Based on Sil3726 chipset, the compact Rosewill RSV-S8 storage enclosure increases the amount of your storage by connecting up to eight 3.5" SATA HDDs while RAID 0, 1, 10, 5, 5+spare, spanning and JBOD support ensures performance and data security. The chassis utilizes a slide tray design to make drive swaps faster. A full 250W power supply provides ample power even under heavy load. There is also plenty of power to run the chassis exhaust fans and the drive cage fans. The well ventilated chassis helps to keep the drives cool and running on peak levels.

3 out of 5 eggsDubious software + questionable manufacturing quality

Pros: Used as JBOD for software RAID, worked as expected for some time (see below).

Cons: Some software quirks, requiring workarouds or patches as described in other reviews. Became less reliable after 1.5-2 years (see below).

Other Thoughts: As some reviews have pointed out, this unit is liable to hardware failure around the one- to two-year timeframe. A review by Chad M. suggests that the root cause of this common failure - a bank of disks blanking out and resetting at once, potentially leading to false reports of disk failure - appears to be due to shoddy workmanship on the eSATA plugs in the RSV-S8 chassis.

Having seen similar behavior myself, I tested this by nudging/twiddling the plugs on both my eSATA PCI card and on the RSV-S8 chassis itself. It was easy to verify that a single eSATA socket (the top one, in my case) on the chassis was so fragile that trivial cable movement caused the connected SATA port multiplier to reset.

Luckily, the unit is relatively easy to disassemble, and I'll be pursuing some resolution involving replacing these sockets with either new SATA->eSATA adapters or a straight SATA connection to my motherboard. But the lesson is clear: I'll be more suspicious of the manufacturing quality in Rosewill's products in the future.

2 out of 5 eggsWorks for about 1.5 yrs

Pros: When paired with a good ESATA card you can get excellent read and write speeds. I could steadily hit 800Mbps across gigabit ethernet for both read and write.

Cons: I have two of these. Both of them will not operate with all 8 trays populated after about a year and a half of use. I feel like the ESata sockets on the back of the enclosure may be the culprit. After swapping ports several times sometimes it'll work and sometimes it won't. I have both of them attached to a FreeNas PC for my personal file server. 4 2TB HDDs in each of them. I would like to have 16 but alas these enclosures won't do it anymore. I purchased a SATA to ESata expansion slot and will be gutting the internals to attempt isolate it down to the ESata sockets on the enclosure. I have tried every possible HDD configuration, swapped ports, swapped ESata cards, and swapped ESata cables. You'll know when yours is broken because 1 bank will flash off and restart constantly when under load.

Also after about 9 months of use on the first enclosure the fan died. I had to replace it which required some splicing as the fan does not use the standard fan connector (molex 4 pin, or Fan 3 pin).

Other Thoughts: Don't think I'm going to buy another Rosewill enclosure which sucks as both performed well until they started to fail and I don't want to run a bunch of 4 bay enclosures.

1 out of 5 eggsRAID Card Bad

Pros: Worked for well over 2 years

Cons: Should have worked longer than that. One day the partition table got corrupted and compromised a ton of the data. Out of the blue.

Other Thoughts: The card and software that comes with this is absolutely terrible and should never be used for any important data. It's not real hardware raid. If you want real software raid get something from LSI or something like that. Otherwise stick with software Windows or Linux raid, you'll find it much more reliable.

Manufacturer Response:

Dear Valued Customer,

4 out of 5 eggsUpdate To My Previous Review

Pros: Upon further investigation, I determined that Rosewill does indeed have a support line for this product, it's: 1-800-575-9885 Option 2. They were very helpful. After speaking with them, they informed me that the card that ships with this device does not have very good performance characteristics and that they recommend using this card instead:
Newegg item number: N82E16816115073
The drivers and software used with this card will be completely different, so please make sure to remove the old ones if you have already installed them. I will post an update after I have setup the device with the new card.

Cons: None. Update to previous review.

1 out of 5 eggsA great concept, but poor execution

Pros: Large drive capacity, low cost, compact form factor

Cons: Stability, multiple times during the installation and setup phase, the device crashed or was no longer detected upon reboot.

