The speed decrease measure when changing IDE to SATA
1.Speed decrease measure when changing a hard disk of a PC to SATA-> IDE/ssd/hdd/xp
-My impressions which correspond actually-
1.Trigger
Built-in HDD was bought for future's backup because the outside bill HDD
which has not passed for 1 year since it was bought the other day broke,
and data went off.
By a manufacturer different from a manufacturer of broken outside bill
HDD, well, SATA 2T made in wax SEAGATE.

A PC corresponded to only IDE, so this change adapter was used to use HDD of SATA.

A change adapter is moving to itself favorably, that SATA was changed to IDE, it itself beckoned speed decrease....
They seem to say whether it's after it already falls in price in only about one week's having passed since this hard disk was bought on July 18, 2012, that this article is being written or-, but I'd like to pull myself together, write it and go (warai).
2.Speed comparison
The rate of 40GHDD before an exchange.
It seems to have been included in a PC of sale just as it is in around 2003, so it's HDD before nearly 10 years.

It becomes later than the front.
A benchmark became slow, but I thought the actual speed became early, so they were left alone, but I'm interested as expected....
3.Measure
I have checked it by a net and have just tried variously.

Like, it was 2-triple quickness.
When I did IDE change of SSD from SATA and connected, it was same as a measure to the phenomenon slow in speed in the same way.
When changing from SATA to IDE, the cause was to recognize transfer mode as udma2 though it was udma6 primarily.
(warai) even named as "udam2 disease"
When making them recognize the place recognized as udma2 as udma6 by force, original speed has gone out.
The method isn't difficult very, a method, until it's found, it took time.
It's securely with this.
Read and Write, it's necessary to take a measure separately.
(1) Read measure
Software as [hdparm] is used.
This seems to be made software and be relics in the past already by early PC industry of a change in 1999, but it's surprise to be useful for a bad measure of the latest HDD.
(2) Write measure
Software as [WPCRSET] is used.
4.Side effect
New hard disk became early with this, Write of a hard disk of 60G of Maxtor connected to a slave of IDE from before became slow.
When I said more, before exchanging a system drive for new hard disk, a hard disk of 60G of Maxtor connected to a slave of IDE had gone out of Read 45MB/s Write 44MB/s, at present.

Maxtor
The situation that I say so.
If it's a side effect using software as [WPCRSET] to improve Write of a SATA hard disk at the top, that Write goes out of 16MB/s seems.
Because Write has also gone out of 32MB/s if WPCRSET is released.
Slave's drive is used for a backup now, so because master's drive gave up, and became early, no, if it's used, but there is a person who knows the cause and the measure by which slave's Write became slow.When you can tell, I'm thankful.
Only a master drive of IDE is being exchanged and slave's drive isn't being twiddled this time, slave's benchmark.
Read 45MB/s Write 44MB/s
-> Read 31MB/s Write 30MB/s (before WPCRSET use)
10MB/s fell, if there is a person who knows this cause and measure.When you can tell, I'm thankful.
