This is a bit frustrating considering mostly what the device is going to be doing is writing stuff to disk every couple of hours.Īs Anand will tell you, no sequential write is ever really truly sequential, so small block performance is also important. Obviously the Vertex 3 can write way faster than this, but the controller seems to be strained to the limit when making writes. SATA II again proves noticeably faster than the USB 2.0 route, but performance seems capped to around 40MB/s. Reads show a similar, if interesting, story. Connected directly to the notebook, performance is almost 10MB/s faster. Oddly enough, USB 2.0 performance isn’t even limited by the dock, but rather the controller. SATA II here gives a huge advantage over USB 2.0 and comes close to hitting the limits of gigabit ethernet. Some individual tests are even at 100MB/s (800 Mbps), but these are the averages of those 20-100MB size tests. Connected directly to the devices, we can essentially max out gigabit ethernet with 80+MB/s transfers, or just shy of 700 Mbps. I also threw in one test where I connected over WLAN instead of gigabit ethernet directly to the devices.įirst up is sequential read speeds, which aren’t critically important for backing things up (since you’re probably more concerned with write performance) but hugely important for restoring and verifying or indexing backups. I present to you the (probably) first Time Capsule with an SSD inside.įor good measure, I also tested the Time Capsule with the shipping 2TB WD Green, and one of my own personal 3TB WD Greens inside, just to see how platter drives fare.
Next, that same volume when connected across the network to the Airport Extreme using USB 2.0, then the Time Capsule using USB 2.0, and finally installed inside the Time Capsule using SATA II (3.0Gbps). To start, I took a baseline test with my rather generic Rosewill USB 2.0 dock attached directly to the MBP.
In true AnandTech fashion, the disk I chose to use for testing was a Vertex 3 MAX IOPS 240GB SSD, just to eliminate the disk as being a potential bottleneck in the performance benchmarking. sparsebundles inside that, and essentially Time Machine treats the thing like a network attached drive. When using the disk attached using USB however, you have to preformat the drive as HFS+ yourself, but in that case one large partition suffices.

I learned on my own that these backups aren’t easily portable between the two, though you can actually migrate backups off of the Time Capsule to an attached disk by clicking Archive. Regardless, it’s apparent that the architecture for Time Machine on a Time Capsule differs from the external disk method when a drive is attached over USB. Inside APconfig is a file named AFP.reconnect_keys which contains a mysterious unintelligible string, perhaps a hash of some kind or a token used to authenticate clients. I couldn’t find anything inside APswap, at least after a fresh format. So no matter how you slice it, you lose 2.2GB to overhead just from the Time Capsule partitioning things how it wants. You can see these three partitions by running diskutil list on the drive. Doing so and then taking the drive out for inspection reveals three partitions.

It’s almost as if Apple expects people to try to upgrade the disk on their own in the future or to make it easy to service. There are even options for making that wipe take place with multiple passes in case you’re trying to delete some really shady, erm, scientific research.Īnyhow, clicking erase from the airport utility makes the drive usable without the need for any preformatting. The nice part about the Airport Utility is that there’s a one-click erase button for automatically partitioning any drive properly for the Time Capsule. Rather than time the creation of an entire fresh Time Machine backup on each configuration, I settled on measuring performance across the network to the drive using QuickBench while connected over GigE.īefore we go into the performance numbers, let’s talk about changing out drives in the Time Capsule. The Airport Extreme or Time Capsule pops up under devices in finder, and then you can mount specific shares which appear just like a normal volume to OS X. When a disk is attached with USB to the Time Capsule or Airport Extreme, you have the option of sharing the disk like an ordinary AFS or even SMB share with or without a password. So the question now becomes, is it dramatically faster to use the Time Capsule’s internal disk over SATA II instead of a USB 2.0 attached dock? The question is almost rhetorical (of course SATA II is going to beat USB 2.0, right?), but nevertheless we want numbers.

I don’t own a Time Capsule for backing up my singular Mac instead I use a hard drive dock attached to the Airport Extreme over USB 2.0 for that purpose. The next question on my mind was disk performance.
