A-DATA S592 128GB SSD Review

Interior Impressions

Before we continue: Please remember that opening any SSD will effectively void your warranty.

Unlike the metal clad brethren we have opened up in the past this cases top lid has little notches on it which engage slots in the rest of the case. For a second there we were afraid something was going to break before the lid popped free.

Wow. If the outside of this drive should have taught us anything it should have been that A-Data are taking a totally different approach than the rest of Indilinx users. Unlike all the other Indilinx SSDs we have reviewed which basically had identical PCB that only varied in their colour, this one is not only smaller but it weighs less as well. It really looks like A-Data took every opportunity to trim the fat off and get the weight down as much as possible. However, even though the PCB is different, the actual parts on the board are the same as those the competition uses. In grand total we have 16 flash chips, one RAM chip and one Indilinx Barefoot controller chip.

The I/O chip is of course none other than the Indilinx “Barefoot” IDX110 controller. As expected, this SSD comes with the Indilinx IDX110M00-LC unit as the older –FC models are long gone now. The Indilinx IDX110 is an ARM based controller with native SATA 3.0Gb/s, supports capacities of up to 512GB, is rated for speeds of 230MB/Sec read and 190MB/s writes.

The RAM that graces this board is made by Elpida. To be specific this single 64MB SDRAM chip is labeled as S51321CBH-6DTT-F, though the actual Elpida part number is the EDS51321CBH-M-F and is rated to run at 166MHZ at CL3 with an operating temperature range of 20°C to 85°C. Or as is becoming a regular theme: it’s the exact same Ram chip as we found in all the other Indilinx drives we have taken apart.

The MLC NAND chips used in the S592 are Samsung K9HCG08U1M-PCB0. Once again we, using the online Samsung model decoder we can see these chips are 48 pin 3bit MLC Quad Die Package, 1st gen lead free (ROHS compliant), 2.7V ~ 3.6V, 25 nanosecond NAND chips which operate with Dual nCE (Dual Chip Enable control) & Dual R/nB (Dual Ready/Busy Output). This model is rated at a density of 64Gbits or 8GB per chip and an operating temperature range of 0° to 70°C. Above the model number we can see these were made in the 16th week of 2009 and below it we can see the batch number “YCC887X1” (or at least what we assume is the batch number but is describe by Samsung vaguely as “Customer List Reference” only). It also seems that all 16 NAND chips are from the same batch which is a nice change from most of the SSDs we have reviewed in the past.

With the exception of the smaller and lighter weight PCB used, the S592 uses the exact same parts as all the other Indilinx drives we have reviewed and as far as we are concerned, this is a good thing.
