last two years when I first got my idisk Tiny 256mb, the performance is awesome with superb random/read/write. This really increse my confident on pretec product. And it pass my windows vista readyboost flawlessly.
Last nite I purposely go order another Tiny 1gb, but this time.... very dissapointed. Not only fail my vista readyboost test, but the performance is terrriblly bad.

benchmark for 1GB

Corsair Voyager GT 4GB  drool.gif

Pic 1: Added ATTO Disk Benchmark. Max Read: 31.2MB/s - Max Write: 22.7MB/s.

Pic 2: SiSoft Sandra benchmark ...

Pic 3: My USB drives collection wink.gif From left: Pretec iDisk Diamond 128MB, Kingmax SuperStick 1GB, Pretec iDisk Tiny 1GB, Pretec iDisk Wave 2GB, and finally the *king* Corsair Voyager GT 4GB!

:: Pretec iDisk Diamond: In my wallet  doh.gif

:: Kingmax SuperStick: Tied to my handphone  brows.gif

:: Pretec iDisk Tiny & Wave: Tied to my keychain. Will be used to transfer files betwen computers (good to prevent viruses attacking ur drive, which happened to me earlier this month from my colleague's infected pc!)

:: Corsair Voyager GT: Just tied to my keychain as my master backup unit.

Pic 4: The nice, shiny packaging. Fierce red to show the turbo speed wink.gif *H-A-T-E the blister packaging! Used a big scissor to cut the left-top-right sides!*

Pic 5: My personal real-life filecopy test. Seems that the rated speed (34MB/s read and 28MB/s write) is loosely based on *single* file size (possible 256MB or 512MB).

The rest of the tests are based on multi-file copying @ 1GB and 3.7GB total size. Not bad considering it takes 3minutes 5seconds to copy the 60 files (totaling to a whopping 3.747GB!).
=> Antivirus was disabled.
=> Each read and write session were done separately by removing and inserting directly to the USB port.
=> No USB hub was used.

=> My read/write speed may vary with others due to different mobo/chipset used. My mobo is Asus P4P800SE using Intel 865PE chipset with 2.8GHz P4 CPU and 2GB DDR400 RAM. Windows XP SP2 OS.

=> I bet new NVIDIA mobo/chipset has much higher USB throughput.

hi there.
i was just wondering y is your Transcend 160 High Speed pendrive write speed is just 3447kb\sec.

i tought is should be near to 8000kb\sec.
stated from the transcend website.
dat doens't mean a high spped pendrive then.

im using one to.
the transcend 110 high speed 2gb pendrive hav the similiar results.

biggrin.gif I liked Pretec because of their *tiny* design ...

If I know Pretec Wave is slow, I wouldn't buy it. I thought since Pretec Tiny is moderately fast, Wave would be faster ... heck, it's much much slower! They may have chosen MLC flash to achieve 2GB size (that time), hence the low speed ...

FYI, Iomega is the *1st* company that introduces this 'swivel design' ... I bought it at Singapore ~3 years ago in a computer fair ... Later I saw Pretec introduced their Tiny using the same design, so I immediately bought it (since 1GB that time was considered 'huge' and I wanted more storage to store my files/apps) ...

The ultra-tiny pendrive (Kingmax SuperStick and Pretec Diamond) was because I wanted to hang it or put pendrive in my wallet as a full-time backup. Also, I enjoyed 'showing-off' my ultra-tiny drives to girls brows.gif

the only 'big' pendrive I have is Corsair Voyager GT wink.gif but since it's extremely fast, I can forgive it for its size ... 4GB and 31/22 read/write speed is the best pendrives I've seen and used so far ... NO REGRET!!

thumbup.gif doh.gif rclxms.gif

p/s: I have another drive, which I've *sacrificed by opening the plastic casing to see what Flash chip they were using* due to my absolute frustration: InnoDisk 2GB ... I warranty-ed it 2x 'cuz it's not stable and the file system always corrupted! rclxub.gif Everytime I see InnoDisk and its cheap price, I stayed away ... BAD BAD EXPERIENCE! mad.gif

hi bro, sorry, I dont plan to sell it ... i'm still using it as a tool to transfer files to/from other computers ... think of it as an "innoculation unit" wink.gif

likewise I wrote above, it's particularly useful when ur friend's computer is infected with viruses and tries to infect ur pendrive once connected ...

if i used my 4GB VOyager GT, darn, it'll practically infect all my EXE files there wink.gif

smile.gif poor read/write speed ... but it's not my main purpose to get them ... i wanted them extremely tiny for portability wink.gif

I tied my Kingmax SuperStick to my handphone wink.gif And iDisk Diamond in my wallet (no use for now cuz it's just 128MB only)

I got SuperStick after I bought iDisk Diamond due to capacity ...

There were times when my iDisk Diamond 'saved' me all the troubles when I didn't bring my other drives with me ... 128MB is just nice to backup documents and stuffs ... but not enought o backup ur portable apps brows.gif

1) Did u plugged the drive behind the mobo or the front casing ports?

2) If front casing ports, does it connected directly to the mobo header/pins?

3) What drive (brand/model) are you using?

4) What OS?

5) You wrote you're using external hdd. Is the enclosure rated full-speed or high-speed? Do note that the internal circuitry inside the enclosure may not be high-speed, thus the error msg.
