Does it decrees performance compare to when hard drives connected directly into RAID card?

Not that I can notice. Ive got 12 drives off it including 2 SSDs and all ok.

The short answer is I am using this in a home media server and have not noticed any performance impact.The long answer is it depends on a lot of factors. It think to answer the question for your specific case you would have to look at the characteristics of your specific controller and disks. If the controller has the throughput capabilities to drive all of your disks at peak speed then you should not see any performance impact. The controller read/write cache might need to be considered as well.Either way, I think you should be fine and the cost of being wrong is minimal when compared with adding additional raid controllers. Plus, if you get it and performance is a problem, you should be able to return it.

we have not noticed the difference, we have a pretty loud fiber raid attached as well and that would drown out the GFX card. sorry that didn't help much

I apologize for not actually answering your question. But, I just want to offer an observation. I do not believe that there will be anything to be gained by Thunderbolt 2 as long as you are connecting it to a 6Gb SATA connected drive... Or, to a spinning hard drive, for that matter. Even with a speed striped RAID won't come near the maximum capacity of a Thunderbolt 1 (or even USB 3). I think that solid state drives, attached through PCIe are going to be required to achieve any speed gains moving forward.

The RAID feature is the only difference, the choice is do you just want up to 8 individual drives (JOBD) or do you want to protect you data from loss (RAID). I have both units and they both function great.

Hello fellow Transcend card user:First of all, I am not using my card in a RAID configuration. However, I do believe your assumption is correct. I have an ASUS MoBo and to access the installed RAID functionality of the MoBo, I have to attach the hard drives directly to a specific set of SATA III I/O ports. You may want to check your MoBo manual for such requirements. You may also want to pose this question to your Mobo manufacturer. Further, you may want to consider running your RAID configuration from a USB-3 and/or e-SATA external RAID enclosure. Hope this information can be of some help - Good luck.

Absolutely. there are always SOME weird motherboards and some NAS's that don't like certain HDD's, so it isn't guaranteed, but it's a real nice, solid, good working drive. Read some reviews on it. In RAID 0, by the way, you can make up for the 5400 RPM and make these things scream and still have the low heat, low power consumption.

Yes, but since its optimized for NAS, it will be somewhat slower than a desktop optimized drive.

Yes, but the unit is advertised at 5gb/sec. You won't even see that in the real world. I am very satisfied with mine. I use it mostly for backups and it is plenty quick with my Seagate 1tb 6gb/s drive. You should use it with a USB 3.O port for best performance. Also, If you look at the device properties you should set it set for 'Quick Removal' not 'Better performance' so you can 'hot plug/unplug' it w/o worry of data corruption. I have run CrystalDiskMark benchmark tool and the best I get is approx. 90mb/sec on sequential reads/writes. You may get better results. USB will always have some amount of 'system overhead' so you will generally get much better performance w/a dedicated(on board) SATA III controller as on your motherboard. BTW, I also watch HD movies on my unit with no issues. Hope this helps.

I'm using Linux (with BTRFS which provides software raid-like features) but here are likely relevant numbers: Read performance via raid tends to be as fast as the hardware can push data. Writes may take longer as you have to write each copy per raid level. Mirrored data means writing two copies. More complicated RAID may require many reads to calculate parity and two writes for data + parity. I can get about 110 to 130 Megabytes per second read or write throughput via USB towards or from my ProBox. I don't know how Storage Spaces works internally, but you likely near full read performance (120 MBps) vs halved write performance (60 MBps).

Doesn't matter both have similar specs. I have these and WD black drives in my system, I run them both in raid 0 and both arrays perform about the same.

No, I am using it in a non-raid setup. I did try to use it with a 2 TB drive as a 4th drive. It didn't work. I then put a 500 MB drive on it and it worked. I put the 2 TB directly on a standard sata port.

Most likely not. 3GBPS was the highest speed SATA tested at the time this product review was composed. The electrical interface is identical; the connectors in this cage are not junk. Only a big bunch of mediocre cables could slow you down here.If you do not have the RAID controller yet, also consider IOfusion's PCIe bus flash, removing the SATA bottleneck.

It depends on the type of raid setup you use. There is a hybrid setup that makes use of all the drives and maximizes the space available. This way you can have different size drives. I accepted this as the default. I can't verify how it works though as all my drives are the same size. It's a bit slower than I would have liked also, but hey, it does the job.

I have this set up as a RAID-5 and hosted on a Lenovo M92p Tiny Form Factor via USB3 connection. The drive is set to be shared with homegroup users, however I have set persistent drive mappings on 4 different systems on internal 1gbps Ethernet LAN and 144mbps 802.11n wireless LAN connected computers and notice no degradation in overall performance.

Use the Intel Raid Controller that is on your motherboard if you are going RAID 0, that's what I would do. I am using the card for an SSD which was perfect for my computer, big jump in performance. Not sure how it would work under RAID 0, seeing how I have never used it for that. Hope this helps.
