Seagate Momentus XT or HGST Travelstar Z7K500 HTS725050A7E630 has higher throughput
Posted on 2012-12-28
I plan to put my Outlook's .pst file (now at 3GB size) on a fast performing
storage as I often search my past emails & it took frustratingly long. So
in this case, 'read' performance is crucial
1. Seagate Momentus XT ST95005620AS or
(http://www.newegg.com/Product/Product.aspx?Item=N82E16822148591 for US$90)
2. HGST Travelstar Z7K500 HTS725050A7E630
(http://www.newegg.com/Product/Product.aspx?Item=N82E16822145587 for US$80)
Q1:
Which of the above two HDD has higher IO throughput?
(as I plan to install into my Lenovo X220 : supposedly
both can fit in, right?
1 was published to have 3Gb/s while 2 has 6Gb/s but
1 has SSD hybrid built in
Q2:
which of the two consumes less power / electricity ?
Q3:
I read most Seagate HDD are now made in China &
thus has poorer MTBF (tends to fails/crash). Is 1
made in China?
I read Seagate Momentus XT ST750LX003 will be even
faster than the above 2 as it's published to have 6 Gb/s
with double the SSD amt of 1
storage as I often search my past emails & it took frustratingly long. So

Any published Read times for the above models that I've quoted
will be appreciated. For 1, newegg indicated the average write
time is 13ms (but it's not write time that counts when I search
.pst file for emails)

Is average seek time = average read time?

gives average seek time as 13ms (= 1's average read time)
http://www.hgst.com/internal-drives/mobile/travelstar/travelstar-z7k500
gives 2's average seek time as 13ms too (& it indicated avg seek = avg read )

As indication of reliability / MTBF, found the shock tolerance for 2:
Shock Tolerance Operating: 400 G @ 2ms half-sine pulse
Shock Tolerance Storage: 1000 G @ 1ms half-sine pulse
will be good.if anyone can give the shock tolerance figures for the
above Seagate models.

Above url gave the shock tolerance of another model of Seagate HDD
Shock Tolerance Operating: 350 G @ 2 ms
Shock Tolerance Storage: 1000 G @ 1ms

average seek time is the average time the head Assembly needs to move from 1 track to another, calculated over all tracks, so in general it is nearly the time to move from track 1 to the track in the middle
here they say it's transfer speed is 171 MB/s http://www.storagereview.com/hitachi_travelstar_z7k500_review

Cant locate the transfer speed in the above link. Can just quote to me
the transfer speed for Momentus XT?
In the url below, there's power consumption for Momentus, do you
have a url for Hitachi's :
