发帖数: 895 | 3 SSD vs. SATA RAID: A performance benchmark
Wednesday, 30 July 2008 16:00 Linux.com .

Without going into details, SSDs may use single-level cell (SLC) or multi-
level cell storage, with SLC drives typically offering better performance.
SSDs offer different read and write speeds, form factors, and capacity. I
looked at several models from Mtron. The performance of the 3.5-inch and 2.5

第二感觉是象块砖头，不要想拉风了。
第三感觉是设计极其细致。不该有的adware绝对没有，预装的utility都有用。比如连
pc-card, dvd-rw,BT,802.11a,sd slot,modem等等peripheral都可以设成不通电状态减
少耗电，特别是dvd-rw，可以设为一分钟不使用即断电！并且bios还记录总power on的
小时数。
第四感觉是有些配置落后时代，比如没有摄像头和mic,比如还有modem接口，比如用pc
card而不是express card,比如３个usb2接口在同一边。然而有些也有好处。express
card实在无用，而pc card可以有很便宜的adapter转接cf接口，用来接cf gps。
第五感觉是扩展性可以，不但有空余插槽接内存条，而且可以很方便的换硬盘，还有一个
mpcie接口可以未来接mpcie的gps或者3G/4G network。
当然也有没明白的地方，比如只有风扇出风口，没找到进风口。
另外，Made in Japan。很惋惜不是中国造的。
总而言之，如果it耐用，并且panason... 阅读全帖 |

错，只是它的PCI-e 6 pin好像有问题，插上GTX 460运行会随机重启，后来插上GTX
960后直接提示显卡没有电源，我们才发现是电源问题，开始一直以为是主板不好。但
是用Peripheral转接成8 pin后又很稳定。遗憾的是风扇声音有点大，然后return了。
现在想重新买一个550W电源，不想超过$50，最好线是可插拔的，大家有什么推荐的吗
？谢谢！ |

买大电流电源是没用的，因为那个电源接口后面有1A保险丝，而且micro usb接口电阻
还大。唯一可行的办法是从后方peripheral usb端口直接back power，这还是model 1
B+ (rev.2)能这么做，rev 1后方usb也有保险丝。即使这样，许多powered hub单个端

GiB address space into 64 GiB of physical memory

Memory remapping feature of a chipset/bios allows for the segment of system

the amazing thing is that it inverts the model of computing, and makes

with the dock, you can connect a bluetooth keyboard/mouse to the phone,
