Intel's X25-V & Kingston's 30GB SSDNow V Series: Battle of the $125 SSDs

Sequential Read/Write Speed
Using the 6-22-2008 build of Iometer I ran a 3 minute long 2MB sequential test over the entire span of the drive. The results reported are in average MB/s over the entire test length:
Read performance is identical between the two value drives. The older SSDNow V Series based on the X25-M is actually a bit slower, perhaps due to its older firmware.
At 41.9MB/s, the X25-V has half the write speed of the 80GB X25-M G2. Kingston's 30GB drive is faster at 52.5MB/s, but we're still slower than the peak sequential transfer rate of a mechanical hard drive or the 80GB X25s.

The SSD Toolbox won't work on RAID volumes unfortunately.Take care,
Anand

Thanks Anand for clarifying the raid and SSD toolbox issues. I can see now that adding a second 40 GB drive will not be a good idea and I should save for a larger capacity.I am very interested in knowing when Intel gets trim working for raid! Good to know I can count on Anandtech for the latest SSD news. Thanks again, Scott

The difference between 30gb and 40gb is HUGE,,, I would need 50 to swap my bloated win7inighthawki - Friday, March 19, 2010 - link
I have a 30GB partition for Win7 and still have 8GB left, and that's after some pretty careless space management. I don't understand how yours can be so bloated. You're not counting things like program files, are you? You're aware that the users and program files folders aren't part of your windows installation, right?gerstena - Friday, March 19, 2010 - link
"I have a 30GB partition for Win7 and still have 8GB left, and that's after some pretty careless space management."Unfortunately things like volume shadow services and the source files of windows updates quickly eat up the space. A lot of users won't know about these things.
The only thing I have found drives under 60 GB useful for are speeding up database operations and development.

I have 8 GB for OpenSuSE 11.2 and still have 3 GB free.I dunno about Windows bloat - yours or the other guy's!

Dear AnandYour nice review of Kingston indeed encouraged me to purchase Kingston 64GB SSD for my win7 system, but your TRIM comment just kept my purchase impulse at bay. Would you mind clarifying the TRIM situation in the future? If nothing wrong with TRIM implementation on Kingston SSD, I'll buy bigger brother, 64GB SSD, for my system immediately!
Thanks
