Works well under Windows 10.  Much improved back-up speed on my old laptop (HP 2540P).

Worked well. Matter of fact, I'm using it at this very moment. Made my life easy on an upgrade from Windows 7 to 10. Really, the only way to do this is buy a cool SSD drive like this, re-install, and use the old drive as USB backup.

Overall, I really like this external Harddrive.  It was not without initial problems however.  In my case I needed to replace the first one delivered because it was dead out of the box.  Amazon sent another with expedited shipping and that one works fine to date.  I use it for PC backups with eSATA connections between it and my PC.  It's a little tricky using this connection type however.  What needs to be done is to connect everything up first with the PC powered off.  Then turn on the power to the Fantom Drive next and then power up the PC.  When the PC boots through Windows the external drive is recognized in a new directory.  I use Acronis software for backup and everything works like a charm.  Very, Very fast backup.  The Fantom drive also has a USB 3.0 connector which is also nice.  My PC allows hot swap of USB connections so using Windows to mount and dismount the drive in USB mode is a bit more straight forward if you're a novice.

This four drive enclosure is fairly nice and it offers very fast data transfer speeds. In Windows 10 I'm getting about 175MB/s write speeds when copying files from my computer's SSD drive via the USB 3.0 port. Read speeds from the installed drives are also very fast at around 210MB/s when copying files from the drives onto my PC's SSD drive. Each physical hard drive gets it's own drive letter(s) depending on how it's partitioned. Contrary to what others have posted it's not just one single logical drive...ie it's split into multiple logical drives. The built-in fan is not silent but it's not very loud. It also doesn't rattle which is good. The four rubber feet keeps vibration down and also prevents the unit from sliding around. I've setup my drives to not go to sleep often but it does sleep when my PC is put into sleep mode. The power lights and fan stay on in sleep mode but it's not a big deal since the fan is not very loud and I doubt it consumes much power. The only things I didn't like about this enclosure are the doors/latches....they are plastic and kind of flimsy. They also don't click/lock firmly but instead feel squishy. Also the metal body on my unit bows out on the left side.

Update: So today I installed a 3rd drive into this enclosure...a 256GB SSD. I powered down the PC and also the enclosure after the disks spun down, added the SSD and powered the enclosure back up as well as the PC. Upon entering Windows 10 I go into My Computer and none of the 3 drives show up. I then go into Disk Management and see the SSD show up and also one of the other drives but it doesn't have the old volume name and it's now completely RAW. I just lost about 3TB of data! What a POS this thing is.

Update: Purchased Seagate's Data Recovery software and was able to recover 95% of my data. I think in the future before adding any new disks, I'm going to eject the existing drives first as a precaution then once the enclosure recognizes the new drive, I will add the old drives back in.

Update: It's been working great so far...very reliable once the drives are installed and recognized. I currently have 3 SSD drives and one standard HDD installed in this enclosure. No issues in Windows10...sleep and wake works as it should. Now that I'm familiar with the quirks of this enclosure I would not hesitate to buy another.

I bought a Western Digital WD10EALS Caviar BLUE harddisk last week from a local retailer to upgrade my old 320GB Western digital disk.

There was a problem with the initial harddisk I bought which turned into a 32MB hard disk after successfully partitioned and formatted it. After tested by the retailer, I got a replacement.

However, the replacement harddisk works perfectly and is much quiet and more fast than my old 320GB disk. Overall, I am happy with this harddisk and it seems the Blue range does perform as what it is claimed to be - Performance + Reliability ("Reliability" needs to be verified by the time).

I give it for 4-star because of the initial issue, otherwise I believe it is worth for 5-star.

Worked fine for restore drive for windows 10.  Nothing fancy here, but 16GB for $6 is pretty good price.

with windows 10 on it, it's pretty much perfect..

Works as promised. Quick plug and play on my Win 10 Home OS (no need to use install disk per directions), and I am now seeing 20-23 mbp/s of my 25 mbp/s service, compared to the 10-14 mbp/s I was getting with my old adapter.

Perfect for recovery drive for Windows 10 system.

Works fine, once I installed a 128GB microSD card and sym-linked "c:\Program Files" and "c:\Users" to the external storage.
Runs Windows 10 like a charm.

I have this drive and also the 500GB version, connected to two different PCs each running Windows XP Pro SP2. Both drives are excellent although I will mention one caveat below about this 1 TB unit.

I have not experienced any of the problems mentioned in other reviews about booting or DOA. I wonder if the person with the boot problem reformatted the drive as a system drive or had other problems in BIOS setup.

The drives both installed easily and automatically. They come formatted for FAT32 which makes them compatible with earlier versions of Windows although it limits file sizes. Windows Disk Management easily reformats them to NTFS. Although the reformat takes several hours. You can continue using the PC itself, though, while the reformat proceeds.

Something unusual about the USB2 and eSATA interfaces. I tried the USB2 interface on both drives. I also tried the eSATA interface - in one case connecting to an eSATA port through a PCI card (and the PC has a 33 MHz PCI bus, not a 66 MHz PCI bus) and in the other case to a PCIx PCI Express interface. In both cases (!), the USB2 interface provided faster throughput than the eSATA interface. I believe the limitation is inside the PC, and NOT inside the drive. Nevertheless, it transfers about 1.6 GB in about 2.5 to 3.0 minutes. Plenty fast for my use. I now use the USB2 interface.

Note that the fancy although difficult to interpret white LED display in the front of the drive works with USB and FireWire although not with eSATA.

The 500 GB drive is super quiet all the time. The 1 TB unit is a bit odd. After accessing it, some time later it will sometimes make a low-level rapid clicking/whirring noise until the drive is again accessed at which time the noise stops. I actually replaced the 1 TB drive through WD and both drives did this. The drive passes the extended diagnostic test and WD says I am probably hearing a normal noise. I took it off the desktop and put it on top of the mini-tower so the noise no longer bothers me.

I use Acronis software to do disk image backups with these drives and also do simple backups of user folders through Windows. The drives makes this so easy.

I wholeheartedly recommend the 500 GB drive and also recommend the 1 TB unit although be aware of the possible noise.

I needed a back-up drive that would work well with the built in backup solution naive to Windows 7.  This little drive fills the bill.  All I had to do to install it was to take the drive out of the box, plug the included short USB cable in to my PC and wait for Windows to recognize it.

Then I went to the control panel and navigated to back up and did a full image and backup of my PC.  Now my PC is incrementally backed up automatically every day.

The drive is very quiet and read/write speed seems to be fast.

I used it to replace my internal HDD with a SDD. The speed increase is solid and it feels to be on par with my Windows 10 machine. There I have an internal 512 SSD on a Sata interface. Gave a second live to our Mid 2011 iMac.

The transfer speed is good and the device is quiet. You cannot beat the price per gigabyte. There are a couple of gotchas which may not matter depending on your backup needs:
1. Windows Backup will not work if using Windows 7 or earlier due to an incompatibility.
2. The included backup software does not backup hidden files, so if you're expecting and automatic backup of your Outlook PST file that has all your mail, look for 3rd party software.

As an additional drive to store all your stuff you don't have room for, it is perfect.

Works great so far and no complaints other than I don't like Windows 10, which is not the computer's fault. I got the 256SSD, so it powers up within 5 seconds, which is incredible.

Great product in a nice packaging. Windows 10 now boots significantly faster at twice the usual speed and my 250gb is almost filled to its maximum capacity. Transfer speed was lightning fast as well and no errors was found when duplicating using the software. It will be perfect if they can supply the cables for purchase as well.

Great!  Not that Windows 10 still has a problem with video overload and freezes to this day.
