Final Words

The ARC 100 provides what I expected it to do, which is its strength and weakness. The Barefoot 3 platform does provide excellent performance consistency and it has proven to be reliable over the last two years, but the performance in lighter workloads is only mediocre. I am glad that OCZ pursues consistency, but the truth is that average client workloads are more about peak performance as IOs tend to happen in bursts. Think about application installing and launching for instance – they stress the drive a lot but only for a short period of time and afterwards the drive will mostly be idling until another similar request comes in. It is true that an average user will most likely not notice the difference between two modern SSDs, but I still would have liked to see the ARC 100 being more optimized for lighter client workloads.

Another shortcoming of the ARC 100 is its lack of support for lower power states and TCG Opal. With most of today's PCs being laptops, OCZ is missing the needs of a huge market. I am guessing that there are some limitations in the Barefoot 3 silicon itself that prohibit OCZ from implementing proper low power state support – or at least that is what I hope because otherwise there is no good explanation as to why the Barefoot 3 continues to use so much power at idle. OCZ's next generation controller will support both DevSleep and Opal encryption, but in the meantime I can only recommend Barefoot 3 based SSDs for desktops.

NewEgg Price Comparison (8/25/2014)
  120/128GB 240/256GB 480/512GB
OCZ ARC 100 $75 $120 $240
OCZ Vector 150 $85 $140 $280
OCZ Vertex 460 $90 $140 $245
Samsung SSD 850 Pro $130 $200 $400
Samsung SSD 840 EVO $90 $165 $250
SanDisk Extreme Pro - $200 $380
SanDisk Extreme II $70 $140 $295
Crucial MX100 $80 $115 $220
Plextor M6S $80 $135 $280
Intel SSD 730 - $190 $340
Intel SSD 530 $90 $140 $250

Pricing appears to be competitive, although beating the MX100 is very tough. At capacities of 120GB and 240GB the ARC 100 is effectively the same price as the MX100, but I would like to see the 480GB drop in price to be more competitive. The mainstream market is all about price, so the ARC 100 cannot be $20 more expensive than the MX100 if OCZ wants to compete. Then again, 480GB/512GB SSDs aren't the normal target for mainstream users, so it may not matter too much.

I have to say that the MX100 is still my recommendation for most people because the feature set and value are just amazing, but the ARC 100 is a compelling alternative for desktop users. The better performance consistency makes the ARC 100 more suitable for heavier workloads, so for a user with a heavy-ish IO workload and a tight budget the ARC 100 is a great option.

    I'd rather have the cheaper/faster SanDisk Extreme II and its 10-year warranty.
  • Lonyo - Tuesday, August 26, 2014 - link

    10 year warranty doesn't mean much. In 5 years, if it dies you would probably just replace it with something far faster and cheaper. The warranty doesn't get you your data back, it just gets you a replacement drive.
    After 3 years you might like a replacement drive, but much more than that and it becomes pretty meaningless to get a replacement slow/old drive considering how quickly SSDs have advanced. A 10 year warranty is pretty meaningless for this type of product, which is probably why Sandisk are happy to offer it. It gives false peace of mind and they know most people wouldn't take them up on it.

    -- but much more than that and it becomes pretty meaningless to get a replacement slow/old drive considering how quickly SSDs have advanced

    We got the Great Recession because Bankster asserted that home prices, which had been exponentially rising, would do so forever. We're near, if not at, the asymptotic limit of node, esp. for NAND. Controller logic & error correction can do only so much.

    If the industry can invent a smaller, non-destructive written, piece of memory (which responds to current semi-conductor logic) then may be. But, were I to be betting, I'd bet that consumer SSD will be only marginally better in 3 years.

    That is what 3D NAND is for.
  • xenol - Tuesday, August 26, 2014 - link

    I'd argue raw bandwidth is really that important considering that RAM disks which is comfortably over 10 times faster than an SSD in terms of bandwidth for sequential and smaller reads still don't offer a huge performance improvement over an SSD that an SSD provides over an HDD (and even then, it's not linear). "Loading" at this point is initialization, and that depends entirely on software.

    I suppose it'd be nice if we had universal memory, but SSDs are not a good candidate for that.
  • TheWrongChristian - Tuesday, August 26, 2014 - link

    I tell you what, I'd take that bet. With SATA being replaced as the primary interface and 3D NAND, I can easily see peak performance doubling in the next 3 years, and significant improvements in steady state performance.
  • FunBunny2 - Tuesday, August 26, 2014 - link

    And what, exactly, will the normal SSD consumer (not an uber-gamer) do with that performance? Would s/he even notice? Will 3D NAND lower the price/byte to spinning rust? I wouldn't bet on that, either. My bet: in 3 years consumer SSD will still be performing "good enough" for Joe Sixpack at about the same price as "good enough" does today. What may be different: PC makers, if there are any left, will ship with an SSD rather than a HDD be default, and those with the need for mass storage will buy one with both.

    Performance is not the point - space is. You are correct that SSDs are already so fast that even a doubling ot tripling of perfomance will not make much of a difference.
    However, they are still too small. 256 Gb just doesn't cut it.
    ... I am not exactly sure where I am going with this ;-)

    Typical usage patterns change with the technology available.
    Imagine when VR becomes common place. You'd want things to load almost instantaneously because once the computer experience becomes truly interactive, fast response times are so much more important.

    I LIKE YOU, AND THE WAY YOU THINK. I must add however, that storage and access is not a bottleneck for 3d environments at the moment. If you had such immense immersive environments that our current storage read times were being the bottleneck, I think 780 ti's would be worth 100$ comparitively.
