I usually never see this (T2x and T3x) sub-forum, but by coincidence I just stumbled across this thread, and I would like to make a contribution which I am certain will be of interest for those who might consider upgrading their e.g. T22 from having an old, slow mechanical (PATA) harddrive to having a
FAST SSD, as I understand our new member (and welcome!)
techningeer is asking about/potentially considering:
In the threads
1.8" SATA to 2.5" IDE converter? and
T42 SSD Conversion Success (1.8" SATA drive + bridge board) the use of a 1.8"-SATA-to-2.5"-PATA bridge is discussed; it will allow a 1.8" SATA SSD to be mounted in an older ThinkPad, which are designed for having a 2.5" PATA drive. As seen from those two threads, focus there is on T4x ThinkPad's, but the same adapter can
also (!) be used in e.g. a T22... I know this from actual experience by forum.thinkpads.com member
GACrabill. Gary and I have for some time been testing one 2.5" PATA SSD (a 60 GB OWC as discussed in the thread
2.5" PATA OWC Mercury Legacy Pro SSD: Performance in T42?) and different 1.8" SATA SSD's in different ThinkPad's (a T22, a T40 and a T42p), with both Windows XP and with Windows 7. The T40 and T42/p results will be posted shortly in the two above-mentioned threads.
In the thread
T43 Installed Transcend SSD observations **PICTURE LINKS*** the performance of another (cheaper) 2.5" PATA SSD is discussed; I guess that this SSD will also work well in a T2x.
In his T22, Gary tested the speed of his (old!) 60 GB, 5400 rpm mechanical HDD and the speed of a Kingston SSDNow V+180 128 GB SSD (it is a microSATA II 3 GB/S 1.8" SSD with model number SVP180S2/128G). The following
CrystalDiskMarks (ver. 3.0.1) performance was recorded by Gary with his
T22 (having a 900 MHz Intel Pentium-3), under
Windows XP, for three SSD's:
First is shown the diskspeed of the 60 GB, 5400 rpm mechanical (PATA) HDD:

Next is shown the diskspeed of the 60 GB 2.5" PATA OWC SSD (model OWCSSDMLP060):

... and finally the diskspeed of a 128 GB Kingston
1.8" SATA SSD (with the 1.8"-to-2.5"-SATA-to-PATA adopted, mentioned above) is shown:

Notice that there is no information about whether the XP installation on the two SSD's were partition-aligned or not (partition alignment is known to may have a significant impact on the SSD speed/performance on some drives, especially under XP... but the issue of SSD partition alignment is not a topic for this post).
Gary made the following remarks to these three SSD's when used in his T22:
a) The T22 XP performance with the OWC PATA SSD is noticeably slower than the Kingston mSATA SSD results. The OWC PATA SSD keeps up with the mSATA SSDs in the DMA-5 IDE controllers of the T40, but the mSATA SSDs do better than the OWC PATA SSD when installed in an older T22 with a DMA-2 IDE controller.
b) The HDD activity LED does show activity when using the OWC PATA SSD in either Windows 7 or XP
(Johan's addition to this comment: The HDD LED does not shown any activity when using the 1.8" Kingston SSD with the eBay 1.8"-SATA-to-2.5"-PATA adapter).
c) The OWC PATA SSD works fine in a T22 running XP, and there are no weird driver messages at every boot-up like there were with the Kingston mSATA SSD.
d) The T22 XP 4K Read/Write performance with an SSD is almost the same as a T40 XP 4K Read/Write performance
(Johan's note: The T40 results are not shown in this post, but will be added to pne of the first mentioned threads). Very interesting that a really old T22 on XP can be improved with an SSD to the same random 4K read/write performance level as a T40 on XP using the same SSD.
To emphasize: The purpose of this post is
solely to share information which I have not seen reported anywhere. I hope and believe that this post is of interest for those seeking knowledge, and the purpose of this thread is therefore
NOT to say anything like: "Anyone should immediately
rush out and replace their old, slow mechanical HDD's in their e.g. T2x ThinkPad's by expensive SATA or PATA SSD's".
In my opinion it is (of course!) for anyone to decide on his/her own whether it is worth the expense to upgrade an old laptop, such as a T22, with an expensive SSD. All this just added to avoid obvious, non-technical comments.
Again, all credit for the achievements reported in this post goes solely to forum.thinkpads.com member
GACrabill...
PS: I hope that this report
might fuel an interest for other members to test these SSD's also in other "old" PATA-ThinkPad's, such as the R5x/p's, A3x/p's etc...
