lol yes because adding a -A to the end of the part number will get people to realize what they are getting. How many of you even look at the part number when buying something? I mean like on newegg all i would look at is the name and the specs.
This situation is the result of several interlocking variables. As process technology shrinks, gate-length also shrinks.The smaller the gate-length, the greater the degree of leakage. This means that 25nm devices will not (statistically speaking) hold data as long as 34nm devices. I think the current 25nm retention length is around a year. That sounds fine for most things, but there's no reason a properly stored HDD wouldn't still be able to access archived information ten years from now.
The more a cell "leaks", the harder it is for the switch to tell the difference between a 1 and a 0. This can be compensated for by increasing the size of the charge that's used to provide the "1". Problem is, the stronger the charge, the greater the wear on the memory cell.
These factors, in aggregate, are why SSDs based on Flash memory won't ever completely replace hard drives. There's no magic solution that keeps prices flowing ever-downward while simultaneously delivering performance, data longevity, and drive longevity.
To tell you the truth Inspector I always look at the part number. Of course I have also been employed as a professional warranty technician back in the day, so that was already in my conscience by default (part details), and I have been an online purchaser of equipment for a long time as well, so I know there are differences even within a single part series, and those are usually found with the part number.
Of course another thing is used to be (no I did not have to walk to school uphill in the snow) it was the only way to know you were even getting the right thing, at least in many cases. So I by default pay attention.
The thing I am kind of wondering here is I thought OCZ is using nm chips that were lower than 25nm measurement chips on there 3 series drives, with sata3/6. They seem to not be using either on this drive build so I am automatically assuming these will be a lost model build before they even hit the market! I am also wondering why they(OCZ) had no difficulty in making super high performance drives, with more size as well, but Corsair seems to be even though they to are working with Sandforce on there drives.
If retention of data has dropped to only a year as Joel says, then for me we have already reached the point of diminishing returns with this tech. There are files on my hard drive that are way older than a year.Not too mention that SSDs are still way out of my price range considering I can get at least 1 TB for the price of a 80 GB SSD.
Does the data on a SSD get refreshed like RAM? If so, the situation might not be so bad, otherwise I would be looking at reinstalling the OS once a year or so yes?
My mistake for not clarifying. So long as the drive is powered, it retains data. The problem manifests itself if you use SSDs for long-term storage. I own several hard drives that I've used to make substantial backup archives, for example. The other day I had occasion to need data from 2001 that I'd neglected to transfer as I updated systems.
I was able to pull the WD800JB drive I was using then and load the data no problem, even though I hadn't used that drive in at least 8 years. You can't do that with a 25nm SSD at present; I'm not sure if a 34nm drive would hold data that long, either. Even if we assume it would, the comments on diminishing returns still apply.
For typical consumers, a year is more than enough time at this point. My general understanding is that this becomes a major issue at 22nm and possibly a show-stopper at 16nm. I'm fairly confident someone will figure out a fix before then, but it's still a good example of why SSDs won't be able to match HDD prices for a very long time--if ever. Flash is a good SSD solution for now, but I think we'll see companies pursuing other methods of solid-state storage over the next ten years.
Thanks for the clarification, and I will remember to use traditional hard drives for long term storage.
