Hi Marcelo,

Thank you for contacting Pogoplug Support. We are using a Marvell 88F6192 chip with ARM V5 CPU 800Mhz and 128 ram.

Regards,

Pogoplug Support


Marcelo Henrique Manzo, Dec-14 22:10 (IST):
I would like to know how much CPU (Ghz) and Ram the Pogoplug Series 4 has.

Thank you,

Marcelo

[Edited to comply with the coplaint in the next comment]...

Fabulous, Marcelo! Thank you for this very quick investigational query!
My comments...

As far as hardware I/O and form factor, the new PogoPlug series 4 looks like a winner! I would like to see a thorough review that determines if an 800 MHz processor can keep up with 2 USB 3 ports, a SATA port, another USB 2 port, SD access and a fast FIOS connection to the world (with perhaps 2 or 3 users trying to suck down movies at the same time!) Two years ago, Marvell announced a souped up Plug Computer 3.0 reference design with a 2GHz processor. But the products never followed. (Perhaps PogoPlug got tired of waiting for reference kit?).

Some users may ask for WiFi. It's included on some GuruPlug models and the never-materialized PC3 reference design. But what could possibly prevent users from attaching a Plug Computer directly to their router? I really don't see a point to Wifi in a device that stays connected and acts as a server to owners on the go.

Likewise (at least, for me) the cloud service is a Red Herring. The whole point of a Plug Computer is to serve the cloud from your own home or office) Pogo is trying to be a cloud provider (like Apple, Amazon, DropBox and everyone else). But let's face it. They sell a product that frees you from 3rd parties and data centers. Perhaps they should market their cloud service as a backup to the personal cloud. Of course, with their current price structure, it could get very expensive. I have 2 and 3 TB drives attached to my Pogoplug.

Even better, I would like to see the cloud allocate remote space to users on all the attached drives of all the peers -- in a distributed, encrypted, global P2P torrent. A distributed data cloud with no data centers. Symform and SpaceMonkey are setting up this model now to compete with SugarSync & DropBox. They both use an RDDC model (Reverse Distributed Data Cloud)

For me, the only real problem with the PogoPlug model is that it is dependant upon a web "go-between" and centralized aps rather than an single-step IP resolver. I prefer the Tonido model which doesn't require a subscription and greatly enhances privacy.

Some better research could have saved you some time on hypothesizing, baseless accusations, and false claims. Pogoplug switched over to the (now firesaled) oxnas platform from PLX only a few months before Marvell released their Armada line of processors, which handily beats the pants off of what Pogoplug tried to do in their Pro/Video incarnations/disasters. There are multiple platforms that use Armada chipsets, with development boards from Marvell (obviously) and CompuLab, and full devices from Globalscale and Buffalo, along with many other third party corporations in various implementations. And given that the latest and greatest versions of the processor are dual-core and use ARMv7 instruction sets with a hardware FPU, the only thing to see looking back at Pogoplug is the dust cloud they were left in.

Wifi on-board is more of a personal need/want and is too subjective of a topic to assess as a flaw in a device that does or does not have the capability. To most it's about convenience, less wiring, or just that they ran out of ports on their router.

On the topic of throughput and your GoFlex Net scenario, the entire armv5 repo is maintained using two of those sitting on my desk. Given that I see on average 50MB/s flowing back and forth through those devices just off of distcc and iSCSI access, you're doing something wrong if you're getting whatever your 1-3% of something actually computes to. To compare what I do locally, you would need 16 of your FIOS lines bonded to handle the traffic I generate from one of the devices. And this is just random data access and transfer for compiling, streaming they perform even better. They are incredibly competent at data transfer when you treat them right and set them up properly. A computer system is only as good as the person operating it.

Lastly, these forums are forums, not blog spots. We don't care what the Pogoplug software does, doesn't do, sucks at, or excels at, because this distribution is a replacement for it. Debating the finer points of what their global domination tactics are would be a better fit for forums geared toward that subject, or for your personal wordpress installation. Your advertising has also been removed for you.

Re: Pogoplug Series 4 - Hardware CPU / Memory RAM

For those that might be wondering if the PP4 is an overall improvement, the answer is no. There is one caveat only, and that is that there is USB 3.0 functionality enabled via the PCIe bus. You can take that however you want, especially since a SATA port is next door.

Here are the formal differences in the chipsets, which differ only in their processor and memory capabilities. The 88F6192 listed first is what is in the PP4, with the 88F6281 being in plugs such as the Pogoplug v2, Dockstar, GoFlex Home/Net, and others.

Code: Select all
                   88F6192                      88F6281
CPU Core           Running at 800 MHz, L2       Running at 1.0, 1.2, or 1.5 GHz
                   cache at up to 400 MHz       and L2 cache at up to 500 MHz

TCLK Frequency     166 MHz                      200 MHz

DDR SDRAM          200 MHz clock, 400 MHz data  400 MHz clock, 800 MHz data rate
                   Two DRAM chip selects        Four DRAM chip selects
                   DDR2 densities up to 1Gb     DDR2 densities up to 2Gb
                   Up to 16 open pages          Up to 32 open pages
                   512MB total address space    2GB total address space

GPIO Port          36-bits                      50-bits


Aside from those differences, everything else remains the same including SATA, GbE, PCIe, MPEG TS, Audio, CESA, USB, etc. The PP4 is essentially a step down from their original models, and of course from the oxnas variant. The good side of it all though is that they released a product once again that has mainline kernel support, and we should shortly have some information on getting ALARM installed now that the devices are in the hands of our team.

Mine's coming on Monday. Seems like each revision of the hardware gets progressively worse. At lease we didn't spend $99 on it. Has anyone done a quick speed test of the USB 3.0?

Thanks, USB 3.0 speeds look pretty good. Not really sure about the 7zip speeds definitely looks slower than the other pogoplugs.

Unless I'm horribly mistaken, my post above definitively shows the pp4 to be slower in both clock speed and memory. Basic math applies: 800 MHz < 1.2 GHz (or 1200 MHz).
