does Mean Time Between Failures (MTBF) = lifespan?

QUOTE(everling @ Aug 21 2010, 06:35 PM) The lifespan of an SSD really isn't an issue for most home users. At 5,000 write cycles for an 80GB SSD, in a perfect use, it will accept 400,000 GB of writes or 219 GB of writes a day for 5 years. Even taking the write amplification factor, which TRIM partly mitigates, into consideration, you should still be able to write 100 GB a day (20 GB more than capacity) for five years before failure. It is no question that SSD is realiable nowadays. Actually I think from a consumer point of view, we are more interested in the reliability of SSD as a whole. (whole thing, include the connectors, circuit board.) instead of the SSD chip itself. To lose your SSD to wear and tear, you would have to fill up your SSD every single day for five years! Wear and tear is not a real problem.   if they are soo certain about all that. Why cant they just give 5 years warranty. Anyway, I am still sticking to HDD, unless SSD start selling price as low as RM100 like HDD. *regardless of capacity. I am fine with 20GB @ RM100.

Video that I found on YouTube shows the comparison of Windows 7 start-up time with boot drive using the SSD and HDD..
I've been thinking about replacing the HDD boot drive on my PC with SSD.. But SSD's price is quite expensive, makes me have to think again.. Ouch..  |

I'd buy the cheapest ringgt/GB SSD with a good controller. Kingston's SSDNow V Series 128 GB comes to mind. Intel's are also another good set of SSDs. The greater performance from SandForce's controllers isn't that great once you have any decent SSD and OCZ SSDs has a huge price premium. |

You mean the Kingston SSD?
It's RM 899 at Cycom. Not as fast as Intel's or OCZ's, but will easily crush any HDD and it has a nice capacity for the price. I've been using mine for months already on WinXP for my laptop and am pretty pleased.  I suppose it might still be a rather attractive product at this point in time, despite Intel's Gen 3 SSDs drawing closer. With Kingston's 128 GB capacity and cost, it won't be as big a regret when compared to buying an expensive 120GB OCZ Agility SSD (RM 1399). Update: The Kingston is available at RM 860 at PC Zone.

SSD Decoder Ring - an SSD comparison guide (Rev 3.0) to find out the model number to check which controllers the SSD is using. Intels are safe, Indilinx are safe, Sandforce has awesome benchmarks, avoid anything with the old JMicron 602s. Some older Kingston SSDs are using the terrible 602s.

Nice SSD performance, but price quite expensive., really hope the price will drop some more so that can get 2 for RAID0.

If its for games, there's less value in getting an SSD RAID setup. A single SSD alone will feel like better than RAIDed HDDs and games have a tendency to be CPU or GPU bottlenecked.

Well 0.5 USD per Gigabtye or not. It is unlikely I will buy SSD unless their minimum price is priced close to HDD price now. ~RM100-200
Which gonna take a while. |
