Sony revealed additional details about its PlayStation 4 game console at the Game Developers Conference. One of the major improvements of the PS4 will be its storage sub-system, which will include faster Blu-ray disc drive as well as very hard capacity hard disk drive. Both will improve overall user experience by speeding up game installations and launches.

The PlayStation 4's Blu-ray disc drive is three times as fast as the PlayStation 3's, according to Engadget web-site. Keeping in mind that the PS3 is equipped with 2x BD drive capable of reading Blu-ray discs at up to 9MB/s speed. The three times faster solution is a 6x BD drive that can read discs at up to 27MB/s, which should be enough not only for modern games, but also for next-generation 4K video discs, assuming that they are Blu-ray or compatible with the drive (or use the same 405nm wavelength as BD). 

Today’s PlayStation 3 systems are available with 160GB, 250GB, 320GB and 500GB hard disk drives. They PlayStation 4 is projected to feature “a very large hard drive in every console”, revealed Chris Norton, a senior staff engineer at Sony Computer Entertainment America, reports IGN web-site. Since the PS4 consoles will likely continue to use 2.5” hard drives, it is possible to expect 500GB, 750GB or 1TB HDDs in the PS4 simply because there are no standard drives in such form-factor with higher capacity now and Sony is unlikely to use the forthcoming drives based on newer platters in the consumer electronics device. 

Other hardware related improvements that the engineer mentioned are all-digital buttons and sticks on the DualShock 4 controller, ability to charge the controller while the console is off as well as a mono headset in every PlayStation 4 box.

Sony PlayStation 4 is based on a semi-custom AMD Fusion system-on-chip that integrates eight AMD x86 Jaguar cores, custom AMD Radeon HD core with unified array of 18 AMD GCN-like compute units (1152 stream processors which collectively generate 1.84TFLOPS of computer power that can freely be applied to graphics, simulation tasks, or some mixture of the two), various special-purpose hardware blocks as well as multi-channel GDDR5 memory controller. The PS4 will come with 8GB of unified GDDR5 memory sub-system (with 176GB/s bandwidth) for both CPU and GPU as well as large-capacity hard disk drive.

Sony PS4 will be equipped with Blu-ray disc drive capable of reading BDs at 6x and DVDs at 8x speeds, USB 3.0 connectivity in addition to a proprietary aux port, Gigabit Ethernet port, 802.11b/g/n Wi-Fi, Bluetooth 2.1 EDR wireless technology as well as HDMI, optical and analog outputs. The new system will also utilize new DualShock 4 game controller with integrated touchpad as well as better motion sensing thanks to new PS4 Eye tracking cameras.

The PlayStation 4 is projected to be launched during holiday season 2013 in select regions.

The most important parts of the storage sub-system are:

1) SATA 3 native support
2) Ability to upgrade the HDD to any after-market 2.5 inch drive, including SSDs.

This gives the most future-proofing for upgrades/speed and flexibility to buy next gen drives over the life-cycle of PS4 without being stuck with MS's proprietary overpriced HDD upgrade model.

Over the next 5-10 years, SSDs will get larger, faster and cheaper. What size HDD PS4 ships with now doesn't matter as much as having points #1 and #2 covered. In reality, it would be better if PS4 shipped with a 250-320GB drive and price was $40-50 lower. Initially PS4's gaming library will be very small. Once the game library builds up, we could just upgrade the HDD to a faster/larger model in 2-3 years once 250-320GB is insufficient. Launching with 1TB sounds impressive at first but long-term it's actually worse since you are paying upfront for space you don't need and over time when you actually do require that much space, HDDs will be much cheaper.

It wouldn't be impossible for the PS4 to be this way. They are already dealing with these issues with the PS3 as that is the way it has been built. The PS3 Harddrive is removable and replaceable with any 2.5 Notebook drive on the market as long as it is no bigger than 9.5mm in height. (unless of course you modify the drive to be powered externally which I have seen done online). Of course the PS3 isn't Sata 3 but the PS4 might be.

Couldn't agree more. Modular-ness and expandability from a console is a HUGE plus of course although the downside is it opens the once closed-system to tech support nightmares by idiot customers who fcuk up their system due to not researching what goes where. You just can't win with the utterly dumbed-down iCrapple generation.

Looks like a winner through and through.

I thought all digital buttons and sticks were a big negative since they don't do gradual pressure well or at all

I thought the same initially, but then I thought how few games actually used the analogue buttons (the sticks and r2/l2 triggers remain analogue). And if cutting the analogue nature of the dpad and face buttons cuts latency and cost then I'm happy with the change.
