  1. Another day, another new entrant into the emerging solid state drive market. Hardware maker Asus is throwing their name into the mix with a 240GB solid state drive aimed at the desktop market. I say desktop because their solution utilizes...

    I hope the price is right on this one, if it is, I'll pre-order this.

    Been looking at revodrives on ebay for a few weeks now since im limited to sata 2, This looks much much nicer however!

    This looks interesting. Yeah price will be the determining factor. I may get one if the price is right... (you reading Asus?).

    The price for the 240GB model will be ca $440
    Way too expensive IMO, much cheaper to run your own RAID0 on normal SATA3 SSD's

    How do they offer TRIM support? Win 7 and Win 8 don't do TRIM over PCIe... the hardware may support it but you'd need Linux or Unix or something else to use it.

    While thats a good question; wouldn't the price also be comparable, if the performance compared to RevoDrive?

    Been reading more into this. The drive appears as a single device on AHCI and the RAID is essentially transparent. I don't believe this gets around the issue with Windows, PCIe and TRIM as Windows won't pass TRIM across a PCIe bus.

    See this post for details:
    http://www.ocztechnologyforum.com/f...2-TRIM-support&p=755226&viewfull=1#post755226
    Note. me&er says "TRIM for your Revo x 2 is NOT currently passed through Driver filtering at the SCSI/ATA or PCIe layering."
    So the Asus drive covers the SCSI issue but it would be blocked on the PCIe layering issue. I.e. TRIM would be filtered out by the PCIe layer in Windows is my understanding.

    Are you suggesting there is not a PCIe SATA add-in card that supports TRIM for SSD drives?

    I'm investigating atm. Maybe the PCIe layer wasn't the problem. OCZ were using SCSI miniport and bridging to SATA which was losing the TRIM command. This may be why Asus's solution works and previous ones don't. Confirming with Asus now if they respond to me :)

    Apart from what the figures say, do you think you'll actually notice a difference in performance? I'm more interested in it's price & warranty than performance figures.

    Depends on what you do with your storage of course. In databases, IOPs are probably more valuable. In large sequential media file processing (stuff that isn't too CPU intensive) like perhaps 4K video, I'm sure there is a significant improvement there.

    If you are just talking game load times, you probably won't see much improvement.

    Personally, I'd go 2x 256GB SATA III (samsung 840 pros probably) drives in RAID-0. The price should come close to if not under a single 512GB and you get almost double the perf. Intel SATA 3 controllers are reasonably stable now too and we know TRIM is supported on new boards. All bases covered.

    Yeah but the Asus drive is marketed under their ROG gaming brand which can be misleading. It's doubtful it's of much benefit to the gamer, even RAID 0 SATA 3 drives are overkill. A single SSD is probably makes the most snse and the best value for money.

    This is where my hatred of ASUS escalates... Even a half-baked product on a dual Sand Force would show a way better speed via PCI Express 2.0. This one is artificially limited, so they can charge way more for a version that has no limit set in it. Damn you, ASUS! :(

    Well, it's pretty obvious this thing is targeted and pseudo-gamers. Isn't that the initial target market of the ROG brand?

    Much like those guys with tri-SLI 780's running on a 60hz 1080p screen.

    But with tri-SLI, would you have an extra card slot for this SSD card? :)

    Of course! These guys buy $400 mobos with 4+ PCIe slots, spaced appropriately!

    LOL, ahhh those guys. :)

    They probably already have the RevoDrive installed. But hey! If they have room for one more, who knows what they will buy next.

    Depends on what amount of storage you want. A single TB SSD is MUCH more expensive than 2x 512GB drives. 2x256GB drives are usually below a single 512GB drive.

    There are a few pros to RAID-0 on SSDs. In RAID-0, you are effectively adding the write lives of the 2 drives as you are halving the data written to each drive for each file. You are almost doubling IOPs, sequential reads, writes. You are also doubling the risk from freak complete drive failure which is the only real risk from what I've seen.

    You're totally correct and I agree but I was looking at this from a gaming standpoint of view seeing that this is a ROG part which are usually targeted at gamers. It seems the goalposts have shifted as far as ROG parts go.

    Yeah not much practical increase for gamers. Level load times down a fraction I guess...
