Solid State Drives

@ EyeAm
I feel the need to correct you a little bit.

The first link you gave. is a link to a OCZ RAID device intended to put multiple SSD disks inside. and it uses the PCIe standard. (no use in any amiga... so far)

This is one of OCZ most affordable SSDs...
And it can perform:
Read: up to 155 MB/sec/ Write: up to 90 MB/sec
Which is more likely for a single SDD.
Raiding multiple SSDs will increase the read and write speeds of SSDs. and for that matter any normal hard drives as well...

However, speed set aside. The quiet and cool running of a SSD is tempting. and will soon find its way inside my laptop.

Life cycle of a SSD is significantly increased, and "can" surpass normal HDDs... somewhere around 2 million read/write cycles. (on the most expensive ones, though...)

I think SSD give me more to worry about than Hard Drives.

I own several flash drives.  The early ones were poorly housed with the chip just sitting on top of the board and it was making a connection that way.  

I have several flash drives and the only one that doesn't work is because I touched an electrical display at a science museum.  I have had the others for several years and they've been in the washer and they still work.

You probably want to keep them away from magents.

They are more reliable than floppies unless you consider long term (20 years).

What SSD disks and flash devices are you talking about?

Dedicated SSD disks will endure any shock you ever (under normal circumstances) will put a harddrive trough.

SD and CF cards cannot in any way be compared to SSD...

No problem in linking to the z-drive. Was not aware of it until you linked to it. Definitely a cool device.

Not to make a big deal about it.... :-)

According to this
OCZ is using a Highpoint RocketRAID 3520 PCI Express RAID card.

The largest commercially available SSD disks are 250GB. And 512GB disks is arriving soon.
Four 250GB SSD disks will provide you with 1TB of storage space.

Link 1

However, yes, OCZ is offering them as a single device with 250GB, 500GB or 1TB of capacity. And a 4TB one planned.
And unless OCZ has done something to the hardware of the Z-drive i cannot see a reason why not you should be able to expand or replace the disks of a smaller version into 1TB, or more when available...

But honestly when it comes to speed the hyperdrive 5 is way more interesting (all though limited to only 64GB)...
And taking the price of FAST SSD disks into consideration, id rather build a RAID 5 consisting of normal SATA disks for maximum storage space. Most bang for buck...
For the price of the z-drive i can build a very large raid 5 array...

EDIT: removed some fact errors...

Things are definitely going to get interesting.

And insanely expensive.....

But hopefully the smaller SSD disks becomes cheap now...
