i bought this to replace 1 that was starting to drop harddrives. its not very big which i was surprised about because the 1 it is replacing is bigger even though they both hold the same amount of drives. each drive has its own power button which is great for switching out drives if you need to and the case has a power button if you want to switch everything off. the harddrives are easy to install, although the tray that the harddrive sits in is plastic so you need to take your time putting a drive into a tray. no screws required. the case itself is sturdy and made of metal and the two fans om the back so far seem to be really quiet.. each bay has its own power light and activity lightso you can see which drive is being accessed. i live in the UK and the plug is NOT UK compatible, but if you have an old kettle plug say from an old PC that works fine as that is what i had to use. all in all a nice bit of kit and i would recommend this to anyone.

This is exactly as advertised, easy to use, and works perfectly.The parts are not cheap junk plastic, they're made quite well. The fan is quiet and moves enough air to keep drives at a proper temperature.I run it without any RAID so I can't comment on that, but I've had zero issues in the few weeks I've been using it. I have it connected to a server running Debian Linux and have put it through its paces, accessing all drives, read/write tests, etc. Real-world use it performs perfectly as well.The Windows utility is easy enough to use as well as straight-forward. The box includes a USB cable as well as an eSATA cable. The directions are clear enough, and simple enough to understand.Definitely happy with this purchase and will buy another when the time comes.

Este articulo parecia una excelente solucion para tener 8 discos duros en un espacio pequeño, ventilados y por USB... Pero no lo fue.Los discos se desmontan aleatoriamente. Se tiene que reiniciar cada 2 o 3 horas para que aparezcan todos los discos.Intente instalar el ultimo firmware directamente de Syba, no funciono.Cambiar de discos y tampoco.Cambiar los lugares de los discos y tampoco.Usar otra computadora y tampoco.Usar otro sistema operativo... Y es lo mismo. Tanto en Windows, MacOs y Linux es lo mismo.Acabe perdiendo muchisimo tiempo. Ahorratelo tu tambien

Si lo que buscar es un dispositivo para usar con tus discos de gran capacidad y que no entre en estado de hibernación automáticamente sin que puedas impedirlo, algo sumamente molesto, este es tu dispositivo.Tengo conectados 4 hdd de 16tb cada uno y funcionan perfectamente, silencioso y por sobre todas las especificaciones, los discos no se apagan o entran en hibernacion cada cinco minutos sin que puedas camiar esa opcion, algo que es de agradecerse al fabricante. El costo es bastante accesible y por su facilidad de uso y sin hibernacion es perfecto para cualquier tipo de trabajo en oficina, industria u hogar.

Excelente producto... Muy fácil de instalar y configurar, con cualquier sistema operativo (Win, Mac, Lnx). Lo mejor del producto es que casi no hace ruido

I was very happy with the quality of this product. I was concerned that it might be cheap considering that it cost much less than similar products and that it was an unknown brand. It is inexpensive but definitely not cheaply made. The construction feels solid The fit and finish is excellent. I did find it slightly difficult to open the trays once the drives were installed. That might not be a bad thing, especially if you have young children around. They definitely won't be able to open the trays and remove the drives.This is not a NAS or a RAID array. It is a JBOD (just a bunch of disks) box. It is simply an external USB drive enclosure that holds 4 drives instead of one. You cannot create a RAID array with Windows using this enclosure. That's not a limitation of this particular enclosure. Windows doesn't allow you to create a RAID array over USB. It is likely possible to use this box to create a RAID array or NAS using a Raspberry Pi or another Linux based OS and open source NAS software. I didn't try it yet but I will as soon as I have 4 identical hard drives.I have a refurbished Lenovo ThinkStation that I use for a home-made DVR and media server. There was a hodgepodge of external drives attached to it that I had picked up over the years or recycled from other computers. It was quite frankly a mess. This box has cleaned up my entertainment centre and improved speeds if I have to move files around. Transfer speeds are 100mbps + when transferring between drives in the enclosure and just slightly less when transferring between the enclosure and internal drives installed in the computer. Speeds are still better on the remaining single USB enclosures as I can attach them directly to USB ports on the computer instead of a hub. I will be buying another one of these 4 bay enclosures soon to eliminate the remaining single enclosures.I purchased two new 4 TB Seagate IronWolf drives as well. Although these are NAS drives it is perfectly fine to use them as storage in a computer or in one of these enclosures. They are better quality drives than Barracudas, have longer warranties and rated for far more data transfers per year. NAS drives are meant for 24/7 operation so they are very good for home servers.I don't have eSATA on this computer so I can't comment on that but a cable is included. Installing the drives is easy and no tools are required. Instructions are not included but are available on the manufactures' website in PDF form. Although you cannot create a NAS or RAID array, you can share the drives on your network. You will then have access to the box from any device on your network as long as the computer that the box is attached to is on.Overall, I am very happy with this enclosure. I had considered investing in a NAS device but I didn't have the money to replace all of my current drives and the NAS too. I read that there are also many security vulnerabilities that allow ransomware to encrypt them. The manufacturers aren't too good at updating the software in many cases. I decided that this was the best solution for me.

