    That's a lazy question. :-) Google got it in one.

  • Sonnet Fusion Dual SATA SSD card offers Mac Pro storage expansion over PCIe

    It's $130, adds USB-C and lets users bring drives from their old machines into the MP7,1 with ease.  Hardware RAID at 1000MB/s is more than fast enough for many media tasks, larger capacities with two 4TB SSDs (8TB total), and also run a LOT cooler (aka quiet) without the need for heatsinks.  Could be a dream for audio engineers and recording setups with MP7,1.  All macOS compatible multiple blade NVMe solutions start at $400 without the blades and most commercially available blades top at 2TB max right now.
    1) It will not "run cooler" by much, nor likely at all in most tasks (ie, those that aren't hitting the SSDs 100% of the time) as the NVMe blades will finish their tasks much more quickly. Total heat generation will be lower, though more concentrated.
    2) The USB-C port may be useful to a few people, but most won't need/want it since the Mac comes with 4 (or more - up to 12).
    3) Multiblade (4, not 2 like this card) cards should be pretty cheap. AppleInsider promises to review at least one soon.
    4) If you have some old 7.68 or 15.3TB SATA drives lying around, this might, maybe, be useful - though you should also look at the Promise option too. Otherwise, a 4-way carrier with 4x NVMe modules is almost always going to be a better idea. When you're buying an nnMP you probably don't need to save a couple hundred dollars reusing old slow storage.

  • Intel confirms Thunderbolt 4 on way with four-times USB 3 speed

    JustSomeGuy1JustSomeGuy1
    Mentioned as part of its announcements for upcoming "Tiger Lake" mobile processors, Thunderbolt 4 is oddly described as having four times the throughput of "USB 3." As the base USB 3.0 has a maximum theoretical speed of 5Gb/s, this seems to be an unlikely claim to make, as Thunderbolt 2 is capable of achieving 20Gb/s, while Thunderbolt 3 is double at 40Gbps.

    It is probable Intel is referring to the more recent update of USB 3.2 Gen 2x2, which is capable of up to 20 gigabits per second when using two lanes. If so, this would put Thunderbolt 4 as reaching a throughput of up to 80 Gb/s.

    The 80 gigabits per second makes the most sense. Thunderbolt 3 uses four PCI-E 3.0 channels to achieve those speeds. In theory, Thunderbolt 4 would use four PCI-E 4.0 channels to get that higher speed.
    Unfortunately, all this is wrong, according to AnandTech, which claims to have confirmed their understanding with Intel. Intel said that they were talking about 3.2gen2, so TB4 is still at 40gbps, leaving a lot of head-scratching about what it actually offers over USB4 or TB3.

  • Review: Promise Pegasus R4i and J2i add massive storage to the new Mac Pro

    JustSomeGuy1JustSomeGuy1
    To follow up to @billalexander 's question on my wall (WTF, who knew AI even had such a thing?), the "other articles" I mentioned are other articles posted on AI, and more specifically comments made both by me and others in response. This is the OWC card: https://eshop.macsales.com/shop/ssd/owc-accelsior-4m2

    This claims not to require bifurcation so will almost certainly work.

    At $57 this is much cheaper than the OWC and probably the Amfeltec. It requires bifurcation support, and I don't know if the nnMP supports that.

    Will an SSD slot into the J2i?  Or do you need an aftermarket sled/bracket?
    This will work (with SATA SSDs) but you would be insane to do this. If you want to add SSDs, buy M.2 PCIe SSDs and put them on a carrier card, as discussed in other articles on the nnMP. If you want one with support for the Mac, get OWC's, but most should work just fine (I expect we'll see reviews here in the coming weeks). Real-world performance will be 5x better on sequential xfers and 3-5x better on random access, if you populate it with 4 SSDs.

    If you are this kind of crazy, though, you'll presumably need 2.5"->3.5" brackets, which are widely available for a couple bucks.
