Pros: I ordered (2) of these in a recent combo deal and paid under 200 bucks for both w/free shipping and that included a 32 GB USB 3.0 flash drive with the deal. The packaging was excellent. I am running these in a Windows 7 Pro as a mirrored volume. Each drive is reading/writing at about 180 MB/second. There are zero bad blocks on either of these drives. Flawless. They are considerably faster than most 3 TB drives and temperatures have been cool never over 31C. 3 year warranty where else are you going to get that these days at this price? The OEM Toshiba drives are only 2 years.

Cons: no SATA cable or screws for a "retail kit" but in fairness the description does mention that. Price varies from day to day so wait for a sale on these.

Overall Review: Drives show up as Toshiba as the device ID of course they are re badged Hitachi. People who have had problems with the OEM bare drives from Toshiba sold here, well that has more to do with newegg's sloppy packaging than it does with the quality of the drives. Lately newegg has cleaned up its act and is even packaging the bare drives better. But if you are spooked by the bare drives pay a few dollars more for these in the retail packaging. I have no idea why the Toshiba drives are being sold at a discount to WD and Seagate drives maybe it is because Toshiba just bought out Hitachi and are eager to move some product.

Pros: Case itself is OK and looks decent

Cons: Power supply no good

Overall Review: Small office build with just a 77 watt TDP Intel i5 and no graphics card, with one SATA SSD preinstalled with Windows 10. System booted and ran fewer than 5 minutes blinked/stuttered and shut off. Would not restart. The Rosewill piwer supply rated at 400W could not power a 100W system for 5 minutes before crashing. Put in a good power supply of my own, and system works. Rosewill should replace the bad power supply.

Pros: Legendary HGST enterprise drive quality backed by real user experience in data centers. Fresh, New current model and recent build dates. Mine is dated July 15 left the factory. Very low power consumption half of the other HGST Enterprise drives Of course zero bad blocks and no SMART errors at all This particular model is the #1 related most reliable hard drive in Backblaze statistics. 0.0% annual fail rate for Q1 16, 0.4% AFR for Q2 16. This is data since April 2013 running 24 hours a day 7 days a week As close to new as can possible: Mine only has 48 hours "power on time" when I got it. Half the price of a new one Fast: > 135 MByes/sec read AND write speed. Burst rate 165 MB/sec Cool running 31 C not even warm to the touch Dead silent no sound whatsoever

Cons: Slightly less fast than the 7200 RPM models 135 MB/sec vs 145 MB/sec a tradeoff for silence, cool running and low power 90 day warranty oh well it's a 'refurb'

Overall Review: Excellent buy half the price of a new one and mine had only 48 hours of use; including refurbishing/rezeroing time about half that. Most pristine refurbished hard drive I have ever seen. This is a bare drive OEM drive. no cables no box, no screws. You probably knew that but I will mention it. By the way I know the difference between a 'we zeroed out the SMART data to make a refurb appear new" versus the HDD actually has zero to a few dozen hours on it. Basic tools can be fooled but the self test logs never lie Considering that is took more than 10 hours to check for disk errors and about 10 hours to low level format, about 1/2 of the 48 hours of one time would have been spent zeroing out the disk before selling to to me. So this disk as actually "used" for just 1 day Backblaze tested almost 9,000 of this exact model running 24 hours a day 7 days a week since April 2013, and this HGST model I am reviewing has the lowest failure rate of any hard drive ever tested. 0.4% a year fail. Compared to some of the 2 TB refurbs that are upward of 50-60 these days, this 4 TB and a brand new model with essential no hours on it for 99 is fantastic. Some of my 2 TB refurbs have 25,000-33,000 hours on them not 48 hours. As with all new drives or refurbs I recommend HD Tune to scan each block of the hard drive for errors take over 10 hours, then a full not quick Windows format takes nearly the same time. After that each and every block of the hard drive has been exercised. Highly recommend, get these while they last at this price. I bought 2 which meets my current needs. UPDATE: I bought 2 more for a total of 4. The most recent purchase are from the same batch and both had just 49 power on hours, on them.

Pros: No bad blocks Got lucky, 25,000 hours not too bad for a refurb. Some do better. Do you feel lucky today? Will likely outlast a brand-new desktop class hard drive by quite a lot especially a Brand S or Brand W Feb. 2012 manufacturing date one of the newer ones (relatively speaking) for a Hitachi refurb Fast: >155 MB/second transfer rate in a USB 3.0 docking station; more than adequate Very fast: access time 10.8 mSec superb drive for random access to files/data Not buggy: no errors nor glitches whatsoever with this model Hitachi hard drive Enterprise quality: side by side with a desktop drive the desktop ones seem flimsy next to this Hitachi Decent warranty: 90 days replacement when HDD is bought directly from Newegg Quiet enough for office use. For refurbs these ones from Newegg are good: fairly low hours and fairly recent build dates

Cons: Hot running if running in lay-flat USB doc 52 C Only use the vertical style docking for this hard drive then that are 37 C Frequently out of stock, prices fluctuate on this item and when out of stock it redirects to 3rd party sellers who charge more for the same thing.

