We’d expect all flash SSDs to stay below 1 W idle power. In fact, the Intel and Samsung drives switch into low power idle modes, initiated by the devices or the host system, and reduce idle power to 0.2 W or less. These are great results, especially for notebooks or mobile workstations.
Solidata, however, shocked us with inopportune idle power consumption, which is 20 times higher than the results of the Intel and Samsung drives. Even high-performance SLC-based flash SSDs by Mtron require less than a quarter of the Solidata drives’ idle power consumption. I guess there is still a lot of room for improvement here.
If you want maximum sequential throughput, the power consumption of most SSDs increases to anything between 0.8 W and 2 W, which is excellent—mechanical hard drives require at least 50% more power. Solidata again is way behind at 7 W, which clearly disqualifies the drive for notebook applications. It’s amazing to see Samsung’s power consumption at maximum throughput: 1.0 W is a new record.
Playing HD video off the SSDs means limiting the data stream to a lower bit rate. In this case, the Intel and Samsung SSDs are very efficient, at 0.2 to 0.3 W, while the other SSDs mostly need between 1 W and 2 W. In contrast, Solidata requires 5.2 W. In their defense, though, I want to point out that this is close to the idle power level of 4.9 W so this represents a power increase of approximately 0.3 W. Clearly, the base power requirement is the issue.
Most drives hit their peak power requirements if you request lots of random I/O operations. Solidata jumps to as much as 10.9 W in the case of the X2-128, while the new Samsung 256 GB SSD stays at 1.5 W and hence requires 25% less power than the Intel X25 SSDs. This promises to be an exciting shootout, as we now look at performance per watt.

Hot or Not? New Samsung and Solidata SSDs
Samsung’s new 256 GB flash SSD is a screamer, while Solidata created a questionable RAID-based SSD that runs incredibly hot. Check out one example of what a new SSD should be and another example of what not to buy in this increasingly competitive market.

Samsung, Ridata SSD Offerings Tested
Ridata's Solid State Drive offers great robustness while Samsung's doubles capacity to 64 GB. But which one should you buy?
Nice artice, but 1 small note, on page one.. isn't Samsung’s new PB22-J available a little bigger than 256 MB? Seems small..
Can we have the drop down list of pages back?
I really don't want to go through every single page to get to the results and conclusions.
jpdykes there is a table of contents at the very top.. but i to like the drop down menu
Price?! I can't seem to find it in the article...
Also note that on the graphs the Intel x25-M is labeled as 64GB, where on pg 8 it says it comes as 80 or 160.. Also did the x25-M have the new firmware?
Good point - I missed that!
i like the new table of contents
nice edit
The 256Gb Samsung is available for general sale in the UK; I bought one last week.
I just wish new Table of Contents (TOC), or drop down was on every page, after I get past page 1, you either have to go back to page 1 to jump ahead/around or page though
no OCZ Vertex?
Considering that the Samsung PB22-J is a MLC-based drive like Intel's X25-M, Samsung beats the crap out of Intel with write speeds.
Also, Register Hardware reviewed the same drive six weeks ago!

@ 1st poster. It think they meant GB
page 2 hard drive specs, 80-500gb??? shouldn't that be 2tb?? and price $100 for 320gb?? try $50 for 320gb or $80 for 500gb
We used to get 3 and 4 new articles a day.Now it's been reduced to one.
I would think with all new teck in the market place we can find more than just hard drives to talk about.
As I mentioned before there are a new host of monitors out there.One that do 120htz and the response times have gotten better.It would seem the 24 inch monitors have been catching up to the smaller 22 inch counter parts in terms of speed.
This is the would be article you won't get for a long time I am afraid.
What I also find odd is that there are more ads on Toms than before but they get rid of our avatars?I have to wonder why?
Thank You for making the "Table of contents" actually accessible!!!
Place the table of contents in every page, not just the first. And put it at the bottom of the page, so you can use it after you read the page. Currently you read the page and have to scroll up to use it.
This article avoids detailed discussion of the controllers used in the SSDs, does not emphasize the importance of small random write tests, and implies that OCZ does not have a product, when in reality the OCZ Vertex using the Indilinx controller has the second best performance to Intel at half the price. The JMicron controller is garbage. Read the vastly superior articles on AnandTech "The SSD Update" and "The SSD Anthology" for more information.
Perhaps this is an irrelevant question, and you'll understand why in a moment, but would owning an SSD with a throughput of over 200 mb/s help in situations where the amount of available ram is exceeded? IE - in games where instead of writing to RAM, the program would have to write to the HD as virtual ram. Oftentimes I would notice a stuttering when a new area in a game was streamed from the HD when I didn't have available ram, would this effect be eliminated? (The reason I felt it was somewhat irrelevant would be because those of us who can afford to buy a $400-600 SSD drive can probably afford a few more gigs of ram - or would have the ram in the first place.)
Drop down list again please, forcing me to see all of your ads by removing drop downs, or having a dozen image pages instead of text only forces me to add more things to adblock.
