Power Consumption: Incompressible Sequential (Windows 7/Mac OS X)
by
Andrew Ku
128 KB Sequential Read
Sequential performance is largely unaffected by the type of data you're reading. But does power consumption change? We know that data compressed by SandForce's DuraWrite feature suite must be decompressed, bringing up the potential for higher power use. That turns out to not be the case, though. Reading compressible data yields lower power consumption in most cases.
128 KB Sequential Write
Similarly, power use is lower when it comes to writing compressible information, contrary to what you might have expected.

Hmmm, maybe I missed a good excuse, but I'd like to see the Octane in these tests.
I love Intel SSD. 128GB for about $210 isn't bad. It is just hard to not chose something like a Corsair GT 120GB that cost $150 with rebate over this. I would always put a Intel SSD in a computer for novice since it is reliable.
Nice Review!
Nice article
Just need more SSD's to compare, I'd like to see similar tests done with 120GB...180GB...256GB and several more brands. Further, as I mentioned before in the other article please list the exact model numbers and OEM specs including their 4KB IOPS; otherwise folks don't understand the results and if relying on this a purchasing will have in many cases a 4 in 5 chance of selecting the wrong SSD.

costly but i think reliability comes at a price. These ssds are best for enterprises . If the price will be little lower then the common user can afford these and get a good reliable ssd.
"Measuring boot time is one of the best illustrations of how an SSD benefits your computing experience." Be that as it may I find it almost irrelevant seeing as I hardly ever boot my computer, perhaps 2-3 times a month if that. Getting out of standby on my HDD is a matter of seconds.
These prices are lower than I thought. $20-$40 extra (depending on the comparison) for peace-of-mind is not outrageous.

We didn't have the Octane on hand in the 256 GB capacity, but we'll be sure to make that side by side comparison down the road.

Excellent point. Price is always a fickle thing.
Nice Review!
Thanks Les.

We'll keep that mind for future reviews. However, we already list model and firmware on the test page.

And with an SSD, your computer comes out of standby faster than your monitors do. Not kidding.
Anyone else disappointed Intel isn't producing their own high end chipset? Been waiting to upgrade my X25-M for a while now (Intel 320 isn't a big upgrade) but might just go with Samsung.
Good to see Intel throw its hat into the ring for the prosumer market. We should be able to expect performance and out-of-the-box functionality (as opposed to theoretical endurance) for the amount of money these devices cost. As the article repeatedly infers, this has not always been the case to date (although the last year has seen some major kinks worked out). Competition at the mid to upper end of the market will lead to higher expectations.
Yes, I'm with you on that one. I've had an Intel 320 128Gb SSD for quite some time now and have nothing but the greatest things to say about my particular experience with it. I purposely held off from buying the Marvell controller 510 in hopes that the next refresh would have a new Intel made 6Gb controller. One thing I am curious about, does the new 520 still have the Intel Toolbox software with it? I have gotten alot of use out of it with my current drive and would really hate to not have it on a new one.

You can use the Toolbox software with the SSD 520. It will however not work with other SF drives.

Andrew, could you please comment on the encryption capabilities of the new drive. Does it support AES encryption like the Intel 320? Is there an option for pre-boot? Thanks in advance!
Andrew,
Your SSD investigations/reviews/history lessons are Tier 1.
But I always get curious when Intel starts on and on about how it has the best NAND around. It's not that I even doubt them when they say this, but AFAIK Intel/Micron/IMFT are made and binned in the same place.
IMFT is supposed to be 49% Intel and 51% Micron-owned. Now both companies' own drives are stocked with what I presume is the best available NAND at that price point, but how did Intel get the reputation of having better NAND? (and if I'm honest, there is at least some evidence that it does). Micron doesn't run around talking up their NAND as much as they should, and this makes me think that the details of the IMFT arrangement are probably pretty strange. In a blind taste test, they taste pretty similar.
But not all Micron NAND is created equal, nor is Intel's (for example, does Kingston really get Intel's top shelf shtuff?). The IMFT NAND used in so many drives today runs the gamut from fantastic down to mediocre, only one step above Hynix's too-dirty-for-television flash. I'm probably the one person on this planet that wants to know more about Intel, Micron, and their bastard love child, IMFT.
So, does this SandForce's SF-2281 controller has the bug as well?
Or it is already fixed?
Or they have replaced it with a new version?

As far as Anand can tell... no.

Intel's SF2281 implementation seems to be stable, and BSOD free.
... my OCZ Vertex 3 is still strong...
I have a crucial 128 my next will be Samsung
Thank you for the OS X benchmarks! There are real differences between Windows 7 and OS X and having these benchmarks helps Mac users make better upgrade decisions.