Overall Review: I am writing about product number 1Z4-001J-00078 that I bought directly from Newegg. They are frequently out of stock and when they are, your search takes you to the same drive sold by goHardDrive. They are a good, reputable company and offer a 1 year warranty. If stuck with a 3rd party seller I use them. Part number 1Z4-001J-00078 directly from Newegg costs less and has a 90 day warranty. Recently they were on sale for 30, then out of stock, then the price went up to 40, and now out of stock again. Supply fluctuates at least at the low price you and I want to pay for this thing. Mine arrived with over 26,000 hours on it but only about 20-30 power on cycles. These drives run very hot in a 'lay flat' style USB docking station. If you run it in the 'vertical mount' style dock though the temperatures are very good. Only 37 C. In the flat dock it was heating up to 52 C. That is a huge difference. This hard drive requires a lot of cooling air. At 30 these were a very good deal I was lucky enough to get one. At 40 an OK deal, I just bought 1 more for that awaiting delivery. After this I will just stop buying until the price drops back to 30. The 90 day replacement warranty when the HDD is bought from Newegg is enough. You know these were not early deaths because the drives have nearly 3 years of usage on them already. But they can get damaged in shipping and fail slowly. Make sure you thoroughly test these drives: I suggest the HD Util utility's block by block health check first. Then run Windows formatting on the drive using the extended formatting not quick format. That runs for 3-4 hours but writes every block on the drive. Then after all this check that there are still 0 reallocated blocks and 0 pending blocks. If all is good, you have a very good hard drive that should have quite a bit of useful life left in it, for a little money. If you drive has a lot of motor whine is noisy or has bad blocks or will not format RMA the darned thing -- don't complain about it. It was damaged in shipping. Newegg will take care of you. There are brand new drives for example brand S that are 10X worse reliability than Hitachi. When the price on these goes up to around 50 to 60 or more range though, then it is no longer such a good deal; you can find refurbished 3TB HGST drives for just a bit more money including some of the newer 7K4000 series. If have seen the 3TB going for around 62 to 68 range. Or another thing to consider, I bought a brand new, unused HUA723020ALA641 for 78 with free shipping in the original factory sealed packing. Not a refurb, not used, brand spanking new. Or new old stock, if you want to call it that; they have zero hours on them.

Pros: Good price when on sale got Shell Shocker deal 3 for 27 back in June These seem more reliable than the similar Voyager Slider X1 model of 32GB not sure why 5 year warranty and Corsair honors it (see below) Fast reads and writes when you use USB 3.0 Corsair one of the best companies in the industry to deal with regarding customer services

Cons: Does not really lock open or lock closed Keychain holder nub on the end of it is very flimsy and easy to break off SUBSTANDARD. You will lose one off your keyring, in time. A bit slower than the Slider X1 model but not by much

Overall Review: I am running FREENAS on one of these and it runs like a champ. There are some advantages of running FREENAS from a bootable thumb drive as opposed to one of the hard drives in the NAS. Very snappy performance from this model. These do not state a performance number but in my experience are very close to though a bit slower than the Corsair Slider X1 model. However the X1 seems a lot more finicky and less reliable than the regular Voyager Slider I am reviewing here. I had a 64 GB Corsair Voyager Slider go bad on me about 3-1/2 years into the 5 year warranty. I did not even have a receipt just had the item number off the original package. Corsair cheerfully sent me a replacement at no charge under warranty. All Corsair slider have a key ring attachment you can see it in the 4th photo. You can attach it to a keyring and carry it around in your pocket with the keys. However these are a cheesy and week non-reinforced nub of plastic. Just though normal use and keys jangling around in your pocket this USB thumb drive I practically guarantee, will bust off your keychain. I my keys on my belt and it busted off and just blind luck I looked down and the Slider was a couple of steps behind me. Since these are meant to be carried around with you the mechanism is quite cheesy and not up to Corsair's high standards.

Pros: It works great and the actual disk manufacturer and model number shows up when you run HDD testing software like Crystal Disk Info, HD Guardian, WinDFM, HD Tune and the like. Some other brands of dockjng stations identify as the docking station itself instead of the hard drive. Does not slow down the drive. This makes it good for testing new hard drives before installing them. It alsk works good as a backup device. Holds the drive firmly in ace.

Cons: USB cord is too short compared to other brands. The plastic case seems a bit flimsy compared with some other brands.
