my neighbor's half-sister makes $70 hourly on the internet. She has been laid off for five months but last month her paycheck was $17706 just working on the internet for a few hours. Here's the site to read more NuttyRich.c0m

I can't help but think that that sort of RPM speed would be bad news in a laptop (which I presume is why most people would by a 2.5' HDD.)

I'd be afraid to move or nudge it while that thing was reading or writing.

A lot of modern storage arrays used in data centers use 2.5" drives, since they can pack a lot more storage into the same space. Great for high density, high-performance servers. In fact, this drive isn't even SATA, it's SAS, which is only really found on servers and business workstations.

But yes, a 10k drive in a laptop would be more trouble than it's worth, unless it just sat there and never moved or went on battery. Which at that point you might as well get a desktop system.

The advantage of 2.5" datacenter drives isn't increased capacity. If you compare the available drive capacity of a 3u chassis using 2.5" drives vs. 3.5" drives, the total capacity is drastically lower, even in an optimized configuration.
The advantage of 2.5" drives are as follows:
lower power consumption per gigabyte.
More conventient packaging (24x in 2u, which will reliably max a single purpose-built sas expander)
seek times (smaller platters means lower seek times)
drive count density (more physical drives of lower capacity means a when a drive fails there is 1) less data to resilver, and 2) less total data at risk with each drive loss)

Unfortunately, using even consumer grade 2.5" drives in a jbod or storage appliance results in less efficient total tb/rackU ratios, and greater cost/tb ratios.

I never thought about data center usage...that does make sense. Good to know.

Almost shat myself when I saw 552 Gbps, but then I realized it was actually 552 Gbpsi....

Toshiba's answer to the WD Enterprise V-Raptor?

No transfer speed benchmarks? C'mon, that's where all the fun is, "enterprise" drive or no... ;)

Agreed on the benchmarks, it's a bummer =(.

Please enlighten me here. I thought companies need to save money these days. I don't see a 10,000+ RPM 2.5 inch drive as an option; Either you get a pricey SSD for extreme performance or a regular 5400 RPM drive for a good budget laptop upgrade or whatever.

Or am I missing something here? I just don't see an enterprise real-world application for 2.5 Drives.

Systems used in the Datacenter are shrinking. The new systems being deployed are often "blades" that pack a lot more CPU, RAM and HDD space than a full rack mounted server they are replacing. Systems are soon arriving that will be an even smaller form factor than these blades.

SSD drives can be more efficient for the floor space or power used per storage byte but not both combined. Also note this model has several size options so they can meet many needs not just for high capacity.

There are a lot of storage arrays that take 2.5" drives now, it's actually becoming standard. Instead of 12 3.5" drives in 2U chassis, you can fit 24 2.5". At my work, we have a Dell MD3620i SAN (10Gb iSCSI :D ) with 24 900GB 10k rpm Seagate drives. This SAN is used for hosting lot of VMs, so we need the fast drives. That's why they call them Enterprise drives, they aren't targetting the laptop crowd with these :)

I agree that getting one of these for a laptop/desktop with single drive is quite useless...although workstation that does lots of heavy disk operations with a 4+ disk raid 10 set, I'd consider it...
