AnandTech Storage Bench
To avoid any potential optimizations for industry standard benchmarks and to provide another example of real world performance we've assembled our own storage benchmarks that we've creatively named the AnandTech Storage Bench.
The first in our benchmark suite is a light/typical usage case. The Windows 7 system is loaded with Firefox, Office 2007 and Adobe Reader among other applications. With Firefox we browse web pages like Facebook, AnandTech, Digg and other sites. Outlook is also running and we use it to check emails, create and send a message with a PDF attachment. Adobe Reader is used to view some PDFs. Excel 2007 is used to create a spreadsheet, graphs and save the document. The same goes for Word 2007. We open and step through a presentation in PowerPoint 2007 received as an email attachment before saving it to the desktop. Finally we watch a bit of a Firefly episode in Windows Media Player 11.
There’s some level of multitasking going on here but it’s not unreasonable by any means. Generally the application tasks proceed linearly, with the exception of things like web browsing which may happen in between one of the other tasks.
The recording is played back on all of our drives here today. Remember that we’re isolating disk performance, all we’re doing is playing back every single disk access that happened in that ~5 minute period of usage. The light workload is composed of 37,501 reads and 20,268 writes. Over 30% of the IOs are 4KB, 11% are 16KB, 22% are 32KB and approximately 13% are 64KB in size. Less than 30% of the operations are absolutely sequential in nature. Average queue depth is 6.09 IOs.
The performance results are reported in average I/O Operations per Second (IOPS):
The higher capacity SandForce drives rule the roost here, but the C300, X25-M G2 and V+100 are not too far behind. Despite its age, Intel's X25-M G2 performs very well in our light usage test. The V+100 isn't far behind thanks to its 8.5% improvement over the original V+.
As far as small capacity drives go, the Corsair Force F40 and other similarly sized SandForce drives are the clear winners here. Crucial's 64GB RealSSD C300 is quicker than the X25-V, but no match for the 40GB SF drive.
If there’s a light usage case there’s bound to be a heavy one. In this test we have Microsoft Security Essentials running in the background with real time virus scanning enabled. We also perform a quick scan in the middle of the test. Firefox, Outlook, Excel, Word and Powerpoint are all used the same as they were in the light test. We add Photoshop CS4 to the mix, opening a bunch of 12MP images, editing them, then saving them as highly compressed JPGs for web publishing. Windows 7’s picture viewer is used to view a bunch of pictures on the hard drive. We use 7-zip to create and extract .7z archives. Downloading is also prominently featured in our heavy test; we download large files from the Internet during portions of the benchmark, as well as use uTorrent to grab a couple of torrents. Some of the applications in use are installed during the benchmark, Windows updates are also installed. Towards the end of the test we launch World of Warcraft, play for a few minutes, then delete the folder. This test also takes into account all of the disk accesses that happen while the OS is booting.
The benchmark is 22 minutes long and it consists of 128,895 read operations and 72,411 write operations. Roughly 44% of all IOs were sequential. Approximately 30% of all accesses were 4KB in size, 12% were 16KB in size, 14% were 32KB and 20% were 64KB. Average queue depth was 3.59.
This is another one of those SYSMark-like situations. The old Toshiba controller did just awesome in our heavy multitasking workload and the new update does even better. At 1135 IOPS, the V+100 is 55% faster than the Indilinx based Corsair Nova. Thanks to the incompressible nature of much of the data we're moving around in this benchmark the SandForce drives don't do so well. Although not pictured here, the 256GB C300 would be #2 - still outperformed by the V+100.
The gaming workload is made up of 75,206 read operations and only 4,592 write operations. Only 20% of the accesses are 4KB in size, nearly 40% are 64KB and 20% are 32KB. A whopping 69% of the IOs are sequential, meaning this is predominantly a sequential read benchmark. The average queue depth is 7.76 IOs.
The perplexing nature of the V+100 continues here. While it boasts great sequential read numbers, the smaller and somewhat random accesses drop the V+100 behind the SandForce and Crucial SSDs.

