I need a reliable and performant RAID controller.
Am not sure which product fits my needs best.
What I have:
- 2 SATA disks that support NCQ (Native Command queueing)
ad4: 152627MB <ST3160827AS/3.42> [310101/16/63] at ata2-master UDMA33
ad6: 152627MB <ST3160827AS/3.42> [310101/16/63] at ata3-master UDMA33
What I need:
- I want to be totally independend of special driver software
for FreeBSD, Windows XP
- Hardware RAID
The controller should present the mirrored disks as "one"
disk to BIOS / OS
- RAID levels and maintenance should be doable on BIOS level
Features I'd like:
- support for migration to bigger disks
- hot swap of disks (ability to unplug SATA cable) and maybe power,
though Im not sure if my power supply supports this
Since I currently only plan to use RAID-1 for 2 SATA disks Im
not sure, if I should pay the double price and buy the bigger
one to get more "headroom" for the future (RAID-5, or 2x RAID-1).
Are there maybe some cool reasons/features to buy the 9500-S4LP ?
Some shops refer to a different model: 9500S-4HD.
^^
Is this an older model ? Or only a typo ?
In reviews I read something about other controller:
- Intel SRCS16
- LSI Mega RAID 150-4, -6
- ICP Vortex 8546 RZ
One people noted, that one should stay away from the Intel RAID
controllers, as well as Promise and others.
Is it common experience, that the 3ware products are best
RAID controllers ? Better than the above mentioned ?
Or offer other controllers possibly some other cool features
the 3ware doesn't offer ?
