Xbox 360 Storage Showdown: The Flash Factor

Arc System Works' one-on-one fighting game Battle Fantasia weighs in just 1.2GB, meaning it could easily fit onto all of our test drives, but with an added sting in its tail: the game comprises of exactly 2,140 files on the disc. Flash drives are notoriously bad for handling tiny files, so let's see how our test range fared, up against a standard Xbox 360 install onto the conventional hard drive.

It turns out that the test wasn't just a challenge for the flash drives, but also for the SSD too, with a surprisingly strong showing from the USB HDD. Regardless, bearing in mind that the size of the overall package was very close indeed to the Forza demo's, throughput was massively reduced. Perhaps the fact we were installing from DVD is a contributory factor, but clearly handling those 2.140 files produced an enormous variance in performance meaning that the USB devices themselves were the main bottleneck.

Note that the MicroSD card, designed for handling small files, easily out-performed two of the three USB flash drives, which suffered horribly under the load. Our favoured price-performance champion, the 16GB ByteStor, still managed to hold its own, easily thrashing everything but the SSD and the USB HDD, and still remaining within spitting distance of those more pricey competitors.

With that, it's time to jettison our 2GB and 4GB Flash drives, and instead move onto more prolonged testing with three carefully chosen games. In our original NXE DVD vs. HDD Face-Off, we found that Valve's The Orange Box produced extraordinary speed gains when installed onto the hard disk, and conversely, we discovered that Halo 3 performance was actually impeded significantly. So these two games, showing the best and the worst from hard disk installation, would form the basis of our next salvo of testing.

First up, let's see how the games stacked up in terms of the base installation times, factoring in size of the install and the amount of files, similar to the Battle Fantasia test.

Install Halo 3 from DVD (5,835MB, 167 Files)

So, fairly uniform write rates in these two games, with clearly faster transfer rates compared to the file-heavy Battle Fantasia. With that, let's take a look at Halo 3. In the original Digital Foundry NXE DVD vs. HDD Face-Off, this was the only game that didn't see any improvement over DVD loading speeds. Indeed, there was something of a notable increase.

We re-ran the tests on our standard 120GB HDD for the stats below, but it's worth pointing out that we also had the HDD attached as well as the flash drive (though the NXE HDD install was deleted when it came to testing the other devices). We'd have preferred to remove the HDD completely, but there appears to be a weird bug with Halo3: once you install the game, your save game data completely vanishes from the HDD. This meant we couldn't transfer our saves across from the HDD onto the destination devices, which might have made for a more interesting test - and one that would probably be fairer to the 360 HDD.

Bungie's sophisticated caching system made heavy use of the hidden partition on the Xbox 360 hard drive. Installing to that same drive caused a whole bunch of unnecessary HDD to HDD transfers resulting in significant performance drops. With the inclusion of the USB devices, these multiple transfers still occur, but the data isn't being streamed to and from the same drive any more.
