Are SSDs Finally Worth the Money?
Lucas123 writes "The price of 2.5-in solid state drives have dropped by 3X in three years, making many of the most popular models less than $1 per gigabyte or about 74 cents per gig. Hybrid drives, which include a small amount of NAND flash cache alongside spinning disk, in contrast have reached near price parity with hard drives that hover around the .23 cents per gig. While HDDs cannot compare to SSDs in terms of IOPS generated when used in a storage array or server, it's debatable whether they offer performance increases in a laptop significant enough that justify paying three times as much compared with a high-end a hard drive or a hybrid drive. For example, an Intel 520 Series SSD has a max sequential read speed of 456MB/sec compared to a WD Black's 122MB/sec. The SSD boots up in 9 seconds compared to the HDD's 21 seconds and the hybrid drive's 12-second time. So the question becomes, should you pay three times as much for an SSD for twice the performance, or almost the same speeds when compared to a hybrid drive?"
Remember, no spinning platter means you don't have to worry about bumping a gyroscope - an SSD is inherently more shock resistant. I'm under the belief an SSD uses less power than a HDD.
I have one SSD. It's in my netbook, I removed my perfectly functional factory HDD and replaced it with a smaller SSD since I really don't need my storage space, 90% of what I do with my netbook is on the web browser, and a netbook with Kubuntu and the netbook/tablet desktop is way cheaper than a Chrome book. I wish those were cheaper, I would practically be a marketing exec for those without the outrageous pricetag, but never mind that.
There's advantages other than performance to an SSD.
The preceding post was not a Slashvertisement.
I bought my first SSD-equipped laptop back in 2007. It was a Dell XPS. The laptop still works great today and flies in comparison to this brand new, work-issued HP laptop -- even with it's 7200rpm drive.
There isn't any comparison whatsoever. And throughput is almost moot, it's the IOPS that matter.
Dropped by 3X? Dropped by three times what?
Is that the same sort of thing as "todays temperature is twice as cold"?
I think you meant "the price has dropped by 2/3rds" or "prices today are 1/3rd what they were 3 years ago".
The biggest performance boost of an SSD compared to a traditional harddisk is random access times, this is what matters a lot more than sequential read performance.
That and a computer without any moving parts is just so nice and quiet.
Since bandwidth is not unlimited, nor is it always connected, I would say the paradigm is as valid is it ever has been.
Cloud Storage is just a re-branded version of what people have been already doing for decades, and thus factors in the same basic manner. There are what, about half a dozen levels of memory between a remote server and your CPU? Each one is a trade off between speed, size, and cost.
Putting a SSD as my OS/game drive has made by far the largest difference I've ever seen in a single upgrade.
In the past it was: "More ram..ooh yeah bit smoother...Faster CPU, bit peppier..." Etc, helped but not blow your socks off.
You put an SSD for your main apps, OS, and games, and it will astonish you how quickly things go. Firefox and other apps load instantly. When I had a macbook pro I swapped to SSD and normally the icons for my startup stuff would bounce for a bit as they loaded etc. After SSD like 5 icons would do a half bounce and bam all 5 loaded done.
So for a desktop, do what I do. Throw a big spinner in there as a drive for games you don't need a fast HDD on, media, etc. Then you will have the best of both worlds. It is by far the least buyers remorse I've ever felt on a PC upgrade.
It's easier to fight for one's principles than to live up to them.
If you compare sequential reads it's obvious HDs seem to have a chance against SSDs. It's in non-sequential reads where SSDs completely outclass any HD.
Or secure enough.
Having done a number of HDD->SSD upgrades for friends and family, I can tell you this quite simply. Anyone asking the question has never used an SSD, because if they had they wouldn't be asking it.
How a desktop "feels" to the user isn't about raw throughput, but it is very often about IOPS and more importantly latency. It may not seem like waiting 5-8ms for the rotational latency of a drive is a big deal, but spread that out over a pile of IOPS and it is a huge deal. The original post even shows how much, boot time with an SSD was 9 seconds, HDD 21. That's 50% faster. Now probably most people don't care if the boot time is 9 or 21 seconds, but I bet most folks would like their system a lot better if every application load time was 50% faster!
SSD is the single biggest no-brainer upgrade to me, it's even surpassed the "add ram" no brainer. The only time SSD's get questioned is for bulk storage. If the users needs include large music, photo, or video archives then it is worth asking questions about the cost of storage. Even in those cases, going with a hybrid drive or two drives is always the right answer.
Some performance increase?
Have you ever used one? Best upgrade (in terms of noticeable speed/responsiveness) increase since doubling the RAM on that old pentium box in 1996....
