Upcoming technology, HDD replacement makes it


Recommended Posts

Having data stored in there SSD there is no need for superfetch. It can work as it's working in windows xp. It will get moved to memory when i say so, actually when i execute the program. It's gonna be fast. No need for creating overhead by moving data from ssd to ram.

You keep thinking that ;) there are situations where superfetch helps out drastically like high disk IO situations... as in database servers and high performance file servers

Saying something like "as HDD get faster and faster and eventually replace with something fast as your RAM" shows a serious inability to look at history and realize that things will play out as they always have:

Both will get faster. Your memory is still many orders of magnitude faster than your hard disk drive. Your computer can access is MUCH more directly than the hard drive (It doesn't have to weave its way through various controllers, which add latency and bottlenecks) and it always will be able to. That's simply the way it is.

This thread is stupid and a waste of space. Current trends show that MORE caching is the answer, not less.

Superfetch wont be useless even with faster hard drives(It just means when superfetch does load data from the hd it wont have to wait as long),the only way superfetch could become useless is when the storage medium is the same or faster speed as RAM is and not a mechanical device with moving parts but it could take years to do that but by then we will have 64GB memory as a standard instead of like 1-2GB today.

I just read this about 15 minutes ago and had to agree with one of the comments left by a poster on that story. HDD's are no where near dead because SSD's are still a ways off. The price per gigabyte isn't close to resonable yet.

Sure in some sense you could say HDD's technology may be out of date (not dead) but because it is still viable and will be for some time, SSD's price won't be coming down rapidly any time soon.

Even if you have a SSD drive, your computer still needs to load the program into RAM first before it can be run.

Superfetch loads the program into RAM before you use it. As a result if you have a SSD, loading that program into RAM will be faster than if you had a HDD.

But if you think about it, superfetch isn't some expensive program that you have to pay for. It's included in Vista and probably will be included in Windows 7. Vista came out at a time when HDDs vastly outnumber SSDs [and windows 7 will probably be the same story], and hence superfetch has a reason to exist and it works well.

So why are you making superfetch seem like a bad pointless thing?

i bet the superfetch technology will be updated in some way for windows 7 and superfetch is awesome,with xp's prefetcher it did what superfetch does but it does not put stuff back in by itself it has to be reread from the HDD meaning a slowdown but superfetch avoids that slowdown and it learns how you use the system unlike xp's prefetcher which would not learn anything.

jjrambo:it seems you do not or do not want to understand how superfetch or even how prefetch works,if memory is needed superfetch will allocate that memory and whatever else your apps may need it will do that as well and will keep putting stuff into memory as that will help keep all running smoothly.there are plenty of articles about it,once ssd's price comes way down then it will be worth it but with any new tech it will take time for the price to fall way down.

only if i could get one of those in my T60. I'd be happy but as of now just gotta stick to my regular HDDs. Maybe if i win the lotto :) I'll buy a 128GB version ($3,000!!!) and slap it in there and be more than happy. I only have a 100GB HDD now anyways and that's good enough for me.

A 64GB SSD used to cost $3000 six months ago. The prices are dropping but not fast enough. It'll be awhile before conventional HDDs are dead.

Not that long, especially for laptops. You can get a 32GB USB flash drive for as little as $50 now, and running a laptop on a couple of those is not out of the question.

Sure, something like a 500gb or 1tb HD will be a while, but doing something like having a small OS drive of 16gb and then the 500gb+ storage drives is not out of the question even now.

We are not talking about HDD. SSD is not conventional HDD. It's like your RAM with different purpose. There will be absolute no need for Software layer between RAM - SSD because data between RAM and SSD goes in measure of 186000 miles per seconds. I think some people have no clue what are they talking about here.

Once we get SSD, superfetch is absolutely pointless...

No you have no idea what you are talking about.

A SSD cannot be as fast as ram, and nor can it communicate with the ram as fast as you seem to think it can. Data between a HDD and RAM goes at the same speed as between a SSD and RAM. Just it can be read of the drive faster. It still has to go through a number of controllers before it even gets to the ram, and that slows it down.

Superfetch eliminates the need for the data to be read from the drive as it is already in the ram, and hence loads faster.

And yet again, Vista came out in 2007....lets assume that it stays for 2010. Do you think the vast majority of people out there [yes including businesses] would suddenly rush to get SSD drives for their computers just because its faster than HDD? For a good amount of time, lets say the next 5 years, HDD will be more prevalent than SSD and [according to your logic, which is wrong] superfetch still will be useful.

---

So to sum it up, superfetch won't be pointless if you have either a HDD or a SSD. Just the performance gain would be greater for a HDD than a SDD.

How the hell data gets into memory from HDD...magically using wireless technology lol?

Speaking of performance gain. I see no difference with or without Superfetch on my Raptor Raid 0 configuration. Not sure why most people are narrow minded. It's not like SSD will replace conventional HDD tomorrow. SSD will get improved and fast as RAM. Either way at some point Supefetch as midleware wont be necessary. Any software solution to overcome slowness of hardware has no future, never did in PC history and it will never have....end of story.

