Install two 2.5” SATA drives into a 3.5” drive bay and get increased performance or data redundancy with RAID

SATA Hard Drive Adapter Enclosure with RAID

SATA Hard Drive Adapter Enclosure with RAID

SATA Hard Drive Adapter Enclosure with RAID

Upgrade your system performance

The adapter enclosure allows you to install two 2.5" SATA drives into an internal or external 3.5-inch bay, such as a drive drawer caddy or tray, or 3.5" drive enclosure.

To utilize the full speed potential of your SATA III hard drives, the drive converter supports SATA III for transfer speeds up to 6Gbps.

Suitable for drives with a height of up to 9.5 mm, virtually any 2.5" SATA drive can be made to look and function like a 3.5" drive.

Enhanced performance and data redundancy with RAID

Equipped with hardware RAID to provide improved performance and data redundancy.

Supports both RAID 0 and RAID 1 as well as Spanning, and JBOD, and lets you choose your preferred backup mode by simply adjusting the RAID setting switch.

The RAID 1 functionality is ideal in a hot-swapping server environment, providing a level of security and reliability to your data through data redundancy. With RAID 0 support, you can combine the storage capacity of the two hard drives and achieve faster read and write speeds.

Easy and flexible installation

You can install the adapter enclosure into a desktop PC or server. It offers flexible use in hot-swap bays or in a more fixed, permanent installation in a 3.5” hard-drive mounting bay with standard mounting holes.

Once installed, you simply slide two 2.5” HDDs/SSDs into the adapter enclosure, with no tools required. The aluminum housing protects installed drives in a durable enclosure.

    What were they thinking?
    The picture says it all. Compare a SATA drive alongside this product. The holes don't match up with any in a computer drive bay or caddy. Also, the case feels flimsy. ALSO, a small set of instructions would be a plus!

    I have some older PC's and most 2.5" to 3.5" drive adapters are cumbersome and ugly. The best one I have is a nice one by Silverstone and even that one is a bit of work before it can be used. This startech adapter basically makes any 2.5" SATA drive into a 3.5" drive, so it slides easily into a 3.5" slot. Good quality metallic feel. To a casual glance you might forget and think it's a standard 3.5" drive.

    I wish they made a version that converts 2.5" sata drives to IDE. I could throw it into my older systems or my Playstation 2. It wouldn't even be that much work to repurpose the design. Think about it, Startech!

    Questo Dock è un "adattatore" che permette di collegare le unità SAS da 2.5" ai connettori SATA sulla Scheda Madre, tuttavia come Dock per cambiare velocemente un'unità HDD/SSD da un computer funziona benissimo.

    Sul sito viene confermata la compatibilità con le unità SAS a patto che queste siano compatibili con i controller SATA ma non vengono elencati modelli compatibili:
    "Although mobile racks can enable a Serial Attached SCSI (SAS) drive to connect using a standard Serial ATA (SATA) connector, the hard drive controller must be SAS compatible to properly support SAS drives. SAS controllers can work with SAS and SATA drives, but most SAS drives will only work with a SAS controller."

    Dalla posizione dei fori per le viti si capisce che questo Dock non si va a installare negli alloggiamenti per le unità disco da 3,5" interne, va ad installarsi nello slot da 3,5" tipicamente usato per i Card Reader o i lettori Floppy Disk.

    Per gli alloggiamenti interni c'è l'apposito adattatore: https://www.amazon.it/dp/B00H91BXJU
    (perfetto per i Dock Hot-Swap da 3,5")
    O un più pratico ed economico kit di montaggio: https://www.amazon.it/dp/B07K9NHL3Y

    Lo sportellino appare solido ma non credo possa reggere una forte tensione quando lo si apre per estrarre l'HDD/SSD, in quanto aziona il meccanismo per l'estrazione.
    È presente anche una semplice sicura a scorrimento per impedirne l'apertura accidentale.
    Va chiuso con attenzione per assicurarsi che il gancetto dello sportello sia entrato correttamente premendo leggermente dopo la levetta di sgancio.

    Il LED indica la presenza di un'unità HDD/SSD al suo interno, ma non lampeggia quando è in uso.

    Il connettore è dichiarato SATA III (6 Gbps) ma il computer a cui l'ho collegato è SATA II (3 Gbps), mentre l'unità che stò utilizzando è a disco magnetico (WD3200BEKT) quindi non posso testare la piena velocità.
