Also unten die Werte der DPES 31080...wir haben hier ca. 10
dieser Festplatten (ab Revision S31) in Betrieb. Es gab in
dieser Gruppe Diskussionen um Probleme mit dem Gerät...
Zwei IBM laufen seit fast 4 Monaten asynchron an einer
Warpengine, eine mehrere Wochen asynch. an einem A3000, weitere
an Evoluton und meine lief 2 Tage asynch. an meinem Rechner
und sie wurde gut gefordert....aus EGO-Problemen ist sie nach
dem nächsten Reset wieder SYNCHRON...
Nichts gegen z.B. Quantum...aber viele ihrer Geräte sehen
alleine wegen fehlendem Cache völlig alt dagegen aus (Lightning).
Die IBM ist zwar nicht so flink wie die alte 500er DEC, aber
mir langt es am A3000, da der sowieso nicht schneller
kann.
Aktive Terminierung, kein gelegentliches Hängen beim Booten
(Maveric) oder Probleme beim Wechseln des Übertragungsmodus
(Syquest, Fujitsu) ,5400 UPS, 11ms, 512kB Cache, leise, "kühl"
lineare Übertragungsleistung über 80% der Platte, Rekalibrierung
nicht beobachtbar, bezüglich Bus unempfindlich..Hallo Syquest270 ;_((.
Einziges Manko: Die Anleitung...
Bisher mit der DEC die edelste Platte, die ich in dieser Größenordnung
kenne sie hat definitiv keine Probleme im asynchronen Betrieb
(allerdings habe ich nicht den Jumper auf der Platte geändert!?).
Aber Vorsicht, dies ist keine Heiligsprechung von IBM...es gibt
Platten die sind nicht toll...wohl so ähnlich wie die Maxtor/Conner,
die ich kenne:-(( 128kB Cache und dann noch schrottig...kotz.
