With each page being 4kB in size this results in a block size of 512kB. So, with either 0.5MB or the more widely used 1MB offset (Win7 etc.) your partitions will be aligned to the block size!</P> Tue, 29 Sep 2009 09:14:57 GMT idata 2009-09-29T09:14:57Z https://community.solidigm.com/t5/archive/partition-alignment/m-p/743#M605 <P>I have a Intel X25-M SSDSA2MH080G2C1 2.5" 80GB. I believe partition alignment to the nand block size is important for performance on SSD's. What is the nand block size on this drive? How can I check that the partition is aligned properly?</P><P></P><P>Thanks </P> Tue, 29 Sep 2009 00:42:23 GMT https://community.solidigm.com/t5/archive/partition-alignment/m-p/743#M605 idata 2009-09-29T00:42:23Z https://community.solidigm.com/t5/archive/partition-alignment/m-p/744#M606 <P>Hello!</P><P></P><P>The NAND erase blocks on Intel MLC drives are 128 pages wide.

My partiton was misaligned as I had copied the partition to the SSDs with Acronis from a Dell PC which had a restore/utility partition. I fixed the alignment and got a good increase in performance as you can see.</P><P></P><P>Before</P><P></P><P>After</P><P></P><P> </P> Fri, 02 Oct 2009 01:40:58 GMT https://community.solidigm.com/t5/archive/partition-alignment/m-p/745#M607 idata 2009-10-02T01:40:58Z
