re scsi or ide the bottom line in article apr msc cornell edu randy ellingson writes which would you choose and why i have both i have ide only on my dros box and ide and scsi on my unix box ide on the dros box cos it only has a hard disk scsi on my unix box cos it has a scsi hard disk cd rom and tape i bought scsi as it makes adding many devices easier for the price of one irq and dma i have three different types of device connected up faster drives are also available for scsi i have a dec dsp s that realy does have a ms average seek time i e it finds data faster than my ms toshiba drive like lots of people i d really like to increase my data transfer rate from the hard drive right now i have a ms mb ide drive seagate a and a standard ide controller card on my isa i don t think that scsi will increase your data transfer much on an isa bus i m currently thinking about adding another hd in the mb to mb range and i m thinking hard about buying a scsi drive scsi for the future benefit i believe i m getting something like kb sec transfer right now according to nu kb s is pretty good how would this number compare if i bought the state of the art scsi card for my isa pc and the state of the art scsi hard drive the best system i could hope for many state of the art scsi disks use the same mechanicals as many state of the art ide drives only the interface electronis differ look at the mb fijitsu drive for an example obviously money factors into this choice as well as any other but what would you want to use on your isa system and how much would it cost i use an adaptec b on my unix box and no name ide cards on both along those lines what kind of transfer rate could i see with my ide hd s if i were to buy the top of the line ide caching controller for my mb ms hd and how much would it cost caching controller why what does it give you that smartdrive for dos does not about kb extra lower memory that s about it a properly configured main memory cache will produce better results than a caching controller my unix reads reads data from its main memory cache at mb s that s faster than the standards isa bus can ever sustain thanks for any comments randy guy guy dawson hoskyns group plc guyd hoskyns co uk tel hoskyns uk guyd austin ibm com tel ibm austin usa
