Intel made it possible for SSDs to utilize the TRIM command feature when striped in RAID 0, provided a few meaty requirements are met. The TRIM command feature works to minimize write performance degradation on SSDs, but thus far it has been impossible to enable the feature on any other host controller mode than standalone AHCI, due to the manner in which the feature works at a physical level.
According to a report, TRIM over RAID 0 will be made possible with Windows 8 operating system, provided the system is running an Intel 7-series chipset (such as Z77 Express), has RAID BIOS (Option ROM) version 11.5 or higher, and Rapid Storage Technology (RST) device driver version 11.5 or higher. While obtaining the required Windows and driver versions is relatively easy, the RAID Option ROM version is in the hands of motherboard manufacturers, who have to release motherboard BIOS updates that include the required RAID Option ROM updates.
I know it's rehashing complaints/beefs throughout the forum, but, I just don't understand why it is the motherboard manufacturers just will not officially keep the various OROMS up to date with the latest official OROMs released by the OEMs.
That said, it is especially disappointing that ASUS will not even keep there own Asmedia ROMs current with the latest update. I mean this is there child-the buck stops with them on this. The Asmedia SATA 3 chip is garbage, but, a deligent effort to improve it through ROM/software R&D/release may lessen the adverse impact.
If the OEM is providing an official BIOS update anyways why not include all the latest OROMs-everything else being equal. The one in the modded 2105b makes a nice difference on my-and many other-systems.
I personally could not care less about Windows 8; will not allow it to run on my system ever in its current release-absolutely hate it-ME/Vista all over again-which I did not buy either. I understand the need though for manufacturers to support it sooner rather than later. However, is not the same true for all the current unrepaired bugs/issues on what they have already sold. It just amazes me how fast all their PR/marketing/R&D engines go into high gear to spotlight a new component release, devote huge resources to complementing distribution/sales/adoption, while allocating the released hardware needs to the backburner-almost like "when we get a chance" kind of attitude.
I may be wrong on a lot of this, I don't know. I'm sure, though, my perception here mirrors the majority.
