    Phoronix: Intel X25-E Extreme SSD Benchmarks On Linux

    In early January we had delivered Linux Solid-State Drive Benchmarks of an OCZ Core Series V2 SSD, which was a low-cost low-capacity single-cell drive. The increased performance and decreased power consumption compared to a 5400RPM Serial ATA 2.0 hard drive was nice for a netbook, but how are the higher-end solid-state drives performing? In this article, we have a high-performance Intel X25-E Extreme SSD on a System76 notebook running Ubuntu Linux.

    Too expensive for normal people who need big storage capacity. I wonder in how many years SSDs will drop to the price of today's HDs and totally replace them. Probably too many :P

      It didn't occur to you that the encoding benchmarks might be CPU-limited, as opposed to disk limited?

      More to the point, you made no mention of the common issues surrounding SLC Flash SSDs: re-write speed. The performance of single-level cell flash, when re-writing, is hideous.

        Uhhm... I'm pretty sure there's no way you were able to read from the drive with ~370 MB/s when Intel themselves advertises the read speed with 250 MB/s (that's almost the half! ). (refering to the IOzone 4GB Read Performance).
        You are probably just writing to cache (at least partialy). I think you should look into possibilities to disable the cache if you want to accurately measure the SSD-performance.

          Bad SSD benchmark

          Too many non-ssd related tests and thereby uninteresting graphs! What about running tests designed to expose some of the problems with today's ssd? I'm talking about OCZ's sucky IOPS and things like that..

            This Intel SSD's supposedly do not suffer from the random writes problem most other SSD's seem to have; it would have been interesting to see some tests with this SSD vs HDD vs the other SSD that was tested some time ago to confirm/disprove that this SSD doesn't suffer from latency troubles.

              Any chance of seeing boot times in the next test? Please

                The cache on SSDs is minimal and irrelevant. A typical cache size is something like 64KB. When it comes to SSDs, data is typically written directly to the drive itself. It's entirely possible to reach the numbers quoted under ideal circumstances.

                My main concern with the article is that the benchmarks are a bunch of compression and encryption tasks, followed by some synthetic tests. Hardly representative of "real world" stuff. Also, there was no mention of the proper things that need to be done to get maximum performance out of the drive, like aligning partitions and setting proper block sizes, among other things. Sure, the Intel drives don't suffer from the same "hesitation" as most of the lower-cost drives on the market, but that doesn't mean it wouldn't improve performance to set the drive up properly.

                Another interesting thing would've been a discussion of filesystems that are geared directly to SSDs, but that was never mentioned either.

                  Boot time

                  I have a request for another benchmark and that is boot times. Please consider this benchmark in future tests.

                    I agree. My SSD more than halved my desktop system's boot times, it was incredible. Since SSDs are most often used on notebooks, boot times are definitely relevant.
