I don't know if my situation is out of the ordinary, but I recently got an 840 Pro 256 GB drive to use as my C: drive (for Windows 7). I've managed to get the Write Amplification Factor down to 'only' 4.5 or so.
Using your numbers above (a 120 GB drive for 1,000 PE Cycles and 100 GB a day)...
Just an update. I managed to get my WAF (for the last cycle) down to about 4.6 from about 6.6. I discovered that a hardware monitor program (Aquasuite) had been configured to record temperature info (etc.) every 10 seconds.
Turning this off got me down to 4.6, but I was still hoping for...
I checked through "OS optimization" if that's what you mean. Indexing and prefetch are disabled. Write Cache buffer is enabled.

Not doing any explicit DB stuff. Aside from the initial load, I'm...

Defrag is/was already off.

Maybe. Maybe...
Hi;
I recently replaced my old 160 GB Intel X-25M SSD with a new larger Samsung 840 Pro 256 GB drive. I'm using this as my C: drive for Windows 7.
It's early days yet, but it seems like I'm seeing a higher Wear rate on the Samsung than I was seeing on the old Intel.
After about...
> The scenario you described, you should be safe enabling AHCI.
FWIW, I just added an Intel X25-M 160 GB SSD to my system (Asus Ramage Formula X48). Before I started I was set up as IDE. I found and followed a recommendation on how to switch to AHCI mode (for Vista).
The claim was that...

Just to clarify a bit more, this seems to be true when you backup and...

It seems that the answer is 'It depends'...
I just got a 160 GB G2 X25-M SSD myself. It sounds like you want to make an actual image 'copy' to the external drive.
I haven't done this...

I was under the impression that the X38 was being billed as a replacement for the 975X, which does appear to support ECC.
Crucial lists DDR2 ECC modules for an ASUS 975X P5W...
I haven't seen anywhere that states if the the X38 will/won't support ECC memory. All the P35 motherboards spec's I've looked at seem to be for non-ECC memory.
So, should I assume that Intel (or the Motherboard manufacturers) have abandoned ECC memory for this generation of chipset...
My system conforms with at least items 2,3 and 5 above.
Also, I use memtest86+ (Available at Memtest86+) since it seems to be a little more up to date then plain old memtest86 (last time I checked).
For those who might not be familiar with these tools, I came across...
I don't know if you are still interested in finding what part of your current system is causing the problem or not, but you could try using Prime95 and 'underclocking' as a way to try and isolate the weak link.
You could first try and run Prime95's 'torture test' for up to 12-24 hours the...
