Laptop HDD needed, Any thoughts on the new A/V drives?

post #1 of 5
Thread Starter 
Hello all,

Need a hard drive or two for a couple of laptops. Manufacturer is NOT important=

FYI: Last 2 drives I had fail were WD's, one desktop- the other laptop I'm needing this drive for. Both had error 0226 Reallocation error- and could not be recovered.

Below 5,400rpm drive is mentioned only because it has a 32mb cache which should help offset 5,400 spindle speed.


************************

Usage= As laptops... on ac power 90+% of the time.
Gaming= No- not much on lappy
Size needed= at least 500gb
Heat is a concern- hence most likely will go with a 5,400 instead of 7,200.
(Data security is more important than raw speed)
Interface= Sata
Size 2.5 (laptop)
Price range= Lappys are several years old- one in which I do not know history of.


************************

Noticed that Western Digital has some reasonably priced 2.5's that are designed for A/V use, with a 32mb cache...

My question is.... How are these going to work in a laptop?

Concerns:

A: In the spec sheets I see NO mention of "ShockGuard" that parks the heads when motion is detected... (In one of the reviews, or on WD's site I saw mention of being used in portable media players - So maybe these drives have ShockGuard but it's just not being advertised????
B: These drives are meant for 24/7 streaming use instead of being powered down and up / going to sleep as would occur in normal laptop use.

Any thoughts on these drives? Intrigued by the 32mb cache- others having 8 on average.

Features of the WD AV-25 hard drive include:

*
24x7 reliability - Designed to last in always-on streaming digital audio/video environments such as DVR/PVR, digital video surveillance and other demanding multimedia applications.
*
Advanced Format technology - Leading edge technology that delivers improved video quality and AV performance through enhanced error correction capability.
*
SilkStreamTM technology - Optimized for smooth, continuous digital video playback of up to five simultaneous HD streams. SilkStream is compatible with the ATA streaming command set so AV customers can use standard streaming management and error recovery options.
*
Ultra-cool operation - A cool drive is a more reliable drive. WD continues to develop new and innovative ways to keep drives cool while they are operating.
*
Quiet - Noise levels have been minimized to less than one sone* - virtually below the threshold of human hearing.
*
Low power consumption - The drive draws less than 2 Watts while operating and a mere 4.75 Watts during spin up.
*
1 million hours MTTF (MTBF) - Best-in-class reliability for small form factor AV storage.+
*
Preemptive Wear Leveling (PWL) - The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications.

Whatever you do.
Do NOT go with Seagate.
Every Seagate laptop HDD I have ever had failed me.
Switched to WD and never had a problem since.

My concern is if a drive designed for A/V use would be suitable for a laptop.

EG: There is NO mention of "Shock-guard" in the specs which parks the heads when movement is detected...and I would think the drive is not optimized for spin down, spin up / sleep cycles.

(3) days, 129 views..... And no recommendations or opinions on hard-drives for laptop?

I know regular drives aren't as "sexy" as SSD's -but come on guys....


No one knows if the WD AV-25 series drives maybe have shockguard, maybe it's been disabled in these drives but could be re-enabled with WesternDigital's wdidle3 utility? From a manufacturing and cost standpoint more than likely the same chip-sets are used across a wide range of products- with features being toggled on, or off.

No one has any recommendations on the best bang for you buck drive on the market now?

I have no idea about these drives, I'm using a Momentus XT (hybrid SSD) in my laptop at the moment and it's pretty nice; gives the speed of an SSD and 500GB of storage.
