16MB Buffers! LOL

Hope thats enough for you!

place a couple of those in raid in a sff computer!!!

[BigRed]

SLOW!
only 5400 rpm :rolleyes:

Whaaa?

"Toshiba launches 60GB, 2.5-inch hard drive with world’s fastest rotation speed -"

"..disk drive with a disk rotation speed of 5,400 rpm."

eh?

Also, I don't think 16 MB buffer is really practical.

Remember these are laptop drives.

It's not that bad and it's much better than most 2.5" drives. The 5400 rpm drives started manufacture last year and the high end drives got the 8MB buffers at about the same time that the WD Limiteds came out. Prior to that it was 4200 rpms. With a little luck the 7200 rpm drives will come out with the 16MB cache this late this year or the beginning of the next.

Seagate U160 180s anyone? 16MB Cache, 10,000 RPM, 180GB, 7.4ms acces time. :D :D

How much $´s?

[---X---]

$1100-1200 per drive :rolleyes:

[Vovan]

Cheap...

Can you still get caching controllers? back in the day there were SCSI qnd IDE RAID controllers with SIMM slots on, now if you had a nice ultra SCSI 160 with a 128Mb DIMM on it, and RAID spanning over 4 disks, you'd have your disk system running faster than some peoples RAM LOL.

Actually, my 5400 ATA66 15G WD is faster than the RAM on some of my old socket 7 boards. :D

Sweet only a grand each for those seagates? I'll buy 8!

too much $ for me

[Spec_Ops2087]

theoritaclly(SP) I have 16MB cache....2 Western Digitals with 8MB cahce each:D

Those sound yummy but that 5,400 makes me say EWWWWWWW

Yea but at that size it stacks up to the larger drives that run 7,200 rpms.

[arkan]

with those laptop drives only running at 5400 rpm the 16 meg buffer helps make up for the added access time of the lower rpms

That's a great question. Obviously, the answer is no-I haven't seen a caching controller in years. (And had honestly forgotten about them.)

But why not? Being able to plug in a DIMM of DDR-RAM would be sweet, But if that wasn't fast enough (that's the only reason it wouldn't work that I can think of) someone could build a controller board with, say, 64MB of that BGA DDR being used on some of the Ti4200 cards.

Anyone know why either wouldn't work?

Caching controllers are still available for both IDE and SCSI RAID units. The 3ware Escalade series has IDE caching and writes entire stripes from cache, but I doubt the RAM is upgradable. Most of the higher level SCSI RAID controllers utilize caching as well and more RAM can often be added. With regard to memory speed, you'd have to check the individual manufacturers since the onboard processors tend to be slower and may not support DDR.

My scsi controller has 8mb cache onboard, its raid, and when the sytem is up and running will be spanning 9 7200 rpm drives. And no, I dont belive in overkill.
