Soren Kristensen observed some sort of incompatibility. This is really not relevant, but I do not want to criticise everyone except Marvell. JBUK made me aware of this-see his post in discussion "KingSpec SSD on T23 ?". Even if so, I do not recommend this product (Addonics ADMS25IDE, supposed Lycom ST-173), as it is imperfect in a native-PATA host: it is detected as not wired for Ultra DMA. Perhaps mSATA assembly is operating in-spec, but with worst-case slowest-allowed responses, and upstream (ATA bridge) does not like it. No, that is not the problem: I proceeded to swap six PATA discs, all without problem. I wondered if 88SA8040 lost its mind, if it would require power restart. I first tried trim, which resulted in device disappearance. SandForce and Mushkin are not scapegoats. I also experimented with a Dell Inspiron 9300, which contains 88SA8040, just like your ThinkPads. Lycom ST-173 just does not work in my T43. I tested with a Samsung PM810 MZMPA128HMFU-000D1 (Dell part 190DF firmware AXM18D1Q controller 3C29MAX01-Y340) All T43 with discrete graphics contain Marvell 88SA8040. All T43 with IGP contain Silicon Image SiI3811. Xenomorph and Nameless, you both tried T43 containing Intel 915PM. I leave it here to preserve my trail of thought. If I had a T43/R52, I would do the 'Xenomorph' approach and limit the amount of money invested into that older single-processor technology. just like faster SSDs are tough to recognize from a user's perspective in side-by-side comparison tests. I also think that the SSD speed differences between T40=100, T43=133, T43 w/Sata mod=150 would be tough to notice to the average user. it pays to do additional research on this subject if you choose to disable TRIM in Win7/8 in order to get an IDE-to-mSATA adapter to work in the HDD bay of a T43/R52. Some brands/models are better at GC than others. Actually, they had to get more competive in this area since they don't know what operating system is going to be used with their SSD product. One of the reasons that I recommended 'new' mSATA SSDs rather than 'old' models from eBay in the OP was that all of the major manufacturers are now doing a much better job of creating SSDs with better 'garbage collection' mechanisms in the firmware. but I agree totally with 'Xenomorph's comments. I respect the decision that 'Nameless' has made. This is important if you go without OS TRIM. I've found one mention of the M500 having active garbage collection, but I'm still looking for more information on it. They do better with lots of idle time (paired with OS TRIM). Drives like from Samsung usually have passive garbage collection. AnandTech has shown that SandForce drives have great active garbage collection (the drive self-cleans during write operations). I'd hate to return another SSD to Amazon, since I've already returned two to them this month! The key here is *active* garbage collection as part of the wear-leveling. I'm trying to get more information on the M500. * Boot your Windows disc and repair the startup (since the partition now starts at byte 2048 instead of 63)Įdit: I've read that the Crucial M500 has decent garbage collection, as well (for running without TRIM). * Clone the Windows HDD partition to the 4K-aligned SSD partition with something like Clonezilla * Create an NTFS partition on the SSD with an Ubuntu 11+ disc (so that it is 4K-aligned). If you already have a working Windows 7/8 install that you want to keep, and it was upgraded from XP (and so your partition is aligned at the 63 byte), do this: If you already have a working Windows 7/8 install to HDD that you want to keep, do this: * Disable TRIM (fsutil behavior set disabledeletenotify 1) * Install Windows 7 or 8 to the HDD in the T43. Recommended install method for SSD (and required if you have a SandForce drive): You cannot do a clean install of Windows 7 or 8 on the SandForce drive, as the Windows install will fail (XP, Vista, and Ubuntu versions lower than 14.04 should also install without issue). Since you cannot use OS TRIM, I would first recommend a SandForce drive (its built-in active garbage collection is comparable to OS TRIM). Running "fsutil behavior set disabledeletenotify 1" as admin gave an *immediate* performance improvement. SDD activity was at 100% (viewable from Task Manager). On both SSDs, when an OS was cloned to it, performance sucked. With any SSD on the T43 using the PATA to SATA adapter, you must disable TRIM. It did not freeze up like with the SandForce drive, but performance was bad after install. OK, I just got the Crucial M500 drive (Marvell chipset).
