I've been trying to get an 80GB Intel X25-M G2 for a few days. They are going for well over double MSRP ($600 versus $230) at several retailers (e.g., http://www.newegg.com/Product/Product.aspx?Item=N82E16820167...)

Newegg has an autopricing algorithm that ramps the price up into the stratosphere if a lot of people are buying something. It takes a while for the price to settle back down to 'reasonable'.

Either find it elsewhere, or wait it out... Amazon has had good prices on hard drives recently. The magnetic kind; I haven't been paying attention to SSDs.

They are pretty surprisingly hard to get. At the beginning of the summer I tried to buy, I think, 20 drives, to upgrade all the developers to SSDs and I remember being surprised that I cleared out Amazon AND NewEgg completely to get the drives I needed.

As I recall, this was because Intel had a manufacturing problem and stopped making the X25-Ms until only about a month ago.

My understanding is that it was simply a firmware problem. Reflashing the buggy drives fixed the issue.

I was looking for this same drive today and the suppliers in Australia are under the impression that Intel will ship them end of next week (for a pretty reasonable 400 AUD - approx $300)

I put an order in with Toshiba Direct for one since they had non-insane pricing.

We'll see how long it takes to ship.

I can't wait for the new X25-M. Recently threw a 160GB X25-M (first gen) in a datamining database server to replace a 6x15k SCSI RAID 10 array, and it was 2.5x faster. One disk faster than six.

Interesting! Can you elaborate a little bit on the usage pattern and how you measured the speedup, please?

chrisbolt2• 17 years ago

It was a very simple, unscientific test: ran a MySQL query with the old drives, then ran it on the new drive. Old drives took 5 minutes, new drive took less than 2 minutes.

I'd add at least another disk and build a raid1-array. With a single-disk setup you miss the greatest feature of RAID, redundancy.

After several hours of researching SSD options, I recently bought a Corsair P128 from Amazon. Firmware version was VBM18C1Q (which supports background garbage collection as the article points out).

Price is currently identical on both Amazon and NewEgg ($330.99), but NewEgg has tons of user reviews. Affiliate-free links:

One minor quibble: as far as I can tell, Apple is actually mostly shipping drives manufactured by Toshiba, which don't seem to be rebrands of Samsung's tech. The way to tell is to look in System Profiler; Toshiba drives will be labeled "Apple SSD TS128" or "Apple SSD TS256", while Samsung will be "Apple SSD SM256" (they only seem to show up in the 256GB option, and even most of those are Toshiba).

Anyway. I recently picked up a new MacBook Pro and went for the (256GB, ended up with Toshiba) SSD option, and I've got to say I don't ever plan to go back to a mechanical drive if I have the choice. It's not just the flashy-but-pointless things like boot time or first-time application launching. It's the fact that most of my life consists of reading, paging and grepping through lots of files, and that is stupid fast with the SSD. I don't worry too much about write performance, because typically I'm in an incredibly read-heavy workflow.

"There’s a Mac Edition of the Vertex, unfortunately it’s no different than the regular drive - it just has a different sticker on it and a higher pricetag."

As a longtime mac user, this kind of thing drives me crazy.

Also the article talks about Windows XP and Windows 7 but doesn't mention anything about TRIM support in Mac OS X. Is this something that needs to be enabled at the kernel level? Does anyone know the status of this command with the Snow Leopard kernel?

wmf• 17 years ago

IIRC older kernels blocked any unknown ATA commands, including TRIM. Newer kernels no longer block TRIM, so someone is working on a third-party utility.
