There are/were a few minor issues with the microSATA solution :
- 1.8” microSATA SSDs are becoming increasingly hard to find
- not all 1.8” SSD brands and models work perfectly with the Jmicron JM20330 chip on the IDE-to-microSATA adapter
- the HDD activity LED light stopped working
I recently purchased an mSATA SSD for a newer laptop which has an mSATA bay (sata-II).
I decided to also purchase “ST663FD9 mSATA to IDE 44pin converter adapter with 2.5 inch case” so that I could test an mSATA SSD in my T40, and hopefully find an SSD solution that works easily for ANY normal IDE laptop.

Forum member ‘Acheron’ had problems with this adapter fitting properly (http://www.thinkpads.com/forum/viewtopi ... 2&t=110642), but other reviews/feedback for this adapter were positive so I inspected it carefully before assuming that it would fit perfectly.
Length and width look good.

Pin alignment is the problem.



The solution was to remove the two mounting screws from the 44-pin edge of the assembly, place that edge of the board under the tabs instead of on top of the tabs, and leave the two mounting screws at the other end to attach the board to the ‘case’.

The pins are now aligned properly and everything fits together perfectly.

This adapter/case is professionally packaged ... very impressive. There are a number of screws since the adapter can also handle half-size mSATA SSDs ... read the instructions and study the pictures so that you know which screws are used with which option. Actually, based on the overall quality of this adapter, I am quite surprised that the 44-pins were not aligned properly for a recessed caddy installation.
The advantages of the mSATA SSD and ST663FD9 adapter solution :
- much easier to find current technology mSATA SSDs
- the Jmicron chip in the adapter is the newer JMH330 which fixes some (all?) of the issues of the older JM20330 chip
- the HDD activity LED light works
- an mSATA SSD will be easier to re-deploy in a newer PC than a 1.8” microSATA SSD
- a very nice SSD solution for ANY of the older normal IDE laptops
I tested the mSATA SSD / ST663FD9 adapter in my T40 with both Win7 and XP (both operating systems were ‘aligned’ properly). I started ~20 processes so that memory was filled and paging was occurring ..... no problems. I also used ‘TRIMcheck’ to verify that Win7 ‘trim’ was working thru the JMH330 chip on the ST663FD9 adapter (‘trim’ works properly thru the JM20330 chip also). TRIMcheck also showed that ‘trim’ was not working on XP ... as expected.

My opinion :
- I wouldn’t buy an old mSATA SSD ...... no warranty; most models were OEM and firmware updates are not available from some manufacturers for OEM models; some of those old models had firmware issues for which you won’t be able to get fixes.
- new technology mSATA SSDs are usually faster (won’t be noticed in an IDE or sata-I install but I expect almost any SSD will be re-deployed when the IDE laptop gets retired); and have better firmware, error recovery, and garbage collection mechanisms than the mSATA SSDs of 2-3 years ago.
Some additional slightly off-topic info :
Just for fun, I also bought “AD963FD9 SATA-III to mSATA 6Gb/s SSD converter adapter with 2.5 case”. My goal was to compare the mSATA SSD in an mSATA bay (sata-II) vs. the sata-III adapter in a HDD bay. Even though the user chose the additonal storage space of an HDD in that bay and decided to keep the mSATA SSD in the mSATA bay at sata-II speeds, I now know how easily an mSATA SSD can be used in an IDE adapter, an mSATA bay, or in a sata HDD bay with an “AD963FD9” adapter (no problems with ‘pin alignment’ with this adapter). I learned a great deal and had lots of fun at the same time.
Here’s the CDM results of sata-II vs. sata-III (Dell Precision M6700 with i7-3720QM) :
