I'm also in the market for an upgrade. Too many games! Thank you for all the great info :)

@JLHardesty - I've used both a hybrid and an SSD (with the SSD currently installed), and I can tell you that the impact for either is minimal due to the PS4's SATA II interface bottleneck and generally slow disk I/O. I save a few seconds here and there with booting up and Destiny load times, but its nowhere near as fast as if Destiny was running on a PC w/ SSD. If you happen to need a bigger hard drive anyways, get a hybrid - but I'd recommend against upgrading only for minuscule gains in speed - or at least google the measurements various people out there have made and judge for yourself whether it is worth it to you.

Hi. I've got a 4tb hybrid drive in an orico external esata enclosure. It's an easy mod to run the sata lead inside and out of the back top vents....very easy... Runs like a charm. Youtube it. I'm new to this site.. And I'm level 27 titan So I'm looking for friends to go online with.If your willing.My ps4 gamertag is at the top. I'm from the uk.

I've seen video comparisons on Youtube of 1TB hybrid drive and a 1TB 7200 RPM standard drive and there was no noticeable difference in the speeds. The hybrid was only a fraction of a second faster. Personally Im going to hold off on upgrading because I really want a minimum of 2TB but would like even more. One Can Hope!!!

I recently upgraded to a 1TB HDD. It's 7200 RPM, so it's better than stock... Right? Anyway, from what I've read, the performance improvements in going SSD are negligible compared to the cost. I therefore went for size and cost. Paid $65 on Amazon for the HDD and it turned out to be the same brand as the stock (something Japanese). I recommend going for size, not speed. Also, upgrading his stupid easy.

[quote]Has anyone done or looked into upgrading the PS4 hard drive? I am debating on upgrading the standard 500GB HD for a 1TB hybrid drive. The hybrid would be around $150 and should speed the PS4 boot time and loading of games. I love my Solid State drives in my PC and now how much of a difference they can make, never really been a fan of hybrids, but think maybe they would be perfect for a PS4, since I don't want to drop $400-$500 on a 500GB ssd. Reviewing speed differences, the hybrids are just slightly slower the full ssd.[/quote] I was looking in at the same thing, that ign comparison really helped, thanks brother I'm Goin with the seagate.
