Any advice on hard Seagate Ultra-SCSI hard disks?
Sorry for this non-Debian related post...
My office Seagate Barracuda ultra-SCSI 4.3GB is full, and I need to get
another disk. Does anyone know the Seagate Ultra-SCSI Medalist Pro?
I got these prices in Canadian currency (currently about CND$1.50 = US$1) :
ST34520N MEDALIST PRO 4.55GB SCSI ULTRA, 3.5LP 9.5MS 7200RPM $333
ST36530N MEDALIST PRO 6.5GB ULTRA SCSI, 3.5LP 11MS 7200RPM *MC=20* $588
ST39140WC MEDALIST PRO 9.10GB SCSI ULTRA, SCA 9.5MS 7200RPM *MC=20* $782
ST34572N BARRACUDA 4.55GB SCSI ULTRA, 3.5LP 8.8/9.8MS 7200RPM*MSTR CRT=10 $703
ST34572WC BARRACUDA 4.55GB SCSI ULTRA 4XL, 8.8/9.8MS 7200RPM *MSTR CRT=20* $748
ST39173N BARRACUDA 9.1GB ULTRA SCSI, 3.5HH 8MS 7200RPM *MC=10* $947
I like the Barracuda, but it's only worthwhile in 9.1GB format right now,
and you should never buy much bigger than you need for disks (prices drop
so fast).
They're both 7200 rpm disks, both with 4.17 ms Average Latency. The
tract-to-track seek is 0.8 ms on the Barracuda and 2.5 ms on the Medalist
Pro. Perhaps that makes it *feel* faster?
Any owners out there?
BTW, this is what I get on the Barracuda:
# hdparm -tT /dev/sda3
/dev/sda3:
Timing buffer-cache reads: 64 MB in 1.89 seconds =33.86 MB/sec
Timing buffered disk reads: 32 MB in 3.53 seconds = 9.07 MB/sec
