H


ow big a deal is Intel’s entry into
the solid-state-drive game? The
announcement of the company’s
new X-25M SSD, and a faster version for
enthusiasts, all but overshadowed details of
the company’s next-generation CPU at its
fall developer conference.
Aft er testing Intel’s entry-level SSD, we
can understand why. The X-25M off ers the
fastest read speeds we’ve ever seen from a
single SSD or hard drive.
How fast? The 10,000rpm Western
Digital Velociraptor (reviewed September
2008) off ered sustained transfer speeds of
98MB/s. The $1,500 MemoRight MR25.2-
32/64S GT from our SSD roundup (Novem-
ber 2008) turned in read speeds of 112MB/s.
The Intel X-25M hits 206MB/s read speeds.
Not all is roses though. The X-25M SSD
is based on the more-aff ordable multilevel

chip (MLC) technology. The Achilles’ heel
of MLC drives is subpar write performance.
For example, the RiData and Super Talent
MLC-based drives in our seven-drive SSD
roundup averaged write speeds of about
23MB/s. The X25-M is almost three times
faster than the other MLCs, but it can’t touch
the write speed of drives that are based on
single-level chip (SLC) memory. The slowest
SLC drives hover in the 80MB/s range, with
the faster drives pushing 100MB/s.
The X-25M SSD took a hit in our Pre-
miere Pro benchmark, in which we write an
uncompressed Microsoft AVI to the drive.
The Velociraptor hard drive continues to
be the best performer in our Premiere Pro
benchmark, with the Memoright SSD com-
ing in a close second.
That’s probably the only thing that
dampens our enthusiasm for this drive.

The X-25M’s read speeds are simply to
die for—you’d have to run lesser SSDs or
hard drives in RAID 0 to even come close.
Just think about what you’d get from two
X-25Ms in RAID 0.
This is just one of many SSDs you can
expect from Intel. The company plans to
release a 160GB SSD next year. For enthu-
siasts, Intel will soon introduce the X-25E,
with 250MB/s reads and 170MB/s writes.
Because it will use SLC technology, though,
it’ll be far pricier.
As for the X-25M, we’re unimpressed
by its write performance, but since its read
speeds are twice as fast as those of the other
SSDs we’ve tested, and it costs about a third
of what the fastest SLC drive on the market
runs, we have no choice but to pronounce it
Kick Ass worthy. –G O R D O N M A H U N G
