Thinkpad X300 With SSD Performance Evaluation 133

Posted by Zonk from the solid-gone-man dept.
Ninjakicks writes "Hard drives are typically one of the more significant performance bottlenecks in any system today. An evaluation of Lenovo's new ultra portable Thinkpad X300 notebook shows a fast solid state hard drive can substantially improve the performance of a system. This is especially true of a low-end, low power processor and integrated graphics, in addition to reducing overall power consumption. Despite its 1.2GHz CPU the Thinkpad X300 is actually able to outperform some desktop replacement notebooks equipped with dual 7200RPM hard drives in RAID 0 in productivity benchmarks, and in data transfers. Interesting results, especially considering the X300's ultra portable form factor."

      If they really wanted to show the performance improvement of SSD vs HDD, the least they could have done was run the tests using the X300 with its SSD drive replaced with a 5400 and 7200 RPM HDD even though neither is an available option.
      • Are 5400/7200 RPM HDDs available in that form factor? I think it's using the 1.7" form factor, definitely not the 2.5" standard laptop form factor.

Mine boots reasonably fast (about the same as my other front end with an old 120GB drive), but it took about 20 hours to install Fedora Core 8 and run a software update. Every once in a while it freezes on live TV playback, and I think it is some sort of delay writing to the flash drive. My other front end has no such problems. The one with the CF has better specs than the one with the hard drive - much faster processor, more memory, better video card.

          This is true to an extent, but there are trade-offs that can't be made when using the computer. You may be able to turn off sections of a chip, but not nearly with the level of detail that you can by not adding transistors at the beginning. Trying to convert a fast, out-of-order CPU with many pipeline stages into a slower, in-order CPU with fewer pipeline stages at runtime would be effectively impossible. Additionally, the way that the chips are manufactured affects their speed: for example, fast transistors generally have higher leakage currents, so you have to compromise between high clock speeds and low static power.

      Well first of all moving a file (on the same device) is irrelevant, I assume you mean copying it. Yes SSDs have slower write speeds and that is an issue, 3-4 times slower is an exaggeration though (and the rotational speed of the drive has very little relevance to its write speed unless the drive is nearly full and heavily fragmented - which of course it isn't in any common benchmarks). Swap space is the only thing this may become an issue, but then again you're springing the extra $1k for an SSD in your laptop you've probably also paid the extra $50 for 2GB of memory, making swapping a rare event.

      But for write few, read many data warehousing tasks, SSDs are an enourmous benefit. Think about Google, where the filesystem is optimized for reading due to large files being created and read from all the time for search results (yet the files aren't constantly rewritten). Or think about Netflix needing a huge video library to serve movies over the web. The movie content isn't changing, so it would make sense to have huge libraries of SSDs that save power by not spinning, get written to once with a block of movies at a time, and get read from all the time from customer devices.

      SSDs have their place now. And they're only going to get more popular as the price comes down.

      My understanding is that the technology being used in "SSD-Hard Drives" is quite a bit different than the tech being used in the average cheap thumb drive such as my 4GB one.

      By the same token, the tech being used in the iPod Touch is quite a bit different, which is how it can offer 32GB of flash storage for ~CDN$500 while a 64GB SSD upgrade for a MacBook Air is CDN$1,400.

          Writes cannot usually be performed asynchronously though - because they need to conform to the api presented. e.g. close() or sync() guarantee the data is written to non-volatile storage, whatever that may be. Being able to cache bits of the write in memory may help but at the end of the day it's all gotta be stored once close() returns, so it makes no real difference to many applications apart from being able to better store the data on disk. e.g. a compile writes files which are read by another programme later.

          Er.. close() does not guarantee that any data has been written at all. sync() guarantees that the kernel has flushed its in memory buffer, but it does not guarantee that the disk controller has flushed the write cache. Writes does not block unless your program is stupid enough to wait for it to complete. For the compiler example, gcc writes .o-files from source which ends up in cache (=fast). Then when it is time to link, it reads them all to build the executable or library. Reads are synchronous so now g

      No, it isn't. Partly because of increases in the number of write cycles they can support, but mostly because of size increases and wear leveling.

      Consider a 64GB device with a write cycle limit of 100,000. Assuming constant rewriting of all of the data, you'd have to write 6.4 petabytes of data to wear it out. Assuming you could deliver sustained writes at 22 MB/s (150x), it would take 6,400,000,000 / 22 = 290,909,090 seconds, which is over nine years of continuous, max data rate writing.

      • I guess it really depends on how much free space you have on the device. If you have an 64 GB device (just for example), and 32 GB is filled with apps, those will never be overwritten, and will always stay in the same place. Now you only have 32 other GB in which your other data that is constantly changing to be written. Look at it this way. If you have 10 MB free, and want to write 1 MB, then there's only 10 choices for each byte it writes of where to put it. That could wear out your drive quite quickl

        • I guess it really depends on how much free space you have on the device.

          Assuming the naive implementation of wear leveling I described, yes. I did a little research this morning and modern CF cards are much better than what I described. They do relocate static data whenever there are blocks with significantly higher wear than average. They also have one million write cycles, not 100,000.

          Take a look at the Wikipedia article on wear leveling and at the links it provides.
