Thank you all very much for your feedback – and especially a big
thanks to berlibaer
for taking the time and effort to become a user on this forum, simply to reply to a question I asked via the eBay messaging system – because berlibaer is one of the buyers of the IDE 44 Pin to 1.8" Micro SATA Adapter
which we amongst other things are discussing here. Your helpfullness is much appreciated, berlibaer
! @ everybody else
who are following this thread: I have been collecting a bit more information lately about this adapter; info which I believe other ThinkPad’ers could be interested in and which I therefore wish to share. By ”collecting” I more precisely mean that I have been fortunate to meet some both were knowledgable and very friendly people via eBay; users who have all purchased this specific IDE 44 Pin to 1.8" Micro SATA Adapter
and buyers who I therefore contacted hoping that they could perhaps shed a bit more light on how good or bad this adapter could be expected to function on e.g. a ThinkPad T42. Also, I have a received information - from the seller of these adapters - about the compatibility of these adapters (information which I couldn’t quite figure out from the eBay listing). Below are the comments that I have received so far.
In my message to the eBay-seller of these adapters, "microsatacables", my mail entitled: ”Question about IDE 44 Pin to 1.8" Micro SATA Adapter
: 3.3 V or 5 V at 1.8" adapter side?
", I wrote:
<introduction, not of relevance here, so snipped>
I have one question which I kindly ask for your help to clarify - before putting these adapters to work: I have an IBM ThinkPad T42 laptop which uses an ordinary 2.5" PATA/IDE harddrive. I wish to replace this (relatively old and slow!) mechanical HDD with a fast Intel solid-state drive (SSD). However, Intel SSD's are only available as SATA and therefore I wish to use your "IDE 44 Pin to 1.8" Micro SATA Adapter" in my T42 along with the Intel 1.8" SSD model X18-M (the datasheet for which can be found here
As you will see from the datasheet, the Intel X18-M requires 3.3 V (and will die immediately if being subject to 5 V!). My 2.5" PATA laptop supplies 5 V at the 2.5" PATA connector. In your listing for this adapter you write the following: "Supports both 3.3 V and 5 V Micro SATA 1.8 Inch Drives
My question is this: I am uncertain what you exactly mean by: "Supports both 3.3V and 5V Micro SATA 1.8 Inch Drives"?? How will the adapter know if the 1.8" SATA drive require 3.3 V or 5 V? Is there a switch or something on the adapter to set to select the voltage?
In reply to this question...
... I immediately received this extensive answer from the expert-seller, Doug, who wrote:
The adapters will operate both 5V and 3.3V drives they are built this way. The microSATA drives themselves have a built-in disconnect. This means the that the 3.3 V drives have a disconnect on the 5 V line and the 3.3 V drives have a disconnect on the 5 V line. This is a self-protect device built into the drives.

Then to the comments received from the eBay-buyers of this adapter, who have very friendly replied me, and who have shared their experience. First:
... coming from our friend in South Australia, eBay'er "ghan66", who wrote:
I used the adapter to replace the flash memory in a HP Thin Client with a 1.8 HDD, not a SSD. I can boot from the HDD and it is OK speed wise. I am using Windows 7 but have not tried Windows XP. Hope this helps. Cheers
... and then:
... I received a reply from eBay'er "paoloberno83" in Italy, who wrote:
I'm sorry but i can't help you...
My idea was exactly to use a 1,8" ssd in place of the 2,5" hdd but my notebook broke two days after i received the adapter so my plans changed and i bought another notebook...
Remember that you can't send trim commands through the adapter so you should choose a ssd with garbage collction like the ones with sandforce 1200 (i.e. ocz vertex 2) or, better, with the new toshiba controller (the same used in macbook air) like the kingston ssdnow v+180 i was planning to buy...

