Am not sure which product fits my needs best. What I have: - 2 SATA disks that support NCQ (Native Command queueing) ad4: 152627MB [310101/16/63] at ata2-master UDMA33 ad6: 152627MB [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 ?
