Jeez $60 for 16GB doesn't sound like a great deal to me. Back in the begining of 2009 I bought a 64GB for $130 and later that year another for $150 for Raid 0 on my Win7 x64 machine. Seems like prices have gone up for comparable drives since then.
Even the older Jmicron controllers should saturate most ATA-100 or Sata 150 speads (remember peak PCI bus is like 133MB/s) can even handle in reads. IIRC a single of my G.Skill Jmicron has peak up to 150MB/s read and 80MB/s write. So even the older SSDs should fit the bill.
Also remember reading an article that Win2k was the best OS for SSD's and Win98 was second choice, Be aware some extras will/might not work though. Wear-Leveling, Trim and such which can lead to early failure.
I've thought about SSD, but these issues scare me off. I'm still looking into either a smaller IDE or Sata drive.
EDIT: back real quick. If you are using windows98se you'd be better off with finding a sale on a 500-640GB WD Caviar Black, a Sata controller, and the LBA-48Bit patch for as good as performance for the SSD's your looking at. 😀