I've not had an opporttunity to convert the machine the adapter was purchased for so, I can not provide you with any real world feedback. I'll have to look at the forum discussion to see what I can add. But I can say, that you will not be able to acheive full SSD speed compared to a new machine with a real SATA adapter, because of the max performance of the IDE hardware is just now where close. But I would still expect a nice speed bump.

The adapter worked fine for me on my tablet PC running Windows 7. Booting is flawless. Some benchmarks:

(As reported by AS SSD Benchmark on Windows 7.)
I cannot comment on the adapter's performance with Windows XP. Downsides to the adapter: 1. The HDD activity light on my laptop never lights up -- but it used to work fine with a 2.5" PATA drive. 2. While I saw a modest performance increase by upgrading from an older SSD to a modern one, it was not as large as I hoped.
I hope this helps. You may share this report with your bulletin board if you like.

Using the SATA - PATA adapter in the main drive caddy of my Inspiron 5150 I had some inconsistent results with Intel Gen2 SSD's. Some times the drives were not recognized and boot issues. With both XP and W7.
My two GEN1 X18M's have worked very well.
The throughput of the SATA - PATA adapter (uses jmicron chip) is slower than other chips I am familiar with. My 5150 has peak speed of UDMA5 and X18M 80GB G1 writes around 20-30Mbps, reads 70-80Mbps (it's the super low seek time that makes SSD snappy). That's still faster reads than my 5400rpm Samsung and WD platter IDE drives @ about 45-50Mbps reads/writes or a WD SATA 7200rpm platter through the newmodeus caddy @ 60/70Mbps read/write.
With a newmodeus optical bay caddy that uses a different chip (marvel maybe), throughputs are much better: X18MG1 60Mbps writes, 90Mbps reads. G2's are a little faster 70/95 write/read. Even through the newmodeus caddy I had some boot problems with G2 drives and have settled on using G1.
Caveat: The crappy Graphics card on the Dell Inspiron 5150, a Nvidia GeForce Go5200 is a >>huge<< weakness and probably contributes to boot issues/difficulties with W7. XP works much better with this machine's configuration. Your mileage will vary.
I do have a successful dual boot XP/W7 installed on the 5150. X18M G1 drive with XP Home through SATA-PATA board in main drive caddy; X18M G1 with Windows 7 Home through newmodeus optical bay caddy. Had to use a modded Nvidia vista graphics driver to get W7 working with consistency.
FWIW, I also have a desktop, UDMA6, X18M G1, running dual XP Home, through a SATA pci card (Rosewill RC209 (?)/ SiliconeImage 3512 (?)chip) controller that gets throughput around 70/115Mbps WRITE/READ. I will be adding a G2 drive with Windows 7. Preliminary tests showed X25 G2 160GB with throughput around 10-15% faster than G1 in the desktop.
That all being said, I just bought a new Dell XPS 15 L501X. Will prob'ly sell the 5150.
So, that's all for now - quite a bit of information to absorb, I'd say!
I have ordered a couple of these adapters (although they haven't arrived here in Denmark, yet), so when I get an Intel X18-M I'll simply start playing with this SATA-SSD in my good, ol' 15" FlexView/IPS PATA-T42p!
Until then: Please report back if any of you out there who has actually tried
to use this IDE-to-SATA adapter with a SSD in a PATA-ThinkPad (a T42 or something else), and have some actual real-life experience. I am in particular "worried about" whether it may perhaps be a better idea to take the (big, and basically unwanted) jump and switch from my stable, completely satisfactory XP to Windows 7, since I would guess that an Intel X18-M would be able to take advantage of TRIM under Windows 7 (in despite of the above comment by paoloberno83
, who claim that TRIM commands cannot be sent through this adapter??). It is my "understanding" or "anticipation" or "assumption" that the Intel SSD Toolbox
in the X18-M and is not dependant of, say, this adapter? I however admit that I don't know what is the truth on this matter... TRIM via this adapter? The adapter datasheet is very
All for now. Will update if there's anything to add. Feel very
