Intel Takes SATA Performance Crown With X25-E SSD
theraindog writes "We've already seen Intel's first X25-M solid-state drive blow the doors off the competition, and now there's a new X25-E Extreme model that's even faster. This latest drive reads at 250MB/s, writes at 170MB/s, and offers ten times the lifespan of its predecessor, all while retaining Intel's wicked-fast storage controller and crafty Native Command Queuing support. The Extreme isn't cheap, of course, but The Tech Report's in-depth review of the drive suggests that if you consider its cost in terms of performance, the X25-E actually represents good value for demanding multi-user environments."
Try using a RAM disk.
Except those same drives don't exactly compare due to a poor implementation of the hardware or the write/cleaning algorithm in the JMicron controller many (all?) of those are using. The capacity and price are tempting, but the write latency especially during random accesses is beyond awful. Unless of course they were able to update the firmware on those chips to address the issue since this article was published: http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3403&p=7
It becomes a very fast cdrom - read only.
From the article: "The storage controller is an Intel design that's particularly crafty, supporting not only SMART monitoring, but also Native Command Queuing (NCQ). NCQ was originally designed to compensate for the rotational latency inherent to mechanical hard drives, but here it's being used in reverse, because Intel says its SSDs are so fast that they actually encounter latency in the host system. It takes a little time (time is of course relative when you're talking about an SSD whose access latency is measured in microseconds) between when a system completes a request and the next one is issued. NCQ is used to queue up to 32 requests to keep the X25-E busy during any downtime between requests."
