    YES, YES, YES!!!!! PM863 - 3.84TB capacity in 2.5" form factor!!!!! I will buy two and will say bye to all my HDDs :-)

    I don't even want to know what those will cost. But I eagerly await the consumer version at the equivalent size. :) 4tb SSD drives would be wonderful in my NAS, assuming of course that they're priced reasonably.

    I don't use the computer for much more than games so i have to ask. Does that make sense? Isn't the 1Gb ethernet a bottleneck? Do you really need an SSD where you can't even make full use of an HDD?
  • Shadowmaster625 - Friday, January 16, 2015 - link

    There is no consumer NAS that would benefit from an SSD. Yes, its just a waste of money. There is no household usage scenario where a 4TB SSD could possibly be anything but a waste of money. You'd need at least 20 users hitting that thing before it made sense.

    My NAS does double-duty as my virtual machine server. It's great for off-loading battery-consuming and heat-generating tasks like video re-encoding from my laptop (what I use around the house), as well as making sure the browser I use for my banking isn't infected by some web-based malware. It also lets me "run" modern software on ancient hardware I still have (just use remote desktop). It has a 512 GB SSD right now, but I'd been thinking of bumping it up to 1 TB. It's good to know 4 TB will be available down the road.

    Even without virtual machines, using a SSD as cache or even raw storage on a NAS makes sense in certain cases. Most HDDs can only manage 1 MB/s (if that) at 4k read/writes. Add to that the overhead of iSCSI or Samba and networking, and you're down around 0.5 MB/s. I tried offloading some of my game installations to my NAS and this was the bottleneck I ran into, not gigabit ethernet (125 MB/s). Some of the load times were 3-4 minutes for things that would load in 15-20 sec on a local SSD. I tested one game on a 128 GB partition I have on my NAS SSD for fast storage, and it went back to about 30-45 seconds.

    There is tremendous gains from SSD caching, particularly for small writes/reads. IOPS go from hundreds to thousands. And if your workload was heavily biased towards random access (db type stuff), clear win. If we're talking about 4TB ssd to stream movies and mp3s, yes, you're correct. Not compelling until the price is closer and the power/compactness factors get on top.

    For the people doing video editing and can run a faster pipe (10G pci cards as low as $200), it would allow for mirrored SSDs rather than 4+ stripe R0 arrays.

    It would not make any sense in a nas unless it's 10gbe

    FYI you could get sandisk optimus in 4TB capacity for quite some time now.
  • Greg100 - Thursday, January 15, 2015 - link

    In Germany SanDisk Optimus MAX 4TB, SAS 6Gb/s (SDLLOCDR-038T-5CA1) is 4678EUR, but:

    Samsung SSD PM853T 960GB, SATA 6Gb/s (MZ7GE960HMHP) is 538EUR

    So… I would expect PM863 - 3.84TB about 2000EUR.

    Any idea when we will start seeing SATA Express (SATAe) drives? Intel bet on the technology when they released PCHs that supported it. But, as far as I can see, no one is shipping actual drives.
  • Greg100 - Thursday, January 15, 2015 - link

    In Germany Intel SSD DC P3500 Series 400GB, SATA Express 40Gb/s is 600EUR
  • Greg100 - Thursday, January 15, 2015 - link

    and Intel SSD DC P3500 Series 2TB, PCIe 3.0 x4 (SSDPEDMX020T401) is 3043EUR
  • Greg100 - Thursday, January 15, 2015 - link

    The same price is for Intel SSD DC P3500 Series 2TB, SATA Express 40Gb/s (SSDPE2MX020T401)
  • danjw - Thursday, January 15, 2015 - link

    I was thinking a more consumer product. But thank you for pointing that out.
  • Solandri - Friday, January 16, 2015 - link

    Some of the newer laptops and motherboards I've seen list their M.2 slots as being SATA Express-compatible.
  • kenshinco - Thursday, January 15, 2015 - link

    When can we get this in the US?
  • kwrzesien - Thursday, January 15, 2015 - link

    Hopefully never.
  • Greg100 - Thursday, January 15, 2015 - link

    September, don’t worry, be happy ;-)

    I'm curious how Enterprise RAID will be handled in the future. Its likely that SAS and SATA are dead ends for interfaces. There doesn't seem much point, when compared with something like M.2, which is only limited by PCIe speeds.

    The Only problem I see, is that there is no easy way to provide hardware RAID on anything PCIe based. If you wanted to do something like RAID 10 in a server, and you run Windows, you are a out of luck. Are there any solutions planned for this? Something like RAID 10 in a server environment is important, because you get very high fault tolerance and will likely need to stripe SSD's to get any appreciable space.

    Honestly, I don't think RAID has much longer to live, maybe a decade more. We've already seen hardware RAID give way to software RAID. That is, instead of having dedicated hardware which gloms multiple physical drives together, adds redundancy, and shows it as one virtual one on the ISA/PCI bus, it's now almost always done in software at the operating system driver level.

    The next evolution is to filesystem-based redundancy, like ZFS and btrfs. Where the filesystem knows you have multiple physical drives and creates virtual partition(s) around them. These are much more flexible than software-based RAID. (e.g. if you have two 4 TB HDDs and two 3 TB HDDs, you can create the equivalent of one 3x4 RAID 5, and one 1x2 RAID 1.)

    One of the advantages of filesystem based redundancy is that it's agnostic to hardware. I use ZFS on my server and if I wanted to, I could make a redundant volume comprised of a HDD, SSD, USB flash drive, and networked SAS drive. I mean it would be stupid to do so because of the speed differences, but the point is that you can. So the capability to incorporate PCIe-based SSDs is already there if you're using ZFS or btrfs.

    zfs is software raid + file system. spell out the acronym - redundant array of inexpensive disks. Still true. Now hadoop or gluster - that's a different game. Not expecting it to take over the home space, but I have thousands of such servers at my company.
  • cottington - Monday, January 26, 2015 - link

    When you say "We've already seen hardware RAID give way to software RAID" can you give some examples? I'm not questioning your assertion, just genuinely interested. I am aware of Storage Spaces. I wonder if you have you had experience with other software RAID solutions in small to medium Windows environments?
