As promised in the review of Lexar DD512, I tried for a few months the remaining components of the Lexar Professional Workflow. To recap, for those who missed the first review, the system consists of a Docking Station, USB 3.0 version available (HR1) or Thunderbolt 2 (HR2), and various Add-ons that plug into it. Players are available for the most common memory cards (microSD, SD, CF, D) 256 or 512 GB SSD and two respectively. We analyze the various aspects of this system. Aesthetically, each component has the same finish: glossy plastic on the front and back, and plastic for the body. The connections are always on the back while the bottom has a non-slip rubber ring.
The Docking Station follows the rounded lines of the other system components, is wide and deep high 150 mm, 110 mm 85 mm (without the accessories inside), while deep space increases to 105 mm with the discs (or readers) inserted, because out of 2 cm. On the front are 4 slot nicely finished within which there is a USB 3.0 type B, while on the back there is the entrance to the USB plug and socket, necessary to connect more than one unit to HR1. The power supply is included in the Electronicsmatter, as well as the USB 3.0.
SSDS, already reviewed, have 5 LEDs on the front showing disk space with steps of 20%, while blue indicates the ignition and the task at hand. Compared to the previous review I can add that the LEDs that indicate the capacity involved only work with ExFat formatted disk, whereas with all other File systems will turn on the first, third and fifth.
Readers have the slot for inserting the card on the front and a blue LED (much brighter than that of the discs) that reports the memory input and activity on it. I really appreciated the inclusion of a “stopper” soft rubber to be applied to readers when they are not used. I bought the SD reader and one for the CF, but there are also the model for the D and that for microSD.
The Doking Station HR1 (USB 3.0) is the component that has piqued my interest, because I immediately imagined the potential use in RAID disks and, most importantly, costs very little. Unfortunately I have to immediately dampen enthusiasm of all those who, like me, they hoped. In fact the RAID 0 is feasible on Mac OS X using Disk Utility and handles well, but alas the read and write speeds that result are even lower than the single disc. I also did more tests and I think it’s a limitation of the controller Dock HR1, in fact if you connect a USB 3.0 drives powered the speed increase, but if you want to really achieve the desired result the disks must be connected separately on different ports on the same computer. With this last configuration I reached 752MB/s 457MB/s write and read, while the single drive stops, respectively to 423MB/s and 236MB/s. A real shame you can’t achieve the same results with SSDS connected in your Dock.
