External Hard Drives

From Mac Guides

Jump to: navigation, search



After Taking Part in Numerous Threads and Purchasing Numerous Drives after Research, I have come to a couple of suggestions and a massive "guide." This guide has mainly been complied by thegoldenmackid. If you have any questions about this guide PM me, if you have questions pertaining to a specific drive – please don't PM me - use mroogle or Google. I encourage everyone to participate, but please keep with the general theme of the guide.

The Basics

There are three main things that will affect the speed - all three are vitally important.

Connection Type

This is the one most people will know about, if they know one. Things like Firewire 800, Firewire 400, USB 2.0, eSata, etc. It comes to how your drive connects to the computer, in general (fastest to slowest) eSata, Firewire 800, Firewire 400, USB 2.0. Firewire is preferable because it is not only faster then USB, but it transfers at a constant speed, whereas USB is variable. eSata is the fastest but it requires a port that is not available without an adaptor, and those adaptors are hit and miss in terms of quality. Chances are most users will do fine with Firewire 800 and have no need for eSata.

Hard Drive Speed

For some reason people seem to forget that if you have 4200 RPM Drive inside your enclosure, it's going to be slow. This depends on the physical drives inside your enclosure. Speed from fastest to slowest: SSD, 7200 RPM, 5400 RPM, 4200 RPM. The higher the revolutions per minute, the faster, unless there are no revolutions at all ;).


The one people forget. The cache is just like the RAM in your computer. It's the place where information is stored temporarily. It is important that you look at this especially if you are going to try to play files from your drive. Even if you are using it is a back-up you don't want a 4MB Cache. With more cache opening larger files will be faster, and accessing the same (small) file consecutively will be faster. The most cache for most stock drives is 64MB.



Apple's Time Capsule is subject to much debate about its longevity. This is currently a "stub" and will be updated with more information soon.

Generation I

Forum user Perrumpo notes owning one for about a year before selling it to upgrade without any problems.

Generation II

Forum user Perrumpo recommends the dual-band version.


DriveStation Combo4 1TB Recommended by techfreak85. Amazon Link

DriveStation™ HD-CXU2 with Full Disk Encryption 1TB Recommended by bsblvnv


Drobo is one of the more popular bulk storage options. Drobo comes in a couple of configurations that allow users to place their own drives inside the unit. In general, users that are using Drobo are looking for 2 TB or more of storage. Because of the nature of the configuration options, each Drobo is different, there is however a mixed debate about the product in general, much of that debate can be found in this thread. A Drobo v. alternative discussion was had here. In general, the Drobo has had positive reviews, but the discussion of the cases of failures combined with the price of the unit sways a lot of users to alternatives. User pprior attempted to switch to a LaCie alternative, but ultimately went back to the Drobo finding that the LaCie produced more noise. The one consistent thought seems to be that DRI (Data Robotics Inc., the maker of Drobo) replaces the drives quick and their customer service is good.

Forum user LizKat has owned a variety of Monsoons


Forum user Kebabselector owns a few Freecom devices and is happy with the performance, even more so after a DIY upgrade.

DataTank 800GB - RAID(0/1/JBOD)/FW400/FW800/USB2

The DataTank comes in a number of differing capacities, starting with the oldest model, 400gb and up to 2tb. The ones that Kebabselector has used are the 800gb versions. The Datatank series of harddrives have been around for a few years now, designed and manufactured by the German company Freecom. The drive unit is an aluminium enclosure containing 2x 3.5inch Sata disks. The device has ports for Firewire 400(1) and 800(2) and USB. Later models of the drive include network ports and wireless (possibly eSata). The Datatank has the option of using Raid 0 and 1 (Mirror, Volume spanning) or JBOD (2 drives). Obviously with mirroring you loose half the capacity, so in the case of the 800gb datatank it becomes a 400gb mirrored device. The software for the drives is easy to use, in fact for most (unless you use the backup software) you do not need to use it once you have configured the drives.

These days 400gb isn't such a great capacity and after struggling to find a solution I decided on the DIY route. Freecom confirmed to me that the Datatank (400-500-800-1000) would suppose drives with a 1TB capacity, so after sourcing some drives (Samsung Eco drives - 5400rpm) I now have 4TB of storage (2 Datatanks with 2tb each). Also worth noting that as the Eco drives run slower it's quieter than before - not that the original was loud.

Update: Looking at the Freecom site it looks as if the DataTank has been discontinued.


