SAMSUNG 843T 240GB 2.5
  • Owned For: less than 1 day

5 out of 5 eggs Samsung SM843 Enterprise SSD 12/26/2014

This review is from: SAMSUNG 843T 240GB 2.5" 240GB SATA 6.0Gb/s Enterprise Solid State Drive

Pros: "Enterprise-class SSD designed for use in situations that tend to be read-intensive like computer server boot drives, higher-end client workstation needs, and certain embedded applications." This is a direct quote from an article written in 2013 at StorageReview dot Com. This unit has similar performance to the 840 PRO's and its over provisioned by default. Has a 7mm design factor (thickness). And the SM843 offers write endurance of 1PB (1000TB). This alone makes it very desirable.
A better-protected SATA interface connector is one of the SM843's design enhancements. Also other improvements in case manufacturing were done for this drive that may improve thermal aspects ( unproven )!

Cons: Drive is not balanced for R/W performance but instead is more Read centric so write performance is secondary. Now this is not really a negative as the ability of this drive has better performance that many current desktop units currently available. And also that this unit was designed with long term reliability in write endurance performance.
AS stated the unit has a better protected SATA interface which could mean some difficulty in tight spaces of getting the SATA connector on the drive interface connector.

This unit was designed in 2013 using the current technology of the day .. which is not a bad thing but the purchaser should be aware of this.

SAMSUNG D3 Station 2TB USB 3.0 3.5
  • Owned For: 1 day to 1 week

Pros: Attractive package, light weight will need a flat surface, does not show finger prints. Comes w Software, has MAC driver to write to NTFS drive. Comes formatted NTFS.
So far it appears to be "quiet" and no vibration that can be heard but if you pick up the enclosure you can tell its spinning. Temps are what I would say is normal for this two platter spindle HDD. LED light on face of enclosure is a bit brighter than I would like it but it blinks when it either reading or writing and is on solid when not doing this ...
What you have is a Nice 2 TB 6 GB SATA 3.5 inch HDD for $20 bucks less that what is currently Retail on this drive,

Cons: Comes w extra International plugs, no power switch, Short USB 3 Cable. Comes w software ! Secure unlock for windows. Samsung Drive manager, "portable SecretZone". Mac Driver, Samsung Drive Manager and User Manuals in all the languages of the rainbow.

LED light is a little to bright for users who have Theater systems this will be a negative and no adjustment to reduce this unless you and a series resister to drop the voltage. ( But that voids the warranty cause you have to open the case.) So if this is in a Media Center area make note of this or have some colored Tape to place over it - suggest a Green Translucent tape.

Other Thoughts: The USB cable as many have pointed out is short. And many users have had issues w attaching this HD to the front USB 3.0 ports and getting the HD to work well. Rear ports appear to work better but then the short cable limits this usage.
Using rear port USB 3 - HD Tune V 2.55 shows this at 37 MB/sec to 43 MB/sec; access time or 12 ms w a burst rate of 40 MB/sec.
Could be the cable.. not sure if this is "normal" as I do not know if they are still using the ST2000DM001 drives in this enclosure.
Do be advised that External USB HDD enclosures use a "encoder" on the USB interface so if the drive is taken out of the enclosure you cant read it...also if this interface fails you need another encoder from the same USB model number to read the data on the drive if the Drive is good.
If you going to do that then remove the HDD from the enclosure first then use the HDD as an internal HDD. Of course you can wipe the drive and make it fresh.
When plugging in the USB 3 Mini cable connector use care to inspect how your doing this as the shield on the female end in the HDD enclosure was a bit tweaked not sure if this is by design or cheap connectors being used in CHINA.
Over all its a good design and worth keeping the case for other uses if your taking it apart and using the HDD for an internal unit or in a Raid Array.

TP-LINK TL-WDN4800 Dual Band Wireless N900 PCI Express Adapter, 2.4GHz 450Mbps/5GHz 450Mbps, IEEE 802.1a/b/g/n, WEP/WPA/WPA2
  • Verified Owner
  • Owned For: 1 day to 1 week

Pros: Like I said - Works OOB for a Mac (hackintosh) no kexts needed - plugged it in and turned it on and presto the Mac see's it as a Air Port Extreme w Wake on LAN and Air Drop supported. Can't test it for Air Drop as I only have one HACK.

It sees both N and G bands. - Does work in sleep mode When wake up happens.

Very Small circuit card - half height w 3 antenna - has half height bracket.

Comes w software but not for Mac. For Windows 8 you will need to download the drivers from their support website as current inventory of these cards do not have the drivers on the cd for W8.

Cons: This item always cost WAY to much - their is a Rosewill unit that has the same chip - Atheros 9380 and Three Antenna's - but as I needed to be sure that this one would work in a Hack environment w OSX 10.8 and 10.7 out of the box - that made me choose the TP-LINK WDN4800.

Do pay attention as to where you can install this card as my Mother Board had only one exposed PCIe 1x slot to use. Which is between the fist GFX card and the CPU Heat sink - this space is rather tight.

This placed the 3 antennas in the middle rear of the chassis.

So you would want to point this end toward your Routers antennas.

Other Thoughts: Seems to be A Ok - getting about 300 to 400 KB per sec. It can see both my G and my N networks (Mac).

As stated this card is rather small and the antenna can be placed in the middle of the rear of the PC - this can be a problem for antenna being behind the CPU Chassis which can be a problem for signal reception.

This card could support extended antenna's ( stronger signal strength or DB ) also you can get a remote antenna that has 3 larger (DB) gain antennas. If you want to get stronger signal.

For Mac (Hack) if you have a wireless card you need to remove it and then delete it from the System Preferences - reboot - to clean out the network table that mac uses. install card - reboot reset Wireless settings - I can log into the Apple App store w this card.
