Western Digital Working on 20,000 RPM Raptor Drive

Sources close to bit-tech.net and the hard drive industry have revealed information that Western Digital is working on a 20,000 RPM Raptor hard drive to counter SSD drives. Just like the company's latest 10,000 RPM VelociRaptor (300GB, SATA 3Gb/s, 16MB Cache), the 20,000 RPM unit will come in a 2.5-inch form factor with custom 3.5-inch enclosure. Other details are still unknown, since the drive is still in development stage. No release date has been unveiled, too.Source: bit-tech.net

dude, how old is your cheetah? i mean they build them for a while now and comparing a seven year old drive to a new one isn't that fair.
Yeah really i remember having a 3.2GB one on a Adaptec 2940. And did not think much of it even back then.

the problem with ssd (at least up to now) is that they CAN be fast, but not in all cases. especially writes are horrible low and access-times for writes are WAY lower than for reads! yeah they advance over time and every new product is better than the old ones, but at least up to now they are NOT faster than a recent 15k sas or scsi disk, they not even come close in the majority of tests. only for multithreaded random access patterns the concept of ssd is superior. but as always: it depends on the application... ;)

hold up, off topic question
ssds are just about as fast as memory then? :eek:
I can imagine feeling a lot less pain when windows starts loading stuff into the pagefile, even with a single ssd

yes thats pretty much the key behind them. they're in the 100's of MB/s range as opposed to GB/s, but remember the data when power cuts out.

The i-ram is an extreme example as it uses real ram but yeah... the access times are incredible. windows loads a lot faster (lots of small files) and you dont have to worry about defragmenting anymore.
