is usually affected by junction temperature as mentioned in several flash IC datasheet). 3. Get a DRAM SSD for pagefile, as well (pointing to #1, although more expensive but relevant). 4. Buy a larger bank of RAMs and be careful about how much programs you open (not everyone cares, BTW).
not trying to be rude here, but all underlined comments are totally wrong.

1.) pagefile access is practically MADE for SSD. 1 write per 40 reads. Intel and microsoft both recommend leaving the page file on the SSD. i do not use pagefile, but that is another matter entirely.

2.) SSDs generate negligible heat, this is a huge selling point of them. they have no moving parts. this is the most ridiculous statement ive read on SSDs in a very long time.

3.) ridiculous and redundant. leave pagefile on SSD

4.) this is totally unnecessary and makes absolutely no sense.

i cant help but think that dr. mario is just joking around, these statements are so ridiculously off-base. hilarious

Well, what about the CPU in SSD? They generate about 1 W heat - use it for a while, then feel it, you will know. Same with regular HDD. Also, they still generate heat as of transistor leakage. No joke. Don't believe me? Go and find the datasheet for the flash IC and CPU inside the SSD.

Yes, but SSDs also can stand redicolous temp, the heat it generates isn't going to harm it at all.

Well, yes. It's true: they can stand up to 105 C or a bit higher until the CPU in SSD shuts itself down to save its ass. The only thing that will be impacted by heat are the flash chips' rewrite cycle endurance. I have seen enough in datasheet saying the colder the ICs are cooled, the more rewrite cycle it can hold before finally wearing off to its death. 300,000 rewrites for MLC-NAND was quoted in some SSD datasheet, but it can do 720k or more depending on brand and temperature.

Lastly, the most recent flash ICs don't suffer transistor leakages as much as their older generation "family member" of the certain MLC-NAND product lines as they are of 25nm (25 nanometer) size, with modified Hi-k Metal Gate transistor fabrication processes. In other word, they consumes less current when reading the contents on "floating-gate" transistor cell banks. And, with that, it could also be able to hold the charges much longer, as the leakage is being kept to minimum.

Mario, you are so off base it is unreal. The only SSDs that i have ever used that get any type of appreciable heat generation are Sandisk drives that i used for this review:

http://thessdreview.com/raid-enterpr...-and-protocol/

these drives are for servers and 6,800 dollars each. no one has these lying around.

however, note these reviews where i used 8 x 256 gb C300 and also 8 x OWC SSDs in the other one.
http://thessdreview.com/our-reviews/...-and-protocol/

http://thessdreview.com/our-reviews/...r-card-review/

http://thessdreview.com/our-reviews/...ron-c300-ssds/

right now i am testing 8 WildFire SSDs. here is a pic of the review of an enclosure that i used them in:

http://thessdreview.com/raid-enterpr...-and-protocol/


i have a slight understanding of what i am talking about. The heat generated by a 1 WATT processor is nothing.

50nm nand is rated for 10000 P/E Ratios.
30nm is 5000 P/E
and 25nm (the current gen) is 2000 P/E ratios

the numbers you are spouting are nonsense.

Okay, then Computurd, do an experiment to prove me wrong. I have no more to comment.

LOL why do i need to do an experiment? shouldnt you be doing it?
what experiment would you wish me to do?
post #28 of 97
It's sad to see so much nonsense being spread about SSDs today.

If I listened to all the crap I read about SSDs, I'd be scared for my life because according to the crap I read today, one would think they're ticking time bombs ready to explode.

I my SSD.

To the OP, get an Crucial M4 128GB on newegg for less than $220 and you'll love it.
