Zip Drive Benchmark

Subject: ZIP Drive Benchmark Enclosed From: cam@skyview.bison.mb.ca (Cam Giesbrecht) I just purchased a ZIP drive today, so the following is a benchmark of the Zip drive compared to an internal and external hard drive, as well as the standard 1.44 MB floppy disk. ---------------------------- [Internal] Apple (Sony) 1.44 MB FDHD Floppy Disk Drive ---------------------------- Volume: untitled . . . . . . . . . . . . . . . . . Size: 1415K test size = 512K (using a temporary contiguous file of size 512K) Pass 1: Latency = 50.00 ms (600 RPM) Ave. Seek = 43.08 ms, (access = 93.08 ms) Max. Seek = 273.33 ms, (access = 323.33 ms) Write transfer rate = 61.6 KBytes/Sec. Read transfer rate = 78.6 KBytes/Sec. Simulated "Typical" rate = 56 KBytes/Sec. ---------------------------- [External] Iomega Zip SCSI Drive (w/100 MB Cartridge) * Formatted w/Zip Tools v 4.2 * ---------------------------- Volume: Zip Disk 1 (w/Zip Tools) . . . . . . . . . Size: 96507K test size = 512K (using a temporary contiguous file of size 512K) Pass 1: Latency = 10.16 ms (2952 RPM) Ave. Seek = 34.09 ms, (access = 44.25 ms) Max. Seek = 70.50 ms, (access = 80.66 ms) Write transfer rate = 1084 KBytes/Sec. Read transfer rate = 1123 KBytes/Sec. Simulated "Typical" rate = 148 KBytes/Sec. ---------------------------- [Internal] Apple Quantum SCSI (160 MB LPS) ******************************************************************* * NOTE: This volume is partitioned into 2 partitions of: * * - 120 MB startup partition * * - 40 MB data partition * * The test was performed on the larger startup partition. * ******************************************************************* * Formatted w/La CIE's SilverLining v 5.4/14 * ---------------------------- Volume: Mac OS* 7.5.1 . . . . . . . . . . . . . .

Seek = 15.59 ms, (access = 24.00 ms) Write transfer rate = 1497 KBytes/Sec. Read transfer rate = 1850 KBytes/Sec. Simulated "Typical" rate = 189 KBytes/Sec. ---------------------------- [External] APS Quantum SCSI (160 MB ELS) * Formatted w/FWB Hard Disk Toolkit Personal Edition v 1.7 * ---------------------------- Volume: Quantum HD . . . . . . . . . . . . . . . .

Seek = 23.50 ms, (access = 31.66 ms) Write transfer rate = 1367 KBytes/Sec. Read transfer rate = 1367 KBytes/Sec. Simulated "Typical" rate = 206 KBytes/Sec. ---------------------------- NOTE: These tests were performed on a Macintosh Quadra 605 with 8 MB of RAM (16 w/RAMDoubler), 32 K Cache, File Sharing Off, about 50 Extensions (basically a…
