![]() ![]() The X41 uses the same, standard 44-pin IDE interface that every modern laptop IDE hard drive uses. This is the way I understand things when it comes to the X40/X41 hard drive main bay IDE interface and the drives used therein: Alternatively, the voltage converter from 5V variant with a soldering iron to remove."Ĭould anyone please explain it all nicely, so that it's clear even to those w/o eletrical engineering b/g? So the 5V version of the adapter must be selected for the models of x4x (t) series there is a 3.3V version of the adapter, because these models "from the first" work with a voltage of 3.3V to the IDE port. (possibly also the R5x and X3x Series so far untested). Accordingly, should a mSATAtoIDE adapter and the "downregulation" of the voltage from 5V to 3.3V guarantee for the Thinkpads T4x model. Modern SSDs with mSATA form factor using a voltage of 3.3V, conventional 2.5" IDE hard drives on the other hand 5V. " Important: Different adapters variants! Just found a bit more about it although the way I understand its Google translation is that both X4x and T4x are 5V: if an adapter with 5V 2.5" IDE connector is plugged into X40/41, which I suppose have 3.3V 1.8" IDE? So different voltages in adapter adverts imply IDE and so have nothing to do with voltage(s) in the mSATA connector in such adapters? Matching with msata ssd solid hard disk to replace 1.8" ide hard disk ,and connects to your Thinkpad X40 X41."ĭo I get it right that being electrically incompatible, those 3.3V 1.8" IDE connectors mate with 5V 2.5" ones too mechanically, meaning any adapter with the former one will die upon plugging into T4x laptops, which I suppose have 5V 2.5" IDE? And what about the other way round, e.g. This card can only connect with 1.8" 3.3v ide interface, if connects with the 2.5" ide interface ,the chip will be burning. For instance this one, probably with the best voltage explanation I've come across: ģ.3 Volt Mini PCI-e SSD (mSATA Module) Support. I've run into confusion around 5V vs 3.3V while going through hundreds of various mSATA-IDE adapter adverts. and not a 1.8" 'microSata'.īack to the main topic of this thread (adapters). Please make sure that the PM800 that you are watching is an 'mSata'. There may be other 'used' options in that list for your search. This post by Johan lists a number of msata SSDs which have worked in adapters. Plextor M5M 256GB msata SSD, Dell M6700 Sata-3 adapter in HDD-bay. R=21.316, W=37.502Īctually, I find the "130Mb/s" for "4k QD=1 W speed" almost hard to believe based on the following : Crucial M550 128GB msata SSD, T42 w/adapter. Toshiba THNSNF128GMCS 128GB msata SSD, T40 w/adapter. Plextor M5M 256GB msata SSD, T40 w/adapter. seen in one of the reviews cannot be achieved with UDMA7/SATA-I and are only reachable with SATA-II/III? As to several hundred MB/s sequential speeds, I doubt they would matter anyway because of the bottlenecks elsewhere in the platform. There's a big difference between Pata speeds and Sata-3 speeds.ĭo you mean that even 4k QD=1 R/W speeds ca. The speeds seen in reviews are normally at Sata-3 speeds. ![]()
