Pros: It is tiny and it works. Adds four SATA ports. It shows up as an AHCI device so no special drivers are needed for Linux or Windows 7/8. Included four SATA3 cables, one for each port. Also includes full and half-height brackets in case you are installing it in a small system. Already has the latest BIOS installed, nothing needed to be updated.
Cons: No cons so far. It does exactly what I expected it to do.
It may only operate at x1 speeds on some older systems depending on the PCIe port features.
Other Thoughts: Didn't bother using the RAID functionality on this card or installing the special tools. Just attached my disks and left them unconfigured and they will show up as individual drives to the OS. I use mdraid in linux to make my RAID5 and everything works fine while not being married to any particular RAID hardware. I could hook them up via USB SATA adapters if I wanted to get at my data if I really had to.READ FULL REVIEW
This review is from: SanDisk Extreme SDSSDX-120G-G25 2.5" 120GB SATA III Internal Solid State Drive (SSD)
Pros: It is not the fastest performing SSD in its generation, but is not bad either. I would say it is middle-of-the-road compared to other brands of SSD I own from the same generation. Yes there are models with better performance, but at a much higher price. Still blows away a spinning disk.
Cons: It is a bit larger than some other brands SSDs, it is full 2.5" HDD sized device. Might make it tricky to squeeze into some laptops or enclosures.
Other Thoughts: Came with the latest firmware R211 already installed, no problems whatsoever so far. Windows 7 system performance score of 7.4 for the SSD.READ FULL REVIEW
Pros: Heavy, feels sturdy, no fear of tipping over when loaded with drives. Included USB3 and eSATA cables. I liked the concept of 2 drive bays in one unit...
Came in a European Connectland branded box with US power adapter inside.
Cons: One of the HDD activity LEDs does not work at all.
USB3 suffers frequent disconnects. No SMART support over USB.
eSATA has frequent errors and results in data corruption. Computer shows it is only connecting as 1.5Gbit/sec even though the stated specs say it should be 3.0Gbit/sec. Both my computer and this unit have JMicron chipsets so I would hope there's no incompatibility between them.
Forget about max linnk speeds printed on box, the speeds are pretty slow. If you are lucky you might hit 90MB/sec (between the errors and disconnects), but if you have 2 drives mounted then you can only go 45MB/sec each. And if you are writing to one drive, it blocks reading from the other drive, so it's easy to get really slow in a hurry.
Other Thoughts: I have not tried the cloning feature as I have had no need for it.
I am using Linux. I have a few other USB3 and eSATA adapters and enclosures from other brands which do not suffer these problems, so I'm fairly sure it's not a problem on my PC, but you never know. USB3 in particular has a bad reputation, but at least the eSATA should work reliably and at the advertised link speed!
In hindsight it would be faster and more reliable to just buy 2 cheap USB2 hdd adapters and run them in parallel.
Overall this unit was a massive disappointment and it has been collecting dust as I'm afraid to use it and ruin my data, and would feel ashamed to resell it to someone else knowing that it does not work properly.
I bought this when it had zero reviews, and I waited beyond the return period before trying it, so lesson learned.
