Podrobneje glede mojega RAM drive principa

V tejle objavi pa malo bolj podrobno glede RAM-drajv/disk principa (zgoraj v naslovu sem raje uporabil kar ENG varianto besede), torej o tem, zakaj pri tem mojem računalniškem principu sploh gre. No, za začetek naj vam priporočim, da si, če ne drugega, prosim vsaj preletite nekaj postov v diskusiji “RAM drives and XP“: http://episteme.arstechnica.com/…/665008855731 na “Ars OpenForum” forumu (še linka do strani 1 in 2, moj posti se nahajo namreč na obeh, ampak predvsem glejte tiste na prvi), aja in hehe, spet, moj nick na tem forumu pa je shirker.

Torej, kot prvo je tu principles1.html stran na mojem glavnem izklučno z računalništvom povezanem domačem spletnem mestu (sicer je, kot lahko vidite, v angleškem jeziku) in članek oz. sekcija, katero sem zelo primerno naslovil “THE RAM-DRIVE/DISK PRINCIPLE” in kjer tudi napišem bistvo (glej tu takoj spodaj), skratka, da jaz ne uporabljam RAM-drajva/diska za pohitritev delovanja mojega PC-ja (čeprav je res to delno posledica tega), ampak bolj zato, da “rešim” moj trdi-disk pred nepotrebnim pisanjem na njega in mu s tem svaj malo podaljšam življensko dobo.

I use the so-called RAM-drive/disk program, particularly the QSoft‘s one from this site: http://www.ramdisk.tk (it consist of RAMDisk.sys, RAMDisk.dll and installation/info file ramdisk.inf); for details see the following thread on “Ars Technica” forums RAM drives and XP: icon-at.gif http://episteme.arstechnica.com/groupee/…/m/665008855731. I must stress at the very beginning I don’t use it in a matter of gaining a performance but to reduce hard-disk writes, i.e. I use it as a “host” for certain kinds of very heavy or “hard-disk intensive” operations. One of the main reasons for this (i.e. not havin any noticable impact on system performance) is that Windows already uses all unused the RAM as a “disk cache”, so you already get the RAM-drive alike access without doing anything. While of course I’ve heard for this kind of programs before, I’ve never actually bother to install and try/use one; while it is totally useful for files that are often written-to (because of the frequent hard-disk’s seeks), or for those that are frequently accessed, i.e. for the files that are only often read-from, however, many times these particular files mentioned in the above sentence (the ones that are often modified) are the ones that contain valuable data, so I think it all very thoroughly before moving them and start using them from the RAM-drive, i.e. in the end I don’t put those files on my RAM-drive in the first place. Hehe, in regard to “thinking it thoroughly” mentioned above; it actually ocurred once or twice that I couldn’t fell asleep because I knew that I haven’t yet thought it through (the “principle” of which files to use from RAM-drive and for which this is not clever thing to do). And of course, finally RAM-drives are ideal for any files/folders that are used as a temporary storage in general (files that are “meant” as a temporary storage), like various caches and various other temporary files and similar.

Potem je pa tu še stran software2.html stran na istem spletnem mestu in članek oz. sekcija “UNSORTED NON-SETUP RESIDENTS”, pod katero pa tudi omenim nekaj pomembnih, ali pa vsaj recimo temu relevantnih (torej s tem konkretnim mojim principom povezanih) stvari.

