Its 80 g weight makes the 256 GB 2.5” PB22-J 20% lighter than conventional hard drives, and it can operate in a wider temperature range of 0-70°C. In contrast, mechanical drives are typically specified for 5-60°C or even less.
Unlike most other flash SSDs, Samsung’s data sheet specifies that the device supports Native Command Queuing (NCQ) with a queue depth of up to 32 commands. This is not the case for most flash SSDs, with the exception of a few of the latest products based on Samsung or Promise controllers. Samsung also specifically says that the drive supports device and host initiated power management, which means that the flash SSD can be put into a low power idle mode by the operating system, or it can do this on its own.
Like Intel’s X25 family, Samsung built the new device on multi-channel flash memory, which is imperative not only to support fast read performance, but to ensure that it can actually write at a decent speed. In fact, Samsung’s new PB22-J is the fastest writing flash SSD based on MLC flash memory. The device utilizes a controller that was developed by Samsung, and it incorporates a 1 Gbit SDRAM chip as a drive cache memory. This is necessary to support NCQ, and to make sure that the eight memory channels can be utilized at maximum efficiency.

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.
