Results of attempts to use various flash media as drives in Macs. Other media types can be included (ie IDE on SCSI adapters, etc.)

Please copy and paste the blank line at the bottom, then enter your data above it. That way everyone will have a template they can use.

If you have a full page of test results with speeds etc, please link it, for now.

Please try to use consistent names for models of Mac, adapters, media, software etc, as this will help with table sorting.

Notes

  1. In device table, SCSI Probe, System Profiler, Drive Setup, on desktop - anywhere really
  2. As shown in Apple System Profiler or other hardware diagnostic
  3. unless shown, version matches OS
  4. Due to reliability concerns, the use of consumer-grade flash as virtual memory or swap space is debated
  5. 5.0 5.1 Will try in a 16 bit slot and see if it helps (ie in a 1400)
  6. ASP v3.0.1: Model:TXN,PCI1210-00 Vendor:104c Device:ac1e
  7. 7.0 7.1 Bad blocks, many failed installs, attempted repairs. One apparently successful install: volume still not available in Startup Disk. Later; seen in SD, selected, system no found on reboot; reverts to OS X boot which crashes partway through. reset-nvram required to restore normal OS X boot. Reformatted with Drive Setup under OS 9.2.2, zero all data. Drive now appears clean, but results are the same. A blessed system folder, but not selectable from OS 9 Startup Disk CP. It is selectable from OS X Startup Disk prefpane, but on reboot results are as before. My provisional conclusion is that this particular card had some bad blocks to begin with, but that this is not the ultimate problem; for unknown reasons PCMCIA ATA Flash is not bootable.
  8. ASP v2.6.3 PC Card 2 ID = 0 Hard drive Removable media: No Vendor: Seagate Revision number: 06.12.06 Product ID: Flash 7.4.0
  9. 9.0 9.1 9.2 Adtron SDDS Cardpak™ 3.5" PCMCIA card reader for SCSI bus.
  10. 10.0 10.1 10.2 10.3 10.4 10.5 Disk Utility v. 10.5.6 ships with Mac OS X 10.4.11. To format the storage media with a recent version of Disk Utility provides smooth operation when data is exchanged between old an new systems by swapping media.
  11. 11.0 11.1 11.2 Data obtained with Apple System Profiler v. 1.3.2. Apple System Profiler v. 2.6.3 crashes on a Power Book 1400 with Mac OS 9.2.2, but v. 1.3.2 is quite usable.
  12. 12.0 12.1 To prevent auto eject of the PCMCIA card on shutdown/restart install Mac OS 8.1 directly onto the CF card, without driver update. Copy desired System version to the card, afterwards.
  13. Type: harddisk, Bus: ATA Bus, ID: 0, Capacity: 122.2 MB, Vendor: Hitachi XX.V.3.3.0.0, Product ID: -, Revision: Rev. 0.00, Connection: ATA, Removable: N (in fact the medium IS marked as removable at boot time), Partitions: 1
  14. In this setup I use the CF card exclusively for VM, to round out the inbuilt amount of DRAM. For this use it does not matter if the CF card is recognised properly at boot time as long as an appropriate driver is loaded during startup.
  15. VM works, but drive is not cold bootable as it is not accepted by ROM driver. Hot boot after loading appropriate driver works, however, verified with Mac OS 8.1 install CD (version for PowerMac G3 beige desktop).
  16. 16.0 16.1 Delock PCMCIA PC-Card CardReader, 16-Bit PC-Card, 33 in 1 CardReader
  17. Type: PC Card, Bus: PC Card, ID: 0, Capacity: 3,7 GB, Vendor: Memory Card Adapter, Product ID: -, Revision: 67281306, Connection: ATA, Removable: Y, Partitions: 1
  18. 18.0 18.1 18.2 Stratos™ CF PowerMonster (2.5" CF-SCSI adapter, built to replace PowerBook SCSI drives, available with adapter to fit 50 pin IDC connectors when used instead of a 3.5" SCSI drive.
  19. Boot time with this very slow CF card vs. stock 80 MB harddisk drive, the CF outperforms the HDD by far (CC with Sys. 7.5): 1'15" vs. 1'48" and 0'40" vs. 0'55" (extensions disabled).
  20. 20.0 20.1 20.2 LaCie PocketDrive, external 2.5" SCSI drive enclosure.
  21. 21.0 21.1 This copy of Drive Setup v. 7.3.5 was patched to support any attached SCSI drive, not only Apple branded drives.
  22. The CC in this setup recognises the CF device if initialised with this somewhat outdated driver. HDT 2 did not work. In case a machine does not properly detect a drive it is recommended to try a known working driver appropriate for the given Mac. In some cases it might be necessary to apply a patch to the formatter software to support recent drives.
  23. Boot time with this very slow CF card vs. internal Toshiba MK2526FB (528 MB) harddisk drive, the CF outperforms the HDD by far: 1'00" vs. 1'30" (PB180 with fully fledged Sys. 7.1) and 0'20" vs. 0'28" (extensions disabled).
  24. The PB180 in this setup recognises the CF device if initialised with this somewhat outdated driver. HDT 2 did not work. In case a machine does not properly detect a drive it is recommended to try a known working driver appropriate for the given Mac. In some cases it might be necessary to apply a patch to the formatter software to support recent drives.
  25. Boot time with this fast CF card vs. internal Toshiba MK2526FB (528 MB) harddisk drive, the CF outperforms the HDD by far: 1'00" vs. 1'30" (PB180 with fully fledged Sys. 7.1) and 0'20" vs. 0'28" (extensions disabled). The CF card reads about 1/3 faster than the fast HDD. The result is exactly the same as for the much slower Jenoptik 32 MB CF card. In combined read/write access a good HDD like the Toshiba 528 MB still performs faster, about 1/5 compared to the Kingston CF card.
  26. The PB180 in this setup recognises the CF device if initialised with this somewhat outdated driver. Drive Setup 7.3.5 did not work. In case a machine does not properly detect a drive it is recommended to try a known working driver appropriate for the given Mac. In some cases it might be necessary to apply a patch to the formatter software to support recent drives.
