Vielen Dank für die ausführliche Aufklärung bzgl. SCA. :))))
Ok, ich bin im Moment dabei nach Seagateplatten zu suchen. Nochmal zum Durchsatz.
Was muss eine gute SCSI 160 Platte bringen?
Ich schaue jetzt z.B. auf diese Seagate ST336704LW (Cheetah 36LP) und habe bei Seagate folgendes gefunden:

SPINDLE SPEED (RPM) _______________10,033
AVERAGE LATENCY (mSEC) ____________2.99
BUFFER (/optional LWV and LCV) ____4MB/16MB
Read Look-Ahead, Adaptive,
Multi-Segmented Cache

BPI (PEAK KBITS PER INCH) _________334
AVERAGE ACCESS (ms read/write)_____5.4/6.2
Drive level without controller overhead
SINGLE TRACK SEEK (ms read/write) _0.8/1.1
MAX FULL SEEK (ms read/write) _____11.2/11.9
MTBF (power-on hours) _____________1,200,000
SHOCK (G's, 11/2/.5 ms):
operating (Read/Write) ___10
abnormal _________________40
nonoperating _____________75/200/100
ACOUSTICS (Bels typical, sound power) ____3.9
POWER DISSIPATION (watts/BTUs) Active ____/
Idle ______10.91/37.2
POWER REQUIREMENTS: +12V START-UP (amps) _2.2
+12V TYPICAL (amps) __0.58 idle
+5V START-UP (amps) __0.86
+5V TYPICAL (amps) ___0.79 idle
IDLE (watts) _________
LANDING ZONE (cyl) _______________________AUTO PARK
IBM AT DRIVE TYPE ________________________0 or NONE
Physical:
Height (inches/mm): 1.0/25.4
Width (inches/mm): 4.00/101.6

Weight (lbs/kg): 1.3/0.589
Da steht jetzt was von Internal und External Transferrate. Sind das jetzt gute Werte?
Und noch was, was wäre ein realistischer Preis für diese Platte? (gebraucht)