However, using hardware (RAM) to cache software (the OS and apps) does have a future, as RAM will be faster than HDD's/SSD's for the foreseeable future. We're already seeing RAM bandwidth in excess of 9GB/s. SSD's are nowhere close to that. Therefore, until SSD's close the gap (and whether they will is doubtful), RAM cache's will have a future.

SSD will get improved and fast as RAM

Sigh. This is simply not going to happen. As the data bus between the disk drive and the processor gets faster, the one between the processor and main memory (As well as main memory itself) is going to get even faster.

Do you think we're going to drop L1 and L2 cache because memory keeps getting faster? Of course not!

Data from the SSD/HDD gets into RAM IN EXACTLY THE SAME WAY.

Through I/O controllers....

And just because you have a nice big powerful computer, doesn't mean everyone does. If you can't seem to understand my post, stop trying to make yourself look intelligent.

The vast majority of people at the moment have HDDs, and the vast majority of people will continue having HDDs for 5 years at a minimum. Just because you don't notice any performance difference, doesn't mean others won't.

The other benefit of Superfetch is the hardrive doesn't have to be constantly spun up, and this is a power saving benefit for people with laptops. Windows loads, say word, IE, excel is loaded into memory. The hardrive can now be spun down and running at a very low power, compared to without superfetch. Without superfetch say the guy opened Word, then the drives spun down, and 20mins later he opened up Excel, the hardrives now have to spin up and excel will take longer to load [oh look a performance benefit also, who would have thought...] and this also wastes battery life. With superfetch, it learns what you use most and automatically loads into memory the instant your computer turns on...

---

According to your logic, why don't we just use Cache memory (which I believe is NAND?) for everything? It's the fastest possible...and yes even faster than RAM. Hell screw that, lets just make processors that have 1tb caches...there no need for ram...sadly thats not how computers work, maybe on your planet they do..but on Earth we're still way behind.

    • The Light of Life? We actually do glow till our Death, study finds by Sayan Sen Image by Rafael Rendon via Pexels A study by researchers at the University of Calgary has found that living organisms produce an extremely faint light known as ultraweak photon emission, and that this glow appears to drop significantly after death. The research was published in the Journal of Physical Chemistry in April 2025 and quickly drew widespread attention, leading to more than 200 news stories about the findings. Ultraweak photon emission (or UPE), sometimes called biophoton emission, refers to tiny amounts of light released by living cells as a result of normal biological activity. A photon is the basic particle of light, and researchers say every living system examined so far, including plants and animals, has been found to emit these photons. The glow is far too faint to be seen by the human eye. “I suppose it has a little to do with people being reminded of auras,” says Dr. Christoph Simon, PhD, one of the authors of the study and a professor in the Department of Physics and Astronomy in the Faculty of Science. “It is a fact that living beings glow. It’s a very weak glow, but it’s there and visible with very sensitive cameras.” According to the study, the light involved is extremely weak, ranging from 10 to 1,000 photons per square centimetre per second across a spectral range of 200 to 1,000 nanometres. For comparison, a nanometre is one-billionth of a metre and is commonly used to measure wavelengths of light. Detecting emissions at such low levels requires highly specialized equipment. To study the phenomenon, researchers used electron-multiplying charge-coupled device (EMCCD) and charge-coupled device (CCD) cameras. These imaging systems are designed to detect extremely small amounts of light, including individual photons, while minimizing background noise. The technology allowed researchers to capture signals that would otherwise be impossible to observe. The team worked with the Human Health Therapeutics Research Centre at the National Research Council of Canada (NRC) in Ottawa to examine photon emissions in mice. Researchers took two-hour exposure images of the animals before and after death and compared the results. “We saw that the level of light that they emit – this biophoton glow – is distinctly different between living and dead animals,” says Dr. Daniel Oblak, PhD, an associate professor in Physics and Astronomy and the corresponding author of the study. The images showed a clear decrease in photon emissions after death across the entire body of each mouse. According to the researchers, this provided direct evidence that living and dead tissue produce different levels of ultraweak photon emission. “It’s a very small amount and it’s, of course, very tricky to detect,” Oblak says. The study grew out of discussions between Simon, whose research interests include quantum biology, and Oblak, whose work focuses on detecting light for quantum communication experiments. Quantum biology is a field that explores whether processes described by quantum physics, which studies matter and energy at very small scales, may also play a role in living systems. “Since I work as a quantum physicist on light detection for quantum communication, I thought that experimentally we have a lot of the tools to be able to detect the light,” Oblak explains. The researchers also investigated UPE in plants and found that the light changed in response to stress. When plants were exposed to higher temperatures or physically injured, their photon emissions increased. Chemical treatments also affected the glow. Among the substances tested, the local anesthetic benzocaine produced the strongest emission response when applied to injured plant tissue. These findings suggest that ultraweak photon emission is closely linked to biochemical and metabolic activity inside living organisms. Metabolism refers to the chemical reactions that allow cells and organisms to stay alive and function. Because these reactions change when an organism experiences stress, injury or disease, researchers believe UPE may provide a way to monitor those changes. The researchers stress that the glow is a physical and biological phenomenon, not a metaphysical one. Oblak says more research is needed to understand exactly how the light is produced and what information it may reveal about the condition of living tissue. “We must understand what that is to figure out what’s happening,” he says. “If we can understand how that relates to certain influences on the body – stress, diseases – then that could be used as a diagnostic tool.” The researchers believe the technique could eventually help scientists study health and disease without invasive procedures. Because UPE can be measured without adding dyes, markers or labels, it may offer a way to monitor whether tissue is healthy, damaged or alive. In plants, it could help researchers better understand how organisms respond to injury, heat and other forms of stress. While the work is still in its early stages, the study demonstrates that ultraweak photon emission imaging can provide a non-invasive and label-free way to observe biological activity. Researchers say the approach could become a useful tool for studying vitality, stress responses and other important processes in both animals and plants.

