Hello,
I'm building a brand new computer and I'd like to highly customize it so it's important to take the right decission before buying components, etc. I'd need help with the storage choosing.
I'm evaluating two possible solutions:
A) Only one fast hard-disk. The model would be:
HD SATA150 150GB WESTERN DIGITAL RAPTOR WD1500ADFD 10KRPM
B) RAID (possibly a mirror), with two hard-disks. The model would be:
SAMSUNG HD501LJ (SATA/300, 7200 rpm)
The cost seems similar (Raptor is extreeeeemely expensive!!) so I'd choose basing mainly on performance (security would be a bonus). Which one would you take? Why? I plan to run a Windows OS installed on any of the above hardware solutions.
Actually, the mainboard I've choosen is very powerful (it supports RAID & SATA/300). I've choose this one:
P5B PREM VISTA S775 P965 ATX SND+2GLN+U2 +1394 FSB1066 SATA2. Mainboard storage features:
Southbridge
- 6 x SATA 3.0 Gb/s
- Tecnología Intel Matrix Storage soporte RAID 0, 1, 5 y 10
Controlador JMicron® JMB363 PATA y SATA
- 1 x UltraDMA 133/100/66 para hasta 2 dispositivos PATA
- 1 x SATA interno 3.0 Gb/s
- 1 x SATA externo 3.0 Gb/s (SATA On-the-Go)
- Soporte SATA RAID 0, 1 y JBOD (por 1x SATA externo y 1x SATA interno)
My little&own comparative:
Pros for Raptor (Solution A):
- write operations would be faster than RAID (10Krpm vs 7200rpm)
- less power comsumption (one HD vs two HDs)
Pros for "cheap RAID" (Solution B):
- it is SATA/300 based (Raptor is SATA/150)
- redundancy (mirror)
- more capacity (500 GB vs 150 GB)
- read operations faster :-? (2x7200 rpm vs 10Krpm)
* What about read operations? Which one would be faster: RAID/7200 rpm or single/10Krpm?
* In practice, would I note a notable performance increase if using SATA/300 over SATA/150? (I suppose I do if I'm transfering big files, am I right?).
* Really I don't see how a big price like the Raptor one could be justificated... Maybe I'm wrong and a 10krpm disk will beat a two-7200 raid in terms of performance...
Please, let me know which your opinion is. I'd greatly appreciate your comments!
Thank you in advance.
