I just installed a new Intel 330 60 GB SSD into my HP Mini 2140 laptop.
But it's not going as fast as expected and my hdparm results aren't looking very good compared to SSD benchmarks at:
My results and info are below.
hdparm results:
justin@justin-HP-2140:~$ sudo hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 1130 MB in 2.00 seconds = 564.50 MB/sec
Timing buffered disk reads: 372 MB in 3.01 seconds = 123.53 MB/sec

In the HP Mini 2140 BIOS there are 2 options that from some other issues may have an impact:
- SATA : Enable/Disable
- Dual Core/CPU support: Enable/Disable
Both of these are enabled my default. If i disable SATA then the hdparm results show it is twice as slow.
Has anyone experienced slow SSD? Or seen an issue with the HD config? Or know how to fix this to get speeds that a new generation SSD should be capable of?
Note that this is with a fresh install on 12.04 LTS.
Note: by slow i mean 20 second boot to desktop (no login), 5 seconds to start terminal - was hoping that with ssd starting apps would be 1 sec
update:
- thanks for all the answers - have applied TRIM and noop - helps a bit
- but think the main problem as identified by john is the limitation of hp mini :(
