1 out of 5 eggsFailed drive and even bigger fail on data security front

Pros: Big and fast

Cons: Failed within one year. Buffalo offered to replace, but beware: "support analyst" indicated they do nothing to destroy user data before shipping it back to OEM in China. With no way to remove data from the drive, I'd rather eat the $170 than send personal data into a black hole. (I might add that the support analyst was a bit of a jerk.)

5 out of 5 eggsUnderrated. Used for HD Recording

Pros: This External Hard Drive is highly underrated. I record and render video straight to it and it moves along nicely without a hiccup. It is very silent as it spent the first week on top of my desk.

Cons: None

Pros: Very Fast with smaller files

Cons: The USB port is centered so be very careful inserting the cable. The pins will bend out of shape.

4 out of 5 eggsNice drive no on-off

Pros: Drive works well. It is fast and quiet. Average dimension sizes and basic design drive. Of course the formatting really brings all these drives capacities by 10% and this one is no exception. One of the proprietary software is useful and appears to help speed the file copying process possibly due to the large drive cache.

Cons: No on/off button. The drive automatically turns itself on/off with a signal from the computer. Drive enclosure does not appear to be well designed, which is more apparent in the rear connections as it seems to not quite fit well together. I hope it has nothing to do with the quality of the hardware inside. It is made in China, even if the corporate address is in Texas US.

5 out of 5 eggsThis thing is fast.

Pros: Here's the numbers....
Performance was very good, seemed to transfer files well, and especially worked fast on large files (>1Gb)

I ran some benchmarking with CrystalDiskMark and the results, i got back were around 200 mb/s read and 250mb/s write on both sequential and 512k tests.

Real world translation.

Transferring 35 Gb's of music from a 7200rpm WD Internal HDD to the Buffalo took just over 18 minutes and the transfer involved 7800 files.

A transfer from a USB 2.0 5400 WD HDD transferring 16.5 Gb's of Movie files took about 13 minutes.

Here's the good one......transferring a 15.7 Gb System file folder (Rift) from my Sandisk extreme III SSD to the buffalo took only 70 seconds!!!

This drive comes with software included but is not needed to use the drive, just plug it in and it works.

This particular drive's capacity came in at 1.81 Tb formatted.

Construction of the drive seems durable enough, I would take it on the road with me if needed, though it is likely to have a permanent home on my desk.

Drive is silent compared to my gaming computer.

Cons: No on or off switch....and limited to a USB interface. It is backwards compatible with older USB so not a loss there, but this drive could benefit from E-sata connectivity, especially with the 1Gb cache.

The on and off switch is just a personal gripe, at least it doesn't run all the time.

Other Thoughts: My rig is a AMD Fx-4300
Asus M5A99X AM3+ USB 3.0
8 Gb Kingston HyperX 3
256 Gb Sandisk Extreme III SSD (Sata 6.0/Sandforce)
XFX Radeon 6870 DD
Cooler Master 750 Gx PSU
Cooler Master HAF 912 Case

5 out of 5 eggsIt is Faster and Easy to use.

Pros: I've tried a few different external USB backup drives, this one was one of the easiest to install and understand the software. This comes with software selections of eco-manager, disk formatter 2, cache control tool, Ramdisk, Backup Utility, restore tool and TurboPC EX File Copy. I find this to be a very nice software selection and of better use than the others that I've tried.

Great control of when you do the backups even down to the minute and how often.
USB 3.0 backwards compatible, two USB 2.0.
Cache control for the improved speeds and it is fast.
A three-year warranty and 24 seven customer support. That's hard to beat.

You can use this on a PC or Mac and with the 2 TB size. It's a great amount of flexibility for the average user. It seems to me that very few of us even do a true backup process and this makes it easy for anyone to bail to do one. The software is easy to understand and easy for a novice to use, while still having options for those that need it.

Cons: This is able to have a small fan installed in the case, wonder why it doesn't come with one?

