Lines: 25 Well I was going to wait for the SDPI from ASDG but since this will not be around until mid 88 I have decided to plunge into a hard disk now. I went to the local computer outlet and tried the CA 2090 with a Miniscribe and was not all that pleased with the performance. I began looking through the computer shopper for faster hard disks but knew that the real problem was the File system and OS. Well I saw an Ad in another magazine for a hard disk from Supra Corp and gave them a call and was pleasently surprised. It seems that in early january they will be shipping a 30M drive with controller which Abels will sell for $675.00. It has a 65 msec access time (pretty slow) but the controller is what got to me! It formats the disk with a 1:1 sector interleave (versus about 3:1 with current software and 2090) which means the files are stored as phyically contiguous sectors for increased speed, It buffers full tracks (a great trick since it is often just as fast to read a track as it is a single sector) and stores data in RLL format (for about 3Xs the data per sector almost tripling the effective Xfer rate). The tech I talked too said they intend to support auto boot as well! Now I am in no way connected with Supra Corp. and have never even heard of them before, does anyone know of this Company? I have placed an advance order with Abels and will keep you all posted if I ever get a chance to use this hardware in the next few weeks. Anyone hear of anything better which will be available in the near future? -Roger