Another crucial “resident” is the so-called RAM-drive/disk program, particularly the QSoft‘s one from this: http://www.ramdisk.tk site; for details see the event entry dated “10.10.2005” on the “events4.html” page and the following threads on “Ars Technica” forums RAM drives and XP: icon-at.gif http://episteme.arstechnica.com/groupee/…/m/665008855731 and What’s the purpose of the “UsrClass.dat” file thread on “Ars Technica” forums: icon-at.gif http://episteme.arstechnica.com/eve/…/m/770008085731. Once more, I must say this yet one more time: I really totally love the whole idea of having a portion of RAM reserved for a drive that behaves as a hard-disk. Now I store all the Internet Explorer’s cached files on the RAM-drive, i.e. locations of its “Temporary Internet Files”, “Cookies” and “History” folders. But anyway, loosing these files (in case of a system crash) is not a problem at all, since its only a cache and these files are meant to be stored only temporary. Otherwise I can always copy them to some safe location before rebooting and then copy them back into the RAM-drive. Then I use it for other programs too; for instance the DNSKong programs I use constantly writes to its log-file and also IPs resolved to host-names to its presets.txt configuration file (it’s in a “hosts-file” style/format), then I also use RAM-drive for my Total Commander file-manager’s “tcthumbs.db” and “tcthumbs.idb” files (a thumbnail cache files), lately even for its .ini files (which are also often written to) and its treeinfo files “treeinfoC.wc“, “treeinfoD.wc“, “treeinfoE.wc“, “treeinfoF.wc” (for each drive/partition separately) and finally Bginfo’s “BGInfo.bmp” graphic; a walpaper with system related information. Therefore I am saving my hard-disk from a lot of additional but especially unnecessary stress, i.e. unnecessary writes to a hard-disk. I even got used to store one of the Firefox’s profiles in-there. Additionally I later even got the idea (and realised it already) to move the whole Start Menu directory-tree into the RAM-drive (except for “ProgramsStartup“, but I don’t use Programs branch anyway), since I know for sure that there are lots of hard-disk seeks when browsing through sub-menus; see the “principles1.html” page for even more details.

Skratka, če ste si prebrali ta dva teksta zgoraj, lahko vidite, da uporabljam RAMDisk od QSoft-a (to je sicer samo redirekt link), ki se drugače zares nahaja na tejle strani: http://users.compaqnet.be/…/…/ramdiskfree.htm. Je pa to res v bistvu drajver, ki je skoraj identičen tistmu Microsoft-ovemu “sample driver”, s tem, da ima nekaj dodatnih opcij kot npr. to, da lahko poljubno izbereš velikost samega RAM-drajva (in drive oz. po SLO “pogon”, kjer se bo nahajal), pa mislim, da je avtor naredil še nekaj drugih malih modifikacij!!

Drugače pa, zgoraj v tistih dveh “quotanih” tekstih omenjeni programi pa so kot prvo moj najljubši in daleč najbolj sposoben oz. dovršen FM-program z Total Commander (glej naprimer tudi tole objavo), potem je tam, kjer pišem o tem, zakaj bi mučil svoj trdi-disk s pisanjem na njega 6 MBBGInfo.bmp” slikice vsakič, ko bi hotel osvežiti sistemske informacije, omenjen tudi program BGInfo s “TechNet” dela spletnega mesta Windows Sysinternals (to je po novem, potem ko jih je kupil MS, torej včasih so bili samo Sysinternals; glej npr. tudi tole objavo) in pa še program DNSKong (za več o tem glej eno objavo pred to in pa predvsem tole objavo, ki je bajdvej sicer že zelo stara), programa WalCal pa sicer ne omenjam (še direktni download link in pa njegov screenshot), pa bi ga v bistvu najbrž tudi moral.

P.S. – Mogoče pa čisto za konec še link do nekega članka z naslovom “RAM disk | Windows Problem Solver“: http://winhlp.com/node/83 na katerega sem enkrat bolj kot ne po slučaju naletel, naj pa poudarim, da ta tekst v tem članku nikakor ni “avtoritativen” kar se tega področja tiče, ampak mi je pač padel na misel. No hehe, po pravici povedano sem imel ta link že pripravljen v mojem Sopca “to-do” fajlu.

    Spet sem objavi naknadno malenkost spremenil naslov (tokrat sicer takoj po tem, ko sem jo objavil), to pa sem naredil zato, ker je prej star/originalen naslov izgleda “grše”, ker se je nekam čudno prepolovi na dve vrstici, sedaj pa zavzema točno eno. Na srečo pa tokrat to ni čisto nič spremenilo URL-ja od objave; za več o tem o čem sploh govorim glej semle.
