Even "resources-hungry" programs will get enough memory. The concepts behind `Future Drive Accelerator' ********************************************** `Future Drive Accelerator' is a disk-cache program. A cache buffers all data which is written or read from the drive (hard disks, floppy disks, Compact-Disk, removable disk, ZIP...). If requested data is already in the cache, it doesn't need to be loaded from the slow disk. So far nothing new! Memory is, as we all know, always short. So you better think twice before you give it to programs. No matter how you set it up, you can never make it suitable for all programs. One program runs (thanks to the cache) faster than ever before, another one stops working (due to the lack of RAM). With all other cache programs, you had to adjust the memory usage. Of course, the more memory a cache can use, the faster it will work. So with old cache programs the memory usage had been set quite high, but because other programs stopped working this was stopped rather quickly. Now the cache is commonly set to an average size, so that all "memory-eating" programs run. Or you always had to change the cache-size manually to fit the current situation. But this is not a very satisfactory solution. And this is where `Future Drive Accelerator' comes in. `*The whole free memory*', whose size is changing all the time, `*is used as cache.*' With this technique, an `Amiga' with a 68030 50Mhz processor and 16 MByte FastMemory (Blizzard IV) averages a *factor 4* speed up. See Benchmarks. Write accesses are buffered, and later, while *writing back* to the drive, the head is moved from the highest to the lowest address. Another improvement is built-in for people who use exchangable media like disks, CDs, MagnetOptical-disks and ZIPs. When inserting the media again, the still filled cache is used. The media doesn't need to be accessed again. Who used a lot of dos-buffers? (1) for the file system, you can now even `save' this memory. Not to mention that you `*help protecting the environment*'. The motor and the electronics of the drive is used less and thus, energy is saved. => the *nuclear power plants* can be shutted down earlier. You should also keep in mind that the *hardware* wears out less. ---------- Footnotes ---------- (1) A dos-buffer requires (per default) a half KiloByte. What is required to use `Future Drive Accelerator'? *************************************************** `Future Drive Accelerator' needs at least: "AmigaOS" 2.0 or better. "2 Megabyte memory", more memory is recommended. Additionally, the following software is supported: "DiskSafe" (http://de.aminet.net/pub/aminet/disk/salv/DiskSafe.lha) After a reset or system crash, the cache will be written back before restarting the system. Example installation for `s:Startup-Sequence': DiskSafe DF1: DF0: HD0: Store: Font: HD2: HD3: HD4: ... REBOOT QUICKKEY WAITVERIFY VERIFYREQ LOGFILE=Store:T/DiskSafe.log IGNORE If this shouldn't work, try adding `RESETKEY'. "CopyMemQuicker" See Speed up. "FileSystems", "Devices" See Features. What speed improvements can be achieved with `Future Drive Accelerator'? ************************************************************************ * Copies 850KB in *35 seconds* from hard to floppy disk, this equals the speed of formatting. This is possible because, minimizes the overall seek time required to read or write data from or to disk. Outstanding I/O requests are ordered such that they can all be performed "*with one sweep*" of the disk head assembly, from the highest to the lowest disk address (Elevator seeking). * *23 MB/s* while reading, (SysInfo V3.23) instead of 7 MB/s without cache, with an Amiga and following equiment: Zorro III, CyberStorm MKIII, 060/PPC 604 150Mhz, UltraWide SCSI HD, 64 MB FastMemory, CopyMemQuick 40+. * The booting can get twice as fast if there are a lot of small files to load and many files reside in the `WBStartup' directory. * Faster access to directories from Workbench. * Amiga MC68030 50MHz, 16MB FastMemory. - IDE-HardDisk (tested with `DiskSpeed') (1) read *6.8 times* faster. write *8.1 times* faster. - DD-FloppyDisk (tested with `DiskSpeed') read *488.0 times* faster. write *997.6 times* faster. - Copying from one partition to another. 44 Dirs, 561 Files = 2.3MB Size c:Copy MUI: ASWAP:MUI ALL CLONE QUIET Dos 457 Dos-Buffers 46 secs 253999 micros FDA 7 Dos-Buffers 11 secs 196642 micros (*4.13 times faster*) * Amiga PPC604 233MHz MC68060 50MHz, 96MB FastMemory. - IDE-HardDisk (tested with `DiskSpeed') read *19.5 times* faster. write *20.4 times* faster. - SCSI-HardDisk (tested with `DiskSpeed') read *3.8 times* faster. write *3.5 times* faster. ---------- Footnotes ---------- (1) DiskSpeed Reference: 262144 byte, MEMF_FAST, LONG-aligned buffer. Compatibility, Features of `Future Drive Accelerator' ***************************************************** * Accelerates all kind of media e.g.