Transcend brings SSDs to the ExpressCard form-factor

While most manufacturers are using the 1.8" or 2.5" mobile hard disk drive (HDD) form-factor for solid-state drives (SSDs), Transcend is going a different route with its latest offering. The company has displayed a USB 2.0-based ExpressCard SSD that is available in capacities up to 16GB.

The SSDs are Windows Vista ReadyBoost compatible, feature Error Correction Code (ECC) and wear-leveling algorithms to ensure data integrity. And thanks to the USB 2.0 interface, the SSD shows up as a regular USB flash drive in Windows.

Transcend is also bundling an ExpressCard to USB adapter with the drives for those that would like to use it externally or don't have an ExpressCard slot.

Transcend's ExpressCard SSD will be available in capacities of 2GB, 4GB, 8GB and 16GB. Pricing and availability have not been announced, but will surely follow later this month.

Readyboost? That means this thing will be wicked fast. I dont think Vista supports a readyboost file over 4gB though...

You're right - 4GB is the limit. This product is stupid - imagine Joe EndUser gets it home and learns that only 1/4 of the drive is usable for that purpose.

Also, I find it pretty far-fetched to believe that ReadyBoost is going to send millions of consumers out to buy flash drives like this just for the purpose of using ReadyBoost. I really don't think the benefit is that compelling.

Dunno, it sold me one. Nevermind the fact that I only use it for portable storage now :)
If nothing else, it drives the standard of USB flash storage options to higher levels, since everyone wants to say their product is "Blazing-Fast Certified"

If you knew what ReadyBoost did you wouldn't be saying that. Imagine putting your pagefile completely into RAM. Albiet USB is slower than actual RAM, but that should give you some idea of the difference of ReadyBoost. I can certainly tell the difference on my PC.

And who exactly is saying this product is only intended for Windows Readyboost?

I assume you could make a 4GB partition for ReadyBoost and a 12GB one for regular use?


Bootable?

This could be useful if the device would be bootable from the bios.

If the only use is ready boost then count me out.

But if I can install my OS on it and use my HDD as storage than we may have a really useful piece of hardware.

Why not just get a 2.5" SATA SSD if you want to place your OS on SSD? Unless these are these supposed to be a lot cheaper than SATA SSD's, it just seems to me that you'd be going through a lot of headaches to get your OS booting from an ExpessCard.

That would be a feature of the BIOS. I know some laptops support it (in fact only a few don't), as well as many desktop boards.

actually, you're probably going to have to SELL your grandma to be able to afford one! :)


Might as well be external usb

Expresscard is a cool interface and supports BOTH PCI Express lane and usb.

I wish for a pcie card for my pc which can offer an expresscard slot on a desktop.

However, this product is not so great. They are only using the usb connectivity in the expresscard slot. Might as well just have cheaper device with a usb plug on.

USB is terrible for I/O because it imposes a high overhead in terms of cpu utilisation when being accessed heavily.

Thus the readyboost advantages will be somewhat offset by usb comms overhead causing slowdown.

So the only neat thing about this is it can sit inside the laptop not hang out.

Now, if they actually wrote drivers and used natively the pci express interface to connect that SSD memory I'd be REALLY impressed and REALLY interested. Unfortunately many people will think that is what this is, and be unfairly underimpressed by the expresscard interface.

I don't think you're right about the USB overhead - the USB host on the PC uses DMA to transfer to/from memory. Also, in practice, when reading to or writing to high-bandwidth devices, I don't see any significant CPU utilization due to that activity.

Too bad it doesn't have a SATA->PCIe interface...wouldn't this be great for the swap file, or to boot an alternate OS?

Do most Napa MBs support an ExpressCard SATA/e-SATA boot?




not for me...

I might think about buying it if they integrate a PCIe to SATA chip.... this is just USB mass storage.

So wait, are you really asking that question or just looking for a reason to spam your website URL that has nothing to do with the topic at hand?

This thing would be on the thick end of a grand I would assume.

With a screen name like "OhCash", is the price really of concern to you?!?!?
