Hi, I've a VPCZ12M9E with 2 SSD in raid0, I'm also using encrypted lvm on top. I don't remember what these SSD are.
$ sudo hdparm -tT /dev/mapper/panic-root /dev/mapper/panic-root: Timing cached reads: 6048 MB in 2.00 seconds = 3024.36 MB/sec Timing buffered disk reads: 894 MB in 3.01 seconds = 297.39 MB/sec $ dd if=/dev/zero of=/tmp/output.img bs=16k count=256k 262144+0 records in 262144+0 records out 4294967296 bytes (4,3 GB) copied, 20,0337 s, 214 MB/s Note that I'm not using any optimization for SSD (such as mounting / with noatime and using more appropriate kernel scheduler) Didier On Sun, 22 May 2011 22:20:44 +0200, [email protected] wrote: > Hi people. > > I ran a little test to know about the performances of the Ricoh SSD drive > (of the VAIO Z13) on a Raido0 array. > > Mine has two SSD of 64GB. > > A little benchmark with hdparm > > for i in 1 2 3; do hdparm -tT /dev/hda; done > > and one other with dd for write test : > > dd if=/dev/zero of=/tmp/output.img bs=16k count=256k > > tell us the I/O are performing at approx. 245MB/s read and 340 MB/s write > > Thisis a very minimal test that should be extented further by varrying > file and block size. > > It would be very intersting to know the performances of other > configurations (raid0 array of 4 drives and without raid) > > > _______________________________________________ > Mailing list: https://launchpad.net/~sony-vaio-z-series > Post to : [email protected] > Unsubscribe : https://launchpad.net/~sony-vaio-z-series > More help : https://help.launchpad.net/ListHelp -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ Mailing list: https://launchpad.net/~sony-vaio-z-series Post to : [email protected] Unsubscribe : https://launchpad.net/~sony-vaio-z-series More help : https://help.launchpad.net/ListHelp
