Take It from a Tech: RAID ≠ Proper Backup

Wednesday, November 16th, 2011 | Author: OWC Stephen

I thought that today I would try to clear up a misconception that I encounter fairly often on the topic of data storage. I’ll start with a couple of examples:

Say a customer is looking for a RAID solution like the NewerTech Guardian MAXimus to store their important information. It’s a fantastic product and certainly a wonderful solution for your backup or main storage, but here’s the important part: when I ask the customer if this is going to be a backup or their main storage, the response I sometimes hear is, “Well it’s a RAID, so doesn’t it back itself up?”

Another scenario that I have seen, unfortunately, is this. A customer calls in because their RAID has failed, and they are extremely distraught because all of their critical information is on it—tax documents, raw footage for a movie in production, irreplaceable family photos, dissertations, you name it. I’ll ask, once again, if this was their main storage or a backup, and I’ll hear back, “Well it was a RAID. That was the whole point!” Article Continues…

Upgrade Your 06-08 Mac Pro’s Internal Bays to SATA 3.0

Friday, October 14th, 2011 | Author: OWC Chris S.

Most of the time, your average Mac has a longer useful life than its PC counterpart. Unfortunately, the fast evolution of technology means that, after a while, that older Mac may seem a little slow and may not be able to take full advantage of current tech.

Such is the case for earlier Mac Pros. As they currently sit, they only move data at SATA 2.0  speeds, roughly three gigabits per second. If you wish to put the drives in to a RAID array, you are limited to either a mirrored RAID 1, losing half your capacity, or a RAID 0, which is faster, but increases the risk of data loss. On top of that, those RAID levels are all software-based, which can reduce overall performance.

Fortunately, if you happen to have a 2006-2008 Mac Pro, you can improve the performance in those bays, with only one small thing to lookout for. Article Continues…

Newer Technology Announces MAXPower RAID mini-SAS 6Gb/s Controller Cards For Doubling Mac And PC Data Transfer Rates

Thursday, September 22nd, 2011 | Author: OWC NewsFeed

Newer Technology, Inc announced today its MAXPower RAID mini-SAS controller card line. Available in a choice of two external ports or one internal/one external port configurations, the MAXPower RAID mini-SAS cards provide full data transfer of four drives through a single cable connection for up to twice the data transfer speed offered by the SATA 2.0 (3Gb/s) data bus. Both versions of the MAXPower RAID mini-SAS controller card are available now form Other World Computing.

mini-SAS: More Lanes = Faster Speed

Just like a four-lane highway offers the fastest vehicle traffic flow, mini-SAS offers more “lanes” for data to travel at higher speeds. This interface offers the convenience of a one-cable connection but provides four separate channels so each drive can deliver Article Continues…

Where’s the Thunderbolt? It’s coming.

Thursday, August 4th, 2011 | Author: OWC Chris S.

Apple shipped its first Thunderbolt-equipped machines (MacBook Pros) in February. The next batch of machines (iMacs) hit in May. And in July, we got treated to minis and MacBook Airs with this port as well.

People were/are excited: Thunderbolt promises fast data speeds, daisy-chaining of displays and devices, and reduced desktop clutter overall.

However, as of this writing, there’s only one Thunderbolt storage device that seems to be available. The only “Thunderbolt” displays you can currently use are the 2011 iMacs in display mode (though you can still connect to mini DisplayPort displays just fine) and Apple’s own offerings. Heck, the first actual Thunderbolt cables themselves were only made available in late June.

So what’s the hold up?

This isn’t just a matter of slapping another port on an enclosure via an Oxford chipset and calling it a day. There are a lot of factors that play into designing a Thunderbolt device.

The main one is Thunderbolt itself. This is a new interface paradigm, the technical details of which only recently became available. So while we knew it was coming, there really wasn’t a whole lot that we could do in the development process until that point.

So where does that leave us now? Sure, we could rush a product out the door based on new technology that’s not widely adopted/deployed. But there’s a big difference between “getting it out” and “getting it right” when it comes to product development. “Good enough” isn’t the way we like to do things here at OWC.

We’d rather take our time and build a solution from the ground up, using the best proven technology. Sure, we may not have the first product out the gate, but if/when we release a Thunderbolt-enabled storage solution, you can be sure it’s going to be the same kind of high-quality product you’ve come to expect from OWC.

And when we do, you can be sure you’ll hear about it first right here on the OWC Blog.

 

2011 Mac mini works with OWC 6G SSDs

Friday, July 22nd, 2011 | Author: OWC Chris S.

After extensive testing, we’re glad to announce that both the OWC Mercury EXTREME Pro 6G line and our Mercury Electra 6G line of SSDs are fully compatible with the 6Gb/s SATA 3.0 ports on both the 2011 Mac mini and the 2011 Mac mini Server.

Both drive models work great, without the dropouts and other inconsistencies that we have seen in the 17” 2011 MacBook Pros.

Like its predecessor, the 2011 Mac mini Server has two drive bays, which can see the drives individually or in a software RAID 0 or 1. We tested a pair of Mercury EXTREME Pro 6G SSDs set up in a RAID 0 inside the mini Server and achieved read/write speeds over 1000MB/s!

The “regular” Mac mini only comes with a single drive installed. It appears, though, that a dual drive setup is certainly doable (though we can’t really comment on it until we look into it more, so please don’t even ask - just keep checking back; we’ll post it when we know for sure).

However, since the “regular” Mac mini comes as a single-drive unit, that’s how we tested it. It didn’t disappoint, either, getting speeds of over 500MB/s Read and over 420MB/s Write using one of the EXTREME Pro 6G’s.

You can see the results of both series tests below.

As you can see by these scores putting a 6Gb/s-capable SSD (or SSDs) in your 2011 Mac mini or Mac mini Server, really helps it achieve fullest the data transfer speeds possible.