Performance, even when I did get it working, the performance was poor, writes were less than 7 MB/S and reads were not much better. This unit was deployed for multimedia storage, but when I attempted playback of a video from the device, it would periodically hiccup as if the data could not be read into the buffer fast enough.

Installation, I attempted to configure 8- 1TB drives in RAID5, but this device would only allow me to create 2 arrays each with 4 drives in RAID 5. Additionally, ones I created the RAID group with the 4 empty drives, the tasks it created never completed they had ETA's of over 30 hours and even when I let them run, they never finished. On the setup and instructions, after reading the 85 page PDF document, I did not see any mention of the constraints that I have run into in the RAID setup section, these should be added, additionally it would make more sense for these sections to go in order of execution, the document as it is currently formatted jumped around too much which will only confuse and frustrate novice users.

Support, I have used Rosewill for various products in the pasts such as RAID cards and KVM's, but I have never attempted to use their support. Unfortunately, they have an email contact only option on their website, I did not see any CALL SUPPORT option which is sub-optimal at best. I did email support, but I have not heard back yet.

I hope that I'm just victim of poor documentation and that there is some key setup step that I'm missing, but I have a feeling that this device may not be the solution that I need and may never meet the performance requirements I expect. I will update this review accordingly if Rosewill gives me assistance and we achieve resolution.

4 out of 5 eggsWorking well with my built-in motherboard eSATA

Pros: Was packed very well, no damage at all. Was very easy to configure once I discarded the provided eSATA card and used my motherboards built-in eSATA ports, which is a JMicron JMB36X chipset. Cooling seems to be working well, a tad loud but tolerable. Drive trays work well, thanks for the tips from other reviewers.

Cons: As another reviewer stated the provided eSATA card will not work with Gigabyte motherboard, at least not with my GA-890FXA-UD5 board. The card sees two drives then the system completely locks up so hard that I need to power cycle the system twice. I think there some compatibility issue with the SiI 3132 because I have a Rosewill RC-219 card that acts the same way.

Other Thoughts: Still not sure if the drive are spinning down during periods of no use, I Hope they are. Would be nice if it would go to sleep when the PC sleeps.

3 out of 5 eggsWorks pretty good

Pros: I was looking for a way to save some space and cable clutter and ditch several smaller 4 port external drive bay chassis. Tried this model since it was fairly priced and holds 8 drives, 1 power cable, and 2 eSATA connectors, even came with a 2 port eSATA card. I don't have any issues with drop outs or drives disappearing. Transfer rates seem in line with the varied drives I own and SATA 2 speeds. I usually leave the box on 24x7 and once all drives are recognized, they stay active. No issues with the order of LED's matching up to the right drives (saw one reviewer with that issue).
Airflow seems adequate. Just blew out all the dust and it was everywhere inside (mainly on the side vents) so it seems to be getting good airflow in and thru the box.

Cons: When turning the box I always have issues getting the top 3 drives to be recognized (LED is off). I haven't quite figured out what the issue is but it's always the top 3 and I have to start ejecting the top 4 to get it to work. The first drive on the second set of drives always works but I'm required to to eject it with the rest to get it 'kicked' into gear and recognize all 4. random ejecting and inserting of the top 4 is required and some strange pattern for all 4 to finally be picked up. the last time the box was off it was only the top 2 slots not coming active. drives don't turn on and LED stays off. once again ejecting at least the top 4 drives and reinserting in different orders was required.

Other Thoughts: box works fine once I get all the drives recognized and it only gets powered off maybe once a month or so. Usually can get the drives to work within 10 minutes but last time it took me a good 30 minutes. I'll be on the lookout for another vendor to replace this one.

2 out of 5 eggsNot so good for Linux

Pros: Nice looking.
Rosewill packs it securely.

Cons: Despite the assertions on the website, the RR622 is *not* supported by recent Linux kernels.
Bought an RC-219 controller, and it to has problems with Linux, taking 4 minutes of resetting and waiting and trying over and over again for the eSATA bus to recognize the drives. And then the first sector of my LVM array was corrupt. Fixed it somehow with debuge2fs.

Other Thoughts: Definitely will be RMAing it and replacing it with a USB3 enclosure..
The tech support phone number which Rosewill gave me regarding the RSV-S8 is for SansDigital, which is no real shock, since it looks a *lot* like the TR8M+B.
