Syba SY-ENC50104 4 Bay 3.5” SATA III HDD Non-RAID Enclosure – Supports USB 3.0 & eSATA Interface, Black

It's a lovely enclosure with its aluminium case. The drive trays are well built with even a little bit of reinforcing metal on the front of them instead of being all plastic. They accommodated ssds but you do have to remove one of the retaining clips in order to make that work. However, these sleds are really easy to put 3.5-in drives into. Another nice thing about this enclosure is the LED lights are easy to read and it has a nice power switch on the front. Good news is it uses ASMedia bridge chips and hub that can pass TRIM commands and supports Linux UAS (USB attached SCSI). However, if you plug it a hub rather directly to a USB on the server processor, you will need to configure the Linux kernel. But don't dispair, Google Gemini figured out the commands and saved me from tedious web searching. Performance wise against a pair of SSDs shows the enclosure chips has low latency but can be overwhelmed easily. Fio showed good numbers for USB 3.2 SSDs as a single drive, but fell apart on dual drive read/writes. I wouldn't recommend this enclosure if you're trying to get performance for raid SSD drives. On the other hand, if these are spinning discs, it's going to be able to keep up since ssds are already operating about 200 times faster then hdds. The cooling fan kept a full stack of HDDs to 50C during a grueling ZFS scrub operation. Honestly, if you're looking for raw performance, you wouldn't buy these, you would attach your drives to an enterprise SAS solution. But since you are looking at buying an enclosure, you probably don't have that option available to you. I just say move your drives into this enclosure and you won't notice the difference between this and directly attached SAS. This DAS gets five stars for me because it's pretty much what I expect at this price point. TRIM, excellent low latency and a very attractive enclosure make this a great DAS for a home server.

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! Update 2025: Still running great 5 years later. I've since bought 2 more of these. Love em so much!

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

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.

It looks great, but doesn't work with MacBook. I downloaded the software as instructed and it just doesn't load or do anything. I found a window that than latter suggested contacting the manufacturer as the software isn't compatible.

I received the item today with different packing (not proper) Have some scratches on item as well It look like its used item

I'm very pleased with the unit. It took me about 30 minutes to install and get configured 5x old 1TB drives I had lying around. The 2.5" drives screwed right into the trays without any need for an adapter (25 screws were included as well as the mini Phillips needed for the 2.5" drives). One of the trays didn't align perfectly on insert and needed to be wiggled a bit but no big deal. It comes with a mini-DVD with configuration software that is very simple to use, and you can download it from their site if you don't have a DVD drive anymore. Mine is configured for RAID 5 with the hardware controller and working very nicely. I would definitely buy again!
