SSD – english

The original German post can be found here.

I just got myself a SSD for my Yoga 2 11. But wait there is no Sata-Connector ?

Yes there is. But only models with a ST500LT032 got a Sata-Connector. Which means I only need to get the right connection-cable – and if you know where you can order it pretty cheap.

According to the Hardwar Maintenance Manual the correct P/N Number is: 90204934. Replacement parts can be bought directly at Medion for about 8 Euros.

I got myself a TOSHIBA THNSNJ256GCST (it was on sale over Christmas). Height: 7mm. It fits into the Yoga 2 11 but it is a very tight fit.

 

The big Disappointment:

There is almost no speed increment.

~$ sudo hdparm -tT /dev/sda

/dev/sda:
Timing cached reads: 3258 MB in 1.99 seconds = 1633.77 MB/sec
Timing buffered disk reads: 776 MB in 3.00 seconds = 258.48 MB/sec

 

~$ sudo hdparm -tT –direct /dev/sda

/dev/sda:
Timing O_DIRECT cached reads: 458 MB in 2.01 seconds = 228.39 MB/sec
Timing O_DIRECT disk reads: 696 MB in 3.00 seconds = 231.75 MB/sec

 

~$ dd if=/dev/zero of=tempfile bs=1M count=1024 conv=fdatasync,notrunc
1024+0 Datensätze ein
1024+0 Datensätze aus
1073741824 Bytes (1,1 GB) kopiert, 5,09668 s, 211 MB/s

 

Nevertheless I think I spent my money well

First a SSD is immune to movement, since it got no turning disc.

And second the whole laptop does not make any noise anymore. No fan-noise, not CD-drive, no harddrive.
