Final Words
From a technological standpoint, the Vector 180 is the most interesting Barefoot 3 based SSD that we have seen in a while. With partial power loss protection (PFM+) and a new 960GB capacity, it's able to bring something new to the now two and a half year old Barefoot 3 platform and most importantly it offers some long desired differentiation to OCZ's client SSD lineup.
I'm not sure what to think about PFM+ because drive bricking due to sudden power losses is fortunately quite rare, and if it was a critical issue then all client-grade SSDs should incorporate some level of physical power loss protection -- not just the high-end drives. In my mind it mainly offers an extra layer of protection and peace of mind, but OCZ would have had to go with full power loss protection in order to add real value to the end-user (although in that case OCZ would have jeopardized its own enterprise SSD sales). I think PFM+ is a nice addition and at least brings something slightly new to the market, but I wouldn't consider it to be a deal breaker because any user that really needs power loss protection will still have to look for enterprise drives.
One point I want to bring up is the performance consistency at different capacities. It really looks like the Barefoot 3 was designed ideally for 240/256GB as going above that will result in some issues with performance consistency. It's normal that companies have an optimal capacity in mind when designing a controller because optimizing for higher capacities will always require more processing power due to the additional metadata handling, which in turn results in higher cost. Back in 2012 when the Barefoot 3 was launched the price per GB was nearly double of what it is today, so it made sense to focus on 120GB and 240GB capacities since 480GB and higher were a small niche due to the high price. Fortunately the IO consistency issues didn't translate to our Storage Benches, but still there are better optimized high capacity SSDs available that don't have any consistency issues.
It's also too bad that the Barefoot 3 lacks support for slumber power states because its active power consumption is simply the best we have tested so far (excluding the 960GB model) and the difference in favor of the Vector 180 is in fact quite substantial. The Vector 180 would be a killer for mobile use if it had proper slumber power management, but since the idle power consumption is ~700mW at its best whereas other drives are able to achieve 20mW, I just can't recommend the Vector 180 or any Barefoot 3 SSD for a laptop/tablet. OCZ's next generation controller, the JetExpress, will support DevSleep and slumber power states and I certainly hope it will share Barefoot 3's excellent active power consumption behavior.

Since the Vector 180 is OCZ's flagship, it's also priced accordingly. The MSRPs are very close to what the 850 Pro and Extreme Pro currently retail for and it's clear that OCZ is considering the two as direct competitors to the Vector 180. The problem, however, is that the 850 Pro is better as it's faster, more durable and has longer warranty and better hardware encryption support (Opal & eDrive), so the only area where the Vector 180 can compete is the price, which isn't happening with the MSRPs (of course, actual street pricing may end up being different).
All in all, despite PFM+ and a 960GB capacity, the Vector 180 is ultimately the same Barefoot 3 that we have seen numerous times already, and it's a natural transition to more cost effective Toshiba's A19nm NAND. The performance is good and roughly on par with the Extreme Pro, but it's not high enough for the Vector 180 to truly have an advantage over other high-end drives. To be frank, there's no arguing about the fact that the 850 Pro is a clear leader when it comes to SATA 6Gbps performance. On the other hand, given that client PCIe SSDs are only a quarter or two away, I think anyone who is considering a high-end SSD should hold off their purchase for now. There is no point in upgrading from a SATA SSD to another SATA SSD at this point because the performance benefit will be marginal compared to what PCIe will bring to the table, so you will simply get far more value for your money if you wait a bit. That's also where OCZ's focus is right now and the JetExpress definitely looks promising.

Looks like an overpriced product that doesn't stack up against competition in the same price range. Given OCZ's extensive track record of failures and attempts to use their user base as unpaid beta testers I can understand their desire to include a feature to give more peace of mind, but in reality it's just not that useful and certainly insufficient to overcome years of accumulated ill will.serndipity - Thursday, March 26, 2015 - link
The specifications say it all.On a $, performance, reliability, endurance, warranty basis, the OCZ 180 falls significantly short of even the consumer grade competition (e.g. Crucial or Samsung).
Unfortunately, the OCZ story when from deceiving investors, to customers, ending in bankruptcy.
Sadly, the same management etc., remains in place
Be smart and avoid OCZ

Hi LB-ID, thank you for your feedback. We have shipped countless Barefoot 3 based drives across multiple series products and never once had to rev silicon. We have made updates to firmware to continually improve our products. The addition of the PFM+ feature was a decision to support customers that are really on the edge of enthusiast and workstation. This is a required feature for many enterprise drives and we felt there was a value to including this feature into our Vector 180 Series. We agree that not every customer necessarily needs this feature, and for those customers across the client spectrum we have other BF3 based drives that do not include the additional circuitry, but for those customers that really would like that extra layer of protection we were able to integrate this feature without a price premium over our previous Vector 150 Series. We have already received a very positive response from some users but will continue to offer a range of drives to meet the needs of different user applications.voicequal - Friday, March 27, 2015 - link
Wow, great review and a ton of new tests and data. The bathtub curve on the mixed sequential read/write performance will be very interesting to compare to forthcoming NVMe drives. I was surprised by how much the IOPS were reduced by commingling of sequential reads/writes. Seems to be room for improvement in this area.Ethos Evoss - Saturday, March 28, 2015 - link
The worst company of SSD's some OCZ or OWC or PVC .. jeez trash.. it's been sold to toshiba anyway ..ocztosh - Monday, March 30, 2015 - link
Hello Ethos Evoss. We are sorry that you feel this way and/or if you had a negative experience in the past. We are indeed now part of Toshiba and OCZ Storage Solutions is a very different organization as a subsidiary of Toshiba. Toshiba has provided the ability to vastly enhance resources for product development as well as given us complete access to their premium NAND. We certainly will continue to strive to meet the high expectations of you, our valued customers. Thank you again for your input.daerron - Tuesday, May 26, 2015 - link
Nice in depth analysis Anandtech! Read the article as I'm receiving a new Vector 180 240GB drive this week as my original Vector bricked itself earlier this month after around 2 years of service. I have to say that I'm really impressed with OCZ's customer service as I couriered the drive last week and will be receiving a brand new and latest SSD in return this week. Fortunately I had my data backed up as it really just died without any warning. Based on the analysis I was also thinking this would be a killer laptop drive, till I saw the lack of slumber support which is a bit of a disappointment and opportunity missed. Still the PFM+ and low power usage is also most welcome in my workstation PC. We have regular power cuts in my country so its great to have that extra peace of mind.bogdan_kr - Thursday, December 17, 2015 - link
Hello guys. I would like to ask how exactly this Storage Bench - Light is designed. The description says it is designed to be an accurate illustration of basic usage with Total IO Operations 832,339, Total GB Read 17.97 and Total GB Written 23.25.With its 23 GB of writes it should account for roughly two or three days of average usage (i.e. 7-11GB per day).
How long (typically) does it take to finish this bench?
Is it designed to last for few hours (which would account for a typical daily use) or is it designed to finish as fast as possible, in few minutes perhaps?

I am aware that most likely it is a rhetorical question but can anyone from AnandTech answer it, please? I just wanted to be sure about that benchmark.
