AdministrationWelcome! Please Sign In.What the SIG is…and is not.

Is – an information resource for computer users and potential computer users

Is NOT – a way to get your computer built or repaired (contact the GSBUG Daytime Hardware SIG)

Log – Random Access/Q&A (First Come…)

Administration (continued):Presentation materials will be posted at:http://gsbug.apcug.org/hwinfosig.htm

Prior presentation materials are also posted.

Hard Drives “Hard disk drive (HDD)” – a readable/ writeable,

storage device with NON-separable media; the device which stores most computer programs and data.

“IDE” – integrated drive electronics “ATA” – advanced technology attachment; ANSI for

IDE “SCSI” – small computer system interface

May 9, 2002 6


Hard Drives (continued) “Ultra ATA” – higher speed ATA, incl. Ultra ATA/33,

Ultra ATA/66, Ultra ATA/100 and Ultra ATA/133; depending on supplier, may be called UDMA (ultra direct memory access)

Primary manufacturers – IBM, Maxtor (Quantum), Seagate, Western Digital

Lesser manufacturers – Fujitsu, Hitachi, Samsung, Toshiba

May 9, 2002 7


Hard Drives (continued)Key performance indicators:

Spindle speed – faster the better Internal (media) transfer rate (Mb/sec) – higher the betterAverage seek time (ms) – lower the betterLatency (ms) – lower the betterDisk cache/buffer size (MB) – larger the better

Benchmarking:Ziff Davis’ Disk WinMark (Business and High-End) – most

recognized; virtually free

May 9, 2002 8


Hard Drives (continued)Current capacity leaders (ATA)

IBM 120GXP series & Western Digital Caviar series (up to 120GB, 7200 rpm) – ATA/100

Maxtor D540X series (up to 160GB, 5400 rpm) – ATA/100Current performance leader (ATA)

Western Digital Caviar “Special Edition” series (up to 602Mb/sec internal) – includes an 8MB cache, ATA/100, 80/100/120GB

May 9, 2002 9


Hard Drives (continued)Current leaders (SCSI) – shipping products

Capacity – Seagate Barracuda 180 (181.6GB, 7200 rpm, U160, 12 disks, 24 heads, 1.6” height)

Performance – Seagate Cheetah X15 36LP series (up to 709 Mb/sec internal, 15000 rpm, U320, max 36.7GB)

May 9, 2002 10


Hard Drives (continued)Price example - $189 for a Western Digital Caviar

“Special Edition” 80GB drive (WD800JB, direct/online); as low as $122 elsewhere on the web.

Availability – check the web, Pomona,…Reliability – even the best drives fail!Warranty – MAY be non-existent if not purchased

from a reseller that purchased through an “authorized” distributor or the drive was stolen. Check the manufacturer’s web site.

May 9, 2002 11


Hard Drives (continued)Tips:

Watch the motherboard connector keying “Short” end of cable towards the driveDrive end of cable – the “red” wire/stripe installs closest to

drive’s power connector; red wire of power connector towards the data cable.

Set BIOS to “Auto”Ultra ATA/66/100/133 drives require a 40-pin, 80-

conductor cable & compatible HDC

May 9, 2002 12


Hard Drives (continued)Tips (continued):

Put HDD on its own channelUse “cloning” software to upgrade (e.g., PowerQuest’s

Drive Copy or Drive Image, Symantec’s Ghost – as low as $9 + S&H on the web – check www.pricewatch.com).

May 9, 2002 13


“Floppies” “Floppy disk drive (FDD)” – a readable/writeable,

storage device with separable media; for our purposes uses a 3.5” “diskette” as the storage medium

Key issues:Capacity, performanceAbility to read/write standard 1.44MB FDOS compatibility Interface – available, appropriate, cost?

May 9, 2002 14


“Floppies” (continued)Standard floppy

1.44MB; 62.5KB/sec transfer (standard internal floppy)Reads/writes 1.44MB diskettes100% OS compatible (standard internal floppy) Interfaces – standard internal floppy, parallel, PCMCIA,

SCSI (internal and external), and USBLess than $10 (standard internal), Web

May 9, 2002 15


“Floppies” (continued)LS-120 (SuperDisk – Imation, Mitsubishi, Panasonic)

120MB; up to 1.1MB/sec transfer (ATAPI)Reads/writes 1.44MB diskettes<100% OS compatible (pre-DOS 5 and pre-NT3.51 not

supported) Interfaces – ATAPI, parallel, PCMCIA, SCSI (internal and

external), and USBLess than $60 (ATAPI), Web

May 9, 2002 16


“Floppies” (continued)Sony HiFD (High Capacity Floppy Disk)

200MB; claims 3.6MB/sec transfer rate, BUT only 700KB/sec “interface throughput” (USB)

Reads/writes 1.44MB diskettes<100% OS compatible (no DOS or NT support claimed,

no drivers included) Interfaces – parallel and USB (NO internal, at least

directly through Sony)…appears no longer in production/available!

May 9, 2002 17


“Floppies” (continued)ZIP (Iomega)

100 & 250MB; 1.4 & 2.4MB/sec (ATAPI, 100 & 250MB models, respectively)

Will NOT read or write 1.44MB diskettes<100% OS compatible (DOS and pre-Win 3.x not

supported) Interfaces – ATAPI, parallel, PCMCIA, SCSI (internal and

external), and USB Less than $30 (ATAPI) for 100MB, Web

GSBUG Hardware Info SIGHardware News (continued)Processors (continued)

Intel released the 2.4GHz Xeon (DP version for servers and workstations) – simple line extension.

Intel officially names McKinley (IA64) – Itanium 2 Intel released 2.26, 2.4, and 2.53GHz P4s with 533MHz FSB – first in a

series with 533MHz FSB. NOTE: While these processors will run in a 400MHz FSB motherboard, they will

run at only 75% of rated speed. As with all current Intel CPUs, these CPUs have locked FSB multipliers. A 533MHz FSB-capable motherboard is required to run at full speed. As such these CPUs may NOT be appropriate for upgrading.
