Re: What the people are asking for + a few others.

I am not sure whether you are making a general comment, or referring to a specific case. But do you think that in general a Ramdisk is safer than a deferred write cache? I'm generally referring to using write-back caching (deferred writes), but specifically when using RAM/L1. No its no worse than a...

Re: repopulate/proactive level 1 cache

I would like the option of "infinite latency", even if it is not repopulated after a reboot. My data is all distributed computing work that just overwrites old data with new data having the same set of file names, and I normally don't need to flush it at all. You have a very interesting w...

Re: Windows 7 Double Caching

Well Superfetch does 3 distinct things 1) Watches the files touched during boot from startup services and apps. It makes sure these are on the disk to be sequentially read in - fastest for spinning HDDs. 2) Watches the files touched when a particular applications launches (dlls, binaries etc). Same ...

Re: What the people are asking for + a few others.

I mean Intel does it just fine with their RST program that just came out with. Thanks for reminding me. I was so excited when this feature was announced... and so disappointed when I found out that the new chipset was a requirement. :( But Intel actually doesn't handle this either. They have 2 mode...

Re: What the people are asking for + a few others.

I was aware of the write issues actually - I'm ignoring write caching. I've always assumed FC was ignoring flushes to get great write performance. I don't think I would trust defer writes. Not sure I follow what you mean here. Indexing isn't really used all that much unless you do a lot of searches....

Re: What the people are asking for + a few others.

I think the log/journal you're talking about is the Access timestamps. Nope. Timestamps are per file, stored in the MFT I believe. The NTFS journal should be a better choice. "The change journal is much more efficient than time stamps or file notifications for determining changes in a particul...

Re: What the people are asking for + a few others.

I was only half serious about the Filesystem part. That would simply be the cleanest solution - caching built right in. Obviously the work involved would mostly outweigh the gains. Personally I am OK with not-100% solutions at home as long as the error cases are fully disclosed. Agreed. For removabl...

Re: Windows 7 Double Caching

I find your use of the term 'Windows 7 caching' somewhat confusing. Also, I'm not sure what you intend to disable. 1) Superfetch (introduced in Vista) is a prefetcher. It tries to learn your habits on what programs are used, and files touched, so that when you try to run your most commonly used prog...

Re: What the people are asking for + a few others.

The only danger to this is that if data was changed in "off line mode" then FC might return the wrong data. I question what they mean by that along side that fact when and why data would change in "off line mode," "offline mode" likely just refers to any time a disk is...

Re: What the people are asking for + a few others.

1) Persistent L2. Complete this feature alone and you've got my money. Obviously not so easy as you're a layer on top of the filesystem which can be changed 'offline' without FC knowledge. I'm crossing my fingers. 3) Pool Dynamic Priority Percent Base L1. 4) Set L2 to Read, Write, or R/W, and give ...
