Hi,

I don't know.

They still will be faster than SATA 2 HDDs. However, when I migrated
from SATA 2 to SATA 3 I was surprised about the quick startup, it's
more or less power on = booted and I'm still amazed about the increased
virtualbox performance, my Windows 7 guest became faster than the
children's "offener Ganztag" Windows 7 installs on bare metal. Unlikely
an issue for you, but the known GTK app performance issues, such as the
visible black box when widgets are established, have nothing to do with
the disk drives.

I don't know, but as already mentioned by an earlier reply to the
former subject, I decided to buy OCZ SSDs, because they were the cheapest
that time and the AUR provide packages for OCZ tools, ocz-ssd-utility,
oczclout and ocztoolbox, see https://aur.archlinux.org/packages/?O=0&K=ocz .

My drives are neither supported by clout (the CLI tool to e.g. show smart
attributes), nor by ocztoolbox (a GUI). Fortunately ocz-ssd-utility (another
GUI) does the job, since smartctl is quite useless:

[rocketmouse@email-addr-hidden ~]$ sudo smartctl -A /dev/sda | grep Unknown
167 Unknown_Attribute 0x0022 100 100 000 Old_age Always - 0
168 Unknown_Attribute 0x0012 100 100 000 Old_age Always - 0
169 Unknown_Attribute 0x0003 100 100 010 Pre-fail Always - 0
173 Unknown_Attribute 0x0012 180 180 000 Old_age Always - 0

Actually the GUI explains the "Unknown_Attributes".

167 SSD Protect Mode
168 SATA PHY Error Count
169 Bad Block Count
173 Erase Count

Ralf
