In this article we are going to take a really close look at the features and performance of the new Fujitsu hard disk drive aka MAS3735NP. This particular eldest model in the family is going to represent the MAS product line in our today’s review. MAS HDDs family is the second generation of hard disk drives from Fujitsu featuring 15,000rpm spindle rotation speed. The previous model of the 15K Fujitsu drive has already made a very good impression in our test session in the year 2001 (see our Hard Disk Drives in 2001: Annual Overview). So what surprises has Fujitsu prepared for us this time?
Two major innovations in the MAS family are the use of 18GB platters and U320 SCSI protocol support. As you already know, MAM HDDs were based on 9GB platters and supported only U160 SCSI. Which never prevented them from being really fast for their time.
The cache-buffer of MAS drives in 8MB big, i.e. it remained of the same size as the cache buffer of the previous generation models. Also, Fujitsu doesn’t offer any 15K HDDs with FibreChannel interface still: only the standard SCA-2 (the last two letters of the marking are “NC”) and 68-pin Wide (the last two letters of the marking are “NP”) SCSI drives.
Here it is, our today’s main character:
The looks is very familiar, don’t you think so? :)
The table below contains the brief MAS drives specifications:
As you see, there are three models in the MAS HDD family: single-, dual- and four-platter hard disk drives of pretty standard storage capacities equal to 18GB, 36.7GB and 73GB respectively.
If we compare the average seek time claimed by the manufacturer for its MAS HDDs with the specifications for Fujitsu MAM drive, we will notice that the new generation drives should be somewhat faster, because their claimed average seek time is 0.2ms shorter. Well, the doubling of the per platter data density seems to have positive effect not only on the linear read speed increase, but also on the random sector access time.
