Pocketable Thunderbolt drive promises 750MB/s transfer rates

Most of the Thunderbolt-equipped storage devices on the market employ arrays of mechanical hard drives. Not Promise’s Pegasus J2, which is being billed as the fastest one of them all. This external drive combines a pair of SSDs to enable transfer rates as high as 750MB/s. Rather than using 2.5″ solid-state drives, the J2 is loaded with a pair of smaller mSATA drives, allowing the whole thing to be stuffed into a tiny case measuring 2.9″ x 4.3″ x 0.8″. Total weight: just 140 grams.

Promise doesn’t provide any details on the controllers or NAND used in the component SSDs. However, it does indicate that the dual drives are configured in a software RAID 0 array by default. Users can opt for RAID 1 and JBOD arrays instead, but those won’t deliver the full 750MB/s. Indeed, neither will powering the J2 with a standard Thunderbolt cable. To reach top speed, the Pegasus J2 needs to draw auxiliary power from a wall socket. The J2 is capable of running on Thunderbolt power alone, but Promise doesn’t say how much performance is sacrificed by ditching the adapter.

Although the power adapter is included with the Pegasus J2, a Thunderbolt cable is not. You’ll need to provide your own, which adds about $50 to the J2’s already steep asking price. The 256GB model sells for $800, while the 512GB model costs an arresting $1500. For reference, a couple of 256GB mSATA drives will set you back less than $600 at Newegg. Most of the mSATA drives Newegg has in stock come with three-year warranties, but the J2 is covered for just two years. That seems a little stingy for such a premium device.

Right now, the Pegasus J2 supports Mac OS X only. I expect Intel will encourage Promise to add Windows support, but there aren’t that many PCs out there with Thunderbolt ports right now.

    Woo, 750MB/s to all those Macbooks with slow first-gen Samsung SSD’s?
    As far as I know even current Macbook SSD’s aren’t even close to being that fast….

    2.9″ x 4.3″ x 0.8″?

    Woudn’t a pair of regular 2.5″ SSDs only be *slightly* thicker than that?

    • Bensam123
    • 7 years ago

    lol, so this drive manufacturer went around the whole 2.5″ cartel and simply made an array out of msata drives. XD

    And people said there is no place in the world for 3.5″ SSDs. I’m sure other people also see that 2.5 SSDs are becoming homogenized.

    OS X. Mac OS X died a quiet death a while ago.

    SATA 3 spec calls home and asks for sata 4 spec asap so it won’t get beat by Tbolt.

    16x PCIe slot looks at both and laughs at their bandwidth.

    edit – [url<]http://en.wikipedia.org/wiki/File:Thunderbolt_Technology_model_1_E.png[/url<] ahhh no wonder sata can't keep up. So the next question is, will next gen ssd's and mobo's get tbolt (mini diplay ports) with pcie ver 3.0 speeds? Then again someone may try to plug their ssd into their vid card.

    Only a Mac user would own a product this expensive and outlandish.

        So tempted to buy this and connect it to my ASUS motherboard. To hell with the OS X requirements!

      OUT OF STOCK.

      Therefore Newegg pricing invalid. It may not be so in this case, but Newegg often alters the prices of OOS items to reflect the likelihood of restock.

        • Shambles
        • 7 years ago

        Yes, because a NE is a tiny little store that doesn’t have the ability to restock basic items like the Crucial M4. Give me a break, this drive’s consistently been in stock week in and week out. Wait 2 days for it.

          • UberGerbil
          • 7 years ago

          They’ve been running a lot of sales on it recently, which suggests they (Crucial and/or NewEgg) may be clearing inventory in anticipation of a new model with the next-gen NAND.

    On a related topic: what’s the fastest USB 3 thumb drive available?

      • ChronoReverse
      • 7 years ago

      Probably the Patriot Supersonic Magnum: 200MB/s and sequential write speed up to 120MB/s

        • flip-mode
        • 7 years ago

        Wow, I am quite surprised at prices of USB 3 flash. I don’t know what I was expecting as I have never looked at prices before, but I guess I was expecting higher prices that I’m seeing.

          • DancinJack
          • 7 years ago

          There are faster ones, at least according to newegg specs.

          • DPete27
          • 7 years ago

          Why so suprised? SSDs are at or below $1/GB. If anything, I feel like flash drives are a bit pricey for what you’re getting. Portability costs money I guess.

      • Shambles
      • 7 years ago

      I wouldn’t mind knowing some suggestions as well. I’m not looking for premium models but for mainstream stuff so far the 32GB Sandisk Extreme is looking like one of the better ones. Anything else of comparable value out there now?

        • DPete27
        • 7 years ago

        I love my [url=http://www.newegg.com/Product/Product.aspx?Item=N82E16820313215<]Team X101[/url<] I actually get slightly higher than advertised transfer speeds on a clean drive.

      • Bensam123
      • 7 years ago

      You have to read through the comments on Newegg… But this seems to be a decent place when I was looking around.

      [url<]http://usbflashspeed.com/[/url<] The reliability of such a database is up in the air though. :p

    Why does this need a wall socket? 2.5″ external hard drives can be powered with USB2.0 at 2.5W while thunderbolt offers 10W. How much power do these two mSATA SSDs really need?

      • brucethemoose
      • 7 years ago

      ^^

      My particular adapter comes with 2xUSB 2.0 for 5W. So this draws more power than 2 2.5″ mechanical drives?

      • NeelyCam
      • 7 years ago

      If you look at reviews of recent high-speed SSDs, the active power consumption can reach 4-5W. Include the Thunderbolt controller and the active transceiver in the cable, it all adds up quickly.

      • Forge
      • 7 years ago

      Well, you need about 2W at peak for the mSATA drives, and another 15W for the Promise controller, and 45W for the old Atom CPU to run the OS and drivers.

      (Promise makes fakeraid controllers. I’m sure there’s an ARM CPU or FPGA in there doing the hard work.)

        • DPete27
        • 7 years ago

        Haha, but seriously. Even the [url=http://www.ocztechnology.com/ocz-revodrive-3-x2-pci-express-ssd.html<]RevoDrive 3 x2[/url<] uses less than 10W under load.

    Cool product, but damn, tb cables are still 50$???

      • Farting Bob
      • 7 years ago

      How else are they going to make $45 profit for everyone they sell??

      • NeelyCam
      • 7 years ago

      TB is for high-end. The 99% would be fine with USB3.0.

      The only good thing about TB was that it carries more power, but as is shown over here, it’s just not enough. If you’re gonna have to use an AC adapter for your fancy new “pocketable” drive, why not use USB3.0 and save a [i<]whole lot[/i<] of money?

        • destroy.all.monsters
        • 7 years ago

        What’s also nice about it is that you can use Firewire (and I believe USB too) through adapters. Firewire peripherals got a new lease on life as a result.

      • destroy.all.monsters
      • 7 years ago

      Remember that active SCSI cables used to cost 50 smackers in 1990s money (Granite Digital for the win). These are cheaper.

      Although I risk sounding like my parents “we used to see movies for a dime”.

      Which is not to say that it’s cheap but it’s also cheaper than a lot of those Monster branded cables (or in the same ballpark).
