1 out of 5 eggs

Pros: looks nice --None does not work with win 7- 64.

Cons: cables do not lock in bad quality/design. Can get array built in bios but every time i go to windows and try to format the unit crashes. Searched and found updates but that made it worse. pclink 2 kept dropping out when Windows starts. Tried to call tech support but you get voice mail and they didnt call back.
spent too many hours as it is. Bought Areca raid card for 8 drives and ripped out boards so it just holds and powers the drives.

Other Thoughts: Do'nt try to do raid with a rocket raid 622 card.

5 out of 5 eggsAmazing product

Pros: 8 Bay
Bundled Raid Card (Software)
Superb Air Flow
Long Life
Well priced

I've used this Tower for 4 years now and it has been a superb product. There are many negative reviews, but I have not had any significant issues. I use a raid 5 setup using all 8 bays. All of the drives are 2TB bargain specials which gives me 12 TB of usable space and a spare drive in case of failure. Now into year 4 the fans have been replaced as the power supply fan started to make noise and the other only made since while I was in there; the only time I was in there.
The bundled card is not amazing, but its functional. It's only pci-e 2.0 x1 and that's not enough bandwidth for this tower. Pair that with the difficulties caused by software raid I can see why people trying to use this on a less robust system might have run into serious trouble. I went with the RR642; it's still software RAID, but the x4 bandwidth helps a lot.

Cons: None
It does what supposed to do all day everyday for going on a half decade.
Not USB 3.0 Compatible

Other Thoughts: I might suggest a USB 3 device to someone getting a hard disk tower today; but I have been superbly satisfied with this purchase

1 out of 5 eggsI just carried it to the dumpster

Pros: Nice appearance. Easy drive access.

Cons: It doesn't work. I loaded it with 8 4TB WD Red drives and all it ever did was complain about them failing. They test fine in computers.
I called Rosewill and they suggest I wiggle the connectors and buy all new drives.
I just carried it to the dumpster after a year of wrestling.

Other Thoughts: Forget the whole ESata idea. Hook directly to your network via gigabit or if you don't have a network, use USB 3.0
ESata was a good idea whose time never came.

2 out of 5 eggsBeware of the included raid card!!!

Pros: The enclosure might be fine?

Cons: The included PCIe card is a significant detriment to the performance of my 4.8 GHz 6-core watercooled monstroscity of a computer. It locks up my computer for a few seconds of every minute after trying to write ANYTHING to it.

Other Thoughts: San Disk ought to ship this enclosure with one of their own cards. The included HPT RocketRaid 622 is a sad excuse for a raid controller.

I'm excited to see if a "SANS DIGITAL HA-DAT-4ESPCIE" that I just ordered will allow me to push the envelope of my 8-bay raid box...

2 out of 5 eggsnothing but fail

Pros: came with newegg gift card

Cons: bought this on july and didn't function properly since. top 4 bays would fail constantly. every time when I'm about to access (read/write) one of the drives on top 4 bays, it crashes. it power cycles and tries to boot it back up, but doesn't detect top 4 drives afterwards.

I thought ESATA cable was faulty since it does look cheap. order two extra ESATA cables but same problem. began to look at other parts for troubleshoot, naturally I assumed it was the RAID card that came with so I ordered different RAID controller but same problems. Then I suspected my HDD wasn't healthy. I have all WD from 1TB to 2TB making up total 11TB on it, so I began to run HDD check with WD diagnostic tools, all passed.
Just in case, I rotated HDD around on different 8 bays on it. no matter what type of HDD I put on top 4 bays, it crashes. so that's that. I've concluded that tower is having trouble so I RMA'ed the thing. When I received the 2nd times, it was having a same problem. always that top 4 bays.

I've tried with 3 different workstations from WHS 2003 to windows 7, and 8 environment.

Other Thoughts: Tech support and RMA department representatives are superb. very quality service and knowledgeable. too bad they have to suffer on poor devices. very disappointed on Sans Digital..

5 out of 5 eggsWorks-excellent customer service

Pros: Working well since 2012.
Customer service responded promptly and professionally to questions e-mailed in 214.

Cons: None

Other Thoughts: I had four 2 TB WD disks, arranged as two Raid 1 arrays in the lower four bays of this unit since 2012. I have had no problems. A month ago I decide to add two 4TB WD disks as yet one more Raid 1 array, and a 1.5 TB refurbished SeaGate drive as a trash file holder. The eSATA controller on my MoBO did not detect the additional disks. I asked for advice from the SansDigital Customer Support and was able to get a workaround promptly. These folks do stand behind thir product and help their customers.

4 out of 5 eggsWorks for Home Use

Pros: Has worked as a Raid5 server since 2010. I have used the Online Expansion twice and reconstruction for drive faults three times (14-24 hour rebuilds each). Removed drive cage from enclosure and installed in mid case w/ u-ATX mobo and fanless PSU for a quiet home server and backup.

