Vista, OS X updates could bring significant SSD speed gains

It's been a real roller coaster ride of emotions with SSD. The once lauded (at least in our hearts) savior of all things computing has, in real life, provided us with lackluster and even controversial performance gains, while battery improvements haven't been revolutionary and the prices still aren't exactly wallet-friendly. Most of that is unlikely to change in the next couple of years, but there's still plenty to be fixed in the short term. Samsung is working with Microsoft to define optimum packet sizes and best practices for reading and writing files to SSD as a potential update for Windows Vista, which is particularly optimized to work best with traditional hard drives. Sun is also working to improve SSD support with its next-gen ZFS file system, which in addition to powering its Solaris OS should be making an appearance in Mac OS X 10.6 Snow Leopard, at least in the server version. There's clearly still plenty of untapped potential in SSD, let's just hope the powers that be figure this stuff out sooner rather than later.

Datto's Z Series: world's first on / off-site backup solution to use ZFS


Datto earned a round of golf claps with its Backup NAS by bringing comparatively affordable off-site storage to the small businesses of the world, but it's giving itself a round of applause with the Z Series. Hailed as the "planet's first on and off-site backup solution to use ZFS," these units provide up to 1TB of local and off-site storage, optional RAID 1 local redundancy, twin gigabit Ethernet ports, OS X / Windows / Linux compatibility and the obligatory rock-solid stability that ZFS is known for. You'll also get a rapid recovery promise, which enables you to sleep easy knowing that your data can be restored within 24 hours should disaster strike. The units range in capacity from 250GB ($499) to 1TB ($1,149), while the required service packages demand anywhere between $35 per month to $1,000 a year.

ZFS file system coming to Snow Leopard server edition


It's been almost exactly a year since we heard any chatter over Apple's adoption of the supposedly rock solid 128-bit ZFS file system, but it appears to be heading into the next version of the company's OS... at least for servers. According to the promo page for Snow Leopard for OS X servers, the redundant, error correcting, dynamic volume expanding format will be available when the new system drops, though there's no mention of whether it will make its way onto the standard version of the software. With data handling that's this tight, our only question is why wouldn't it make the cut?

Apple previews OS X Snow Leopard: scheduled to ship "in about a year"


The next iteration of OS X was mentioned early on during today's WWDC 2008 keynote, but little was said afterwards. Thankfully, Apple hasn't left us completely out to dry, as a recent release gives a few clues as to what Snow Leopard has in store. First and foremost, the OS isn't expected to ship until about this time next year, and just as predicted, it will be more evolutionary than revolutionary. Specifically, it will "enhance the performance of OS X and set a new standard for quality... rather than focusing primarily on new features." Still, we do know that it'll play nice with Microsoft Exchange 2007 from the get-go, provide "unrivaled support for multi-core processors" with a new technology dubbed Grand Central, extend support "for modern hardware with Open Computing Language (OpenCL)," and raise the software limit on system memory up to a theoretical 16TB of RAM. Heck, you'll even find QuickTime X in there. Yeah, we love those new features, but we can honestly say we're looking forward to a nice round of polishing.

Update: Looks like some more solid info has been posted to Apple's page. Head here for more on Snow Leopard desktop and Snow Leopard server (which will include iCal Server 2, 128-bit ZFS support, Podcast Producer 2, the first version of their Address Book server based on CardDAV, and more).

Read / write ZFS beta for Leopard reportedly sent to developers

It looks like the on again off again reports of support for the newfangled ZFS file system in Leopard are on again, at least according to the latest word from Mac Rumors, which is citing unspecified "published reports" on the matter. What's more, this apparently isn't the stripped-down, read only incarnation of ZFS we heard about earlier this month, but a full-fledged read/write version, the beta of which has reportedly already been sent to developers. ZFS, for those not up on their file systems, was developed by Sun and promises a range of advantages over lesser file systems, including storage pooling, block-journaling, and other things that a rare few get really excited about.

Update: Reader skwasha notes that apparently the ZFS Leopard files have been pulled, but produced a document regarding the ZFS dev preview, which states: "ZFS is a new filesystem from Sun Microsystems which has been ported by Apple to Mac OS X. The initial (10.5.0) release of Leopard will restrict ZFS to read-only, so no ZFS pools or filesystems can be modified or created. This Developer Preview will enable full read/write capability, which includes the creation/destruction of ZFS pools and filesystems." So there ya go.

Leopard does / does not use ZFS, part III: it does! (kinda)

Hopefully this is the last time we'll be forced to post on this topic, but we're not holding our breath: now InformationWeek -- which quoted an Apple executive this morning stating the polar opposite -- is reporting that Sun's ZFS file system IS in fact included in Leopard, albeit with a number of huge caveats. According to a company spokesperson seeking to clear up Brian Croll's "misstatement," while HFS+ continues to be the primary system used in OS X, ZFS has been coded in as a latent, "read-only option available from the command line." An IW reader claims to have accessed the system through Disk Utility's Erase menu, and states that "ZFS is only available on non-boot drives on Sun systems, so this is also the case for Leopard" -- seemingly reinforcing Croll's later assertion that Apple is really only "exploring it as a file system option for high-end storage systems with really large storage." So there you have it: Sun's Jonathan Schwartz wasn't pulling our leg after all, even if ZFS fanboys won't be pleased with the (presumably) final word on this.

Apple: no ZFS for Leopard

Much to the dismay of those Macheads who've started hitting size limits in Tiger's HFS+ file system (all ten of you), Apple has confirmed to InformationWeek that Leopard will not in fact adopt the more capacious ZFS alternative as promised last week by Sun CEO Jonathan Schwartz. Senior director of product marketing for the Mac OS Brian Croll told IW point blank that "ZFS is not happening," contradicting Schwartz's assertion that his company's 128-bit file system would be bringing goodies like built-in data integrity and virtual storage to the iMac and friends. Meanwhile, Sun had no comment on the matter. Of course for most users creating an average Word or Photoshop document, this reversal really doesn't mean much, and may in fact be beneficial when we consider the higher processing demands made by the so-called 'Zettabyte File System." For changes in Leopard that are actually, like, real, you can check out our roundup of the new features right here.

Sun says Apple is switching to ZFS in Leopard

You dealt with it when Apple switched you from MFS to HFS, and again you were switched from HFS to HFS+ (and even journaled HFS+), and you'll deal with it again: according to Sun CEO Jonathan Schwartz (whom you may know for his totally righteous pony tail), Apple is going to use Sun's crazy advanced ZFS filesystem when they move users over to Leopard. The material advantages may not be immediately apparent to the average user (when was the last time you whipped up a multi-exabyte file?), but it will do some excellentay things like storage pooling (aka virtual storage), block-journaling, and plenty of other nerdy things about which you can read up on elsewhere. Expect to hear more about this one next Monday at WWDC.
