61系列SATA2限速解决思路

looklulu

这位朋友的机器没有启动AHCI模式吧？

另外和大家说一下目前的状况，从X61T机器来看，其内存对应限速位的数据是1h,而联想F31对应位的数据是2h，从ICH8 datasheet来看，X61T是被限速了，而F31是全速sata2的。
不过现在问题是在内存中对上述数据位无法修改（会自动跳回），不知是否有办法解决？
另外从BIOS文件中寻找对应的数据居然没有找到，也许是我对BIOS不熟，也许有其它原因。
如果有对BIOS熟悉的，请支援一下。

没有比阉割更痛苦的事情，更痛苦的是我不光有台T61，还有X61,谁去告LENOVO，我赞助500块。

加大悬赏，，谁去告LENOVO T61设计缺陷赞助１０００人民币！！！

我的t60用的INTEL X25-M 最高达到110M每秒在不限速的台式机能达到240M每秒
积求解决限速问题啊

lenovo真是暴飧天物啊，t61这么好的配置，硬是要阉割sata2，不知怎么想的。

支持技术贴。x61t能破解sata2的限制就换块SSD。

买不起SSD 的飘过另外我还是比较喜欢机械硬盘便宜啊量足

大家来凑点基金给楼主吧,我觉得可以和TB上卖X25的谈一下赞助绝对拉动出货量

顶顶楼主吧

虽然速度对我来说意义不大

--------------------------------------------------------------
All,

I've investigated this issues at length through engineering and have received the following explaination of SATA data rates available on the Santa Rosa ('61) and current Montevina based systems (T400/T500, W500, W700, etc)...
"For Santa Rosa-based systems, the Intel ICH8 supports a SATA bus speed of up to 3.0 Gb/s. Lenovo made a design decision to prioritize maintaining compatibility with Ultrabay disk drives, which are connected via a SATA-to-PATA conversion chip which could not handle a 3.0 Gb/s SATA bus speed reliably. Therefore the system was standardized to 1.5 Gb/s.
In testing rotating media drives, our measurements show data throughput difference between 1.5 Gb/s and 3.0 Gb/s bus speed is less than 5% since the drive mechanics are the limiting throughput factor, rather than the SATA bus itself.
For those customers who choose to purchase an after-market SSD drive capable of SATA bus speeds up to 3.0 Gb/s, the system will interface with them at 1.5 Gb/s. Lenovo's official position is that the Santa Rosa systems are working as designed.
The Montevina based systems which began shipping last year have direct SATA interfaces for both drive bays and are enabled at a system level for SATA bus speeds of 3.0 Gb/s performance. Current Lenovo drives have firmware set to 1.5 Gb/s data rates.
Exchanging these drives for after-market drives which support SATA bus of 3.0 Gb/s should provide for the higher data rate at the overall system level. Again, it should be noted that our performance measurements show less than 5% performance improvement between 1.5 Gb/s and 3.0 Gb/s SATA bus speeds for rotating drives, since the drive mechanics are the limiting throughput factor, rather than the SATA bus itself.
After-market SSDs which support SATA bus speed of 3.0 Gb/s will operate at that bus speed. Depending on the data transfer test method used, your actual data throughput from a 3.0 Gb/s SATA bus speed should be 220-250 MB/s and about 90-120MB/s throughput when running on SATA bus of 1.5 Gb/s. This is due to the bus signaling used for the SATA bus, as well as overhead for error checking."

偶明白联想的意思，联想意思说本身ICH8是支持SATA2的，但是因为考虑到Ultrabay slim，就加了个转换芯片以让Ultrabay slim的东西也能使用，但是那个sata-to-pata的转换芯片不支持sata2。

这样就意味着如果改了可能就无法使用ultrabay slim的东西了

这个一定要顶一下的～～
