Cache Size on RD240 300 Gb Drives Part# 67Y1481

Can't seem to find the Cache / Buffer size on these drives. It' not listed in the tech specs I have located so far.

 

Anyone know where I could find this?

 

Thanks

I found a replacement part list stating a 32MB cache for an alternate part# 46U3439

 

I thought Lenovo was using Seagate and Hitachi drives? I can only find 16MB and 64MB cache models.

 

Any idea which drive the Lenovo version is?

 

Thanks.

In case it is of assistance to someone else in the future, the 300 Gb SAS 6Gb part# 67Y1481 for the RD240 are Seagate Cheetah 15k.7 ST3300657SS. These are 16Mb cache drives but rate faster than the Hitachi 64Mb cache units.

 

Does anyone know if the drive caddy can be purchased separately anywhere other than IBM? They are backordered for 2+ months and I have a pile of these drives that I could use in an RD240 I have in stock.

 

Thanks

seagate drives are typically quite fast.   it's not the cache that makes a difference but their platter density and controller chips.

 

all you can try is a google search or ebay for the drive caddies.   others have reported finding them online so i imagine they're still available through outside channels.
