Absolutely UNBELIEVABLE to me that FLASH devices are used AT ALL in hard-disk replacements!! Last I knew, FLASH devices are writeable only about 10,000 times. That is a LOW number of writes for disks if one considers DIRECTORY updates that any DOS system will do VERY often!! Even using an old "Write Back" (delayed-write) cache like SMARTDRV, or Norton NCACHE2, I doubt that writes could be minimized enough to make limited-life FLASH device "disks" worth their cost!! If the DOM products have normal RAM chips (not FLASH types) and are as "compatible" with IDE controllers as everyone seems to say, then my next "hard disk" purchase shall be another actual HARD disk or a DOM module if necessary, NOT any sort of FLASH type! Allows me to stay with UIDE, which may not use delayed-writes but takes only 944 bytes of upper/DOS memory [plus a bit of "invisible" HMA] and gives me up to 4-GB caches! Try to get even 1-GB using any "Write Back" cache, and I have 5 words for you: "Good LUCK -- You'll NEED IT"!! ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
