I have prior bad experiences with SSD installed with WinXP before. I was never quite happy with the responsiveness of the OS due to frequent and excessive drive accesses. Disabling the HD paging helped but the OS still took its own sweet time relinquishing control after boot up. That was on a HP Netbook 1000 with an internal SSD drive and 2GB RAM, purchased in 2007. Installing Ubuntu solved this problem permanently.
This MLC SSD unit has far better specs than the internal SSD unit in my 2 year old HP 1000. I knew it would suffice. I installed the drive last night in my Powerbook G4 and then Debian 5.0.5. It outperformed the original disk drive, runs completely silent and is a whole lot cooler. Whether it is power efficient still remains to be seen. But I am very pleased.
If you plan on installing any port of Linux, it's a very good choice. If you run WindowsXP, you'll be very disappointed.
Sequential read: 58MB/s (14,600 IO/s)
Sequential write: 20MB/s (5,000 IO/s)
4KB random read: 15MB/s (3,700 IO/s)
4KB random write: 1.1MB/s (285 IO/s)
The 4KB random write performance is not that great compared to drives that use the Indilinx Barefoot controller (such as RunCore Pro IV), but the numbers I got in my own benchmark is 45 times better than the number (6 IO/s) reported by tech review sites. Maybe Transcend and JMicron solved the problem with JMF602B, or maybe the low random write performance problem is specific only to Windows. Who knows? All I can tell you is that this drive works great in Linux, and that is all that matters to me.
In comparison, here are the benchmark results I got for my Hitachi 5K100 5400rpm 100GB (mechanical) hard drive:
Sequential read: 37MB/s
Sequential write: 32MB/s
4KB random read: 0.46MB/s
4KB random write: 0.8MB/s
Note the drastic difference in random read performance.
I have a 1GHz 12" PowerBook that has been struggling with overall performance. It is 8 years old. Luckily, I don't use it for day-to-day work, I only really need it for building software diagnostic images. The Western Digital Scorpio Blue disks I've used historically are starting to wear out, and their performance is not what it used to be. I've been looking for a small, inexpensive SSD to replace the magnetic drives for several weeks. I ended up buying this drive, and ordered a second last night for an older iBook G4 used for the same purpose.
I have not performed a system installation from an external hard disk in a couple of years to this generation of Apple portable. It seemed slower than I remember, but I attribute most of that to newer Intel-based machines being a considerable amount faster. Running software updates downloaded from the interwebs using the auto-update mechanism installed much faster than I recall them installing while booted to a magnetic disk. Running Monolingual to erase unneeded languages and platform code was much faster using this SSD than with the previous disk.
Overall, this drive is a mixed bag. It's not as fast as I'd like, but it's also connected using an ATA/100 interface and running on an 8 year old laptop. If you need a disk to get an old Apple portable computer working, but don't need the larger capacity a regular hard disk gets you, this SSD may be worthwhile for your usage case. I didn't need 160GB of space to build a test image, and the increased overall performance is worth the higher cost-per-GB to me. This 32GB SSD, currently, is priced comparably to a 160GB PATA/IDE 2.5-inch hard disk. For some reason, it doesn't seem to work in Target Disk Mode, though I need to do more testing with this.
I cannot attest to the drive's performance or usability on a Windows/Intel based platform.
Transcend's website is goofy, but it works well for registering your products. Their RMA process is pretty slick, and the one time I used it myself, I was able to get my memory card switched out at their company offices in Orange County, CA. I have no quarrels about the company or its policies regarding repair/replacement of bad products. They were easy to work with in the past.
There is one other company that makes a currently-available PATA SSD on Amazon, and they don't seem to have any US-based support. OWC, who is known in the Apple community for their great support, only has their 240GB PATA SSD available at a cost of $400+, which is a bit high for my tastes. None of their lower capacity disks are available. I felt a little cornered in terms of my options for this purchase. I suppose this ended up being the best possible outcome, since we are talking about parts for computers that are completely unsupported by the manufacturer at this point.
I think this is a solid 4-star product, especially if the reliability of the drive is similar to what I've experienced from Transcend's other flash products. In the back of my mind, I think I was expecting unicorns and magic fairy dust to make my 12" PowerBook feel as fast as my MacBook Pro. It's definitely an improvement over the old hard disk, but there's no magic that will get the PowerBook running as fast as a new computer. That's just the way it is.
As a bonus, battery life is about 30% or so higher, it is quiet and much, much cooler running. The bottom used to get so hot you couldn't touch it, but now it is only warm to the touch. I don't miss the whirring and clicking of the mechanical drive at all!
The only downside is that I bought a 32GB drive, and my old mechanical drive was 80GB. Wasn't a problem, since I was only using 27GB. When I reloaded, I got rid of a bunch of old programs and files, so I have 14 GB to spare right now. I use mainly iDisk for traveling storage anyway.
This is one of the best $100 I have ever spent. I recommend it, if you have a PB G4 that is slowing down on you, this will add years to its useful life. The G4 is not bad to take apart to change drives. Just have to remove the keyboard and touchpad. It took me about 15 minutes to do. You can find the instructions on the Internet. Google "G4 manual" and you will see several available for downloading. I used PowerBookMedic dot com for mine and it worked well.