Other Thoughts: Even though you can go to the website. There is programming on the DriveStation that I recommend making a copy of for use later on. I saw no reason to keep it on the hard drive while using it for backups. It's a non-restricted hard drive with a really nice backup software package and the unique cache control system that gives the advertised speeds. I got curious when I noticed that the TorboPC EX File Copy was the control window when I was transferring data from a different external drive to my PC so I tried a few different cash sizes to see if there was, in effect in the transfer speeds and yes, the more cash, the faster it was. I also noticed that my W.E.I went from 7.7 to 6.0 when I had the RamDisk cache on vs: off. The DriveStation available cache didn't seem to have any effect, though on my FPS during gaming or speeds. I see my computer running at. So depending on your need and how often you backup you can turn up the RamDisk cache amount when you want the ultrafast backup speeds and adjust it lower for incremental backups, gaming, or any other reason. It makes it a little effort, but it also seems to make it simply good options, it's very easy to change or turn on and off.

When set Windows recognizes this and it's awesome that you can control your backups by the hour or down to the minute and as often as you'd like. For professionals and offices. This is a perfect individual backup device and for the homeowner. It's a great way to have a set and forget backup system. Again curious, I asked and found that nobody I asked does a backup. So here's a chance to do backups, easily turn up the speed through cash and get that long time involved backup to be done quicker. I am using

5 out of 5 eggs

Pros: good drive. I was able to achieve over 300MB/s speeds when files fit inside the 1GB cache size.

Cons: earl9094 complained that it's not the standard USB connector when IN FACT IT IS THE STANDARD MICRO USB 3.0 CONNECTOR. yet he claims to have somewhat high tech level...

Other Thoughts: you have to understand that once you transfer files too large to fit inside the cache, your speeds will be limited to the hard drive speed and usb 3.0 limitations.

2 out of 5 eggsNot as fast as expected

Pros: Pretty average for a USB 3.0 drive

Cons: Non-standard USB connector
Buffalo DriveNavigator software feels incredibly dated, like something from the Windows 95 era. And it installs to the root of the C: drive by default (can't remember if there was an option to change this).
In my experience, these drives aren't living up to the hype bestowed upon them by various review sites including CNET.

Other Thoughts: I purchased 4 of these on May 27 to use as rotating backups for my 2x3TB Seagate SATA 6.0Gb/s drives (model Constellation ES.2 ST33000651NS) that are connected via SATA 6.0Gb/s to a Gigabyte GA-Z77X-UP4 TH motherboard.

The DriveStations arrived quickly and were well packaged. The enclosure for the drives is plastic and feels kind of cheap, but I'm sure it will stand up to normal use.

Upon connecting one to a USB 3.0 port on a Gigabyte GA-Z77X-UP4 TH motherboard and prior to installing the DriveNavigator software, I used Windows Explorer to copy ~100 GB consisting almost entirely of large (>100 MB) files from one of the Seagates to the DriveStation. I was disappointed to only average about 140 MB/s with peaks of about 170 MB/s. This test was repeated with all 4 drives and the results were very similar.

I then installed the DriveNavigator software, verified that the motherboard's BIOS was up to date (it was), and verified that Windows 8 was fully patched and up to date (it was). The test was repeated and there was no noticeable difference in write speeds.

As a final test, I connected one of the drives to a different PC that is running Windows 7 Ultimate 64-bit and has an Intel motherboard (BOXDH77DF). I was copying large files from a Samsung 840 SATA 6.0Gb/s SSD drive and once again barely averaged 140 MB/s.

The main reason I bought these drives was for the advertized write speeds. On the box Buffalo shows a write speed of 408.1 MB/s when using an Intel 3770K, 4GB DDR3, Gigabyte GA-Z77X-D3H, and Windows 8 Pro 64-bit. The box compares the 408.1 MB/s of the DriveStation to 172.9 MB/s for a standard USB 3.0 hard drive and 35.8 MB/s for a standard USB 2.0 hard drive.

Since I wasn't even at the top-end of the "standard USB 3.0 hard drive" range, I decided to email Buffalo support. They were quick to reply, but this was their response:

"Thank you for contacting Buffalo Technologies, I apologize for any inconvenience.

We here at the Buffalo support team are responsible for ensuring the basic operation of our devices. There are too many variables for us to accurately diagnose read/write speeds on external hard drives. As such, I'm afraid I can offer no suggestions on how to improve the performance of the unit."

I can understand their point, but they could have at least suggested something to try. Like trying a 3rd party file copy utility like TeraCopy (which is something I plan to try when time permits). And it's not like my test environments were totally different from the one that apparently achieved the 408.1 MB/s write speed.

To anyone considering this drive for the advertized write speeds: don't expect any help from Buffalo support if your results fall short of their claims.