Cons: Can not write more than 20 GB at a time without transfer slowing to KB/s and Windows 7 locking up unless transfer is canceled quickly. Drives can get over 110 *F when operating for extended periods unless active cooling is applied. RR622 was troublesome to setup but driver updates and fiddling got it to work after a few false builds.

Other Thoughts: 5 then 7 then 8 Samsung EcoGreen F4 2TB drives installed. Read speed of 120+ MB/s, Write speed of 60-90 MB/s. Drive spin up could take 10+ seconds but once up, instant access. Will buy again with a better RAID card or the TR8M6G . Will also get better drives with vibration sensors/resistance.

3 out of 5 eggsSans Digital Really?

Pros: Sturdy case with very easy to use hard drive trays. Trays lock in with minimal effort. Front lights are blast to watch and wish my SATA/SAS case used the same all green/flashing red when accessed scheme. 2 eSATA ports the work flawlessly with my ASUS eSATA, found all 8 drives without a hiccup. Basically a great home for my Red WD drives. But has no running water, sewer or electricity.

Cons: Tried to use the packaged Highpoint 622 card. Now I am probably alone in the Highpoint fan club as I have run a 4321 and a 4311 card in my system for the last year and a half without a problem, however the 622 is another story. I have read about problems using the card and just figured it was the systems fault or OS but that is not the case. Unless you have a MB that uses Port Multiplier eSATA ports don't buy this. The 622 can't keep up with the demands of an 4 drive array and forget 8 drives. Timeout, stop, stall, waiting system not responding.

Other Thoughts: Ok bashing over Sans Digital made a great case for what I needed the 622 was an experiment and I never really intended on using the card, but for those who need the card buy something else like the Sans Digital eSATA,1394B, usb 3.0 Raid 4 drive cages. This product is just a good home for the drives you have to come up with the connection to your system.

1 out of 5 eggsMonths later... It was not the hard drives

Pros: Cheap and has lots of drives, and its SATA3!

Cons: Constantly crashes over and over and over and over again. Basically when you read or write data to either a single drive or a Raid array and you look at it the wrong way it ends up basically power cycling the bay (top or bottom 4 drives) that triggered the issue. It will continue to do this (btw you computer locks up on you doe 1 second repeating every 3 to 5 seconds over and over till the write cache is emptied). Also this all causes your system to BSOD if it really does not like what your doing.

I am using 3TB WD RED drives, I started with 4, but with all these problems i thought i had drives with bad sectors (btw never use a usb to SATA cable to run diag tools on a drive). but after 2 drive replacements and still having the issue (the drives were never the problem i just got bad readings) i ended up buying 2 more drives and removing 1 of the 4 RAID 5 drives in order to pull off all the data onto each drive individually.

BTW every time i rebuild the array that was 27 hours when dealing with a 4 drive 9TB(12tb) RAID 5. Also when it checks the drives consistency and it did its little crash it freaked out and thought one of the drives was bad (and it probably was not) and then you had 27 hours where you basically can't touch the drives while they rebuild or they will crash

Currently have i have 6 drives in this all running in the Legacy setup, with no RAID, this way i have 3 drives on the top and 3 on the bottom, so when it crashes i am not interrupting stuff running on the other drives... sigh

So one option is to get a different eSATA card, but honestly looking at any of the ones offering 2 external eSATA ports, i don't see any that look all that good, also there is nothing to say that the board's in the tower are not the issue.

I have played with caching on both the management tool and in the OS, also used tools like TeraCopy to better manage copying to the drives (needed to do this because of all the issues with copying files to the drives)

Other Thoughts: I think your best option is to suck it up and buy a real card, spend the 200 to 300 to get a real SATA/SAS card with those fancy breakout cables, and use that in a tower that has some extra drive bays.

1 out of 5 eggsGood only for minimal I/O

Pros: Cheap, nice design, easy access to drives

Cons: began failing with a blur screen after 2-3 months.

At first the drive worked great, however, as the I/O traffic began increasing the unit started failing. First, it would freeze while accessing the drive and you could see the light blink, then it would turn off access to all of the drives, cycle through them and restart the I/O. This would also freeze Windows for the cycling period (Windows 7 prof)

About 3 months after the purchase, then unit would just crash with blue screen. Once the computer gets to BIOS, it would not even see any of the drives. Occasionally, it would find one or two out of 8. Sometimes I had the whole system unplugged from the power and it would start working again, but then eventually fail. First I thought than it might be the PCI card, but then I opened the unit and discovered that the drives and unit chips are very hot!

Not sure what I will do about it. I have about 12 TB on it and can only access 4 or 6 TB at best.

Other Thoughts: I will see if the fan could be switched for a better one or maybe just shoving another one in the back. In any case: if u plan on using the storage for heavy traffic (such as a media storage) stay away.
