Re: Intel 520 Series 120GB SandForce SSD
Before the data is written to the drive it is compressed, so that would not affect the quantity of writes. Of course it does. If the data is compressed 50% before it is written then potentially only 50% as many sectors need to be written. In the past storage manufacturers always assumed 50% compres...

Re: Intel 520 Series 120GB SandForce SSD
The Intel SSD in question is an X25. I can't remember where I found the 14TB figure now. Also keep in mind that Intel are using an SSD controller that does compression now, where as my older drive does not. They don't state what average level of compression they assume. I use SSDs for my main system...

Re: Intel 520 Series 120GB SandForce SSD
I just checked my laptop. The Intel tool reports 1.46TB of writes in around 5 months of moderate use.
I was surprised by how much data gets written at first. I used TrueCrypt on an older machine and it also keeps those stats, which is when I first noticed.

Re: Intel 520 Series 120GB SandForce SSD
26GB is nothing. Also don't forget that writes are amplified. My machine has 16GB of RAM so it isn't even page file thrashing.

Re: Intel 520 Series 120GB SandForce SSD
What worries me is the steadily reducing amount of spare capacity on SSDs. I have an older Intel SSD that is rated for a maximum of 14TB of writes. It ran out of spare capacity after about 18 months in my main computer (used mostly for web and software development). Had it replaced under warranty an...

Re: Finally a Super Quiet High-end Video Card?
If the 7950 is quiet at idle does it follow that the 7970 will be too? They are both the same chip but the 7970 has more available shaders, which should be in a low power "off" state when in 2D or light 3D modes.

Re: ADATA XPG SX910 128GB Solid State Drive
Would be nice if there were more info on how secure this drive is. Hardly any manufacturers talk about it.
Sandforce SSDs encrypt the data, but the problem is controlling the encryption key. Where is it stored? Is the ATA password used to generate it, or hashed in some way and combined with it?

Re: HP MicroServer
I discovered another flaw with the Microserver. The rear USB ports are too recessed to accept some USB devices. I have a wifi dongle and a USB to Serial converter that won't insert far enough into the slot to be detected. They work fine in the front USB sockets.

Re: HP MicroServer
The temperature sensor is working, the fan kicks in at 100% and then drops down to around 1100 RPM and stays there.
There is no way that even the PSU fan on its own is anywhere near the 22dB HP claimed.

Re: HP MicroServer
I took the DC PSU out of my Atom system which idles at 22W. In the Microserver it idles at 28W in the BIOS with no HDDs (so obviously can't boot up). The HDD makes about 5-6W difference so we can say about 34W with it, and then drop down 8-10W once booted due to power saving in Windows. As it happen...

Most (all?) UK models seem to be battery powered. I'm wondering why that is because Japanese and US meters are not, and it seems obvious to use the mains power. My guess is that it is safety related. I am tempted to try attaching a plug-in PSU in place of the batteries in one of mine to see what hap...

Re: Intel Sandy Bridge Extreme: Core i7-3960X Processor
Well there is a hint in the price tag. It suggests that their yields are low. In that light it makes perfect sense to write off two of six cores if your process can barely turn out that many. It will be interesting to see what the 4 core version using the same silicone will cost.

I was really disappointed too because I like AMD gear.

Re: OCZ RevoDrive 120GB PCI Express SSD
Any kind of non-TRIM garbage collection is limited by the fact that the SSD can't tell what data is in use and what can be dumped. Only the PC which can read the filesystem knows that. Mike, maybe you should run some more tests to determine the effects of this. Basically fill the drive with lots of ...

Interesting! The ADE7755 outputs a square wave with frequency proportional to power consumption. Do the meters also show line voltage? In that case there must be other hardware measuring that.
