Take this as a learning experience Ganesh. There is no reason why a reviewer ( hopefully someone with some expertise ) should not as Ganesh Is that if someone can have knowledge of something without laying hands on actual hardware. As eSATA PM technology has always been of interest to me. Just a lot of reading over the past several years ( since the specification was released ). I on the other hand have no hands on experience. Is that you have actual hands on experience with the hardware / technology. The difference between you and I however. Granted, a few Addonics products can / do this for the user through hardware switches. If I understood what was written correctly. It is miraculous that the reviewer was even able to see even a single drive. However, that array has to have previously been setup with an appropriate SI controller( or equivalent ). Sometimes, with the right equipment, you *can* perhaps access RAID arrays previously setup by a system that did have the right controller chip set. Is that port multiplier technology does not work without the proper controller chip set period. Complaining, whining, or otherwise crying about hardware not included is simply inexcusable. You *do not* go out and test equipment like this without having the proper support hardware as well. obvious inexperience with the given technology. However, I like you recognized the authors um. yyrkoon - Sunday, Auglink Yeah I got that.This is why yours truly completely opted out of eSATA entirely, and went with USB3. Where drives suddenly drop offline, experience terrible speeds. I think you would find that with many, many eSATA implementations. If someone were to make say a 4 SATA drive to Thunderbolt bridge device.Īs for the "bad customer service thread thing". Thunderbolt I think could be a great option too. USB3 is not great, but it is good enough and flexible. I think that manufactures should just leave eSATA out of the mix, and pass the savings onto us. Where you have to ask yourself "why eSATA instead of SAS, or ( insert other external drive technology here ). From specification to end user product however. However, do not get me wrong, I personally was very interested in eSATA PM technology from the start 5+ years ago. It is complicated, convoluted, and in general half baked from conception compared to other technologies. This is the problem with multiple drive eSATA technology. You had better know what you're getting into, and you should already know this. No use in lamenting over a controller card not being included. But it looked like you were saying that Mediasonic's eSATA implementation was bad. My point was that technically, the eSATA issues you had, was all the fault of the hardware you used to connect to the tower. yyrkoon - Saturday, Auglink "I think all our readers know enough to understand that USB 3.0 has no port multiplication feature :)".It should be able to satisfy the needs of most consumers looking for a 8-bay JBOD enclosure. Thanks to its dual interface, the Mediasonic Probox enclosure is compliant with a wide range of systems. However, the rise in popularity of USB 3.0 probably means that vendors don't want to spend too much effort on this. Motherboard vendors should also make sure that their eSATA ports conform to the port multiplier specifications. Bridge chips capable of 6 Gbps support would definitely become necessary when DAS units with SSD support come to the market. With eight drives being accessed simultaneously, it is quite easy to saturate a 3 Gbps link.
#Mediasonic hw180stb not find any usb device full
The bridge chips conform to the SATA 3 Gbps specification only, and USB 3.0 port is unable to deliver full performance. The only way to solve this issue would be for Mediasonic to bundle a tray capable ot supporting both 2.5" and 3.5" HDDs and slotting in perfectly with the fixed SATA connectors inside the unit. The unit forsakes support for 2.5" HDDs / SSDs, and the latter don't work even with 3.5" adapters. Even in that case, only add-on cards using the Silicon Image 3132 / 3124 controller can access all the eight drives using the port multiplier feature (standard specifications seem to call for support of upto 5 SATA devices only through a port multiplied link)įor the pricing of the device (more than $250), an add-on card with the appropriate Silicon Image controller must be bundled Provides quick access to upto eight 3.5" SATA HDDsįulfills basic functionality without flaws and has decent performanceĭual interface (eSATA and USB 3.0) supportĪutomatic fan control and ability to turn on and off along with the PCĮSATA is unusable for configurations with more than one drive unless SATA controllers with port multiplier support are used. As we come to the business end of the review, we will summarize the pros and cons of the Mediasonic Probox 8-bay JBOD unit first.