*: Harddisk-, Floppy-, Compact-, ZIP, MagnetOptical- or SyQuest-drives, almost like a RamDrive. * Uses the `*free memory*' as `*cache*' , the program reacts automatically on changes in memory resources, so that you will always get the maximum speed for your drives. Even "resources-hungry" programs will get enough memory. * Minimizes the overall seek time required to read or write data from or to disk. Outstanding I/O requests are ordered such that they can all be performed "*with one sweep*" of the disk head assembly, from the highest to the lowest disk address (Elevator seeking). * Gentle, parallel reading and writing in Multitasking. * Smart-Power-Technologie: Minimizes the number of disk-accesses. * SmartCache: Read-ahead of blocks. * When disks are removed, the cache is only removed if necessary. When disks are re-inserted, the cache will be used again. * No fragmentation of memory. (Opposite to DynamiCache.) * Can possibly save memory, because dos-buffers are not required anymore. * Power-LED flashes when accessing cache. * Verify is as fast as in a copy-program, because data is verified in the background while writing. (the processor isn't used much while writing anyway). * If `DiskSafe' is installed, the cache will be written before a reset or system-crash restarts the computer. See Requirements. * Supports `DiskExpander' (http://de.aminet.net/pub/aminet/util/pack/epu14.lha), `Virtual-Memory-Manger (VMM)', `XFH' (http://de.aminet.net/pub/aminet/util/pack/XFH.lha) `temporal files' and `World-Wide-Web browsers'. * Supported devices: (probably all - scsi (http://www.amiga.de/files/index.html), 2nd.scsi, NewStyleDevice, atapi (http://de.aminet.net/pub/aminet/disk/misc/IDEfix97.lha), cybscsi, - trackdisk, floppy (http://de.aminet.net/pub/aminet/disk/misc/floppy43.lha), diskspare (http://de.aminet.net/pub/aminet/disk/misc/Diskspr3.lha), hackdisk (http://de.aminet.net/pub/aminet/disk/misc/NewHackdisk.lha), mfm.device ((C)CrossDOS), messydisk (http://de.aminet.net/pub/aminet/misc/emu/msh-156.lha), - fmsdisk (http://de.aminet.net/pub/aminet/disk/misc/fmsdisk.lha), - xpkdisk (http://de.aminet.net/pub/aminet/util/pack/xpkDisk37_8c.lha), - cd. * Supported FileSystems: (All knownn) - FastFileSystem(FFS), V44.5 (http://de.aminet.net/pub/aminet/disk/misc/ffstd64.lha) V43.20 (ftp://ftp.amiga.com/pub/) - ProfiFileSystem1+2(PFS) (http://de.aminet.net/pub/aminet/disk/misc/pfs95.lha), HomePage (http://www.greed.nl) - AmiFileSafe(AFS) (http://de.aminet.net/pub/aminet/biz/demo/afsdemo159.lha), - SmartFileSystem(SFS) (http://www.xs4all.nl/~hjohn/SFS/), - MessyFileSystem(MSD) (http://de.aminet.net/pub/aminet/misc/emu/msh-156.lha), - CrossDOSFileSystem(MSD) ((C)CrossDOS), - Berkeley (NetBSD LinUX) Fast FileSystem (BFFS UNI\02) (http://de.aminet.net/pub/aminet/misc/emu/bffs1.3.lha). and compatible, furthermore all MultiUser-"clones". * Supports FileSystems with a variable block-size. * Supports harddisks with a capacity of 4 GigaByte or more. * Protects partitions beyond the 4 GigaByte "barrier" from faulty accesses. * Is the fastest cache program. Accelerates harddisks by the *factor 2*-*20*, floppy disks by the *factor 2*-*997*. History V2.0 17-Dec-99 * Fixed, hanging of mfm.device (CrossDos) v40.9 and fd.device (XFileSystem v2.14 ) v42.86; because they use SendIO() without WaitIO(). This are also the case for the hanging bug of FDAPref. * Fixed, capacity-change detection for XFileSystem v2.17 * trackdisk.device OS 3.0 doesn't work with ½ trax and format-command, and doesn't reply a error value. The update-task uses now the write-command, but now the clear-command doesn't work for verify, which compare the trax while writing the next track. There is current no ideal solution for this problem. Perhaps using format-command for removeable medias, and 'size of track` does allow only a multiple of default size (5632 bytes). Any suggestions are welcome. New known bugs: The preferences calculate sometimes unreal values of 'Size of Track' for trackdisk.device, will be fixed soon. FAQ addition: * Please, don't install QuietTD from DiskSpare, i don't know why it hangs. * Please, don't use fd.device v42.86 from XFileSystem v2.14 together with "verify", use instead mfm.device it works. XFileSystem v2.16 do something but not bugfree. Copyright addition: Registration move to new user is free of charge. History V1.8 09-Nov-99 * Fixed, "write-Async" not 100% working timer, and detect perhaps an OS3.0 quick-flag (CheckIO) bug. * Added, PFS against FDA+FFS benchmark. History V1.6 30-Sep-99 * Recognize capacity-change of removeable-madias. I.e.