    • Rufus 4.15.2393 Beta 2 by Razvan Serea Rufus is a small utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc. Despite its small size, Rufus provides everything you need! Oh, and Rufus is fast. For instance it's about twice as fast as UNetbootin, Universal USB Installer or Windows 7 USB download tool, on the creation of a Windows 7 USB installation drive from an ISO (with honorable mention to WiNToBootic for managing to keep up). It is also marginally faster on the creation of Linux bootable USBs from ISOs. A non-exhaustive list of Rufus supported ISOs is available here. It can be especially useful for cases where: you need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.) you need to work on a system that doesn't have an OS installed you need to flash a BIOS or other firmware from DOS you want to run a low-level utility Rufus 4.15.2393 Beta 2 changelog: Add RISC-V 64 support to UEFI:NTFS Improve the guards for using the "silent" option Improve the ability to cancel during write retries Improve progress reporting for compressed image extraction Fix unrestricted XML entity expansion and integer overflow in ezxml parser (courtesy of @esadowski4) [GHSA-55r2-34wg-8mv9] Fix "silent" Windows installation failing at 75% in most cases [#2960] Fix a crash during boot when using UEFI:NTFS on Snapdragon X based ARM64 platforms [#2934] Fix the first WUE option always being checked by default [#2965] Fix an infinite loop when using Windows ISOs that contain multiple WIMs Fix "Enable runtime UEFI media validation" checkbox not always being properly enabled Other WUE improvements/fixes for OneDrive removal and username validation (with thanks to @christian8641) [#2984, #2991] Download: Rufus 4.15 Beta 2 | 1.9 MB (Open Source) Links: Rufus Home Page | Project Page @GitHub | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
    • Tixati 3.43 by Razvan Serea Tixati is a free and easy to use BitTorrent client featuring detailed views of all seed, peer, and file transfer properties. Also included are powerful bandwidth charting and throttling capabilities, and a full DHT implementation. Tixati is one of the most advanced and flexible BitTorrent clients available. And unlike many other clients, Tixati contains NO SPYWARE, NO ADS, and NO GIMMICKS. Tixati portable version is meant to run on a USB flash drive or other portable media. It stores all its configuration files in the same folder as the executable binary files, and all file paths are stored in a format relative to the program executable folder. It is important you do not delete the "tixati_portable_mode.txt" file within the executables folder. This file is what triggers Tixati to run in portable mode. (The executable binaries are actually the same as the standard edition binaries.) When running the portable edition from a USB flash drive, especially one that is formatted in FAT16/FAT32, you may experience some lag when initially loading a new transfer. This is because initializing and allocating large files on flash-based media consumes a greater amount of time and resources compared to a conventional hard-drive. Tixati has the following features: detailed views of all aspects of the swarm, including peers, pieces, files, and trackers support for magnet links, so no need to download .torrent files if a simple magnet-link is available super-efficient peer choking/unchoking algorithms ensure the fastest downloads peer connection encryption for added security full DHT (Distributed Hash Table) implementation for trackerless torrents, including detailed message traffic graphs and customizable event logging advanced bandwidth charting of overall traffic and per-transfer traffic, with separate classification of protocol and file bytes, and with separate classification of outbound traffic for trading and seeding highly flexible bandwidth throttling, including trading/seeding proportion adjustment and adjustable priority for individual transfers and peers bitfield graphs that show the completeness of all downloaded files, what pieces other peers have available, and the health of the overall swarm customizable event logging for each download, and individual event logs for all peers within the swarm expert local file management functions which allow you to move files to a different partition even while downloading is still in progress 100% compatible with the BitTorrent protocol Windows and Linux-GTK native versions available Tixati 3.43 changelog: Several major DHT improvements Added
