ssd for SATA I

I have a Vaio SR that seems to be using SATA I which transfers at 150mb/s. so is there a benefit to getting SSD that is overachieving at 200mb read/ write or just get something like the kingston V series?

btw, amazon sells it way cheaper at $220+

 

Definitely worth it - you could always sell it or put it in your new notebook that does support Sata2. Until then, you'll be enjoying the maximum speed your current system has to offer - I suggest Intel G2's for your main consideration.

The JMicron based drives are currently not worth it for any money at this point in time. Better to get a Hitachi 7K500 7200 RPM 500GB drive for $80 currently at newegg.com

 

It turns out that after all the testing, the data show that the SATA 1 bandwidth is not a factor at all in practical application.

The big speed numbers you see with SSDs are for sequential read/write speeds, so they don't mean much. Computers rarely read files sequentially for very long.

The only measure that really counts is the speed of reading and writing small blocks of data, the 4k speed. See Anandtech for the research on solid state disks.

 

T61Dumb,

Just want to add: 'not a factor at all in practical applications' with currently available SSD's.

 

so the kingston v series is a no go? it mainly has half the performance of good ssds with the same access time weight savings, power savings. and im sticking with this laptop for awhile.

 

especially if you're sticking with this laptop for awhile; stay away from the JMicron based V series Kingston's.

Which are the good Kingstons'? That's easy they are the ones with the following capacities because they are actually rebadged Intel's:

40GB
80GB or
160GB.

 

thanks, i think i will go for the 80gb one from intel... how do i know which is G1 and which is G2? all i see is them with x-25M

 

Look in the part number near the last four digits.

I'm pretty sure the SR is not SATA 1 but the HDD in it was.

My SZ supports SATA 2 speeds (how else do I get over 200MB/s sequential read) - it would be nonsensical if a newer laptop has SATA 1.

 

DetlevCM,

that's a good point! Just because the supplied HD is Sata1, doesn't mean that the Sata interface is.

+1

 

just like with any other data interface, things will generally jack DOWN to the lowest common speed. Firewire, USB, SATA, etc, etc.
