What kind of Flash Drive do you use?

I have 2:
BusLink Musica 1GB slow as a dry snail.
PopDrive (What the heck with the dumb bottle opener?) 1GB fast but cap is WAY too much.
I wanna get a Corsair Mini Voyager 4GB 15 mb/s write

Thumb Drive
8 GB
SanDisk
cruzer micro
Currently running 17 apps from the menu, and I haven't noticed any speed difference between local installs and running form the thumb drive except for Firefox. Browsing is the same, yet startup and shutdown takes about 4 seconds longer, but that didn't start happening until I subscribed to Malware Domains in addition to Easy List USA in the Adblock Plus Firefox extension. I like the cruzer micros and have a couple smaller ones, one for Vista ReadyBoost and the other is a backup if one fails. The only thing I don't like about micros, is that they come with U3, but it's quick and easy to remove.

4GB Corsair Flash Voyager (flash; kinda slow, although in Linux it's fairly fast)
60GB Maxtor One Touch III Mini (2.5" hdd; main drive)
1GB PNY Attache (flash; I didn't trust it all that much to store my PA's so I gave it to my wife)
1GB SanDisk Cruzer Micro (flash; I really liked the way it functioned, however it mysteriously disappeared)

-External Storage (2.5´´ HDD)
-320 GB
-Western Digital
-Passport II
-My baby

1st

Memory Core 1Gb
Read/Write Speed - Slowish/Slow as hell
Usage for now - none, it is empty laying around somewhere
Other details - poor quality cap breaks very fast, cheap

2nd

Kingston DataTraveler 2Gb
Read/Write Speed - Have no idea, but it is good to me
Usage for now - my PortableApps are there, as any data that I need when away of my pc
Other details - good quality cap hasn't still broke, cheap

* 2.5" Ext HDD
*Western Digital
*160GB
*Passport

I don't have all 160GB for PA. I use truecrypt to encrypt a 4GB file for PA. Since the drive is formatted as FAT32, that's the most I can have.

1st One:
- Flash Drive
- 8 Gigabytes
- Sandisk Cruzer Micro

2nd One:
- Flash Drive
- 2 Gigabytes
- Kingmax Super Stick (World's Smallest Flash Drive!)

As far as flash drives, I only have a 1GB Sandisk Cruzer Mini. However, I don't use it much since I bought a 320GB WD Passport (USB powered). I just bought a 1TB acomdata PureDrive for backing up large files.

Oh, and I have two memory cards - an 8GB Memory Stick Pro Duo for my PSP, and a 1GB Micro SD that came with my cell phone.

A PNY Attache (2 gig). It's fair for a $15 and under wal-mart bought flash drive. Moderate speed, still slow, a little bit, for FFPE yet all my other apps run great on it.
