Ссылки по теме http://web.frainresearch.org:8080/projects.../3pdiskcntl.php Сравнение контроллеров по скорости Цитата I did (and published) some benchmarks of SCSI MSCP-emulating controllers probably a decade ago. And indeed the CMD CQD 440 was the winner. But they all beat the pants off a RQDX3! Here are the peak data rates measured for read and write 64 blocks-at-a-time: Read Write ---------- ---------- Andromeda SCDC 2.298 MB/s 1.131 MB/s CMD CQD440 2.397 MB/s 1.525 MB/s CMD CQD220 1.418 MB/s 0.882 MB/s CMD CQD220A 2.088 MB/s 1.409 MB/s DEC RQZX1 1.379 MB/s 1.097 MB/s Viking QDT 0.846 MB/s 0.704 MB/s DEC RQDX3 0.164 MB/s 0.161 MB/s The benchmarks were done under RT11FB 5.7 doing 1, 2, 4, 8, 16, 32, and 64 block-at-a-time READW's and WRITW's to 16384-block data files. A KDJ11B (PDP-11/73) CPU with 2 Megabytes of Clearpoint non-PMI memory was used for the bencharmks. With the SCSI controllers a Barracuda 7200 RPM ST15230N drive was used; with the RQDX3 a RD52 drive was used. отсюда https://vmsnet.pdp-11.narkive.com/kfYv0Qt6/...-scsi-interface -------------------- Живы будем - Не помрем !
