Dual Bay Raid Enclosure for 3.5” SATA HDD, 10Gbps SATA Docking Station with Adajustable Fan, 4 Raid Modes,Type C SATA Enclosure for 44TB Capacity Expansion

Tenia mis dudas, llego dos días antes de lo mencionado, muy facil de armar, la calidad de producto es muy buena, le instale cuantro discos de 1tb y por medio de de los swiches y siguiendo el manual logrpe tener un raid de 4Tb y ademas muy rápido, el raid lo formaté en exFat y funciona excelente en PA y MAC, sin duda hice una excelente compra y si estoy coiderando en un futuro ardquiri otros.

The fiddly screwing in of all the parts for installing the drives could be problematic for some. More screws than I would like are used but the resulting device is quite solid and seems very sturdy. I am not in the habit of dropping devices but do feel this would take a drop and continue to function well. The drives are not going to fall out and the balance of the device seems to be well thought out. As I am using it through a USB 3 hub, it was a true plug and play experience, with no downside. My drives were all preconfigured under NTSF and just showed up in Windows. No reboot, no formatting. All extant files accessible normally. The internal controller turns out to be a J MIcron unit that is quite stable and widely used in many USB drive docks and some enclosures. Solid performance well within the expected range. The internal fans, having their own switrch can get a bit noisy under full speed but the mid point, while noticeable, is a reasonable level. The drives themselves remain well under 40C, which is what I find acceptable. The price is fair, the quality is there. The performance and stability are quite acceptable. I am ordering a second one. EDIT: The second one was the same in every way. Amusing it to back up my laptop in an offline manner, so not constantly on. Just freaking works under W10 and 11. Am very happy with both. EDIT: Glutton for punishment here. Now have 3 units and all work the same fine trouble free way. EDIT: 4th one now. As these will handle up to 18TB drives, you can really get a lot of storage for all the cat videos and pictures, jokes your older relatives send you and OFC the back ups of your operating system you always make. As this device supports RAID at different levels there is also a measure of redundancy in that in several of those modes, one disk can fail and you will be able to recover the data relatively painlessly. Am using two in RAID 5 and the performance is quite good, max USB 3 speed in and out.

It works. It has cooling, sufficient for ordinary HDDs, I recommend those with lower RPM. "Works" is an important feature, because many similar devices do not work. While the electronics is somewhat old already, a RAID1 with quite inexpensive HDDs will save you from warring about infrequent, but very unpleasant storage crashes.

I got this for 4x drive RAID-5 and thought the price was amazing for a hardware raid controller and it still is. If you want a hardware RAID-5 and are perfectly fine with being limited to around 200MB/s transfer speed then you'll have no issue with this enclosure. Extra plus if you plan to take advantage of the HDMI interface on the enclosure. I guess some folks use a JBOD as a dock. This being a fancy JBOD with built-in hardware RAID, but with an unfortunate choice of an ancient controller chip. The problem is they built a new product using JMicron JMB393 controller, this chip was released in 2008 and the entire bus speed for all 4x drives will be limited to 3GB/s transfer speed. To be clear, this unit still supports SATA-III (3) drives because all SATA drives are backwards compatible with older SATA revisions. I was fooled by the USB-C interface, I believe the inventors of this device went with a Type-C interface for anyone who wants to connect their monitor through the enclosure... What I can't understand is why build a new product in 2022/2023 (design was likely done last year) and use a chip from 2008. When I first realized I was only getting 200MB/s (and before I saw/realized the specs/limitations on the JMicron controller) I set the jumpers into "Normal" mode and did a transfer test to each drive simultaneously thinking that the RAID-5 calculation was the speed issue... Then I started getting 50MB/s to each drive... I launched the trusty "USB Device Tree Viewer" to confirm I was getting the right speed values and sure enough I was getting "Device Connection Speed : SuperSpeed" which was the maximum speed available for the device. The manufacturer certainly wasn't cheap with cabling, the USB cables provided are of high quality and give a SuperSpeed connection effortlessly. I would also like to state that I purchased several "compatily LX23 40TB (Dual 20TB)" from the same vendor and am happy with that purchase. I'll be reviewing the LX23 40TB separately and will be giving 5 stars.

I have put in a couple of 1TB disc drives. One has a transfer rate all about 200 megabytes the other above 170. This is pretty good and I would like to continue using it plugged into a mini PC with USB 3.2 sockets. My main problem seems to be that if. it is not in concert use the computer which is is connected to lose a connection and I have to physically switch the device off and on to get connection again. This may well make it usable as a occasional backup resource. Anybody with similar problems please post