The 2xnm lifetimes will be shorter. The flash lifetime is a function of feature size, so as processes shrink lifetime will as well. At the same time, it's only likely to be a concern if you're doing very IO intensive activities. My 128GB Indilinx drive is at 96% after a year in my main desktop. At this rate I'll be nowhere near the maximum write limit when the flash dies of old age in another 4-9 years even if I keep it as my main drive the whole time which is doubtful.If scaling is linear with feature area, as the 50% drop in life-cycles from 50 to 34 nm implies, 22nm 2 level flash will last about 2500 write cycles. This still will probably be long enough not to matter. 14nm flash and beyond might not be unless they switch to SLC for consumer SSDs, and only use MLC for memory cards and thumb drives. With 10x the allowed number of write cycles SLC flash should remain good for several additional process shrinks.
OTOH that might be a moot point because the power levels needed to write flash doesn't drop with each process, and unless something changes flash is expected to hit a will in the teens because the wires on the chip won't be able to carry the load without melting.

Anand, couldn't you just continue running your random write test 24/7 until it falls dead, or is this not feasible?Maybe it's not feasible with the Kingston drive because the random write performance is too slow? Which could bring up speculation that it's intentionally handicapped so this type of test is avoided?

Hello Anand,Really interesting article as usual. I had no idea that there was such a gulf between various Sandforce controllers. There was one line however that perplexed me, "The V+ 100‘s sequential read speed is excellent, just a hair above the top drives from Intel and Crucial. There’s not much room for improvement here unless you go to a 6Gbps interface."
Why didn't you use a Sata 6 controller? I think that most of us buying boards today will be looking at Sata 6 since so many today's current SSDs clearly outstrip Sata 3, to say nothing of the upcoming 500MB/s and better drives coming down the pipeline. I'm sure you have a good reason, and I know there has been some weird controller issues with AMD I believe, but I'm very curious! Thank you.

Just saw this on Gizmodohttp://slickdeals.net/forums/showthread.php?t=2365...
Puts it at around $1.60/GB and if you skip past the synthetic benchmarks and look at AT Storage Bench, its a pretty formidable drive. Makes me a little sad I spent more than this on my 160 X25M G2 a while back.

Brilliant...just needs controller info added. I think I'll do some searching later tonight if I have time.Is total capacity listed in GB (10^9) or GiB(2^30)? What about usable capacity? I wish people paid more attention to this, especially in area such as this were flash storage (typically in GiB) is being used for a drive (typically in GB).

Anand,Do you think a short description of which controller each drive uses could be added to the table on page 2? It seems to me that it would be much more instructive to sort the drives based on this, rather than the often rebadged brand.

How about this info when comparing SSD's? >1. Is it truly Plug and Play on any OS?
2. Does it have Alignment Agnostic Controllers?
3. Does it handle incompressible Data really well under XP?
Since the majority of computers still run XP, this information is the most valuable to the most people

There's a lot of stats for the drives, however I'm not any closer in choosing a drive.I have 3 systems:
1. Windows 7. This system is mostly lots of opened web browsers hogging memory, email, maybe a Word document, video encoding, and reference software (i.e. encyclopedia). I assume the browser is caching to the drive, same with the virtual memory and other background apps. I don't turn the machine off, so boot time is not important. For video encoding, I'd like to keep the data on a HDD since it is a lot of storage that SDD's are not affordable at storing, and it is most likely CPU bound.
2. Media Center. Want a SDD for the main drive (OS and apps), but will use a larger/slower drive for the media storage. Need something low heat. This is what I really want a SDD for.
3. Linux. Mostly emailing and web browsing. All the apps I use are cloud apps.
Obviously the fastest drive would be the one I want if money is no object. But I want to know how much faster my experience is going to be for how much more money? My goal is a snappy system and less time waiting around. I want to know what I'd sacrifice by getting a "value" drive versus the higher quality.
Also, MTBF is important. I hate losing data! Hope the drives have SMART or some other methods of warnings.
Thanks,
Jake

If all you want to do is boot up quickly and load your apps really fast, then a sandforce drive is perfect for youIf you want to manipulate data already on the drive or copy & paste to the same drive, then you are much better off with a 7200RPM desktop drive as far as I can tell
Anyone wanting to spend their time doing actual work instead of constantly tweaking their SSD to get synthetic benchmarks that have little bearing on real world results should avoid sandforce based drives like the vertex 2
