OCZ Vector 150 SSD Review: A New Flagship With 19 nm Flash

Meet The Vector 150, OCZ's New Flagship SSD

If you're a fan of conference calls, then you probably already know that OCZ isn't in the same rosy position it has been in years past. Fortunately, its enterprise-oriented offerings are really helping the company's bottom line. But the situation is darker on the desktop. It's still in the position of needing to source NAND from the fabs manufacturing it, which means it's paying more for the flash it uses and perhaps unable to ship as many units as it'd like.

But again, if you listen to earnings calls, you might already know all of this. What's important today is that OCZ is revisiting client storage with the Vector 150.

The original Vector employed 25 nm flash, and it proved to be a potent contender based on OCZ's Barefoot 3 platform. As time passes, however, it's not always possible to continue a drive family based on the same components. Like Intel with its SSD 530 and OCZ with the Vertex 3.20, transitioning from 25 nm NAND to newer 20 nm memory was important for economic reasons.

Obviously, Intel doesn't have a problem getting its hands on the latest in solid-state technology. That's one of the benefits of owning a fab. This isn't as easy of a problem for OCZ to address, though. Fortunately, the company has its hands on Toshiba's 19 nm Toggle-mode flash, which we already know to be fast.

How about OCZ's naming? Its Vertex 4 was superseded by the Vertex 450. The added 50 indicated a half-node step up on the evolutionary ladder. When we apply the same logic to the Vector (let's call the original Vector 1, for simplicity's sake), the Vector 150 is our result.

Ideally, we'll see this latest generation enjoy wider availability and a more attractive price, triggered by 19 nm NAND. Of course, because the drive launched last week, we can compare the original Vector to OCZ's Vector 150. At least right out of the gate, you'll find last generation's 128 GB model selling for less than its successor at the same capacity point. Naturally, then, you're going to see us compare old to new in an effort to assess the advantages baked into Vector 150.

Inside OCZ's Vector 150

Because this is a product refresh, it isn't surprising that OCZ is shipping its Vector 150 in the same capacities as the original. Or at least they're close, since the 150 employs some additional over-provisioning. There's the 240 GB model we're testing today, a 120 GB variant, and a 480 GB flavor. Here's the breakdown of their specifications:

Those are the basics. In addition, OCZ's retail box includes a 3.5" adapter sled for desktop installations, along with a product key for Acronis True Image to facilitate drive cloning (this is the same software we use in our lab to replicate a standardized benchmark image). Acronis offers oodles of other features too, including some solid backup options.

OCZ's metal chassis and thermal pad

Before we pop the top on this SSD, it's worth mentioning that OCZ's higher-end offerings sport the best chassis in the business. Some of its lower-end drives ship with simple plastic enclosures on a metal base, but the Vector 150 is just awesome. Its seven-millimeter-tall housing is both good-looking and heavy enough to inspire confidence. That's not great for super-light laptops, but it's what we enjoy for an enthusiast-oriented desktop. Crack the case open and we're granted access to the SSD's PCB.

The biggest change you see in going from the Vector to the Vector 150 is the latter's 19 nm ABL Toshiba Toggle-mode flash replacing 25 nm NAND. Our sample ships with eight dual-die packages per side, totaling 256 GB. Each die is manufactured at 64 Gb density.

Another tweak is extra over-provisioning. The 25 nm-equipped Vector was rated for 20 GB of host writes per day for five years. OCZ's Vector 150 is rated for no less than 50 GB per day. That's primarily due to a reduction in write amplification. It does throw off the price per gigabyte comparison, making Vector 150 more expensive per addressable gig. But the extra over-provisioning above and beyond ~7% of spare area is a reasonable tradeoff. Just be aware that the 50 GB/day specification isn't a fully random, full-span write. OCZ instead characterizes those 50 GB as "typical client conditions".

At the heart of OCZ's Vector 150 lies the company's own Indilinx Barefoot 3 controller. The IDX500M00-BC is the same silicon found in the original Vector. The Vertex 450 uses a lower-clocked variant, but also boasts features not available from the Vector, like AES-256 encryption. The Vector 150 enables that missing functionality, though it's unclear whether it comes from firmware or enhancements to the processor itself.

Finally, we find 512 MB of Micron DDR3-1600 CL11 DRAM. Each side of the PCB sports 256 MB, giving us 2 MB per gigabyte of on-board flash. The 120 and 480 GB variants will probably come with 128 MB and 1024 MB, respectively.

    It looks pretty good and it does perform pretty good.

    I just hope the quality increased. Only because at my last job we had used Vertex 3s for all of our work stations and they one by one started having random issues, from not being detected to wiping the partitions.

    I like OCZ because they help lower the price of SSDs but there has to be quality behind the price as well.

    Some of the numbers in the bottom diagram on page 4 seem to be off. Look at the Intel 520 180GB for example; the random write bar is longer than the random read bar, but the actual IOPS numbers are the other way around.

    My impression is that OCZ was hit hard by the Sandforce issues, partially as a result of being an early adopter. Their newer drives seem to be reliable.

    Awesome catch! The 520 seems to have the right bar length, but the label from the Intel 510. I'll sort that out, but that's a genuine not-my-fault problem. One of the very few. I can blame Excel 2013 with confidence, but kudos for the eagle eye.

    The random write bar is correct though; the SandForce-based 520, 525, and Intel 530 each pull down more random write IOps than read with incompressible data.

    I got two SSD vertex 4 128gb on my computer 3770k and on my girlfriend 3470 I never get an single error on this SSD. raid 0 or normal configs. run solid!

    Early on yes, but the 2nd gen SF drives really are pretty darn stable now. OCZ has had solid top tier releases since the Vertex 4. I own Vertex 4 and Vector, will probably get a 150. Hands down the worst thing they ever did was try budget/value offerings like the Petrol. I don't think there is any reason for fanboism, I own Samsung and OCZ drives and all work happily together.
