      This is actually a month old, but I have not seen anyone mention it yet.

        These will provide an incredible amount of storage. Good to see that higher capacity drives are coming though rebuild times in RAID arrays are likely to be very long with drives of those capacities.

            Yes, especially with parity RAID arrays. A large RAID 6 of 10TB drives would be very painful. The throughput doesn't increase like the drive capacity does so the rebuild / resilver times just get longer and longer.

              This is the exact reason that I think parity RAID systems are extremely outdated and dangerous.

                @nadnerB yes, as spinning rusts gets bigger and bigger at a faster pace than you can ingress and egress data to those drives parity arrays will simply move farther and farther away from being an option. In the past year we've seen people with resilvers that were expected to take over a month! And that was with 3-4TB drives. These are more than double that!

                  @scottalanmiller Why can we just not move towards larger SSD's? why are we still pushing the boundaries with spindles?

                    Because spindles are still quite a bit cheaper in terms of cost/GB. We still have a fair amount of time before SSDs come close.

                      Cost. You can go buy bigger, faster SSDs today. But they are extremely expensive.

                        There are 8TB SSDs?

                          We've had 4TB since May. 8TB expected shortly. 2015 is the year when it is expected that SSDs will be larger than spinning rust. Late 2014 is the expected inflection point. SSDs might still yet pass spinning disks this year. The 10TB drives are not on the market yet.

                            Still, those have to cost between 5 and 10K for each drive.

                                    Where is the use case for a drive that large that costs that much? Wouldn't it be less expensive and quicker to get a stack of 7.2K 2TB drives in a RAID array?

                                      Probably in space, power and cooling savings, not to mention performance - but I'm more wondering, do people run those things in RAID 1? 60K DAMN!

                                        If you need a million or more IOPS in 1U but need storage capacity, it would be the one choice. To hit similar IOPS from 7200 RPM drives would require roughly 8,000 drives in RAID 0. At 8K drives, you'd be looking at a drive failure every several hours, couple days at best.

                                            Believe it of not, it's cheaper to buy that card than to get the same IOPS from other drive types. Even using the cheapest drives you could find at $60 a pop, 7200 RPM drives would cost $480,000 to purchase and a lot more to put them in chassis, and a lot more to get the horsepower to handle the RAID and that's before we consider power consumption and cooling.
