What is read write speed for the Flash drive. I think they are slow.

Why would they be slower than hard drives? After all, there is no mechanical movement involved, so it should be much faster. More reliable too.

Ooh, a big logo! Sounds pretty sweet!
It was only natural that when all my yo-yo strings finally broke I learned how to solve a rubik's cube over a weekend. I can now solve it in less than two minutes. :)

Takes time for data to pass through (input/output) serial/usb ports. That is why it takes time to write into the flashdrives.

Does the article say the flash memory is read/written via USB/serial interface? I'm pretty sure it will IDE/SATA or something better, why would they use an USB port for internal storage?

Ah sure, all grand here. Keeping off the Guinness but having a good time all the same. I'd miss home if I wasn't hearing what a harsh winter they are having back home. Here it has been raining a lot but has been pretty mild and liveable. As for the girls her eyes are more sea-grey than green but I do love her :)

Not if it's a Sony. Quite a few of us have had them before, and we've learnt from experience. X|

I wouldn't buy a Sony laptop. My next one might be a Lenovo, but whatever brand it is, it must be available with XP on it.

Flash memory is faster in seek time (very little latency in opening a new row), but magnetic storage is still faster in sustained bandwidth. SanDisk are now offering CompactFlash flash memory cards that allegedly provide 45MB/sec sequential read/write speeds - for $314.99 for 8GB. Seagate's Barracuda 7200.11 range has a quoted read/write sustained rate of 105MB/sec for a 7200rpm drive. The problem is the 4.1ms average latency. These numbers might be slightly fake, though, as Seagate's Cheetah 10K.7 10krpm SCSI drives, for enterprise use, show a 39 - 80MB/sec sustained transfer rate (according to the data sheet). These are commonly used with the caches switched off. You get best performance out of a hard disk if you use it sequentially, rather than randomly - track-to-track seek time is typically 0.2ms or so for reading. That's why defragmenting the hard drive can really help, for data that's actually read sequentially (it doesn't help for SQL Server database files much because they're read randomly, for example, while the transaction log benefits hugely from having a dedicated disk as it's 99% sequential writes, the log only being read from when a rollback or recovery is required).
Stability. What an interesting concept. -- Chris Maunder

The specs are impressive, but the claim about thinnest and lightest is a bit excessive. My IBM/Lenovo ThinkPad x32 claims to weigh only 2.2 lbs, although it has no CD/DVD drive and is probably thicker than the r500. I'm pretty sure UMPCs are smaller and lighter.

I believe my laptop (which is at home, and I'm at work now) has a Seagate Momentus 7200.1 100GB drive in it (it's certainly 7200rpm). The datasheet[^] quotes 45.8 MB/sec sustained transfer rate. The newer 7200.2 range quotes 59.0. However, seek time is slightly worse, 10.5ms on the old drive, 11ms on the new.

Technology marches on, but doesn't flash memory have a finite number of erase/write cycles that is much less than a hard drive?

IIRC it's upwards of 100k now. Provided you have enough ram to rarely use the swap file and don't cache the browser on disk you'll never hit it. Even then assuming the SSD is smart enough to move rapidly modified areas around it probably won't be an issue either.

Wow, that was clever... not... Email for a laptop, sounds simple enough.
