This may be a dumb question, but what is a solid state hard drive?

The only dumb question

by boxfiddler Moderator In reply to Solid State

is the one not asked. You've been around long enough to know to post a question to Questions.
I don't exactly know... but this might help.

I didn't relize it until later

SSD....

by ---TK--- In reply to Solid State

It is a drive comprised of all flash memory. There are no moving parts, and they usually have a sick seek time!

But they are a little different than flash memory, such as you can format them in NTFS file system. They say you don't need to defrag them, but when I purchased one after the OS install and all my programs I ran a defrag. sequential read and write is faster than random read and write...

The down side is that they have a limited amount of read and write. So if you were running a high volume database on a SSD, it wouldnt last a year (if that)... but they are good for home users. they will last about 4 years, last time I did the math...

My xp box will load the OS in about 10-15 seconds VS 45 seconds on a regular Laptop drive... so huge performance jump :). But I don't know if it was really worth the price...

Expensive.

I don't know that home owners are going to want to spend the money. Hard core gamers for whom price is no object will find the performance kick worth the money. Mom and Dad aren't going to want to spend the 150 - 200% increase for it, especially since they only turn their system over every five or six years.

yeah...

I should have changed "home users" to "gamers".

SSD Drives

by dcolbert Contributor In reply to yeah...

Stands for Solid State Drive - The guy who responded "A misnomer" is a jerk. (But I guess that was obvious).

Simply like a "solid state transistor radio" it is more of a marketing title - but effectively, the other HELPFUL answers here are correct. Expensive, non-mechanical persistent storage.

A couple of observations.

They're very popular in UMPCs/Netbooks.

The limited writes are a concern when something (an OS, for example) is likely to make many ADMINISTRATIVE writes to the same physical area of the drive). There are some schemes that have been introduced into SSD controllers to try and mitigate this. But the jury is still out on the longevity of SSD drives. It is possible that they may have lifespans approaching traditional platter based magnetic media, it is possible that they will be likely to die much earlier.

But, to think that magnetic media is forever is a mistake, too. All media has a MTBF rating. The way that SSD works, there are concerns that XP and OS X will be very likely to cause that MTBF to be reached more quickly.

The jury is still out on performance and power usage as well. Intuitively, SSD should be faster and need less juice, but it doesn't always work out that way. I couldn't tell you why.

My SSD based Eee PC boots faster than a traditional hard drive into XP Home, but not tremendously faster - and the battery doesn't last any appreciably longer than any other notebook I've ever had. A movie and some light web surfing will kill it.

Ah, but it is a misnomer.

by CharlieSpencer In reply to SSD Drives

If it's solid state, what's being driven? There's no motor or other moving parts.

Yes, but

responding to the question with a one line...

"a misnomer"...

Doesn't really answer the bloke's question.

Horseless Carriage

by santeewelding In reply to Yes, but

Given the credentials -- "techno, geek, 1995(since?), IT consultant, 2 thumbs" -- a play on the misnomer is precisely what I thought he was doing.

And, given that I am a jerk, and that he is a bloke, the better question to ask is, from what disconnected place do you come?
