Benchmarking Hard Drive Upgrades
The days of firing up your console and jumping straight into a game are gone. Now, you have to power up, boot to the operating system, and then start navigating around (sounds a lot like your computer, right?). Fortunately, that makes boot time a great point of comparison for wildly disparate storage devices.
Sony equips the PS4 with a fairly slow stock hard drive. Boot times improve by 23% with Kingston's SSD installed, 15% with Seagate's SSHD plugged in, and even 9% when we upgrade to a 1 TB Western Digital Scorpio Blue we had lying around.
Despite the percentages, though, we're only looking at a five-second boost, tops, which isn't a huge number.
Next, we go for a couple of game installs, which is a mandatory process for any disc-based title.
In most cases, storage technology makes absolutely no difference, since you're constrained by the read performance of the Blu-ray drive. If you're hoping start playing sooner with a hard drive upgrade, you'll be disappointed.
Loading a game from the PlayStation 4's UI to the title screen is mildly faster with Kingston's E50 SSD installed, compared to the stock Spinpoint M8 500 GB. The same goes for Seagate's SSHD. But in absolute terms, the experience is imperceptibly similar.
The Western Digital drive, in fact, ends up being a bit slower, though again, not by an amount you'd notice. It's really only worth upgrading for more capacity, in this case.
Despite those tiny performance differences, you're still stuck watching several splash screens before you can get into the game. Let us skip over all of that, Sony, and we'll be happy.
The biggest gains comes from loading an existing game save, which might be what you end up doing most often anyway.
For this test, I used a save point in Assassin’s Creed IV: Black Flag with a few hours of gameplay ahead of it (in Tulum, in case you're interested). Kingston's E50 SSD and Seagate's SSHD perform identically, improving performance compared to the stock Samsung Spinpoint M8 by 33%. I'm not certain that's worth losing capacity in the case of the SSD, but Seagate gives you the bump up in speed and capacity.
Unfortunately, our two-year-old Scorpio Blue turns out to be slower. It turns out that not every upgrade is good for more performance.
Over time, Seagate's solid-state hybrid drive design is supposed to cache hot data (the stuff accessed most frequently) in its 8 GB of MLC flash. In order to better gauge whether the previous chart's performance was truly representative of the SSHD incorporating our save game data into cache, we ran an extended test of this technology.
Loading the same game file 10 times, restarting the PlayStation 4 after each run, we see performance varying significantly. Even the worst run is faster than Sony's stock mechanical drive. However, I wouldn't say it's clear that SSD-like behavior is to thank.
To ensure that Sony's Blu-ray disc check process wasn't adding variance to a benchmark that should have only gotten faster, we purchased a digital copy of Assassin’s Creed IV: Black Flag on the Playstation Network and ran the test 10 more times. The results proved fairly similar.
The first three runs demonstrated quite a bit of difference, favoring the disc-based installation. But the repetitions after turned out to be quite even.
