which one exactly is actually more mainstream?
and which brand makes better SSD atm?
 
SLC is more expensive and have lower capacity but its faster than MLC.

Dont buy MLC SSD with Micron controller - they are POS. Best MLC is from Intel.

 
SLC - faster write speeds natively, ridiculously expensive but in time it'll come down and be more affordable.

MLC - the older version of the technology, slow random write speeds but you can use some workarounds to alleviate the performance hit because of it. Far cheaper, obviously.

As for brands, I don't think that matters very much as most use the same components - there are only several Flash-RAM manufacturers on the planet so, even if it's a product sold by Company A, it was most likely one of the several Flash-RAM makers that built the chips inside it. Samsung tends to be the most popular as they're the largest Flash-RAM maker in the world... and I mean most popular in terms of the Flash-RAM chips, not specifically the actual SSD hardware itself.
 
how would i know if the MLC SSD has Micron controller?
because i do not find them in the data sheet

thanks for the info so far
still trying to look them up myself but SSD is just too new for me atm :confused:
 
MLCs have lower write speed and and SLC have higher write speeds... similar read speeds
 
MLC are actually newer, more complex technology than SLC.

SLC does have higher write speed, and can also withstand about 10x of the re-writes that MLC can (in other words, it lasts 10x longer).
MLC is cheaper to produce and available in much higher densities, but has higher power usage and higher latency.

JMicron controllers aren't bad if you have a RAID card with some onboard cache. Otherwise, it's probably better to buy something like the Intel X25-M which has its own onboard cache and custom controller.
 
alright then beside the write speed ( which i dunno how much faster ) and longer life time and cost
most importantly they both does not make any noise and doesnt produce much heat right?
because for the price of the SLC... itz really too much of a difference... from 3 times to 5 times more expensive... i was thinking maybe buy 2 MLC SSD or 1 MLC for now and 1 more in the future...
because the way i see it now that the MLC SSD is just better than any PATA/SATA HDD atm in terms of speed heat noise... plus it would be a semi workstation + storage computer
so i just need something fast to boot up the computer so when i do have to do work it just turn on and let me start working on it or search for whatever i need or something similar
 
If you need fast startup speed, start putting your machine into Standby or Hibernate, both are faster typically than any boot situation with any hard drive or SSD.

As for what solution is better, I'm not sure there is one right now. Considering the cost involved, you shouldn't look at SSD tech as "your savior" just because some devices in particular can perform as fast as some of the high end hard drives out there.

For the cost, and overall performance, and overall amount of storage space, the WD 640GB drives are still the cream of the crop these days. No, they're not the largest drives on the market with 1TB and 1.5TB drives out there, but as far as speed is concerned, they're basically second to the Velociraptors (I'm not getting into the other storage technologies like SCSI, Fiber Channel, etc - that stuff is irrelevant for general usage and almost every consumer situation).

I'd say go grab a WD 640GB AAKS or AALS drive and be happy. For the cost (roughly $75 or so, maybe with free shipping too, who knows) you'll be hard pressed to find anything that's considerably faster - and when you do find something considerably faster, get ready to pay through the nose for it.
