And so proclaims Networkworld. Check out there findings- here's a snippet:
In our tests, the X25, released this week, is faster twice as the next fastest SSD we've tested and beats the fastest hard disk drive in reads and ties it in writes. The 80GB version, which we tested, is priced at US$595 for quantities up to 1,000.
Recently, one of the fastest drive I've reviewed was Western Digital's Velociraptor hard drive. Its 10,000rpm spindle speed and 16MB buffer had it returning a 250.2MB/sec burst speed and 105.6MB/sec average read through HDTach. In my file transfer tests, 4,661 files of various types totaling 8.05GB, writing the data to the Velociraptor took a mere 4.4 minutes and reading the data from it and writing it to another drive needed only 4.04 minutes.
To be fair, the Velociraptor is too large for most laptops and netbooks (it's a 2.5-inch drive wrapped in Western Digital's 3.5-inch "Ice Pack" heatsink form factor). The next fastest I looked at (in the same article) was another Western Digital drive, the Scorpio Black, with a burst speed and average read result of 238.8MB/sec and 63.8MB/sec, respectively.
Intel's X25-M has them both beat. The SSD turned in 256.7MB/sec and 230.2MB/sec burst and transfer rates, respectively. Actual file transfers ran just 4.4 minutes and 3.7 minutes to and from the SSD.
How is it's speed in comparison to another SSD- No problem: Ridata's 64GB Ultra-S Plus is almost half as fast as Intel's X25-M when tested under HDTach while its real-world file transfer times are noticeably slower. The X25-M is a fast SSD.
The X25-M booted under loaded conditions (every piece of software and all drivers needed to run the system) in just 1.32 minutes. When I stripped some of the excess out of the startup, boot time dropped to 1.18 minutes. In contrast, Ridata's 64GB Ultra-S Plus needed 1.47 minutes to boot with all drives and software included and 1.23 minutes when pared down.
The surprise here is the Scorpio Black hard disk drive, which went through a loaded boot in 1.28 minutes -- faster than either SSD -- although when booting into a stripped environment it stalled a bit at 1.26 minutes. The mechanicals of the drive imposed more of a burden on the boot process than the depth of the boot environment itself, perhaps bearing out the advantages of an SSD with no moving parts.