Similar - and more expensive - products won't work with Android boxes, but this one will. Easy to install and works perfectly, all HDs are viewed individually by the OS. I would be nice to have individual power buttons per HD, but that's a tiny detail. Noise level could be better but it's far from noisy. That little box is awesome

Pensé que me estaba arriesgando al comprar este producto después de leer algunas reseñas.Estoy usando este enclosure con MacOS X sin ningún problema, todos los discos son detectados correctamente y estoy usando las 8 bandejas con una mezcla de discos de diferentes marcas, capacidades y tamaños.Le estoy quitando una estrella solo por el hecho de que los discos duros de 2.5" hacen que las bandejas no entren y salgan como lo hacen con los discos de 3.5", esto es por un error en el diseño que esta hecho especialmente para los discos de 3.5". Con los discos de 2.5" los clips plásticos que tienen las bandejas quedan un poco extruidos por el lado donde va el disco y esto hace que tengas que meter y sacar la bandeja a presión como forzando la entrada y salida.Fuera de eso todo ha funcionado muy bien y confirmo que los abanicos del enclosure son bastante silenciosos.

This is great value.As per other reviews here, I am astounded at the build quality and inclusions with this product. It comes with a couple of dozen little drive screws, which you would only need if you are installing 2.5 inch drives. And it comes with cables for both eSATA and USB 3.0, and they are not the usual short cables that come with drives - there is a little room to play here. I did not measure them but they are good. The POWER cord is only a couple of feet long, but it is a standard 3-prong IEC power cable! You can get one cheap anyplace you are, if you don't already have a couple of spares lying around.The RAID app is fun! I spent the day changing modes and testing speed. I've had RAID appliances before, but I'd never ever built a RAID, and it was pretty easy with the included software. I have to not that I used the software to set up my drives in it. I had an old Promise 6400 4-Bay enclosure from 2009 I think, and bay 4 was crapping out, so I took a chance on this Syba box to replace the failing Promise. I had the most recent 4x 5TB hard drives from that box, and a fifth 5TB drive I had as a spare, so in they went, and it's running fine on my Mac Mini 2012 running El Capitan. I am going in through eSATA into a Thunderbolt-to-eSATA dongle I had used with the Promise RAID. I'm currently running in RAID5. In every mode I was getting about 200MB/s up and down from this thing. It's a great box so far. If anything changes I will update this here review. Have a great day everyone!Update: a week into running this. The unit is fine, but the HW RAID Manager software for Mac now cannot see the enclosure, although the RAID volume does still mount perfectly on my desktop. I switched from eSATA to the USB connection to see if it helps, but it didn't change anything. I deleted the software management app as well as all of it's prefs and did a clean reinstall, and it still doesn't see the unit. It turned out that if I launch the application from my DOCK it won't see the drives, but if I launch the application from inside the Applications Folder the app operates correctly!! So do it that way, and all will be fine. The RAID Hardware is exceptionally well constructed, accessible, and runs very cool temperature-wise. I'm loving this thing!