It's worth noting the original capacity Datatanks listed above are out of production, however I do see them pop up on Ebay quite often and the information above may be of interest to those looking to get a good quality external Raid HDD on a budget (with a view to updating). Also worth noting that I'm based in the UK as Freecom drives might not be that well known in the US.


G Drive-Q 1 TB

Forum user Perrumpo notes a "horrible" experience with this drive. She notes buying the drive for reliability and it never working consistently. She notes that after hardly using it, constant trouble with it mounting. She notes that the repair was ineffective at solving the widespread problem regarding a part. She also notes problems with the service, nothing that the customer has to pay for shipping to send it in for repair. Perhaps more concerning, she notes that the G-Tech customer service failed at sending her a response to her e-mails regarding the faulty repair. Ultimately her experience left her stating, "I will never be able to trust this drive even if they do repair it again." Amazon Link

G Drive-Quad 500 GB

Forum user RebornKillah recommends it, but it's currently out of production

G Drive Mini Triple 500 GB

Forum user Bill Gates recommends it. Amazon Link

Digital Skunk notes the great warranty; jaysmith, mBox & tcphoto recommend G-Tech.


There are only a few companies that make external hard drives that make their own drives, Hitachi is one of them. Of other interest to users is that Hitachi recently acquired G-Tech, a high-end drive manufacturer.

Tterb recommends.


There is an entire thread dedicated to LaCie, I have summed up support from users below, but simply a tally. The thread lists specific complaints and reading it would be highly beneficial if you are interested in purchasing a LaCie drive.

2Big Triple

Recommended by Digital Skunk & KeriJane. Out of production.


Forum user Bezbozny purchased the BigDiskExtreme II Triple Interface 640 GB. Bezbozny notes that after eight months of owning the drives issues arose with the mounting of the drive which was ultimately traced back to a faulty power adaptor. Bezbozny notes that because of the lack of LaCie service in Greece, the unit had to be shipped at Bezbozny's expense to Germany for repair. Bezbozny notes that paying for shipping and the delay that took place was not great, but the experience with LaCie was good overall.

Forum user VanMac also recommends the BigDiskExtreme. Out of production.

d2 Quadra 1 TB eSATA/FireWire800/FireWire400/USB 2.0

Forum user DarwinOSX notes purchasing a Rocstor drive and having no issues.

PodPacker purchased about 50 of these drives for his/her business without a failure on a single drive. Most drives have been in operation for at least 2 years. What is ideal about the Rocstor desktop drives is that they run quietly and have no external power brick. Their mini drives are just as silent and don't require external power


Seagate makes a variety of external hard drives, some branded for the Mac. Seagates drives are often preferred because they make their own hard disks and the enclosures.

Same as the above drive, just double the capacity. Recommended by pprior & dernhelm. Amazon Link

My Book Studio Edition 2 TB (2010 Version)

Forum user MacDawg (who has religiously recommended Western Digital), notes that the newest version of the drive comes with SmartWare that causes the drive to unmount. While this is a software issue and should be fixed by a firmware update, MacDawg currently does not recommend the drive. Forum user Kebabselector also notes the same issue, while forum user onerob had success with the firmware updates.

My Book Home Edition 500 GB

Forum user slieu92 notes having problems with it shutting down, sleeping and mounting and does not recommend the drive. Forum user senseless notes having similar problems with the hard drive. Amazon Link

Passport Series

The Passport Series are Western Digital's line of portable usb-powered hard drives. They are some of the most popular bus-powered drives on the market and come in a variety of colors and sizes. Recommended by: terp2007, odinsride, Samuriajackon, cluthz, matthewscott661, MikhailT & thegoldenmackid. Amazon Link

Elements SE 1TB Portable Series

The WD Elements SE Portable Series is almost identical to the Passport Series except for one major difference: No SmartWare/Crapware. It is tiny, USB-powered, and ultra-portable. It is also one of the best bang for buck bus-powered 1TB portable drives on the market at $119.99, costing roughly half as much as an equivalent 1TB OWC On-The-Go Pro bus-powered USB 2.0 portable drive which is $217.99.[1] Recommended by: EzhnoWolf.

500GB USB Desktop Hard Drive

Forum user lewis82 bought one of these drives and so far didn't have any problems with it. It might not be the fastest drive around, as the connection is only USB 2.0, but it is more than enough for Time Machine backups. The 7-year warranty (originally 3 years, now extended to 7) is also nice. Model also available in 1TB and 2TB capacities.
