Well this explains one of my questions. I kind of figured the controllers had something to do with it. Thanks ZAP!
1 Question though, Does the chipset make a difference from p35 to p45 to p67? Only reason I ask is the OP is using a SSD on his P35
I would not discount that possibility.
quick search results
Aha! One of the three performance benefits of SSDs over HDDs is negated with the older chipset.
- high sequential performance
- low seek times
- high IOPS
Another reason for upgrading. I've always said that it is better to upgrade motherboards when upgrading a CPU (a few years down the line) to get newer technology.
This post got me thinking, why haven't HDD manufacturers implemented something like this? Surely it wouldn't be that costly to implement the extra logic on the controller and would be a nice security feature for consumers. You could securely erase a drive in a matter of seconds instead of hours to overwrite every sector. Of course just throwing away the key and generating a new one probably isn't as secure since the encryption could theoretically be brute forced, so government agencies or other institutions that are really paranoid would probably continue to wipe or destroy disks. Still would probably be a handy feature for many people, though, should provide more than enough data security for your average user.ssd's have encryption built in now so secure delete? not really necessary unless you are hiding from the government. once the key is destroyed the disk is rendered useless until someone cracks AES or figures out your key

.Give me one reason......... .
... if I don't care about bootup times (leave my computer powered up 24/7), if I don't care so much about app load times (keep my apps all running all the time), and am concerned about the ability to secure-delete an SSD, as well as the still-(IMHO)-exhorbitant price of SSDs?
I mean, I get along fine with my 6400AAKS drives, they are nice and snappy (for magnetic drives).
I installed two computers with SSDs so far, with Win7, and I honestly don't see the improvement. Maybe it's just me, I'm very patient, waiting short periods doesn't bother me. It didn't seem like it installed Win7 all that much faster than a non-SSD system.
I did have to wait several minutes for an SSD to delete the "Windows.old" folder on one machine though. Which honestly surprised me. I thought the whole point of an SSD was so that you would never have to wait on your HD.
So I guess I'm saying, I bought into the hype, bought some SSDs, and didn't see the improvements that I thought I would, so I've put off the idea of investing into an SSD for my personal rigs.
Best reason so far.Buying 1 from us will help pay my Christmas bonus? JK of course.
I relentlessly beat on it during school, work, play etc.
Is it just me or has virtual larry made this same thread before in the past?

SSD are awesome, if you dont want to pay for extra speed then dont.

Because the performance difference of using a software solution that encrypts the data is negligible for a HDD (a bit cpu overhead) while it's quite a problem for SF SSDs. So no reason to complicate the controller and make it more expensive (you need to add special purpose hardware that handles the en/decryption) and powerhungry in such a competive market.This post got me thinking, why haven't HDD manufacturers implemented something like this?

And really, trying to brute force a 128bit AES key or whatever SF is using right now, is completely out of question. As long as the implementation is fault free, the data is lost as soon as you delete the key. Or as an example: If you can try 500k keys every second it would take you about 2*10^25 years to try all possible combinations. Considering that the universe is about 13*10^9 years old, you better be extremely patient
And now we're all sitting here wondering whats on OP's drives.
Well I was thinking more like a decade or two from now when stuff like quantum computers may actually exist. People who are really paranoid may not want to leave encrypted data on their disk that could potentially be brute forced in the not too distant future. Unlikely scenario I suppose, but was just thinking out loud. Agencies who are that paranoid are probably going to destroy disks anyway instead of just wiping them.Because the performance difference of using a software solution that encrypts the data is negligible for a HDD (a bit cpu overhead) while it's quite a problem for SF SSDs.

PS: And yes I also remember we had this thread before, ah well, no reason to discuss the same thing thrice.
